This summer, the City's Mercerwood Drive Water System Improvement Project installed 1,163 feet of eight-inch ductile iron water main and associated water system components, such as fire hydrants.
The project replaced a four-inch asbestos cement water main beneath Mercerwood Drive, between Shoreclub Drive and East Mercer Way, which was undersized and had experienced breaks in the past. Mercerwood is one of the older neighborhoods on Mercer Island, and the four-inch pipe was aging and due for replacement.
After two months of design in early 2013, construction began in early June and was completed on July 12th, in time for the street paving project which began immediately thereafter.
The water improvements
were completed on time and within the $442,000 project budget. This
project provides an additional benefit for the surrounding area: a
segment of water main was installed to interconnect the Mercerwood Drive
system to the existing water main at East Mercer Way, improving water
quality and delivery for the neighborhood.
