Chesapeake-Elizabeth Treatment Plant Chesapeake Blending the best of urban and rural life, the City of Chesapeake remains a great place to live, work and raise a family. With a strong commitment to preserving both its historic and natural resources, coupled with a focus on a thriving future, the City has anchored the heart of Hampton Roads for more than 50 years. Norfolk Berthed at Nauticus, the Battleship Wisconsin is one of the largest and last battleships ever built by the U.S. Navy. Virginia Beach King Neptune overlooks the Virginia Beach boardwalk and the 31st Street oceanfront park. Designed by P. DiPasquale, it is the largest cast bronze figure erected in the U.S. since the U.S. Marine Corps (Iwo Jima) Memorial in Washington, DC.

This force main runs through highdensity neighborhoods along Diamond Springs Road and cannot be isolated or diverted. The valve complexes will provide contingency capabilities for any catastrophic failure.

The cost estimate is based on a 48-inch force main; however, the HART study may determine an alternate size. PROJECT JUSTIFICATION This project will replace the line that was installed in 1977 and runs through the high-density neighborhood of Lawson Forest and along Diamond Springs Road. Accessibility and isolation of this force main is extremely difficult to perform due to residential easement encroachment and lack of main line valves. Risk has been assessed at high due to impacts associated with possible line failure. Interceptor force mains installed prior to the early 1980's were not installed on grade to control air entrapment. The use of PCCP and the existence of unknown high points represent significant risk with respect to internal corrosion as well as reduced hydraulic capacity due to reduction in cross sectional area.

A component of the project will involve evaluating the existing station to determine if the hydraulicscan be improved by rebuilding at the same site. If this is not practical other sites will be investigated. PROJECT JUSTIFICATION This project will replace the Quail Street PRS that is 27 years old with the original pumps and motors, and is not operating efficiently due to the yard piping and internal piping configuration (too shallow). Air entrainment in the header system is also an ongoing problem. Proper operation of the station is critical during periods of high flow in order to reduce operating pressures in parts of Norfolk and Chesapeake (the station is bi-directional).

PROJECT JUSTIFICATION The HRSD Hydraulic Analysis group has determined the existing HRSD force main attached to the Lesner Bridge can be removed from service. Results of a hydraulic analysis have determined impacts to system hydraulics in Shore Drive and Great Neck Road are acceptable. The existing HRSD force main attached to the Lesner Bridge will need to be removed from service prior to May 2014 in order to facilitate the start of construction on the new Lesner Bridge. As part of the project terminal pressure sensors willbe installed at the ends of line SF-020 to remain in service.

The study was initiated in July 2011, with three years allowed for pilot testing work. The pilot is evaluating the performance ofeither an initial “A-stage” high rate activated solids or anaerobic treatment process followed by a “B-stage” MLE operating in nitrite shunt (nitritation-denitritation) mode and Mainstream Deammonification processes as follows: “A-stage” high rate activated solids (HRT ~ 0.5 hr; SRT ~ 0.5 day). This process has worked as expected but with some issues associated with Thiothrix spp bulking due to incoming sulfide and volatile fatty acids. Ongoing and future work include the reconstruction of a more plug flow pilot and investigation of the potential for better controlling effluent COD under a range of wastewater temperatures. “B-stage” MLE: Effluent from the A-stage is split to two separate pilot units. The B-stage MLE represents the more conventional MLE BNR process configuration. This process operated as expected in a traditional nitrification-denitrification mode using ammonia-based aeration control at 25 °C. The system has now been optimized for nitrite shunt and has been able to provide very low effluent total nitrogen (TN) concentrations without supplemental carbon but with some instability that seems to have been corrected with aeration control system improvements. Settling performance has been erratic. “B-stage” Mainstream Partial Nitritation-Anammox (Deammonification): A-stage effluent or plant Non-Potable Water (NPW) is also used to feed a pilot partial nitritation-activated sludge process, followed by a fully anoxic moving bed biofilm reactor (MBBR). The controls used to achieve nitriteshunt in this system have been found to be more robust that in the MLE, and the nitritation effluent has been controlled such that an appropriate blendof nitrite and ammonia has been fed to the MBBR, resulting low effluent Total Inorganic Nitrogean (TIN). Settling performance has been poor. The pilot system was reconfigured during the spring of 2013 to provide all of the features in a single pilot train that haveworked best so far. This system includes a pilot A-stage tied to a downstream B-stage, an experimental A-stage to allow testing on this process. The B-stage includes both the nitritation-denitritation reactor system and controls that have provided the best and most stable TN removal to date, as well as the anammox MBBR for effluentpolishing. Settling problems in the B-stage will be addressed by incorporating a hydrocyclone for biomass wasting that should result in gravimetric selection of better settling mixed liquor. Testing will be performed under the expected range of wastewater temperatures and conditions. An EPA proposal was submitted and was fundedto help cover the costs of the pilot testing. The project timeline has been extended until June 2015. PROJECT JUSTIFICATION In addition to ongoing plant upgrades, the HRSD Nutrient Compliance Planning Team has proposed upgrading the CE to meet the Virginia Watershed Implementation Plan (WIP) 2021 allocation of 3.4 million lbs/yr. This project attempts to dramatically reduce the capital andoperating costs of the CE upgrade as compared to the baseline alternative (not pilot tested), which includes construction of primary clarifiers, significant expansion of existing aeration tanks to provide biological nitrogen removal (traditional nitrification/denitrification), and construction of deep-bed post denitrification filters. The capital cost of this alternative is anticipated to be approximately $125-150M. If the A/B process with MLE B-stage can be implemented, it is estimated that the required aeration basin volume could be decreased for a capital cost savings of 25%. If the A/B process can be further optimized to operate in nitrite shuntmode with polishing using an anammox MBBR, this upgrade could be done with no reliance on supplemental carbon while at the same time achieving very low effluent TN concentrations.

PROJECT JUSTIFICATION Lab analysis of pipe core sample taken near Aragon Drive and Diamond Springs Road showed the immediate areas around the sample is at material risk of failure. Extents of the project to be determined in the design phase which would include additional sampling of pipe cores. This project will also be needed to insure reliability and enable support for the planned ChesapeakeElizabeth Treatment Plant closure and diversion of flow to the Atlantic Treatment Plant.

Onsite projects needed at CETP include but are not limited to storage facilities, pump station improvements, odor control, preliminary treatment facility improvements, electrical distribution and backup systems, piping, instrumentation and control with automation, automated valves, stormwater improvements, and demolition of portions of the existing treatment facility. PROJECT JUSTIFICATION The Chesapeake-Elizabeth Treatment Plant Feasibility Study completed by HRSD in October 2013 evaluated taking the treatment plant offline and diverting flow to other treatment plants. The study determined that the HRSD interceptor system and remaining treatment plants have the ability to serve the current and projected needs of the South Shore jurisdictions when the ChesapeakeElizabeth Treatment Plant would be taken offline in 2021. Significant capital and O&M savings from this decision results in a high net present value compared to the former strategy.
