Information for treated water customers and untreated water customers walks through the rate adjustment and provides a side by side comparison with current 2019 rates and adopted 2020 rates. You may also reach our customer service staff at 925-688-8044 from 7:30 a.m. to 5:00 p.m., Monday through Friday.
Depending on the type of services you receive, the rate adjustment will impact you differently. See how the adopted changes for 2020 affect treated water customers and untreated water customers.
As a public agency, the District does not earn a profit. Rather, the rates and charges collected from customers go directly to pay for 1) the cost of service, 2) emergencies/contingencies, 3) employee salaries and benefits, and 4) compliance. If we don’t consistently keep up with these costs, it might mean higher increases in the future.
1) Cost of Service – this includes activities like reinvesting in capital facilities, to make sure our intakes, treatment plants, pipelines, and everything in between function properly. It also includes things like customer service, education programs, and conservation rebates. In addition, we pay more every year to the Bureau of Reclamation's Central Valley Project for our source water from the Delta. We are making technology investments to modernize our processes and systems and gain efficiencies.
2) Emergencies/Contingencies – healthy reserves help us avoid steep rate increases during drought emergencies. Also, if we’re not prepared when emergencies strike, we potentially risk our ability to continue providing reliable service.
3) Employee Salaries and Benefits – we know this one tends to spark questions, but the truth is that you need hardworking, qualified people behind your water systems. Our employees earn a competitive wage for the Bay Area, and increases are consistent with the consumer price index.
4) Compliance – like any organization, there are new regulations and requirements from the State and Federal governments all the time. Staying in compliance is a priority.
The 6% revenue increase allows us to maintain the high-quality service you expect as a District customer.
We offer classroom programs for 3rd, 4th, and 5th grades that are grade-specific and are NGSS and CCSS compliant. The 3rd grade program is centered around the properties of water, including its different states. The 4th grade class looks at the history of water in California, as well as California water geography and rainfall. The 5th grade class dives deeper into the water cycle and the treatment of drinking water. These classes can be adapted for special needs students.
Classroom Programs are available for 3rd, 4th, and 5th grade students for public, private and home schools within our service area. Schools outside of our service area are not eligible for the program.
To book a date, you must submit a Classroom Program Request Form.
Our programs are offered Monday through Friday during the normal school day.
Yes. The process works best when each grade level at each school has one teacher acting as their contact person. The process works best when each grade level at each school has one teacher acting as their contact person. For example, if you are one of three 4th-grade teachers at a school, the three of you should designate one teacher as the contact person.
Requests are accepted year-round; however, a limited number of programs is offered each school year. You will be contacted after you submit a request with next steps.
There is a field on the request form that gives you the opportunity to tell us what days of the week or months of the year work best for you. Available dates will be proposed until mutually agreeable dates can be confirmed.
Due to the popularity of our programs, we are unable to hold dates. To book a date, submit a Classroom Program Request Form.
Requests are typically processed within a week. You'll receive an email with proposed dates to fulfill your request.
We normally schedule 2-3 classes in a single day. If your school has more than 3 classes in a grade level, we will spread the programs over more than one day.
Unfortunately, we do not allow classes to be combined for individual classroom presentations. All class presentations include hands-on activities that are designed for one class at a time.
No, classroom programs are provided at no cost to schools within the service area.
Milky white water can also be described as cloudy, hazy, soupy or foamy, and is almost always caused by air in the water.
Consistent cloudiness in cold and hot water. Tiny air bubbles in water can give water a cloudy or milky appearance. Water in your pipes is under pressure. Filling a glass of water reduces that pressure and can cause air bubbles to appear in your water which can look cloudy, milky, or carbonated.
Cloudiness in warm or hot water. Air in water lines can sometimes be attributed to warming of cold water lines or overheating water (above 140 degrees) from hot water systems. Milky white water often occurs in spring time when the weather begins to warm.
Troubleshooting. Collect a glass of water and let it stand for two to three minutes. Any air bubbles will rise to the surface and the milky appearance of water should clear starting from the bottom. Entrained air does not affect the quality of your water.
Brown, red, orange or yellow water is usually caused by rust. The major causes of rust include water pipes in your building or water mains.
