City to build 3 million gallon facility off Bull Mountain Road to help meet water demands from River Terrace

Tigard is moving forward with plans to design and build a new 3 million gallon reservoir and new water lines and to replace a temporary pumping station.

Earlier this month, Tigard city council awarded a $ 2.1 million contract to Emery & Sons to build what’s known as Reservoir 18 and an accompanying pumping station.

“Tigard must plan and build capital improvements to serve our growing community,” said Rob Murchison, deputy director of public works for Tigard, in a press release. “This business will add essential components to our complex water distribution system, which will allow city professionals to deliver clean drinking water from the water intake facility located on the Clackamas River to homes. and businesses in the Tigard water service area. ”

The city will build the new reservoir at one of two sites west of Tigard in the Bull Mountain Road area. One is in Sunrise Park, north of the intersection of Southwest 150th Avenue and Sunrise Lane. The other is the Cach Water site, located on the west side of Block 15100 of Southwest Sunrise Lane.

A new pumping station will be built, allowing the city to move water more quickly from the 410 foot elevations to homeowners in the 560 foot elevation zone.

The city’s website says the new reservoir is needed to meet the demand for water in the River Terrace subdivision.

Throughout the month, Murraysmith, the city’s design engineering firm, and contractors will visit potential sites both for initial survey work and to conduct geotechnical surveys to determine which site will perform best. .

According to city officials, the project will be built in two phases known as the progressive design-build process. The process allows both the city and the designer-builder to work together and come up with a guaranteed maximum construction price.

Construction will likely begin in spring 2022 and end in spring 2024.

The cost of the project is split almost equally between the city’s water fund and the city’s water system development charge fund.

An estimated 60,000 residents receive water from the Tigard water utility area, including those in King City, Durham, two-thirds of the City of Tigard and the unincorporated area of ​​Bull Mountain. The other residents of Tigard receive water from the Tualatin Valley hydraulic district.
