Water Treatment Plant Construction

Water Treatment Plant Expansion Project

Project Background

The Ames water utility was formed in 1891.  The existing Water Treatment Plant (WTP) was constructed in 1927 as a two million gallon per day (MGD) iron removal facility.  Numerous improvements and expansions over the years have expanded the treatment to include lime-softening and brought the current capacity to 12 MGD.

After extensive evaluation, it was determined that the cost to renovate, modernize, and expand the existing facility would exceed the cost of constructing a new treatment plant facility.  On July 14, 2009, the Ames City Council directed City staff to proceed with planning and design for a new water treatment plant at 1800 E. 13th Street.

Design was complete in the Spring of 2014.  The project was awarded to Knutson Construction for $52,497,000.  The project will be funded in large part through a low-interest loan from the Iowa Drinking Water State Revolving Fund (SRF).  Repayment of the loan will be made from utility revenues.  A series of rate increases were put into place to account for the loan repayment and those increases are completed. 

Construction started November 2014 and is expected to be completed in Spring 2017.
