Description


UPDATE: 

  • Pre-Planning Work July 13 - Mid/Late August 2026: TVWD will be working with a contractor to conduct pre-construction field investigations at TVWD properties at 18755 and 18888 SW Kemmer Road and on SW Kemmer Road between the roundabout at SW 175th Avenue and SW 190th Avenue. No action is needed from nearby residents or businesses. Information gathered will help design the future Cooper Mountain Pump Station and Reservoir 3 Project, which is slated for construction in fall 2027. Learn more.

Project Overview

TVWD will conduct a project to strengthen and improve the portion of the water system serving the Cooper Mountain area. 

Work will occur at two TVWD properties: 

18755 SW Kemmer Road

  • Build a new replacement pump station, including the installation of a new backup power generator.
  • Construct a new, concrete, 2-million-gallon reservoir.
  • Install buried waterlines to connect the two existing reservoirs at 18888 SW Kemmer Road to the new reservoir, pump station, and offsite water system piping.
  • Install a new stormwater detention facility.
  • Fence and landscape the property.

18888 SW Kemmer Road

  • Demolish and remove the existing pump station.

Project Benefits

TVWD is building a new pump station and reservoir at Cooper Mountain to replace aging infrastructure and better serve the community. Benefits include:

  • Improving Reliability: Upgrading the pump station and connecting it to multiple reservoirs means customers are less likely to experience water outages.
  • Strengthening the Water System: Having backups and multiple ways to move water makes the entire system more resilient.
  • Preparing for Future Emergencies: The improved system can keep water flowing during emergencies, including earthquakes and extreme weather.
  • Modernizing Infrastructure for Long-Term Use: Replacing an aging pump station and outdated piping ensures the system can serve current and future customers safely for decades.
  • Improving Fire Protection Support: A stronger and more stable water system helps maintain the water pressure needed for firefighting throughout the area.
