During the week of March 28, 2016, the Portland Water Bureau will conduct a test of flow meters located in the underground reservoir piping at Powell Butte Nature Park in Southeast Portland.
The half-day test will consist of Water Bureau operating engineers slowly draining approximately two-thousand gallons of de-chlorinated water from the reservoirs, to a discharge pipe, through the flow meters, and then into Johnson Creek.
The test will confirm the meters are accurately measuring water flowing through the pipe and can monitor future discharges.
Water Bureau representatives will be onsite at Powell Butte throughout the entire duration of the test to supervise the operation.
The flowrate, temperature, turbidity, and PH of all water discharged to Johnson Creek will be closely monitored to ensure compliance with all applicable environmental and regulatory requirements.
For questions about the operation, please contact Lindsay Wochnick, Public Information, at 503-823-3028 or by e-mail.
