Nansemond Treatment Plant SWIFT Improvements

"Nansemond Treatment Plant SWIFT Improvements"
Nansemond Treatment Plant Advanced Nutrient Reduction Improvements, Phase II (NP013820)
Nansemond SWIFT Facility (GN016380)

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):
The first step to producing SWIFT Water® is at the Nansemond Treatment Plant Advanced Nutrient Reduction Improvements (ANRI) project. This project will increase the wastewater treatment capacity to 50 million gallons per day (mgd) and provide a higher quality of wastewater. This additional capacity will accommodate the flow from the Boat Harbor Treatment Plant which is closing in 2025. The Boat Harbor Treatment Plant is being converted to a pump station, which will send flow to the Nansemond Treatment Plant. Once the treatment plant upgrades are completed, the final step in the project will be the construction of the Nansemond SWIFT Facility project.

SWIFT Facility:
The SWIFT facility will provide the improvements necessary to produce SWIFT Water® and deliver it to the recharge wells. From the Nansemond SWIFT Facility, HRSD intends to recharge the Potomac Aquifer with up to 34 million gallons a day (mgd) of SWIFT Water®.

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 swiftva.com.

Project Cost: $667,000,000

Construction for the Advanced Nutrient Reduction Improvements project is ongoing. All of the walls for the clarifiers have been poured. Construction of electrical duct banks continues for two of three new electrical buildings. Earthwork and work below ground level for three process buildings is ongoing. The base slabs for the Primary Effluent Equalization Tank and Aeration Tanks 8 and 9 are being formed and tied.

The procurement phase for the SWIFT facility is complete, and the Design-Builder has been selected. Preliminary design and planning meetings are underway.

The work will be confined to HRSD property; however, construction traffic will be entering and exiting the site on Armstead Road. Most traffic impacts will begin at College Drive and Interstate 664 heading northwest along College Drive to Armstead Road and then following Armstead Road all the way to the treatment plant. Comprehensive traffic control plans will be implemented to minimize inconvenience.

Advanced Nutrient Reduction Improvements - Construction:: Spring 2023 - Fall 2025

Nansemond SWIFT Facility - Design:: Summer 2024 – Summer 2025

Nansemond SWIFT Facility - Construction:: Fall 2025 - Spring 2029

This project will contribute to the broader Sustainable Water Initiative for Tomorrow (SWIFT) Program, which will add advanced water treatment processes, producing highly-treated water (SWIFT Water®) that meets drinking water standards and is suitable for recharge of the Potomac Aquifer. Once complete, the projects at the Nansemond Treatment Plant will improve the existing plant effluent in addition to producing up to 34 million gallons per day of SWIFT water.

This program will help reverse declining groundwater levels, reduce saltwater intrusion, slow or reduce land subsidence, and significantly reduce the amount of nutrients such as nitrogen and phosphorus entering the Chesapeake Bay, thereby helping to ensure HRSD’s ability to protect public health and the environment for decades to come.

Disruptions to traffic will be minimal, and in most cases, all lanes of traffic will be maintained. No detours are planned or anticipated, but flagging may be used to help direct traffic as needed. All aspects of the project work may be located within HRSD property. The only impacts to traffic will be due to construction equipment entering and leaving the Nansemond Treatment plant via College Drive, between Interstate 664 and Armstead Road, and Armstead Road from College Drive to the treatment plant.

Work will typically take place Monday through Friday during daylight hours (7 a.m. - 3 p.m.). However, there may be occasions when extended hours, work at night, or weekend work may be necessary.

There should not be any interruptions to the water or sewer service in the area.

The construction will not affect the existing pavement. All construction traffic will be permitted to travel on the public roadway.

Typical construction noises such as equipment engines, back-up alarms, materials being delivered, diesel generators, air compressors, sawing, and associated activities should be anticipated.

The contractor will have offices and tool storage facilities on site for the duration of construction. Equipment that is being installed as part of the work may be stored on the plant for short periods of time before it can be located in its permanent location. There will not be any materials or equipment stored in the public right-of way.

Construction workers will park in designated spaces within HRSD property. No personal or company vehicles will be permitted to park on public streets.

The estimated cost for the project is $667 million and is financed by the low interest loans from the U.S. Environmental Protection Agency and Virginia Clean Water Revolving Loan Funds and the wastewater treatment fees paid by HRSD customers.
