2018 Water & Sewer Rehab Projects

Schedule 1:  North 27th Street West Water Main Replacement

Project Overview:

The 'North 27th Street Water Main Replacement Project' includes the replacement of over 5,000 feet of water mains on North 27th Street between 6th Avenue North and Rimrock Road.  The current 16-inch cast iron water line, originally installed in 1945, has deteriorated with age and experiences frequent breaks.  This project will replace the pipeline along with all valves and hydrants along the corridor.  This project will allow the City to better serve their water customers, reduce annual system maintenance costs, convey water more efficiently to other areas of the water distribution system, and sustain a safe and reliable infrastructure.  Construction is expected to start in November 2018, weather permitting, with most of the work to be completed in the spring and early summer of 2019 after a winter shutdown.  The total construction time will be approximately 4 months.  The project will be constructed by COP Construction, who was selected through a competitive bid process.  DOWL is the City's engineering consultant that prepared the design and will be overseeing construction.

Pre-Construction Update:

Construction on this project is scheduled to begin (weather permitting) after the completion of MDT's Zimmerman Trail reconstruction project, due to the complete closure of Zimmerman Trail this summer and early fall.  Just prior to construction, a more specific start date will announced and project updates will generally be provided on a weekly basis thereafter.  See the accompanying project exhibit for an overview of the upcoming work areas.  This exhibit will also be updated throughout the project duration to indicate construction progress.

Construction for this project will involve trenching to install the new water main.  Most of the work will be confined to the southbound (west-most) travel lanes and the center turn lane.  New hydrants will be installed at the edge of the right-of-way, typically just behind the sidewalk.  Once construction begins, traffic on North 27th Street will be reduced to one lane in each direction in the immediate vicinity of the work.  This project will result in side street closures adjacent to North 27th Street at various times.  Business access and hospital emergency access along the project corridor will be maintained throughout the project duration.  All reasonable efforts will be made to minimize inconveniences to businesses and to general traffic flow.  Water users affected by this project will be placed on a temporary water system and will see no changes to water service.

See the attached exhibit for an overview of the upcoming work areas and general project status. 

Schedule 2

November 12 - November 16 Update:

See the attached “Weekly Update” maps for an overview of the active work areas and general project status for Zone A and Zone B.  

Zone A

Work this week will consist of the contractor performing general cleanup and surface restoration preparation.  A subcontractor will continue prepping and pouring concrete approaches.  The subcontractor will pour one side of the alley approach at a time to allow for continuous access into the alley from at least one direction.  A second subcontractor will continue prepping and paving of alleys (which were previously asphalt) and streets.  In addition to alley closures, traffic control will consist of local street closures around the construction area.  Access for area residents and businesses will be maintained throughout the project duration.        
Zone B

Construction and restoration of Zone B has been completed.                              



Thank you for your patience and consideration as the Contractor performs work in your area.

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 analysis
  • 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 project year.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.
