postcard regarding the availability of the Water Quality Report was mailed to every
household in Tigard.
6. Water quality Update
Mr. Goodrich gave the following updates on water quality and construction activities for
the Lake Oswego-Tigard Water Project (LOTWP):
• Recent water quality reports from testing of the new source water and treatment
process indicate that TTHM, HAA5, and lead risks are greatly reduced. These are
direct benefits to consumers and customers regarding public health, and reducing the
risks associated with disinfection by-products and lead exposure due to drinking
water in household plumbing.
• As reported last month, the ozone installation construction is completed. The water
treatment plant has also completed functional tests. Ozone addition is now on line
serving both communities. Staff has seen a reduction in water quality complaints, and
most customers queried during other interaction have stated that the water tastes
good.
• Some minor punch list items for the project at the water treatment plant are wrapping
up. Project staff anticipate that final completion will meet the June 30 deadline.
• The celebration date for the project completion is Thursday, August 31, at the
LOTWTP. IWB members are invited to attend. More information will be sent out to
members in the next month.
• Water Independence Day was June 9 for customers in the Tigard water service area.
Staff will be providing a water system update to the City of Tigard Council on June
20.
7. Lake Oswego Tigard Water Partnership Project
Mr. Goodrich provided the board with a copy of a slide presentation that council will be
shown at a future meeting. This handout is on file in the IWB meeting record. The
presentation, Tigard Water Service Area Supply System Update, highlights the benefits of
ownership in a regional water supply system.
In response to an inquiry by Commissioner Henschel regarding the maintenance of fire
hydrants, Mr. Goodrich explained that the property owner is responsible for keeping the
hydrant visible within the public right of way. Fire hydrants are under the ownership of
the water provider so the city will generally work with the property owner and repaint
hydrants if necessary.
