Project Summary

The Milford Water Utilities Department received a new NPDES Discharge Permit in 2020 that included low levels for total phosphorous, aluminum and copper. The existing WWTF would not meet the new limits without upgrades to the treatment process.

Hoyle Tanner was selected through a qualification-based process to perform a facility study and treatment pilot study that identified treatment alternatives, a recommended alternative, and provided opinions of cost for design, bidding, and construction of the improvements.

Hoyle Tanner’s team prepared public outreach materials, conducted meetings with water utilities commissioners, conducted the tertiary treatment pilot study, presented the findings of the pilot study to Milford Water Utilities and NHDES staff, organized WWTF tours for Milford operations staff to visit New England facilities using the pilot processes, and reported on the recommended alternative for the upgrade.
