• Average water use for the month of March was 3.95 million gallons per day
(mgd). This usage is typical for this time of year, but lower than our 10-year averages,
and the same as last year at this time. This may be due to unusually colder
temperatures compared to last year.
• Stored water in the aquifer storage and recover well no. 1 (ASR-1) includes
approximately 53 days of supply based on 1,000 gallons per minute (gpm) recovery
rates. ASR-2 has 81 days of supply based on 1,500 gpm recovery rates.
• One water quality complaint has been received regarding chlorine taste. Field staff
flushed a dead-end line to improve water quality; the customer did report
improvement.
• Small portions of ozone have been added to the water at the treatment plant.
In response to a question from Commissioner Henschel,Mr. Goodrich reported that
there was no damage at any of the city's water properties due to the April 7 windstorm.
5. Water Quality Update
Mr. Goodrich reported on water quality and construction activities for the Lake Oswego-
Tigard Water Project. The following are some highlights of the report:
• Ozone installation construction is complete. The water treatment staff are learning
the system through training for ozone, and the plant has been conducting functional
tests over the last week. Staff anticipates functional testing to be completed soon,
with full operational capabilities by the beginning of May.
• Additional construction activities include Waluga Reservoir no. 1 (WR-1) roof
concrete pours are complete (delayed due to weather). Contractor crews are
beginning to strip the forms. The final wash down, disinfection/chlorination and
fill/leak test is planned for late April. Staff anticipates completion in mid-May (which
is two weeks behind schedule due to cold and wet weather delays with roof structure
concrete pours).
• At the water treatment plant: besides ozone commissioning, there is a lot of civil
work occurring at the site–forming site walls, curbs, driveway aprons, stone walls,
`good neighbor' cedar fencing, and catch basins for stormwater management.
Pervious pavers are being placed and work on the pedestrian pathway (that will
eventually be open to the public) will start soon. Landscape irrigation is in the very
early stages. Paving will be weather dependent, but it is anticipated to get started over
the next month. Construction trailers will be removed in the coming weeks. Project
staff expect completion will be in early June.
• The project completion celebration date is yet to be determined—our
communications outreach staff are still expecting it to be sometime in mid-July.
Possibly in late June a separate "thank you" ribbon cutting ceremony for the
neighbors will take place. Outreach information will be shared with I" members as
it becomes available.

• Additionally, our staff are involved in a Clackamas River history video produced with
the Clackamas River Water Providers, along with a water treatment process video
featuring the Lake Oswego-Tigard Water Treatment Plant. Both are being produced
to celebrate national drinking water week (May 8 through May 13).
