Background/Discussion
The 30th Avenue sewer is located just south of I-80\I-29 from Indian Creek to South 11th Street. The existing sanitary sewer is a 36-inch diameter collector sewer that flows to the 29th Avenue Sanitary Sewer Pump Station. The sewer was constructed in the late 1960’s and is in need of rehabilitation. The majority of the sewer is VCP with a short segment of cast iron pipe. The sewer also runs under Indian Creek. This collector sewer serves a large area from Veterans Memorial Highway to I-80\29 and from Indian Creek to South Expressway including the Manawa Power Center. The method of rehabilitation will be Cured-in-Place Lining (CIPP). This is a no dig process where a liner is pulled through the pipe.
The existing sewer in 25th Avenue from 7th Street to 11th Street is a 24-inch diameter sanitary sewer with segments constructed mostly of reinforced concrete pipe with some clay pipe. The sewer was constructed in the 1950’s and is in poor condition. During recent investigations of reported lateral issues, it was discovered that the reinforced concrete pipe is severely deteriorated within this segment. The method of rehabilitation will be Cured-in-Place Lining (CIPP). There will be spot repairs on 25th Avenue to facilitate the CIPP process.
These projects are being combined because they are similar in scope and both will use a no dig process for pipe rehabilitation. One bid will be received for both projects. Costs for each project will be tracked separately.
These projects are included in the FY23 CIP with a preliminary budget of $750,000 for Project #PW23-08 and $450,000 for Project #PW23-14. Both projects will be funded with sewer funds.