Intermittent brown, red, orange or yellow hot water. If your water is discolored only for a minute or two after you turn on the tap, the cause may be the internal plumbing. The zinc coating on the inside of galvanized iron pipe can wear thin and expose your water to bare iron. The different colors can be attributed to varying chemical oxidation states of the iron (rust). The longer the water sits in the pipes, the worse the discoloration will be. This is why this problem is most noticeable the first time you turn on the tap in the morning. If only a few taps are affected, only a portion of your internal plumbing has galvanized pipe.
After running your tap for a few minutes, clean water from your water heater or the water main will replace the discolored water. Since iron is an essential nutrient, this condition poses no health hazard. If the discoloration bothers you, however, flush the tap until the water becomes clear and save the water for iron-loving plants.
Consistent brown or yellow cold water. Normal pipeline flow allows silt, sediment and other materials to settle to the bottom of the pipe. A disruption of normal flow can cause these materials to get stirred up and suspended in the water and cause the water to look light yellow to dark brown. The discoloration is caused by dissolved iron which is stirred up in naturally-occurring sediments.
The following conditions commonly cause flow reversals in water mains and sediment to be disturbed.
The discoloration does not indicate that the water is unsafe or that the integrity of the water main has been compromised. A disinfectant residual is maintained in our system to ensure that the water is safe for household use, including cooking and drinking. For aesthetic reasons, we recommend you avoid doing laundry until the water clears up. We also recommend that you do not use the hot water as it will draw cold, rusty water into the tank and it may need to be flushed out later.
If the water at the front hose bib is discolored after running for two minutes, the problem may be coming from our water main and you can contact us at 925-688-8156.
The blue disinfectant some people use in their toilets can cause discoloration of your tap water if your water supply was recently turned off. A condition may have been created in which the water from the toilet tank was siphoned into the plumbing of your house. This can happen when the toilet is upstairs and the water supply has been shut off for some reason. These disinfectants contain chemicals that may pose health hazards if ingested or touched. Flush your plumbing by opening each tap until the water runs clear. Do not drink this water. Blue (or blue-green) water may be due to extreme copper plumbing corrosion. If this is happening, the water will usually have a bluish-green tint and/or will leave a bluish-green stain around fixtures and on a white surface if the water drips from a faucet. This copper corrosion can be caused by your electrical system being grounded to your water pipes, especially if you have a mixture of pipe material (i.e., some copper and some galvanized iron). If the blue color is only in the hot water, it may be due to the temperature on the water heater being set too high. If you have a hot water circulating system, the return line may be too small or the water may be pumped too fast for your pipe size, or it may be installed incorrectly.
Standing water in a white bathtub can sometimes appear to have a greenish tint to it. Fluorescent lights will make your water appear green. To test this, fill a white bucket with water and take it outside. In the sunlight, the water will look clear and no longer appear green.
Another cause of green water is extreme copper plumbing corrosion. If this is happening, the water will usually have a bluish-green tint and may leave a bluish-green stain on porcelain if the water drips from a faucet. This copper corrosion can be caused by your electrical system being grounded to your water pipes; especially if you have a mixture of pipe material (e.g. some copper and some galvanized steel). If the green color is only in the hot water, it may be due to the temperature on the water heater being set too high. If you have a hot water circulating system, the return line may be too small or the water may be pumped too fast for your pipe size, or it may be installed incorrectly.
Wait for District crews to complete their work and flows to re-establish. We recommend an hour before resuming normal water use to let the normal flow patterns in our mains to re-establish themselves and for any remaining sediment to settle down.
If discolored water is also in the hot water system, you can continue to use hot water until the discoloration dissipates and is no longer an aesthetic issue. Many customers prefer to do this rather than refilling the water heater which may require expertise of a plumber if you are unfamiliar with how to do this safely.
Following this guidance generally will take care of the problem. However, depending on the pattern of water use in your neighborhood, it may be necessary to repeat the process more than once if the discoloration continues.
Yes, the District's Engineering Services Coordinator is available and eager to meet with water service applicants. Please call the coordinator to schedule an appointment during normal business hours at 925-688-8014.
A walk-in service is only for a single 1-inch water service from an existing water main. There is a fixed cost for the installation of a standard 1-inch water service line, plus the cost of a 5/8-inch, 3/4-inch, or 1-inch meter. District crews always install these.
A service agreement is for the installation of water services, fire hydrants and fire services where an existing water main is adjacent to a particular development. District crews always install these.
A water main extension agreement is required for any development that requires new water main facilities where none currently exist. Under this agreement, the installation of water mains, fire hydrants and new services is performed by the applicant's licensed contractor and is inspected by the District.
