The water and sewer system is constructed as a network of interconnected main lines; usually in a grid pattern; following the general layout of city right-of-ways. Water mains are dependent upon a series of loops; this configuration efficiently provides nearly constant pressure and uninterrupted flow. The sewer mains are connected in a manner that maximizes potential for gravity flow and minimizes reliance upon lift stations. The mains and connections are constructed at least to a minimum standards prescribed by the state of Montana. After construction, approval and acceptance of the mains, right-of-way and right-of-way easements are dedicated to the city.

Each developer of property, that requires municipal water or sewer must construct a piping system that fully serves their property and extends the piping throughout the development in a manner that provides both an extension of the piping network and the potential for further extension of the network.

Frequently a project is not immediately adjacent to existing water or sewer mains. In these situations the developer must extend the mains through areas owned by others who may not wish to participate in the construction of such mains.

The developer is entitled to enter into an agreement with the city that may recover an equitable portion of the cost of extending mains though areas that are without such service and an equitable portion of the cost of constructing mains of a size larger than the minimum required by state standard when larger than required to serve his development.

This chapter provides the method of assessment for such recovery of costs. (Ord. 655 § 1(part), 2004)
