152nd Ave Reservoir Project

Clackamas River Water (CRW) is underway with plans to implement an eight-year, $40 million capital improvement plan known as the "Backbone Projects". These improvements will greatly enhance overall water quality and distribution, increase system pumping efficiencies and improve provision of water for fire emergencies. The project will connect the CRW treatment plant and northern distribution system to our south service area customers via a new reservoir at 152nd Avenue, water transmission mains, and pump stations. All of these investments will be made possible through municipal bonding.

One element of the Backbone Projects program will be to construct a new 6 million gallon, partially buried concrete reservoir and associated improvements at the District's 152nd Avenue Reservoir site, located west of 152nd Avenue and Louise Lane, just north of Highway 212/224. The finished reservoir will be mostly buried so that only the concrete roof and upper wall section is visible at ground level for minimal site distance impacts.


Constructing a new reservoir at 152nd Avenue will:

  • allow for improved storage and water distribution within CRW’s service area along Highway 212;
  • create redundant storage for our north service area that allows us to inspect, maintain, and repair our Mather Reservoir;
  • expand storage for distributing water to our south service area (across Carver Bridge); and
  • improve our ability to supply water purchased by our neighboring water provider, Sunrise Water Authority.

Construction Activities

General On-Site Construction Hours will be between 7 a.m. and 5 p.m, Monday through Friday.

Truck & Site Access will be between 8:30 a.m. and 4:30 p.m.

The project will require major earthwork activities during construction and will produce daytime noise and dust. The reservoir site will be fenced off from unauthorized access.

There may be delays on local roadways; however, most construction activity will be limited to the reservoir site after initial excavation and final grading activities. Flaggers will direct traffic around construction related equipment. Design and construction efforts will be made to minimize impacts as much as possible.

All project construction activities will comply with requirements of the applicable governing jurisdiction, including permitting, traffic control, noise and dust abatement, hours of work, and other elements.
