Lessons On Non-Potable Water For WWTPs

The Wastewater Treatment Plant of the City of Steamboat Springs, Colorado, needed a solution to reduce solids in the non-potable water (NPW). The plant’s superintendent for over 20 years, Gilbert Anderson explained that in Steamboat Springs, treated effluent from a secondary wastewater treatment plant is stored in an open pond and is then used for plant water i.e. non-potable water (NPW).

Anderson said that, “previously, solenoids that control water flow for wash water on the bar screen would become inoperable due to solids in the NPW.” The filters they had added to keep solids out of the solenoids required frequent filter replacement and were costing the facility money and excessive labor.
