Kemmer Road Intertie Project

What did TVWD complete?

To increase the efficiency, reliability, and resiliency of water service to the Cooper Mountain area, TVWD completed installation of approximately 1,550 feet of 24-inch ductile iron transmission water main between TVWD's Cooper Mountain Reservoirs and the City of Beaverton's Cooper Mountain Reservoirs on SW Kemmer Road. 

This project will now:

• Provide TVWD customers and City of Beaverton residents with an emergency connection between the two water systems.
• Allow for the decommissioning and replacement of the current primary pump stations and reservoirs that push water from the valley floor to the summit of Cooper Mountain for TVWD. Those facilities are at the end of the expected service life and scheduled for replacement.   

TVWD is not planning construction or other maintenance for the existing two Cooper Mountain reservoirs at this time.

The water system connection partnership project was a $1.5 million investment in the water system serving this area, paid using funds from regular water bills.

Timeline

Construction began in February 2024 and was completed in May 2024.  

Key milestones of this project include the: 

• Installation of the new water main under the westbound traffic lane of SW Kemmer Road,
• Connection of the water systems between TVWD and the City of Beaverton,
• Thorough testing and preparation of the water main for use, and
• Restoration of the curb, sidewalk, and westbound traffic lane of SW Kemmer Road. 

How did this affect customers?

Construction Impacts for Neighbors

TVWD worked with K&E Excavation to complete this project under the supervision of TVWD's Construction Inspectors. 

Installation of water mains required open trench excavation to install the new water pipeline under the roadway. This generated some noise, dust, and vibration in and around the project area during working hours.  

Construction work hours were permitted from 8 a.m. to 5 p.m., Monday through Friday. Construction within the roadway was limited to 8:30 a.m. to 4 p.m., Monday through Friday. 

Temporary road surfaces were maintained during construction so vehicle traffic could drive over the completed areas immediately. Once the new piping was installed, tested, and in service, final road paving in the areas dug for construction was scheduled. 

Traffic Impacts

The majority of new water transmission piping was installed under the westbound lane of Kemmer Road, on the north side of the roadway. Limited areas of construction and installation crossed both travel lanes on Kemmer Road where the new water piping connected to each reservoir at the ends of the project area. 

Traffic was controlled by flagging in the active construction area. Flagging traveled with the active construction area on Kemmer Road as the project progressed. 

Equipment Storage & Staging

TVWD's contractor, K&E Excavation, stored equipment and staging project materials near the project area to reduce the movement of large vehicles and equipment. Materials and equipment were stored at the vacant TVWD property neighboring the Cooper Mountain Reservoirs on Kemmer Road.