The Applicant shall pay all the District’s costs reasonably incurred in connection with the new facilities required by the District, including without limitation costs incurred in complying with the provisions of the California Environmental Quality Act; costs of acquisition of lands or easements; engineering, legal, and administrative expenses; costs of labor, materials, construction, inspection, and testing; and the District’s usual overhead charges. Prior to final design and construction of the facilities, the Applicant shall deposit with the District the amount of the District’s estimated costs per the agreements. Construction drawings will not be released until the total estimated cost is deposited. After the work is completed, if the District’s actual costs exceed the amount previously deposited, the Applicant will pay the deficiency to the District. If the amounts deposited exceed the District’s actual costs, the excess will be refunded (refer toDistrict Regulation 5.28.060)
The Engineering Services Coordinator will contact you if we have any questions or problems during the service design. You can help the design process by promptly submitting all requested documents and providing the specific location and meter size of your new water service at the beginning of the project.
The Engineering Service Coordinator is the main contact for your entire project. The Engineering Service Coordinator will provide you with your contact person in Operations and Maintenance or the Construction Department who will coordinate actual installation.
No, the District cannot determine the meter size or fire service size required for your project. You should consult with your professional engineer or architect to determine your water requirements. The District's New Service Fees sheet lists common meter sizes with their typical flow range, and is a useful aid. The District will attempt to guide applicants if the requested meter appears too small or too large for the project. The smallest meter the District allows is the 5/8-inch meter, which can flow approximately 20 gallons per minute (gpm).
Yes, a Land Levy Tax Credit (PDF) is available for qualifying parcels.
For new water service, you will need to fill out the Application for Service or the Walk-In Service Application before continuing. Find out more information at New Water Service.
Yes, District Title 5 Regulations (Section 5.32.020) state that a water meter is required for each premise to which the District provides service.
The District Title 5 Regulations (Section 5.32.020A) state that a water meter is required for each premises to which the District provides service. The District’s Board of Directors have determined that a premises is a parcel of real property or any improvements thereon which the District solely and conclusively determines is a separate unit for receiving, using, and paying for water service. In general, a duplex, town home, and detached in-law / secondary unit require individual water meters. This requirement best protects the District’s water system and public health.
The District’s Engineering Services Coordinator (ESC) is available and eager to meet with water service applicants to evaluate and determine water service needs. This is the best way to determine water service needs. Please call the ESC at 925-688-8014 to schedule an appointment during normal business hours.
You should first pick up the District’s walk-in service application, which contains forms and information for water service. These service application packets also describe what is required to initiate a water service project. You can pick up a walk-in service application at the District’s office at 2411 Bisso Lane in Concord, California, during normal business hours. You can have it mailed to you by calling the Engineering Senior Clerk at 925-688-8167.
A walk-in service is only for a single 1-inch water service from an existing water main. There is a fixed cost for the installation of a standard 1-inch water service line, plus the cost of a 5/8-inch, 3/4-inch, or 1-inch meter (a 1-inch meter is required for residential fire sprinklers) and, if required, a reduced pressure backflow prevention device (RPBPD). District Operation and Maintenance crews always install these.
No, the District cannot determine the meter size for your secondary unit. You should consult with a professional engineer or architect to determine your water requirements. The District’s new service fees sheet lists common meter sizes with their typical flow range, and is a useful aid. The District will attempt to guide applicants if the requested meter appears too small or too large for the project. The smallest meter the District allows is the 5/8-inch meter, which can flow approximately 20 gallons per minute (gpm).
The District’s design time is 8-12 weeks from submittal of application for service to completion of installation depending on the District’s workload.
Yes, call the Engineering Services Coordinator at 925-688-8014 as soon as you know a change in the location or size of your service. The sooner this information is known, the less impact on completion of final service designs.
If you have any questions, your main contact person is the Engineering Services Coordinator. You may give them a call at 925-688-8014.
The Engineering Service Coordinator is the main contact for your entire project. They will provide you with your contact person in the District who will coordinate actual installation. If you have any questions, please call them at 925-688-8014.
Once your water service is installed, and your plumber has connected to the service, please call Customer Service at 925-688-8044 for service activation during normal business hours.
Walk-in services have a fixed cost for installation and require one payment with your application to initiate, design, and install the project. Call the Engineering Services Coordinator at 925-688-8014 if you have any questions.
