This project will also replace the main line valves, branch valves, valve complexes at Valve 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 to MH-SG 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-inch concrete 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 are the main interceptors conveying wastewater from the City of Norfolk to the 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.

The treatment process will be designed to meet an annual average of 5.0 mg/l total nitrogen concentration and a 1.0 mg/l total phosphorus concentration in the effluent discharge. Improvements to existing facilities will also be needed to address the BNR process upgrades including the installation of a distributed control system, grit removal improvements and generator/switchgear upgrades. A number of other site improvements will also be needed on this relatively small and fully utilized site. The improvement project will also include a number of existing CIP projects already scheduled to move ahead. These projects include: Aeration Tank Influent Pipe Replacement, Primary Clarifier Influent Pipe Replacement, Foreign Biosolids Facility Improvements. PROJECT JUSTIFICATION The Virginia State Water Control Board adopted new Water Quality Regulations on November 1, The regulations established mass loading limits by river basin. As part of HRSD's negotiations with VDEQ on the implementation of these limits, it was agreed that at least one plant in the James River Basin would be upgraded to BNR. An HRSD team has determined that the Treatment Plant should be upgraded to meet part of this mass-loading requirement.

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 Blvd 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 There have been two documented repairs in 1964 and in 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.

The project will include structural, architectural, electrical, instrumentation controls, and all associated utilities for a central facility. The project scope includes conveyance of feed solids to the facility; solids screening; dewatering; polymer feed; two-day cake storage; distributive control; and appropriate support utilities. Ultimate distribution of the dewatered solids (e.g. off-site incineration or off-site anaerobic digestion), including requirements for solids screening and cake storage, will be determined subject to update of HRSD's Solids Master Plan. PROJECT JUSTIFICATION Repurposing the incinerator for activated carbon re-generation requires the construction of a separate plant solids dewatering and shipping facility.
