Program History
The City of Billings Water and Sanitary Sewer Replacement Projects were initiated in 1979 as part of an overall strategy to keep the City’s water distribution system and sanitary sewer collection system in the best possible overall condition.With only a few exceptions, the City has replaced water and sewer mains each year since 1979.

Indicators of Replacement Needs
A number of indicators are utilized to identify areas of the system needing replacement and generally include:
  • System capacity analyses
  • Water main break history
  • Sanitary sewer back-up complaints
  • Sanitary sewer root intrusion maintenance activity
  • Sanitary sewer video analysis
  • Public Works Department street improvement projects
Generally, the replacement projects scheduled in any given year are first prioritized based on coordination with plans the Engineering Division has to improve City streets. City resources are best utilized and the public best served when marginal water and sanitary sewer systems in streets scheduled for improvement are replaced along with the street improvements; this way, newer streets are not cut for utility replacement long into the foreseeable future.

Secondly, an attempt is made to concentrate water and sewer replacement projects in a limited number of geographical areas each projectyear.By replacing systems in only a few areas each construction season, the City does not burden it’s customers in that area with construction-related inconveniences for multiple years within a reasonable time span.Also, the City is able to obtain more competitive bid prices on the work performed if the projects are not scattered throughout the City.

The Distribution and Collection Division prioritizes portions of the system for replacement on a rolling five year schedule; this schedule must remain flexible and project priorities change frequently based on changing public needs from year to year. The amount of work actually performed each year is based on available budget.Recent annual project budgets have been on the order of about $3.5 million each for water and sanitary sewer replacement.In the last five years, the lineal footage of water and sewer replacements have been on the order of 7,500 to 12,500 feet each for water and sewer.