Facility Reserve Charges (FRC) are a connection fee to the District’s water system. Simply explained, any time a new water meter is installed, more demand is placed upon the overall water distribution system. Therefore, FRC charges are required to cover the District’s costs for developing new water storage facilities, treatment processes, transmission pipelines, and distribution mains. The District’s new service fees sheet lists meter sizes with their associated FRC charge. Each service requires the appropriate FRC be paid.
Yes, you will only pay the difference in FRC costs between the larger meter and the smaller meter. The credit received is based on the date of the last payment made (abandoned date) on the existing meter. You pay the difference between the current FRC and the FRC value in place at the time the meter was abandoned. You will also pay the difference in the meter costs. If there is an existing backflow prevention device, you will also need to pay for a larger replacement. There is no credit is given for upgrading backflow devices.
A pressure-reducing valve (PRV) reduces the water pressure to the customer. The Uniform Plumbing Code and the District recommend installing PRVs when the water pressure in the District’s mains exceeds 80 pounds per square inch (psi). The District will inform the applicant of this condition. PRVs are available at most hardware and plumbing stores, and are installed by the applicant on the applicant’s side of the water meter.
A reduced pressure backflow prevention device (RPBPD) prevents water from flowing in reverse and potentially contaminating the water in the District’s mains. RPBPDs are required on all services in industrial and commercial areas, on residential services with houses greater than three stories or with residential fire sprinklers, and at all sites that also have a well or other potential water quality hazard. RPBPDs are installed and maintained by the District. RPBPDs are installed approximately 12 inches above ground and are typically located directly behind the meter, preferably in landscaped areas.
Yes, the Engineering Services Coordinator can arrange to increase or decrease the size of your existing meter. In most cases, this is a relatively simple process. Again, the sooner this information is known, the less impact on completion of final service designs. If you have any further questions, please feel free to call the Engineering Services Coordinator at 925-688-8014.
No. EasyPay is currently only available for treated water customers.
Email EasyPay@ccwater.com with your account number and request to cancel or hold payment within 10 days of your statement date.
The Department of Homeland Security recommends that you store at least 1 gallon of water per person, per day and keep a three-day supply of water on hand. The American Red Cross also recommends one gallon of water per person per day, but with a two-week supply for every person in your household. For a family of four, that's 56 gallons of water.
Use clean containers of heavy, opaque plastic with screw-on caps. The American Red Cross suggests clean plastic soft drink bottles (it's very difficult to clean them), food-grade plastic containers or drums. Don't reuse plastic milk containers, since they are extremely difficult to clean completely and can contaminate your stored water. There are a number of commercial water storage containers available designed for storing drinking water.
You can also buy commercially bottled "spring" or "drinking" water and store it for up to a year.
You can safely store water for six months to a year, depending on how it is packaged.
If it's commercially-bottled "spring" or "drinking" water, the American Red Cross recommends you can keep it stored for a year as long as the container isn't opened. Once the container is opened, use the water immediately.
It's much less expensive to store tap water in your own containers, it's recommended you store tap water for six months maximum.
It's a good idea to label and date the water bottles or containers.
If you're using treated tap water, like CCWD tap water, and you do not need to purify the water before storing it in a clean container. You will not need to purify the water when you use it, if it's been stored for less than six months, again in a clean container.
The state of California has made it clear that water conservation rebates are not taxable. However, current federal IRS tax rules are not clear. The IRS has made it clear that CCWD is required to issue 1099 forms to individuals and companies that receive $600 or more in rebates in a calendar year. Therefore, CCWD now requires program participants that are approved to receive $600 or more in rebates in a calendar year to complete an IRS W-9 form and submit it to CCWD before receiving their rebate. Then in January of each year CCWD will issue 1099 forms to those customers that received $600 or more in rebates. Note, water agencies, state officials and members of Congress continue to work with federal tax officials to request that they treat water conservation rebates the same as they do the tax-free energy efficiency rebates. For more information, see Potential Federal Tax on Water Conservation Rebates.
1. The District needs to inspect participating properties to ensure the landscapes are not being converted back to lawns.2. Front lawns are less likely to be play areas for children and pets compared to backyards. Therefore, front yard conversions are less likely to convert back to lawns than backyard conversions.3. Front lawns can ‘advertise’ to neighbors to do the same, so they act as marketing for the program.
Note: Conservation programs are a way for CCWD to help provide water supply for the future. As such, CCWD wants to make sure the savings remain into the future.
