Covington Water District and Seattle University partner up for their second year

CEE Student team site visit to test water quality
December 15, 2017

Covington, WA, December 15, 2017 - Covington Water District (District) and Seattle University (SU) partner up for the second year of conducting real world project work with Seattle University engineering students. The District views this partnership with SU’s engineering students as a “win-win” for all involved.


The District initiated the Sugarloaf Well Corrosion Control Facility Preliminary Design Project in response to changing pH in its Well 3, which is the source for an individual satellite system that provides water to a single subdivision, that the District owns and operates. The new development in this system has caused water demands to nearly double as compared to previous years. The District’s water quality studies from 2014 to 2017 show that the pH of the water pumped from Well 3 dropped from 7.7 to 6.9. A lower pH correlates to higher corrosion of copper (and sometimes lead) in service lines and home plumbing and could increase dissolved copper and lead levels in the water. The SU Civil Engineering Team has been tasked to work with Kennedy/Jenks Consultants (K/J) to review historical data, carry out a feasibility analysis to determine the preferred solution to mitigate low pH and the potential for elevated copper concentrations, and produce a 30% preliminary design for implementing the preferred method. The project deliverables will be completed by Spring 2018.



The District provides water service to approximately 50,000 residential, commercial, industrial and irrigation customers throughout its 55 square mile radius service area. The District has twelve production wells, four treatment plants, emergency interties with two neighboring agencies, 20.6 million gallons of storage tanks and approximately 310 miles of pipeline. The District employs 38 women and men who work hard to keep water clean and running 24 hours, 7 days a week.  For more information, contact Tom Keown at 253.631.0565.
