Thompson Reservoir Maintenance Project

TVWD is performing maintenance at its Thompson Reservoir. Construction is scheduled began in May and is expected to take 4-6 weeks to complete. The Thompson Reservoir capacity is 5 million gallons and was originally constructed in 1978.

What is TVWD doing?Thompson Reservoir

TVWD is hiring a contractor to remove and re-seal the reservoir's roof and replace the access hatch along with other site maintenance needs.

Maintaining this reservoir helps provide reliable water service into the future with optimal system flexibility for water storage and delivery.

Night Work Planned June 10-15

Contractors will be working overnight June 10-15 from 7 p.m. through 1 a.m. to seal the reservoir's roof. This work is estimated to need only three of the six nights, though we're planning a larger window to ensure favorable weather. Sealing the reservoir's roof requires cool evening temperatures and is very dependent on weather. 

During this time, neighbors can expect:

  • A smell similar to road paving
  • Minor noise from handheld power tools and low-level talking among crew members
  • Use of lights to brighten the area after dark, aimed directly towards work areas on the reservoir

This is one of the final steps of this project. We'll wrap up the project by installing safety railing and roof drains after the roof is coated and cured. These last items will be done during normal work hours.
