PROJECT DESCRIPTION

This project is to rehabilitate and/or replace a portion of SF-066 Norview-Estabrook Division I 18-Inch Force Main. The project extents are approximately 900 LF of 18-inch force main that stretches between Cromwell Drive and Robin Hood Road along Chesapeake Boulevard. This is a companion project to the section of Force Main SF-066 to be replaced as part of the City of Norfolk Fairmount Park Neighborhood Improvements Phase 14.

PROJECT JUSTIFICATION

The pipe material and age are similar to other portions of the interceptor system in which HRSD has experienced multiple failures due to the tendency of cast iron to lose integrity with age. Construction activity for the new City lines also presents a significant risk to HRSD pipe lead joints, which are very sensitive to vibration. HART analysis has been completed for this system.

PROJECT DESCRIPTION

This project is to design and construct a replacement pump station for the 1951 Ferebee Pump Station.

PROJECT JUSTIFICATION

This project will evaluate and implement the replacement of Ferebee Avenue Pump Station, as it is nearing the end of its useful life. This facility was inspected in 2008, 2011, and August 2013, as part of a Condition Assessment Program administered by Brown and Caldwell. Ferebee Avenue Pump Station was recommended for replacement and/or upgrades under Level 2 in the Rehabilitation program. An in-house hydraulic evaluation in 2014 identified several alternatives for maintaining this station as a lift station or revising its hydraulic capacity and connectivity to function as a terminal station. Final alignment and connectivity (to gravity or to the forcemain system) will significantly impact the design of both the Ferebee Avenue and Park Avenue pump stations. Preliminary engineering evaluations of these two stations will be conducted jointly.

PROJECT DESCRIPTION

This project will replace the inoperable 36-inch horizontal gate valve and install a new 48-inch valve at the intersection of Lee Avenue and Wesley Street in the City of Portsmouth. A Preliminary Engineering Report was completed in November 2007 making these recommendations.

PROJECT JUSTIFICATION

The 36-inch horizontal gate valve is currently stuck in the open position and, due to the configuration of the valve, will not close to allow flow isolation of SF-220 in case of a failure. SF-220 is a 36-inch reinforced clay pipe (RCP) force main that was constructed in 1946. The installation of a new 48-inch valve on SF-221 where SF-221 intersects with SF-220 will allow flow isolation of SF-221 to the north and south of the intersection. SF-221 is a 48-inch RCP force main approximately 15,000 LF long constructed in 1946 with isolation valves only located at each end. The valves will insure proper operation in the event of a failure on these aged force mains.

PROJECT DESCRIPTION

This project is to study the Larchmont area of the City of Norfolk and to develop a comprehensive sewer master plan for infrastructure improvements. The study will investigate and assess from a holistic approach the alternative that best serves the collective interests of HRSD, the City of Norfolk, and the citizens within the studied area. The study will evaluate both conventional gravity collection systems and vacuum systems as viable alternatives. HRSD and the City of Norfolk have agreed to jointly conduct this study and enter into a 50-50 cost participation agreement.

PROJECT JUSTIFICATION

Both HRSD and the City of Norfolk have identified sewer projects in their respective Capital Improvement Programs to address concerns with existing sewer infrastructure. The project area experiences chronic flooding and significant inflow and infiltration. The existing collection system within the Larchmont area has gravitymains in need of repairs due to pipe failures, negative slopes, and root intrusion. Approximately 60 percent of the existing gravity mains are backyard sewers making access for routine maintenance very challenging. The city has expressed a desire to bring these mains into the public right-of-ways and serve residences from the frond-end of the properties. HRSD owns and operates five (5) pump stations within the Larchmont area. These stations are included in the current FY 2018 CIP program under VP015320, they are planned for rehabilitation and/or replacement to address multiple issues.

PROJECT DESCRIPTION

This project is to relocate, rehabilitate, and/or replace five pump stations, and their associated force mains, in the Larchmont area of the City of Norfolk (Monroe Place Pump Station # 114, Hanover Avenue Pump Station #141, Jamestown Crescent Pump Station #142, Richmond Crescent Pump Station # 124, and Powhatan Avenue Pump Station #122). Additionally, the following gravity sewer work will be done if pump station site remains: - Richmond Crescent Gravity Lines (N Trunk Sewer Section A) Rehabilitation - 850 linear feet of 8-inch gravity pipeline and 7 manholes will be rehabilitated/replaced. Project extents are from MH-SG-205-100 to SS-PS-124-1. In addition, 50 linear feet of the Pump Station parallel influent line and the upstream MH SG-205-901 will berehabilitated / replaced. - Jamestown Crescent Influent Line Rehabilitation - 5 linear feet of 10-inch gravity pipeline and 1 manhole will be rehabilitated/replaced. Project extents are from MH-SPS-142-1457 to SS-PS-142-1.

