PROJECT DESCRIPTION
This project is to study, design and construct a replacement interceptor for Line SF-04, approximately 9,460 ft of 24-inch cast iron pipe and 5,585 ft of 20-inch cast ironpipe and Line SF-05, approximately 12,559 ft of 20-inch reinforced concrete pipe. This project will also replace the main line valves, branch valves, valve complexes atValve Guides AB-2001 and AB-2005 and replace yard valves and wall sleeves at the Terminal Boulevard Pressure Reducing Station. A single line is planned to replace these twin lines along the current alignment. HART analysis has determined the replacement pipe size to be 30-inch. This project also includes abandoning a portion of line SG-003, a section of gravity pipe from MH-SG-003-3889 to MH-SG-003-3747 at the intersection of Baker Street and Hampton Boulevard that is not in service and is deteriorating. The City of Norfolk Department of Utilities has requested that HRSD's design and construction package include 2,300 linear feet (LF) of 24-inch diameter waterline replacement along Hampton Boulevard between Terminal Boulevard and Baker. The construction value of this work is estimated at $1,900,000 and will be reimbursed by the City to HRSD in accordance with a pending agreement.
PROJECT JUSTIFICATION
This project will address SF-04 that was designed and built in 1956 according to the plans inherited from the City of Norfolk. The same plans show an existing 20-inchconcrete line, now HRSD line number SF-05. Since SF-05 was turned over to HRSD in 1956, it is at least 50 years old. Both lines have multiple repairs installed by HRSD and repair history prior to HRSD ownership is unknown. Multiple branch valves along this alignment are 1948 or 1956 valves that are difficult to repair or get replacement parts. The valve guide AB-2005 has several inoperable valves and an abandoned dead-end section of pipe that has a high risk of failure. These lines arethe main interceptors conveying wastewater from the City of Norfolk to the Army Base Treatment Plant. This project also includes abandoning the gravity line SF-002.Flow is currently bypassing this section of pipe and the pipe is in poor condition from tuberculation and infiltration.

PROJECT DESCRIPTION
This project is to study, design and construct a replacement interceptor for Line SF-06, approximately 2,642 linear feet (LF) of 10-inch cast iron force main that is the discharge line from HRSD Pump Station #117 (North Shore Road). This project will include replacement main line valves, branch valves, associated appurtenances and replace the existing force main through the walls into the pump station. HART analysis has determined that this force main will be downsized from 10-inch to 8-inch. The City of Norfolk Utilities Department needs to replace their 24-inch waterline along Hampton Boulevard in conjunction with HRSD Force Main replacement. Therefore schedules need to align.
PROJECT JUSTIFICATION
This project will replace the 61 year old cast iron force main that was installed in 1948. There have been two documented repairs in 1964 and in 2005. Operations staff believes that there are additional undocumented repairs on the line as well. The pipeline is of a material and age for which HRSD has seen recent repeated failures in other parts of the interceptor system due to wastewater chemistry and soil corrosion.

PROJECT DESCRIPTION
This project will construct a new pump station and force main to convey treated secondary clarifier effluent from Army Base Treatment Plant to the VIP Treatment Plant for further treatment in a combined SWIFT facility. The proposed firm capacity of the pump station is 15.6 MGD. The proposed force main is estimated to be 30 inch diameter. The proposed route requires the use of multiple installation methods, including conventional trenching, horizontal direct drilling across the Lafayette River, and micro-tunneling underneath the Norfolk Marine Terminal railroad tracks. The location of this pump station has not been identified. The scope of the project does not include property or easement acquisition, equalization tank construction, or treatment process upgrades.
PROJECT JUSTIFICATION
Implementation of full scale SWIFT treatment at HRSD wastewater treatment plants discharging to the James River is needed to reduce nutrients entering the Chesapeake Bay, augment the groundwater supply, reduce the rate of ground subsidence, protect groundwater from saltwater intrusion, and support Virginia's economy. The SWIFT master planning effort has determined that advanced water treatment and aquifer recharge at Army Base has significant physical limitations including site availability. This project would support the capture and further advanced treatment of Army Base secondary clarifier effluent in a consolidated SWIFT treatment facility located adjacent to VIP.