Plants must be low water needing and adaptable to our local climate. Plants must be listed on the CCWD Approved Plant List (PDF). Plants not found on this list will be reviewed on a case-by-case basis.
The primary objectives of the Los Vaqueros Expansion Project Phase 2 are:
Here are directions
The original Los Vaqueros Dam was completed in 1998. At that time, the reservoir had a capacity of 100,000 acre-feet. In 2012, the dam was raised 34 feet, and is now 226 feet high (from toe to crest). It can currently store up to 160,000 acre-feet of water in the first phase of expansion. It is the largest reservoir in the Bay Area.
CCWD has a large list of environmental documentation available online, including the Draft Supplement to the Final EIS/EIR that was released in June 2017.
2019 – 2021 Finalize design, permitting, local agreements
January 2022 Final California Water Commission funding agreements
The watershed has two entrances. There is a north entrance on Walnut Boulevard near Brentwood and a south entrance off of Vasco Road near Livermore. See Directions to Los Vaqueros.
September 7 a.m. to 7 p.m.October 7 a.m. to 6 p.m.Nov. - Feb. 7 a.m. to 5 p.m.March 7 a.m. to 6 p.m.April-August 6 a.m. to 8 p.m.
Parking fees are $6 for the general public, $5 for seniors, and $4 for those who live in the Contra Costa Water District Service Area. See more detailed information about Fees.
There is a $6 per person daily permit fee for fishing. Entry booths to the watershed are staffed daily.In the event the booths are not staffed, visitors entitled to a discounted parking fee will need to pay at the Watershed Office in the North End near Brentwood, or the Marina.
No. Dogs and other pets are not allowed in the Los Vaqueros Watershed. This protects the multitude of small animals, some of which are endangered, that live in this protected watershed environment. Many of these endangered animals are easily disrupted by both the presence and scent of dogs. This rule also protects public safety and water quality. The Round Valley Regional Preserve, which borders Los Vaqueros, is also under this rule. At Morgan Territory, which is located above the Marina, dogs are allowed.
The weather is often very different from the surrounding areas, very hot and windy in the summer and very cold in the winter. View weather conditions or call the Marina at 925-371-2628.
Check out Recreation at the Los Vaqueros Watershed for the top 5 activities and upcoming events.
Barbecues are provided in the picnic areas, but no other barbecues are allowed. In summer months, be sure to check the fire warning levels. Very High, Extreme and Red Flag alert levels all prohibit barbecues.
No, there are no outside boats allowed on the reservoir. There are 16-foot and patio electric boat rentals available.
Call the Marina at 925-371-2628.
The program is conducted at the Los Vaqueros Interpretive Center on the north side of the watershed in Brentwood. Access the watershed through the north entrance at the end of Walnut Boulevard. The Interpretive Center is located at 19 Walnut Boulevard, Brentwood, the very end of Walnut Boulevard at the base of the dam.
Los Vaqueros Watershed Field Trips are available for 3rd and 4th grade students for public, private and home schools within our service area. Schools outside of our service area are not eligible for the program.
This program is popular and demand exceeds availability. Therefore, registration is handled through a lottery. The lottery is open every year during the month of August. To enter the lottery, you must submit a Los Vaqueros Field Trip Lottery Request Form. You will be notified if your form was selected in the lottery. Early in September, lottery results will be communicated via email, and booking trips will begin with successful schools.
Once the lottery is finished and you are notified that you will get a trip(s), you will receive an email with proposed dates. You can accept those or ask for other options. Los Vaqueros field trips happen on Mondays, Tuesdays, Thursdays and Fridays. You can notate your preference on the form, dates will be proposed based upon availability.
There will be plenty of time to schedule a bus for your trip(s). We ask that you confirm your trip(s) with us after you get confirmation of busing.
The lottery form asks how many programs you will need for the grade level at your school. Only one teacher per grade level per school needs to fill out a form.
The maximum number of students we can accommodate at a time is 40 without prior approval.
We require at least four adults (teachers included) in order to conduct the program, with a maximum of 12. Younger siblings are not permitted.
Prior to your field trip, teachers will receive a packet containing a letter describing the program and outlining how to prepare your class. You will also receive Los Vaqueros Journals for all students. Students should complete the pre-trip activities in the journal prior to the field trip. The journals are also used the day of the program; teachers need to bring the journals with their class to the watershed.
We do not cancel programs due to rain. If it is raining severely, the outdoor portion will be replaced with an indoor activity. If it is only misting or raining lightly, we still conduct the outdoor portion. Be sure to dress for the weather. Umbrellas are discouraged for safety reasons.
