2019 Water & Sewer Rehab Projects
Schedule 1: North 27th Street West Water Main Replacement
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 of Billings Public Works Department 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 will start in February 2019 and the total construction time will be approximately 4 to 5 months. The project will be constructed by COP Construction. DOWL is the City's engineering consultant that prepared the design and will be overseeing construction. . Project updates will generally be provided on a weekly basis during construction by email and on the City’s website.
April 21, 2019 Update:
See the attached project exhibit for an overview of the upcoming work areas and general project status. Construction on North 27th Street during the week starting April 22 will continue between Poly Drive and Rimrock Road. Work will involve installing new water main and fire hydrants. The three west-most lanes of North 27th Street will continue to be closed in the vicinity of the work, resulting in one lane of traffic in each direction. Toward the end of the week, a separate water main crossing of North 27th Street just south of Rimrock Road will begin. Traffic control will change substantially during a portion of this work, resulting in traffic being shifted to the west side of North 27th Street. As always, all reasonable efforts will be made to minimize inconveniences to business access and to general traffic flow. Pressure testing and water quality testing of the new water mains will occur following each completed segment of pipeline installation, and then asphalt pavement restoration will follow.
Most water customers affected by this project will be placed on a temporary water system that will deliver City water during the time that construction is occurring adjacent to their building. Between 6th Avenue North and 9th Avenue North, the contractor is currently installing and testing a temporary water system to supply customers that have service lines supplied from the water main in North 27th Street. These commercial customers will not experience any interruption in water service, unless agreed upon in advance with the contractor for special circumstances. Buildings that are not connected to temporary water typically have service lines supplied along other adjacent streets and therefore will also not see an interruption in service. Water main replacement is expected to begin at 6th Avenue North on or around April 30 and proceed north along North 27th Street.
Thank you for your patience and consideration as the Contractor performs work in your area.
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.
