The Village of Huntley municipal wastewater collection, conveyance and treatment system was first installed in the late 1940’s. The original wastewater treatment plant (WWTP) was located east of Route 47, just south of the existing Main and Bakley Streets intersection. The sanitary sewer system has continued to broaden as areas within the Village have developed. The increase in flows required the original WWTP, currently named the East WWTP, to expand several times. Its current Design Average Flow (DAF) capacity is 1.8 million gallons per day (MGD). As the Village’s planning boundaries continued to expand and the build out of the East WWTP property was in sight, the Village planned for a second WWTP. The West WWTP was originally constructed in 1999. It is located west of Route 47 near the southwest corner of the intersection of Main Street and Kreutzer Roads, and its current DAF capacity is 2.6 MGD. Currently, the Village’s sanitary sewer network consists of 13 Lift Stations and 162 miles of sanitary sewer conveyance pipes ranging in size from 8” to 36”. Village staff utilizes a Supervisory Control and Data Acquisition System to monitor the mechanical treatment components of the Wastewater System.
A Comprehensive Master Utility Plan was completed in 2015 and updated in 2022. The goal of the Plan is to provide planning to maintain sustainable cost-efficient Water Works and Wastewater Systems for current and projected water uses. The Village identified required regulatory and operation & maintenance (O&M) upgrades to both the East and West Wastewater Treatment Plants consistent with the recommendations of the 2015 Comprehensive Master Utility Plan. The construction of the regulatory upgrades was completed in 2018. Targeted O&M improvements have been identified in the 2022 Plan Update and construction continues on an annual basis as funding is available.
The National Pollutant Discharge Elimination System (NPDES) Permits for the East and West WWTP's requires the Village to establish and update three planning documents collectively referred to as Wastewater System Regulatory Planning Documents as follows:
Phosphorus Discharge Optimization Plan
Phosphorus Removal Feasibility Study
Capacity, Management, Operations and Maintenance (CMOM) Plan
The Wastewater System Regulatory Planning Documents provide the Village with a comprehensive plan for optimizing the total phosphorus removal at the WWTP’s and provide a targeted approach for the CMOM plan as required by regulators.
