In 2008, the cities of Lake Oswego and Tigard formally endorsed a partnership agreement for sharing drinking water resources and costs. Under the current agreement, the City of Lake Oswego is the managing agency responsible for the permitting, design, construction and operation of the new facilities. An Oversight Committee, made up of two elected officials from each city, also acts an advisory group that provides oversight on project issues.
The Portland Water Bureau recently detected the presence of Cryptosporidium, a potential pathogenic microorganism, in several samples collected at their Bull Run intake in January and February.
Although our water systems are close to Portland’s, the City of Lake Oswego and Tigard Water Service Area customers receive their drinking water from a different source and the treatment process is also different than Portland’s. Lake Oswego and Tigard Water Service Area’s primary water source is the Clackamas River. The recently upgraded filtration system at our water treatment plant removes Cryptosporidium and pathogens that may be detected in the Clackamas River water supply. Ozone, a powerful oxidant, also provides an additional treatment barrier to protect public health.

Crane delivery and removal
On the morning of Tuesday, January 31, a very large (360-ton) crane will be delivered to the site using several large semi-trailer trucks. Due to site constraints, and to minimize traffic impacts during delivery, trucks will be staged near the I-5. Only one truck will enter the site on Carman Drive at a time, unload crane materials and then exit, before another truck then arrives to the site. Five trucks are expected to deliver parts for the crane.
