Future Projects


Future Planning

The 2011 earthquake in Japan resulted in heightened awareness of potential damage from a large earthquake off the Oregon Coast.  In response to increased concern, the Water Board is investigating methods of improving the resiliency of water storage and distribution infrastructure.  A significant step forward will be a seismic analysis of both the Upper Pony Creek Dam in the summer of 2015 and Merritt Dam in the spring of 2016.

The Water Board began increasing the replacement rate of galvanized iron water mains in January of 2008.  These mains are generally 2-inch diameter.  Most were installed in the 1950's, and internal and external corrosion of the mains causes reduced available service flow and frequent main breaks.  Since 2008, Water Board crews have completed twenty projects replacing 7,600 feet of galvanized iron water main.

Five other projects planned during the next several months include replacement of 2-inch diameter galvanized iron main on Minnesota Avenue, 7th Avenue, North 11th, and Barham Terrace in Coos Bay, and Isabelle Avenue in North Bend.


Liquid Poly Aluminum Chlorohydrate (ACH) Solution Tank Replacement

The Pony Creek Treatment Plant uses ACH as a coagulant to clump particulate matter together in water in the coagulation and flocculation processes. These processes aid the sedimentation process or the process that settles out particulates in the water.  This chemical is used in our water treatment process 365 days a year.

The current tank has a capacity of 9,000 gallons and is 26 years old.  The tank is showing its age and has a very small contained leak. This tank will be replaced and relocated this summer with 2 smaller Polyethylene tanks with a combined capacity of approximately 7,000 gallons.