PROJECT JUSTIFICATION

This project will evaluate cost effective alternative locations that may reduce the risk of tidal flooding during severe wet weather conditions. This project will also address issues related to the condition of the wet wells, pumps, motors, controls, appurtenances, and emergency generator/pump for the facilities. The pumps, motors, and controls are nearing useful life and replacement parts are not available. The Richmond Crescent Pump Station was damaged due to flood conditions during the 2009 November Nor'easter. Monroe Place Pump Station has documented flooding issues. Jamestown Crescent and Hanover Avenue Pump Stations are in low-lying areas and condition assessment activities gave evidence that tidal flooding likely occurs during severe wet weather events. For the gravity pipelines, condition assessment activities indicate that these assets present a material risk of failure due to physical condition defects and inflow/infiltration.

PROJECT DESCRIPTION

This project is to rehabilitate and/or replace four pump stations, and their associated force mains, in the Lafayette-Norview-Estabrook areas of the City of Norfolk (City Park Pump Station # 106, Chesapeake Boulevard Pump Station #105, Luxembourg Avenue Pump Station #113, and Ashland Circle Pump Station # 102).

PROJECT JUSTIFICATION

This project will address aging infrastructure pertaining to the condition of the wet wells, pumps, motors, controls, appurtenances, and emergency generator/pump for the facilities. The pumps, motors, and controls are nearing the end of their useful life and replacement parts are not available. The Luxembourg Pump Station buildingis experiencing differential settlement. Ashland Circle Pump Station is in a low-lying area and condition assessment activities gave evidence that tidal flooding likely occurs during severe wet weather events.

PROJECT DESCRIPTION

Contract B consists of furnishing labor, materials, equipment, and temporary facilities for the construction of Preliminary Treatment Facility, Versatile Bioreactor, Supplemental Carbon Storage and Feed Facility, Secondary Clarifier No. 6, Chlorine Contact Channel, Odor Control Facilities, Electrical Upgrades and other facility upgrades.

PROJECT JUSTIFICATION

This project is part of the 2017 Watershed Implementation Plan (WIP) Nutrient Compliance Strategy. The VA WIP, released December, 2010, requires that HRSD reduce the pounds of Total Nitrogen (TN) discharged to the James River Basin from 6 million #TN/yr to 4.4 million #TN/yr by December 31,2016. The VIP process improvements will provide a significant reduction in nutrients to the James River basin and the Elizabeth River. The existing main electrical distribution gear 65SG1 as well as the feeder cables are approaching the end of their expected useful life. The existing incinerator switchgear (USS-1) and feeder cables have exceeded their expected useful life. The equipment has already experienced a catastrophic failure, which resulted in a fire. The existing motor control centers 20 MCC1 and 20 MCC2 are corroded due to long term exposure to sulfides. Infra-red inspections are showing an increasing number of problems associated with these MCCs due to the corrosion.

PROJECT DESCRIPTION

This project is to rehabilitate the wet well at Rodman Avenue Pump Station, the influent manhole, and the influent line. This project will also install a sluice gate, an exhaust fan, and a grinder in the wet well.

PROJECT JUSTIFICATION

This rehabilitation work is necessary to maintain the proper operation of this pump station. In a 2012 study, an outside party concluded that the interior of the wet well was in poor condition. The installation of a sluice gate and wet well exhaust fan are required to ensure the safety of personnel entering the areas. The grinder will improve station operation by protecting the pumps from a high volume of debris and rags.

PROJECT DESCRIPTION

This project is to design and construct a replacement pump station for the existing 1922 Park Avenue Pump Station (PS), based on the recommendations of the Park Avenue and Ferebee Avenue Pump Station Study (VP011010). This project is to include installation of an emergency generator/pump and address the replacement/rehabilitation of 50 linear feet (LF) of the 24-inch gravity influent line.

PROJECT JUSTIFICATION

This project will evaluate and implement the replacement of Park Avenue Pump Station. This facility was inspected in August 2013, as part of a Condition Assessment Program administered by Brown and Caldwell. Park Avenue Pump Station was recommended for replacement and/or upgrades under Level 2 in the Rehabilitation program. This facility experiences operational issues related to aging equipment and structure. Park Avenue Pump Station currently receives flows from HRSD's Ferebee Avenue Pump Station in addition to flow from several city pump stations. An in-house hydraulic evaluation in 2014 identified several alternatives for revising the alignment and connectivity (to gravity or to the force main system) of the Ferebee Avenue Pump Station effluent force main, which may significantly impact the future capacity needs and design of the Park Avenue Pump Station. Preliminary engineering evaluations of these two stations will be conducted jointly.

PROJECT DESCRIPTION

This project will remove a galvanized air vent and reinforced concrete vault installed on a 36-inch reinforced concrete pipe (RCP) on Effingham Street.

PROJECT JUSTIFICATION

This project will address an air vent originally included in GN013900, a Consent Decree required project that addressed air vents with galvanized riser pipes that are vulnerable to catastrophic failure due to severe corrosion. During field investigations, this air vent was discovered to be directly tapped into a reinforced concrete vaultlocated under both north-bound lanes of Effingham Street. Both the air vent and vault appear to have been installed as part of a Virginia Department of Transportation(VDOT) relocation project in 1956. The condition of the vault is unknown, but suspected to be compromised due to exposure to hydrogen sulfide (H2S) gas for over 60 years. Due to the location, unknown condition, and Consent Decree requirement to address the air vent, both assets will be removed from the force main system.
