South 208th Street AC Main Replacement

This project will replace approximately 1,100 feet of 4 inch asbestos concrete pipe and approximately 7,550 feet of 6' asbestos concrete pipe in South 208th Street from 107th Ave SE to 96th Ave SE and some associated lines southwest of 108th Ave SE & South 208th Street. The pipes were installed in the late 1950's and 1960's and have reached the end of their useful life. We have had several breaks in the area and have determined that the pipe is soft and needs to be replaced. Currently the 6" pipe on South 208th street is shown in our Comprehensive Plan to be increased to 12" and most of the associated lines would increase to 8" for better fire flow.

We are in the design process and hope to start construction towards the end of 2008.

Westview Terrace Main Replacement

The Westview Terrace AC replacement project replaced approximately 8725 feet of 4 inch and 6 inch asbestos concrete watermain with 4 inch and 8 inch ductile iron pipe. Additionally 10 fire hydrants, 144 water service lines and all existing valves installed between 1959 and 1964 will be replaced. This project was located between SE 208th and SE 216th, west of 100th Ave SE and east of 96th Ave S.

This project began construction in July 2007 and was completed this spring. King County is planning to overlay the roads in 2008 which should save money for our ratepayers.

Lake Desire Watermain Replacement and Low Pressure Sewer Installations

This project is scheduled to begin construction in the June of 2008. The 6" and 8"asbestos concrete water main around the lake was installed in 1965; it will be replaced with 8" ductile iron pipe, new water service lines, valves and fire hydrants.

Along with this replacement, the District will be installing a low pressure grinder pump system to convey sewage to an existing gravity sewer system. Upon completion of this work the roads around the lake will be overlaid.

SE 187th AC Watermain Replacement

This project involves replacement of 850 feet of 4" asbestos concrete water main built in 1962 with 8" ductile iron pipe. The project is located on SE 187th Pl, just west of 102nd Ave SE. We will also loop the system with an additional 600 feet of 8" ductile iron pipe connecting to an existing main off of SE 189th St. New water service lines, valves and fire hydrants will also be installed which will add better water quality, fire flow and reliability to the system.

This project is scheduled for construction in the summer of 2008.

Tank 5 Re-Coating

We have just completed the re coating of our 4,000,000 gallon water tank located at 125th Ave SE & SE 211th St. this fall. This included stripping the coatings on the inside, making minor repairs, and rebuilding the chlorine injection piping along with the installation of a new ladder system on the outside and re coating with a design similar to our tank at 11423 SE 188th St.
