Aberdeen Water Reclamation Facility Plan from Banner Associates, Inc.
The City of Aberdeen is a rapidly growing community. According to U.S. Census Bureau, Aberdeen's population has been increasing steadily since 2000, reaching a 2020 population of 28,495. In addition to residential and commercial growth, Aberdeen has also seen substantial industrial growth. Current industrial wastewater flow averages approximately 930,000 gallons per day and is expected to increase in the coming years. All of this has led to a lack of treatment facility capacity, leading to necessary facility improvements.
The Aberdeen Water Reclamation Facility (WRF) has been upgraded since completion of construction in 1983. The last set of major improvements focused on activated sludge nitrification facilities and equipment replacement which began in 2005 and were completed in 2009. In addition, various minor improvements have continued since 2008. While much of the facility equipment varies in age from 12 to 16 years old, the Aberdeen WRF is in desperate need of additional capacity. The timing of the capacity expansion also provides justification to prepare for anticipated stricter effluent limits and increase facility resiliency through added redundancy.
In this Facility Plan, design flows were determined, capacity issues identified, and expansion alternatives have been identified and evaluated. The results of these analyses led to improvements in nearly every building and process at the WRF. Improvements to the Aberdeen WRF generally consist of the following:
- Main lift station improvements
- Headworks expansion and equipment improvements
- Primary clarification expansion
- Intermediate pumping improvements
- Biofilter process demolition
- Activated sludge and final clarification expansion
- UV disinfection expansion
- Biosolids thickening and stabilization improvements
- Biosolids handling improvements
- Administration building improvements
- Miscellaneous site, electrical, and mechanical improvements
The purpose of the Facility Plan is to address capacity improvements, ongoing residential, commercial, and industrial growth, facility age and condition, prepare for anticipated stricter effluent limits and increase facility resiliency through added redundancy.
