Project Scope: Development of WWTP to support 150-bed substance abuse treatment center.
Location: 2 locations: Cecil County, MD
Recovery Centers of America contracted with RAUCH inc. to develop a 150 bed substance abuse center located in Cecil County MD, previously subdivided as Bracebridge Estates. The additional rooms and related support facilities associated with the new center will require the design, approval, and construction of a wastewater treatment facility. The WWTP will be designed with a capacity of up to 20,000 gallons per day that can treat the wastewater to the groundwater discharge permit standards anticipated for this project. Special emphasis was directed to reducing the concentrations of nitrogen and phosphorous associated with the groundwater disposal of the treated wastewater, in consideration of the State of Maryland’s current groundwater discharge permit limits for community wastewater treatment systems. RAUCH inc. has proposed a wastewater disposal alternative for the project. A small MBR WWTP is capable of not only meeting the referenced GWDP limits, but also ENR limits. MDE has issued point discharge permits from both public and private WWTPs that meet ENR standards. A point discharge is possible if there is an established TMDL for the project or the project can be developed with a net zero nitrogen and phosphorous discharge. This can be achieved through TMDL credits and trades from facilities with nitrogen and/or phosphorous credits. Regardless of the method of disposal, a small MBR WWTP is anticipated to be the most feasible option for the project. Phase 1 engineering will include services to investigate the feasibility of a point discharge for the project and will focus on the redevelopment of the existing manor house into an approximately 50 bed facility. Wastewater disposal for the entire project is planned for a community tile disposal field. RAUCH inc. will design the sewage reserve area for the phased construction of the tile field to support the phased development of the project. Phase 1 will also require the design of all related utilities for water and sewer service to both buildings. Phase 2 includes the development of a comprehensive 100 bed facility. The new facility will require the design of parking, grading, drainage, water and sewer service, sediment and erosion control, stormwater management.
