District Agreements

  • Service Agreement (PDF) is used for projects that the District installs. These are typically smaller projects such as fire services, main extensions less than 100 feet or projects that involve taking service off existing mains. 
  • Water Main Extension Agreement (PDF) (WMEA) is used for projects that the developer installs. These are typically larger commercial or residential developments that involve installing additional mainline piping and multiple services.
  • Standard Easement Agreement (PDF) Easements are required any time the District installs facilities outside the public right of way. The easements must be granted using the standard easement agreement and submitted with a plat and legal description prepared by a licensed professional surveyor.
