The Tabb Pressure Reducing Station and Offline Storage Facility will construct one 2.5-million-gallon offline storage tank and a pressure reducing pump station.  The facility is designed to relieve pressures to the sanitary sewer system during wet weather events and provide flow balancing for HRSD’s James River and York River Treatment Plants. The flow balancing is necessary to support the process needs of the Sustainable Water Initiative for Tomorrow (SWIFT) facility. For more information about SWIFT, please visit swiftva.com. 

During wet weather events, the above-ground storage tank will temporarily hold the wastewater and rain/groundwater to relieve pressures to the sewer system. HRSD needs a storage tank in this area of York County to meet regulatory requirements. This location within HRSD’s sewer system offers significant benefits to York County and the region due to its universal (unmatched) connectivity within the HRSD pipe network. There is no other location within the HRSD system that allows for such a facility to manage system-wide flows from one singular location. 

No. While the offline storage facility is being designed and built to handle increased flow during routine wet weather events, its primary role is not intended to collect or treat stormwater. The tank is not sized to prevent all sanitary sewer overflows (SSOs) when named storm events (tropical depressions, tropical storms, hurricanes, etc.) or lengthy nor’easters occur. HRSD’s sanitary sewer treatment system operates separately from York County’s stormwater collection and treatment system. Additionally, site and related stormwater impacts due to this project will be managed onsite and will not impact offsite drainage systems.

HRSD’s mission is to protect the environment and that extends to all our construction projects. Aligned with our mission, this project will follow all related environmental regulations and evaluate opportunities during the design process to minimize impacts to the extent feasible. To achieve this mission, each project is reviewed for all potential environmental impacts and their associated permitting requirements. Specific elements that are under consideration for this project include: wetlands, protected species, and historic resources. During construction, erosion and sediment control measures will be installed, maintained, and regularly inspected to prevent degradation of sensitive resources.

The proposed facility is very safe, with over 10,000 similar tanks constructed over the last 70 years.  The tank will be monitored and controlled remotely to observe levels within it and to make sure that it is functioning as designed. HRSD will perform routine internal inspections of the tank to verify it's condition, and maintenance will be scheduled based upon these inspections.

The storage tank will not create odor issues. HRSD will install an odor collection and abatement system to treat the air in the tanks. Similar technologies have been proven effective with other HRSD pump stations, wastewater treatment plants, and other odor related facilities. The effluent (outgoing) air from the system will be monitored at all times, and an alarm will be sent to HRSD on-call staff in the event of odorous air detection.

HRSD, the design team, and the selected contractor will be coordinating closely with York County to minimize impacts on traffic and pedestrians in areas near construction. County noise ordinances will be followed by identifying and dampening excessive noise-generating activities as well as vibration from equipment during construction activities.

Work will typically take place Monday through Friday during daylight hours (7 a.m. - 5 p.m.). However, there may be times when extended hours, work at night, or weekend work may be necessary. 

Your water service should not be affected by this project.

Equipment and materials for this project will be stored on the project site within HRSD property boundaries and should not require any additional offsite storage.

Construction workers will park on the project site within HRSD property boundaries. Construction personnel will not be allowed to park their personal vehicles on the public streets.

HRSD operations staff will visit the station three to four days per week to ensure proper facility operation and perform routine maintenance. Monthly and annual preventative maintenance activities will be scheduled for the entire facility and will include additional maintenance activities beyond the day-to-day operations. These additional activities will include running the facility generator for approximately two hours. All regularly scheduled maintenance will occur during our normal operating hours. Exercising the generator on a monthly basis will be scheduled after 8am.  There may be times when operations staff is at the facility outside our normal operating hours to take care of unforeseen issues, but these situations should be minimal.

The estimated cost for the project is approximately $33.5 million and is financed by the wastewater treatment fees paid by HRSD customers.
