• Average water use for the month June was 7.55 million gallons per day(mgd). This
usage is typical for this time of year, but slightly lower than our 10-year averages and last
year's usage. There was an unusual peak day of 10.22 mgd that occurred on June 25 with

an unseasonable temperature of 101 degrees reported. Current weather patterns for the
month of July seem to be closer to average.
• For the month of June, there was no change in Aquifer Storage Recovery (ASR)
conditions. Stored water for ASR well no. 1 is approximately 53 days of supply based on
1,000 gallons per minute (gpm) recovery rates. ASR well no. 2 has 81 days of supply
based on 1,500 gpm recovery rates.
• Data taken on July 11 at the Bonita Pump Station indicates a pH of 7.85 with 1.05 mg/L
chlorine residual, 26 mg/L alkalinity, and water temperature of 20 centigrade (68 degrees
F).
• Council was updated last month on Water Independence Day, water quality data, and
upcoming agenda items for the next fiscal year, including completion of the water master
plan update and water system development charge (SDC) methodology update.
• Staff still reports one to three calls per week regarding water quality at various locations.
These calls mostly relate to strong chlorine smell. Staff generally conducts water flushing
at these locations with improvement in water quality reported.
• Ozone is fully functional and operating without any problems reported by Lake Oswego
Tigard Water Treatment Plant staff.
5. Shared Personnel Agreement with Lake Oswego
Mr. Goodrich reported on an agreement with the City of Lake Oswego regarding shared
personnel, or employees. Some highlights were:
• Each of the cities—Tigard and Lake Oswego—have employees who are doing
basically the same thing. Through combined efforts it may be that certain personnel
with expertise can be shared to benefit both cities and reduce some costs.
• One of the best ways to share information of the two systems is to have employees
that are working together day in and day out, bringing not only their expertise but
also their tribal knowledge of how their respective system works.
• Two areas that are being considered for shared personnel are water quality and water
conservation. Another area that may also be considered is backflow.
The agreement will be brought to council for approval at a future business meeting.
6. Informational Items

7. Non-Agenda Items