No, the field trip is provided at no cost to schools within the service area.
No, it is the school’s responsibility to provide transportation. However, we do need to know if you will be arriving by private automobiles or bus. CCWD will reimburse the school for the cost of bus transportation up to $300 per field trip. If you arrive by car, you will not be able to visit the top of the dam and reservoir; however, you will learn about the dam from a vantage point.
Typically, the valves are open for about three or four minutes, though the amount of time can be longer depending on the length and size of the pipe.
A walk-in service (WI) is only for a single 1-inch water service from an existing water main. There is a fixed cost for the installation of a standard 1-inch water service line, plus the cost of a 5/8-inch, 3/4-inch, or 1-inch meter. District crews always install these.
Facility Reserve Charges (FRC) are a “connection fee” to the District’s water system. Simply explained, any time a new water meter is installed, more demand is placed upon the overall water distribution system. The FRC fulfills two purposes. First, the fee recovers the costs that existing customers have paid to provide capacity for new customers through existing facilities. Second, the fee provides that future facilities built in order to serve new connections are paid for by the new connections. The FRC is a mechanism through which growth pays for the facilities needed to serve growth. The FRC is a fee imposed on new development wishing to connect to the District’s system as well as existing customers that upsize their reserved capacity in the system. The FRC is designed to equitably recover a proportionate share of available capacity in the existing water system and for the cost to expand system capacity necessary to meet the demands of future development.
Walk-in services have a fixed cost for installation and require one payment, including the Facility Reserve Charge (FRC) payment at the time of application, to initiate design, and install the project.
Black particles can come from three common sources: a broken water filter, a degrading faucet washer or gasket, or a disintegrating black rubber flexible supply line hose (for a water heater, washing machine, or kitchen faucet, etc.).
Brown or orange particles are typically rust particles that have broken off the inside of your water pipes or District water mains. These particles are very hard, irregular in size and shape, and can be several different colors (including black). They consist of mostly iron and are not a health hazard but they are a nuisance if they clog washing machine screens, shower heads, or faucet aerators. If the water with particles in it is clear, the problem is most likely from your piping. If the water is discolored for a few hours it is more likely from our water main.
Amber or translucent small round beads/resin. Defective screens in ion exchange water softeners can release resin beads that look like small balls in the water. The beads will be uniform in size and are the size of fish eggs. The resin can be brown, orange, or translucent and can sometimes be mistaken for sand. Call your service agent for repairs.
White or tan/sand-like particles that settle in the water usually come from internal plumbing. This material is pipe scale and is a combination of calcium carbonate and magnesium carbonate. Calcium and magnesium carbonates are naturally occurring minerals and are not a health hazard. Over time, these minerals can deposit on the inside of your pipes and then begin to flake off.
There are three common conditions that can cause scale to flake off pipes more rapidly:
Pipe scale can clog washing machine screens, shower heads, and faucet aerators. There is no practical way to remove pipe scale from the inside of your pipes. If the problem is severe, you may want to consider replumbing.
White or tan/sand-like particles in hot water. The water heater is another source for white or tan particles. As the water is heated, calcium and magnesium carbonates precipitate out of the water, forming white or tan sand-like deposits. As you use the hot water, these minerals can be carried along clogging washing machine screens, shower heads, and faucet aerators. To keep mineral deposits from accumulating in the water heater, flush your water heater at least once a year. Flushing regularly also extends the life of the heater and makes it operate more fuel efficiently.White particles in hot water that float. Floating white particles can be caused by the disintegration of the dip tube in your water heater. The plastic dip tube, directs the cold incoming water to the bottom of the tank. As the tube gets old, it can disintegrate, sending white particles into the hot water. These particles can be found in faucet screens and sinks or basins where screens are not installed. These particles are brittle and vary in size from small irregular pebbles to longer shards. Contact the manufacturer or vendor for advice on how best to repair the water heater.White or tan small round beads/resin. Defective screens in ion exchange water softeners can release resin beads that look like small balls in the water. The beads will be uniform in size and are the size of fish eggs. The resin can be brown, orange, or translucent and can sometimes be mistaken for sand. Call your service agent for repairs.
