Williamsburg Treatment Plant

James City County offers much to area residents and visitors including opportunities to enjoy some of the best outdoor activities in the region.

Newport News City Center at Oyster Point is a business district thatfeatures retail shops, restaurants and offices as well as residential spacecentered around the fountain in the heart of the development.

Williamsburg Farmers Market, voted one of America's FavoriteMarkets, attracts residents and visitors alike to Merchants Square tobuy locally grown produce from local farmers.

York County Yorktown is most remembered as the site where BritishGeneral Lord Cornwallis surrendered to American and French forcesunder the command of General George Washington, bringing an endto the last major battle of the American Revolutionary War. But evenbefore the struggle for independence, the town was a bustling andprosperous 18th century seaport, having been established by the1691 Act of Ports. Yorktown also witnessed major Civil War activity.Its fortifications held off a Union army attack during the PeninsulaCampaign of 1862.

PROJECT DESCRIPTION

The project is to design and construct needed replacement of the treatment plant main switchgear, generator, generator switchgear, controls and appurtenances. The replacement of the switchgear will require the construction of a new switchgear building. The project also includes the replacement of three sub-stations (transformer, switch, distribution panel) and electrical provisions to accommodate the future SWIFT Facility.

PROJECT JUSTIFICATION

This project will replace 43 year old switchgear and transformers nearing the end of its useful life. The switchgear is starting to become unreliable, switchgear breakers have failed to open and experienced nuisance tripping, and many of the component parts are difficult to obtain. An independent engineering evaluation has concluded a new building is required to house the switchgear due to the limited available space in the existing building and the need to maintain plant operations during construction. The SWIFT project requires additional generator capacity thus making it appropriate to replace the generator at this time.

PROJECT DESCRIPTION

The project will upgrade the existing Lodge Road Pump Station (PS) including all station pumps, controls, pipe, valves, and electrical infrastructure.

PROJECT JUSTIFICATION

This project will address needed capacity improvements within York County in an area that has current wet weather capacity challenges and newly proposed additional development flows. Lodge Road PS requires pumping upgrades to provide additional capacity. These improvements will require an electrical service upgrade and will drive replacement of the pumps, electrical equipment, generator, and controls. Lodge Road PS receives flow from Rolling Hills PS, several York County Pump Stations, and a local collection system. During wet weather periods, the upstream collection system has experienced Sanitary Sewer Overflows (SSOs) related to pumping capacity. An interconnect was installed by North Shore Interceptors to allow Rolling Hills PS to discharge into the Lodge Road PS. The activation of the Route 199 Interim Pressure Reducing Station (PRS) along with the development projections in the service area require capacity enhancement due to increased flow and discharge pressure.

$2,664 $243 $1,453 $967 $0 $0 $0 $0 $0 $0 $0 $0

PROJECT DESCRIPTION

This project involves the rehabilitation of the Kingsmill Pump Station wet well and will require complete bypass of the pump station. Additionally, yard piping, interior and exterior/buried valves, and a portion of the interceptor force main upstream and downstream of the pump station will be replaced as part of this project.

PROJECT JUSTIFICATION

The existing wet well at the Kingsmill Pump Station is showing signs of significant deterioration, evident by the exposed aggregate documented during wet well inspections. The wet well is also not configured to easily allow for bypass pumping, as there is no slide gate or permanently-mounted suction line currently installed. Inthe dry well, pump suction valves have been showing signs of significant wear. Recently, one of these valves was replaced because it was determined to be inoperable. Outside the pump station, valves and force main piping need replacement. Three of the eight diversion/isolation valves are inoperable and another three valves are horizontally installed gate valves – valves that have proven to fail prematurely. The reinforced concrete force main in the area where the pump station connects is unnecessarily deep, adding safety risk and potential for delayed repairs in the event of a pipe failure. Since the early 1970's when this pipe was originally installed, 15 to 20 feet of fill has been placed on top of this line, adding a static load onto the pipeline that has already resulted in one failure.

PROJECT DESCRIPTION

This project is for the design and construction of improvements to the secondary treatment process at the Williamsburg Treatment Plant. Based on performance of thecurrent secondary treatment configuration and recent process modeling, the initial improvements will include installation of ammonia based aeration control, nitrate-based recycle flow control, equipment to release excess air, and all required appurtenances. This initial effort is intended to significantly delay, and may potentially eliminate, the need for design and construction of a supplemental carbon addition system, which was the basis for the original total project estimate.

PROJECT JUSTIFICATION

Advanced secondary treatment improvements, including nutrient reduction measures, will be required to provide stable source water quality that meets the influent requirements of the full scale SWIFT facility at Williamsburg Treatment Plant.

PROJECT JUSTIFICATION

This project will replace the 1960s toilets, sinks, showers and lockers and allow for more space in both the men's and women's restrooms; provide much needed office space for plant staff; refurbish the conference room; and create additional work shop space. This project will also provide for an operations control room in the hurricane category 2 rated administration building. The existing operations control room is in the incinerator building which must be abandoned during tropical storm force winds.
