Water Treatment Plant Replacement Project

Replacing 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 6 months. 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. However, built in 1931, it does not meet current building codes and seismic requirements. The walls are crumbling and the structures are no longer sound.

In the event of an earthquake, it is highly likely the plant would be damaged and would no longer be able to treat and supply safe drinking water. Several specialized engineering firms the City has contracted with to assess the plant have agreed on this point.

The facility is beyond a simple repair.
