More than 45,000 hours of work later, we have made excellent progress on our current water treatment plant upgrade.
We began upgrades to the plant in May 2018 and renamed it shortly thereafter. The Mesa Water Treatment Plant, built in 1942, is now the Phillip H. Tollefson Water Treatment Plant on the Mesa, named for our former CEO and water visionary.
The progress our employees and contractors have made on the plant in the last nine months is incredible. Watch this timelapse video
to see nine months of hard work condensed into 12 seconds.
Last Thursday, CEO Aram Benyamin joined members of the Utilities Board and other employees on a tour of the plant to see construction progress.
This $30+ million dollar project will enhance the facility's performance and efficiency in treating drinking water for our community. It is expected to come online in 2020.
The scope of the overall project includes:
Reconfiguration of the solids drying beds
Construction of a new main pretreatment building
Construction of two small auxiliary buildings
Construction of a new raw water vault
Led by Jeff Daniel and Lisa Hagerman, the tour group saw the construction progress for the new polymer system, the new main pretreatment building and the new finished water vault. They also viewed 3D renderings of the designs for the new raw water vault and pretreatment basins. The solids drying beds are complete.
Did you know that our original pretreatment facilities were in use for more than 75 years prior to this upgrade? New indoor pretreatment facilities offer significant benefits including reduced chemical use and improved control and performance.
This plant upgrade is a good business decision. Tollefson Water Treatment Plant provides our lowest cost drinking water. A great team continues to work tirelessly to ensure good stewardship of this financial investment.
We do not embark on projects on this magnitude often. Utilities Board members showed enthusiasm and support for the project. They understand the overall benefit this provides to our community.
Fun fact: Over 45,000 hours of work have gone into this upgrade already, with a good safety record.
