Among our CIPP ProjectsState Arizona Project Small Diameter Sanitary Sewer Rehabilitation Owner/Client City of Phoenix, Arizona, Water Services Department;
Details Over 135,000 total footage Challenges and solutions SAK Construction was brought in to use CIPP to rehabilitate nearly 50,000 linear feet of deteriorating sanitary sewer lines throughout the City of Phoenix. The pipes were 8 inches to 14 inches in diameter and ran under busy streets in residential and commercial areas. With CIPP, SAK was able to complete the rehabilitation process quickly and cost-effectively with minimal disruption to traffic and the above-ground environment. The success of this project—the first three initial job orders—generated six additional job orders of more than 85,000 linear feet of sewer lines.
Project Indian School Road Improvements Owner/Client SRP (Salt River Project), City of Scottsdale, Arizona; Achen-Gardner Location Scottsdale, Arizona Details Installing CIPP on a 24-inch diameter line Challenges and solutions As part of the Indian School Road Improvements project for owner Salt River Project, the water and power utility in Arizona, the contractor was widening the road and needed to work over the top of the pipeline. To prevent damage to the pipe from the additional weight, SAK was brought in to install CIPP on the line. California Project Los Coyotes Water Reclamation Plant Interceptor Sewer Rehabilitation Phase II Owner/Client County Sanitation Districts of Los Angeles, California Location Los Angeles County, California Details 10,425 linear feet, 54-inch diameter to 78-inch diameter pipe Challenges and solutions The $10.4 million Los Coyotes project involves repair to a major interceptor sewer stretching nearly two miles underneath busy residential and commercial areas in Los Angeles County. Rehabilitation work utilizes SAK’s CIPP process to minimize surface disruption. Work began in December 2009 with expected completion during the third quarter of 2010. Kansas Project 2007 Sanitary Sewer Improvements Owner/Client City of Osawatomie, Kansas; Bates Utility Co. Inc. Location Osawatomie, Kansas Details 51,000 linear feet total (SAK portion 37,242 linear feet). Challenges and solutions The City of Osawatomie, Kansas, needed to rehabilitate 51,000 linear feet of aging sanitary sewer lines and brought in Bates Utility Co. as general contractor. Bates Utility tapped SAK to handle the CIPP portion of this project. The CIPP involved pipes of 8 inches, 10 inches and 12 inches in diameter and more than 650 house connections. The Osawatomie sewer rehabilitation effort was SAK’s largest project at the time. The owner was so pleased with SAK’s completed work on this project that it asked to have SAK’s CIPP crew return and take on several additional pipeline segments that had originally been slated for pipe-bursting or open-cut rehabilitation. Kentucky Project Contract No. 4 Wastewater Collection System Rehabilitation Owner Paducah McCracken Joint Sewer Agency, Paducah, Kentucky Location Paducah, Kentucky Details 12,332 total footage Challenges and solutions The Paducah McCracken Joint Sewer Agency awarded a contract to SAK in 2008 to rehabilitate 12,332 linear feet of pipeline using CIPP. The pipes ranged in size from 6 inches to 12 inches in diameter. Among the most challenging aspects of the project was a difficult-to-access 10-inch VCP pipe located in an easement along a creek. The line was full of roots and had steel T-posts driven into the top of it. SAK’s CIPP crew successfully pulled the T-posts, cut the roots and lined the pipe without a single point repair.
Missouri Project Owner/Client City of Jefferson, Missouri Location Jefferson City, Missouri Details 32,043 total footage Challenges and solutions The Basin 17 project had numerous areas of difficult access as well as several large interceptors that need to remain in service during the rehabilitation process. To keep the sewers in service and prevent discharges, SAK used innovative methods to provide bypass pumping. The City of Jefferson subsequently awarded SAK their Basin 16 Rehabilitation contract to repair an additional 31,000 feet of sewer line.
State Missouri Project Owner City of Eldon, Missouri Challenges and solutions The City of Eldon was experiencing major inflow and infiltration problems as a result of the deterioration of sewer lines that were constructed between 1910 and 1920 of clay tile pipe and included joints every three or four feet. The sewer lines, which run under busy residential and commercial areas, had extensive root penetration. To avoid the cost and disruption to the community of digging up and replacing the lines with prefabricated PVC pipe, SAK was brought in to rehabilitate several sections of the line using cured-in-place pipe. Minnesota Project Biglow/Bush Sewer Rehabilitation and Euclid/Edgewater Sewer Lining Owner City of St. Paul, Minnesota Location St. Paul, Minnesota Details Rehabilitating 62,000 feet of sewer line Challenges and solutions SAK completed two sewer projects of over 30,000 feet each for the City of St. Paul. To rehabilitate the deteriorating pipes, which ranged in size from 8 inches to 27 inches in diameter, SAK used the CIPP process. The lines were spread throughout the city and ran underneath heavy traffic areas. With the CIPP approach, SAK minimized potential traffic disruption. Despite the addition of extra segments to the original project specifications, SAK finished both projects on time. A third project for the City has been awarded to SAK.
