  2. With spring and summer comes construction season and a continuation of Platte Canyon’s efforts to repair, rehabilitate and replace portions of the District’s water distribution and wastewater collection systems. Platte Canyon plans to kick off two major capital improvement projects this summer and expects work on these projects to continue through fall.


    South Chase Way Water Main Replacement


    This project proposes replacement of 1,560 feet of 6-inch cast iron pipe with 1,560 feet of 6-inch C-900, class 150, PVC pipe in the Columbine Knolls Subdivision at South Chase Way between West Rowland Place and South Sheridan Court. The existing pipeline was installed in 1968 and has experienced three electrolysis caused failures. A number of pipelines in the general vicinity of this proposed replacement had also experienced electrolysis failures and have already been replaced. The Board of Directors awarded a Professional Engineering and Design contract to ENS Consulting, Inc. for this project which is budgeted at $398,012.


    Columbine Heights Sewer Interceptor Rehabilitation


    During the past year, District operations staff have conducted a comprehensive condition assessment of all 8-inch through 12-inch concrete sewer pipe in the District and have determined that all of the pipe is experiencing corrosion caused by hydrogen sulfide gas deterioration of the concrete. All 17,826 feet of concrete pipe has been inspected and prioritized for rehabilitation throughout a six year period beginning this year and ending in 2019.


    The first segments to be rehabilitated using a cured-in-place lining process are located in the Columbine Heights Subdivision at Robincrest Lane and Meadowlark Lane north of West Coal Mine Avenue. Project CIP 14-1S calls for lining 1,814 feet of 8-inch and 625 feet of 12-inch concrete pipe which was originally installed in 1958. This project also encompasses reestablishment of 17 service connections and lining nine concrete and brick manholes. The Board of Directors awarded a Professional Engineering and Design contract to Jacobs Engineering for this project which is budgeted at $112,200.
