HRSD, your regional wastewater treatment utility, is implementing the Sustainable Water Initiative for Tomorrow (SWIFT) Program by constructing the second SWIFT Facility at the Nansemond Treatment Plant to produce a highly-treated water (SWIFT Water®) that meets drinking water standards and is suitable for recharge of the Potomac Aquifer. This Program will help reverse declining groundwater levels, significantly reduce the amount of nutrients such as nitrogen and phosphorus entering the Chesapeake Bay, and may reduce saltwater intrusion and land subsidence, thereby helping to ensure HRSD’s ability to protect public health and the environment in alignment with HRSD’s Promise and Vision.

Advanced Nutrient Reduction Improvements (ANRI):
Construction for the Advanced Nutrient Reduction Improvements project is ongoing. The installation of conductors to all three new electrical buildings and new motor control centers continues. Rough-in of power and control raceways, wire pulling, and termination preparations continue for Primary Clarifier 5. Stress testing is continuing for Aeration Tank 6 with the newly installed design modifications. Primary gravity thickener mechanisms are being installed in both tanks.

SWIFT Facility:
The basin floors are being formed for the SWIFT Influent Pump Station and Recharge Well Backflush Equalization Tank. Pile driving for deep foundations for the SWIFT Facility site is ongoing and is expected to continue through May 2026. Pile driving hours will remain between 7:00 a.m. and 5:00 p.m., Monday through Friday, with Saturday pile driving hours being 8:00 a.m. to 4:00 p.m.  Preparation of the contractor's staging area, office complex, and access roads to the recharge wells on the SWIFT Facility site continues.  Installation of SWIFT Water supply and backflush lines for Recharge Wells 4, 5, 6, and 7 continues.  24-hour drilling will occur at Well 10 during the month of March; the drilling is not expected to cause any excess noise other than a hum from a generator. Stormwater improvements continue for Pond 1 and Pond 2.

Together, the overall goal of the Nansemond projects is to help support growth and protect future generations. To learn more about SWIFT or to schedule a tour of the SWIFT Research Center (located at HRSD’s Nansemond Treatment Plant in Suffolk, VA), please visit www.hrsd.com/swift/.

Project Cost: Approximately $952,000,000
