Dear Valued Customer,
Beginning July 13 through mid- to late August 2026, Tualatin Valley Water District (TVWD), your drinking water provider, will be working with a contractor to conduct pre-construction field investigations near your neighborhood.
Crews will be working at the following locations:
- TVWD properties at 18755 and 18888 SW Kemmer Road
- SW Kemmer Road between the roundabout at SW 175th Avenue and SW 190th Avenue
Please see the map below showing the work areas.
Why is this work happening?
Before the project can be designed, engineers need accurate information about existing underground utilities, soil conditions, and site characteristics. The information collected during these field investigations will help create a safer, more efficient design, reduce construction risks, and minimize future impacts to the community.
During these field investigations, you may see crews performing the following activities:
- Utility locates: Crews will identify and mark underground water, gas, electric, communication, and sewer lines. Locating existing utilities helps protect critical infrastructure, improves worker safety, and reduces the risk of service interruptions during future construction.
- Exploratory drilling: Small drill rigs will collect soil samples so engineers can evaluate ground conditions and design safe, reliable foundations for the new facilities.
- Geophysical surveys: Crews will use specialized equipment to gather information about underground conditions without extensive digging, helping refine the project design while minimizing unnecessary excavation.
What to Expect
- No action is needed from you.
- Your water service will not be interrupted.
- Crews will not enter private property.
- There will be no digging or utility markings on your property.
- Work will take place only on TVWD property and within the public right-of-way along SW Kemmer Road.
- Access to nearby homes and driveways will be maintained.
- Traffic control will be in place on SW Kemmer Road. Please follow posted signs and directions from flaggers.
- Work will take place on weekdays between 7 a.m. and 6 p.m.
- You may see temporary paint markings, flags, or stakes used to identify underground utilities and property boundaries.
- Small test holes may be dug in the public right-of-way to locate utilities and verify soil conditions. These holes will be temporarily patched with asphalt the same day.
- Vehicles and equipment will be staged at TVWD's Kemmer Road properties.
If you live near the project area, this early field work is expected to have only minor, temporary impacts. TVWD will continue to keep you informed as the project moves forward and will provide advance notice before construction begins in 2027.
What’s Next?
When construction begins, the project is expected to include:
18755 SW Kemmer Road
- Building a new replacement pump station with a backup power generator
- Constructing a new 2-million-gallon concrete water reservoir
- Installing underground waterlines connecting the new facilities to existing reservoirs and the surrounding water system
- Building a new stormwater detention facility
- Installing new fencing and landscaping
18888 SW Kemmer Road
- Demolishing and removing the existing pump station after the new facilities are operational
Before construction begins, TVWD will provide additional information, including:
- Planned construction schedules
- Any expected water service impacts
- Information to help you prepare for upcoming work
Why These Improvements Matter
The project will help provide safe and reliable water service for years to come by:
- Improving the reliability of the water system
- Strengthening the system during emergencies, including earthquakes and severe weather
- Replacing aging infrastructure with modern, resilient facilities
- Supporting reliable water pressure for firefighting throughout the area
