Kelly Butte Reservoir Goes Online, Now Serving Customers

Add a Comment

In March 2015, the two cells composing the new 25-million gallon underground reservoir at Kelly Butte in southeast Portland were successfully placed online. The reservoir now serves Bull Run water to customers across the City of Portland and beyond.

By the NumbersThe Portland Water Bureau and Hoffman Construction Company crews began work on the project in late 2012 with demolition of the 43-year-old, 10-million gallon above ground steel tank.

Close to a year of excavation on the butte followed with the removal of about 180,000 cubic yards of rock and soil to make way for the new underground tank two-and-a-half times the old tank's size. 

Beginning in the fall of 2013, more than 2,000 truckloads of concrete were brought onsite, pouring the reservoir’s floor.

By summer 2014, the reservoir’s wall, roof, and support columns were completed.

The underground reservoir has now disappeared from view completely, being covered with onsite earthwork.

Also constructed onsite is a stormwater detention basin, an overflow detention basin, multiple vaults, and valve structures.

Work at the site will continue through 2015 with construction of access roads, fencing, landscaping and the strategic planting of more than 1,660 trees and 7,250 shrubs across the entire site. The total project cost was estimated at $90 million and is currently projected to finish under this budget.

The Kelly Butte Reservoir will serve Portland's east side and be a stopover to supply water to the Washington Park reservoir and southwest Portland area water storage tanks.

Reminder: Yearly Testing for Single-Family Home Backflow Assemblies Starts Now!

Add a Comment

Single-Family Backflow Single-Family Backflow

Does your home have a lawn and garden irrigation system?

These irrigation systems have a backflow assembly that is located between the drinking water supply and irrigation system. Backflow assemblies allow water to enter your irrigation system while at the same time preventing water that is in your irrigation system from flowing back into the drinking water supply. Once a year homeowners are required to test the backflow assemblies connected to their system. Backflow assemblies are essential in keeping you, your family, and Portland’s drinking water safe.

Why do I have to test my backflow assembly every year?
Testing is required every year by the State of Oregon Health Authority to ensure that your assembly is functioning properly. Every year in April, the Portland Water Bureau sends reminder letters to single-family homes to test their backflow assemblies. The perfect time to test is between April and June since this is after freezing weather has passed, which can damage your backflow assembly, and before the heavy watering season begins.

Who can test my backflow assembly?
Homeowners need to hire a private company to test their backflow assembly. The Oregon Health Authority provides a list of state certified backflow assembly testers on their website. Some of these companies specialize in specifically testing backflow assemblies, and some are landscape companies that provide that service. Either type of company can perform the testing you need. The market is fairly competitive, so homeowners can expect to pay between $25 and $45 per test.

What happens during a test?
The tester will test your assemblies and record the assembly serial number and test results. Your tester may or may not use stickers that the Portland Water Bureau provides as a courtesy with your reminder letter. If they don’t use them, your test is still valid, and you may just discard the stickers. When finished, the tester will then give you a copy of the report, keep a copy for themselves, and send a copy to the Portland Water Bureau. When the Portland Water Bureau Backflow Records department receives the test report, your account is updated with the results and is marked as up-to-date.

Annual testing is necessary to let the State and Portland Water Bureau know that your backflow assembly is in compliance every year, and assures you that you are keeping your family’s drinking water safe.

Questions about your backflow assembly or backflow assembly testing?