Crystals or residue left behind on fixtures, white surfaces, and pots after water evaporates are calcium and magnesium carbonates. These are naturally occurring minerals and do not pose a health hazard. These deposits may appear green, blue, or brown, having been colored by tiny amounts of the metals found in your water pipes. Carbonate deposits can be dissolved with white vinegar. Dishwasher deposits can be minimized by using a commercial conditioner, by using liquid detergents and by using the air-dry instead of the power-dry setting on your dishwasher, which bakes the carbonates onto glassware.
If you recently moved to the service area, your new water may taste different to you. Just as various brands of bottled water taste different due to the varying minerals they contain, the taste of domestic drinking water also varies with its source(s). Be assured that the drinking water that we provide meets or surpasses all State and Federal drinking water standards.
It is important to determine if the odor exists in the public water supply, premise plumbing, environment (potential drain odor).
If your plumbing is the source of the odor, you can try to flush the plumbing system or you can consult a licensed plumber. Contact CCWD at (925) 688-8156 if you suspect the water supply.Test for Odors
When you detect an odor in your tap water, we recommend that you perform what we call a glass test at the faucet.
Chlorinous, Bleachy, Chemical or Medicinal Taste/OdorThere are two common causes for a chlorinous, bleachy, chemical, or medicinal taste or odor in the water.
If the problem is the water supply, it will occur at every faucet and will not go away after a few minutes of running the water. An easy way to get rid of the chlorine taste and smell is to let water sit in a glass for a few minutes. Then, put the water in a covered container and chill it in the refrigerator. Cold water tastes and smells better than water at room temperature.
Although the total chlorine level is a fraction of what is found in pools and spas, you may occasionally detect the smell of chlorine in your water. This odor may be particularly strong in the shower since chlorine is released to the air more rapidly when mixed with hot water.
Foul, Sulfurous, Rotten Egg, and Sewage Odor
The most common cause of this type of problem is the drain. Over time, organic matter (such as hair, soap, and food waste) can accumulate on the walls of the drain and cause bacteria to grow on these organic deposits. To make sure the problem is not in the tap water, fill a glass with a small amount of tap water, then step away from the sink and swirl the water around inside the glass. If the problem is in the drain, the tap water in the glass should not have an odor.
These odors may be caused by an algae bloom. On occasion, mainly during periods of warm weather, CCWD can experience unusually large algal blooms in our source water, some consumers may experience some unpleasant taste and/or odor associated with their drinking water - musty, dirty or "earthy". Some important information and tips to know:
If you smell gasoline or an organic solvent odor in the cold water, call us immediately at (925) 688-8156 for further assistance. This problem is rare and potentially serious. Do not use the water. It is possible that your meter box was exposed to a hazardous substance.
We offer tours at two water treatment plants; one in Central Contra Costa County and the other in East Contra Costa County. The Bollman facility is located at 2015 Bates Road, Concord, and the Randall-Bold facility is located at 3760 Neroly Road, Oakley. Please indicate on the Water Treatment Plant Tour Request Form which facility you would like to visit.
Water Treatment Plant Tours are available for 5th grade students in public, private and home schools within our service area. Schools outside of our service area are not eligible for the program.
This program is popular and demand exceeds availability. Therefore, registration is handled through a lottery. The lottery is open every year during the month of August. To enter the lottery, you must submit a Water Treatment Plant Tour Lottery Request Form. You will be notified if your school was selected in the lottery. Early in September, lottery results will be communicated via email, and booking trips will begin soon after.
Water treatment plant tours are booked primarily on Wednesdays. Leave a comment on the form if you want one on another day of the week. We will make every attempt to accommodate.
Once the lottery is finished and you are notified that you will get a trip(s), you will receive an email with proposed dates. You can accept those or ask for other options. Water treatment plant tours happen mostly on Wednesdays. Tours are 90 minutes long and occur in the morning. You can notate preferences in terms of days of the week or months of the year on the form; however, dates will be proposed based upon availability.
The request form asks how many tours you will need for the grade level at your school. Only one teacher per grade level per school needs to fill out a form.
Most of our Water Treatment Plant tours are scheduled on Wednesdays during the normal school year. Two tours can be scheduled in a day: the 1st tour is conducted 8:40-10:10 a.m. and the 2nd tour is 10:30 a.m. to noon. This will usually allow one bus to shuttle the two classes.
The Water Treatment Plant Tours through are designed for 5th grade students.
The maximum number of students we can accommodate at a time is 40.
We must have at least three adults (teachers included) in order to conduct the program, with a maximum of eight. Younger siblings are not permitted.
