Lucas Creek Pump Station Upgrade PR_JR010600
System: James RiverType: Pump Stations
Driver Category: I&I Abatement-Rehabilitation PlanProject Status: Design DelayRegulatory: Rehab Plan Phase Two
This project will upgrade all equipment at Lucas Creek Pump Station, to include but not limited to: pumps, motors, controls, and electrical service. Lucas Creek must be able to pump independently as a lift station and as a pressure reducing station in multiple flow directions. Work should also include the rehabilitation of the wet well.Scope of work to include the replacement of all yard piping, and an addition of two flow meters and vaults. Approximately 132 feet of 30 and 36-inch pipe is also to be replaced.
PROJECT JUSTIFICATION
This project is required in order to provide expanded operational flexibility in the North Shore system. The new Kiln Creek Interceptor Force Main (IFM) and Route 171IFM in conjunction with upgrades to Lucas Creek will reduce system pressures during wet weather events.
FUNDING TYPE CONTACTS

This project involves the installation of approximately 3,600 linear feet of 30-inch force main (FM) from the Colony Area Interceptor Force Main (IFM) and the Oyster Point IFM to Patrick Henry Pump Station.
PROJECT JUSTIFICATION
The installation of this FM would provide much needed operational flexibility to the North Shore system in moving flows between the James River and York River systems while simultaneously reducing system pressures. A Conditional Flow Acceptance Letter was issued to the City of Newport News in September 2009 specifically referencing the proposed FM improvements. The proposed FM improvements will provide a significant reduction in system pressure for Oyster Point IFM located in Jefferson Avenue. The City of Newport News has experienced several failures of FMs that connect directly to the Oyster Point FM over the past few years. A HART Analysis of the City Center Study Area was completed in October 2010 and included the proposed force main. Several scenarios were included in the study and resulted in a recommended FM size of 30-inches. The recommended 30-inch FM sizing will provide the capacity and ability to reduce system pressures as well as provide flexibility to convey flows under various conditions.
This project will replace approximately 7,000 LF of 12-inch, 14-inch and 16-inch HRSD force main (FM) (NF-020 and NF-021) from the intersection of Route 171 (Oyster Point Road) and Jefferson Avenue to the proposed Patrick Henry jumper. The proposed force main sizing (30-inch) was performed during the City Center HART Analysis.
PROJECT JUSTIFICATION
Preliminary hydraulic and capacity analysis show that pressures in the HRSD FM are hindering the City of Newport News' pump stations from entering the HRSD system during high flow conditions. Future development is planned for the service area, which will exacerbate the current problem. This FM segment will also provide additional capacity and system flexibility when combined with other proposed improvements.
This project will involve the installation of approximately 2,250 LF of new 36-inch force main (FM) from the intersection of Alpine Street and Huxley Place to the MiddleGround-City Center Interconnect FM west of the CSX railroad tracks. This extension will allow for abandonment of the 36-inch reinforced concrete pipe (RCP) from theintersection of Maxwell Lane and Route 60 to the intersection of Huxley Place and Carnegie Drive (approx. 5,500 LF abandoned).
PROJECT JUSTIFICATION
This FM extension will connect to the Middle Ground Blvd FM that will allow for the abandonment described above. An evaluation of the existing record drawings indicated the presence of 6 unvented high points in the section to be abandoned. Based on this finding, it is likely that the interior of this pipe is suffering from severe crown corrosion. Considering the age of this pipe (> 40 years), the length of the projected bubbles, the location of adjacent city pump stations, and available repair techniques (particularly on the flat bottom RCP) the solution for the conditional issues here is complete abandonment.
This project involves replacing and rerouting approximately 850 LF of 12-inch Asbestos Cement (AC) Pipe with 16-inch pipe from Morrison Pump Station (PS) to the connection point at the main trunk across the CSX railroad. The project will also include temporary bypass pumps to provide additional pumping capacity at the station.
PROJECT JUSTIFICATION
The 12-inch Asbestos Cement interconnect force main is designed to divert flows from the 12-inch Cast Iron force main to the 20-inch Asbestos Cement force main. Existing debris build up completely prevents flow through the pipe segment. There were several unsuccessful attempts to flush the pipe segment. The option to send flow from the Morrison PS to the James River Treatment Plant through the 20-inch AC pipe is critical in case of a break on the 12-inch Cast Iron pipe installed in 1967. The Morrison PS also has significant capacity issues. This replacement will improve capacity at this location.

This project involves the replacement of approximately 5,800 linear feet of Ductile Iron (DI) pipe from just north of the intersection of Thorncliff Drive and Warwick Boulevard to a location 900 feet west of the intersection of Warwick Boulevard and Lucas Creek Road, along Lucas Creek Road.
PROJECT JUSTIFICATION
In 2014, two failures occurred on the Lucas Creek-Woodhaven Interceptor Force Main (NF-015) just south of Woodhaven Road within a 6 month period. These failures shared the same characteristics as the previous failures on the PCCP force main in 2007 that required replacement of approximately 2 miles of HRSD force main. After the first failure (April 2014), several Broadband Electromagnetic (BEM) scans and Ultrasonic Thickness (UST) tests were performed along the force main from Woodhaven Road to Lucas Creek Road along Warwick Boulevard. The BEM and UST testing confirmed a loss of wall thickness along the bottom third of the pipe. pH sampling along NF-008 and NF-015 resulted in values ranging from 4.4-6.1. These failures required the southbound lanes of Warwick Boulevard to be closed in order to facilitate the repair. The road closure required an extensive detour resulting in significant traffic congestion and delays for motorists within the northern portions of Newport News. Due to the condition of the pipe immediately downstream of the repairs, a Prompt Repair Work Order has been issued for the replacement of approximately 1,200 LF of pipe from Woodhaven Road to the intersection of Thorncliff Drive. Currently, the Pepsi Plant is meeting the established pH level at their discharge/sampling point. However, as the flow is conveyed through the gravity, pump station and force main system of the City of Newport News and HRSD, the pH and composition of the discharge changes. As seen in pH sampling along NF-008 and NF-015, between the Pepsi Plant and Lucas Creek Road, the values range from 4.4 – 6.1. HRSD's P3 Division is currently monitoring and analyzing the plant discharge for possible changes in the established level.
This project involves the replacement of approximately 8,000 linear feet of Ductile Iron (DI) pipe from the intersection of Warwick Boulevard and Lucas Creek Road to the Lucas Creek Pump Station (PS).

While no condition assessment has been performed along this section of force main from Warwick Boulevard and Lucas Creek Road to the Lucas Creek PS, it is anticipated that a loss of wall thickness has occurred along the bottom of the pipe. Additional condition assessment activities may be performed based on actual pipe condition obtained from the Prompt Repair work and the work to complete Phase I.
