Water Treatment Plant Replacement Project

Water Treatment PlantReplacing our aging Water Treatment Plant is the City Council's number 1 goal for the second year in a row.

Council has hired Stantec Engineering Inc. to facilitate this process and assist in the many decisions that need to be made before construction can begin.

The current goal is to have a new Water Treatment Plant online and producing high quality drinking water by winter of 2023.

Stantec will present to Council on a monthly basis for the next six months, starting February 2019. They will provide information and details on the types of plants that can be constructed, size required for today and the future, location, and advanced construction options.

Why Does the Plant Need to be replaced?

The Water Treatment Plant has faithfully served the Grants Pass residents over the last 87 years. Turn on a tap and out comes an unending supply of good, safe drinking water. The water currently produced by the Treatment Plant is of the highest quality.

However, ensuring reliable delivery of water to our community is becoming increasingly more challenging.


  • The plant is our only source for treating and supplying drinking water.
  • The plant does not meet current building codes.
  • The plant does not meet seismic requirements.
  • The plant would be unable to provide safe drinking water after an earthquake if it is damaged.
  • The plant walls are crumbling and the structures are no longer sound.
  • The plant is beyond a simple repair.
