Middle Peninsula Treatment Plants

King and Queen County, formed in 1691 from New Kent, wasnamed for King William, III and Queen Mary. The WalkertonBridge spans the Mattaponi River and the adjacent pier provides aspot for enjoying the natural beauty of the area.

King William County St. John's Church, dating from 1734, has beenbeautifully restored through an effort of over 80 years by the St. John'sChurch Restoration Association.

Middlesex County is home to Deltaville, the “Boating Capitol of theChesapeake;” the Town of Urbanna and the official State OysterFestival; and the restored Buyboat the F.D. Crocket, now on theregister of historic places and viewable at the Deltaville MaritimeMuseum. Middlesex is also the home of the most decorated memberof the Marine Corps, General Chesty Puller, and his resting place. He iscelebrated everyday through the Middlesex Museum in Saluda and isalso honored yearly by a Marine Corps run through Saluda to hisresting place at Christ Church.

PROJECT DESCRIPTION

This project will include: An extension of the North Shore SCADA system to include the Middle Peninsula sites; pumping station improvements at all Middle Peninsula sites; an extension of the HRSD SCADA WAN to include the Middle Peninsula; upgraded remote site telemetry communications; and construction phase services. During the preliminary design phase of the Interceptor System SCADA project, the QST looked to expand the SCADA final design to the Middle Peninsula (MP). The SCADA Preliminary Engineering Report gave the costs for expansion to the MP at $3.3 million. This CIP is for the construction portion of this project. The design is being performed with the Interceptor Systems Pump Station Control and SCADA Upgrades and Enhancements GN012800.

PROJECT JUSTIFICATION

There are multiple benefits to expanding the SCADA project to encompass the Middle Peninsula: Future trends for small communities appear to be decentralized/distributed wastewater treatment systems that will require SCADA for remote diagnosis and operational control; as time goes on, the cost of personnel and the cost of transportation will drive HRSD towards more supervisory control at both the treatment plants and pump stations, starting with the Mathews Transmission Force Main (TFM) pump stations; A major portion of the existing system is obsolete and needs replacement; There are Operational and Maintenance benefits to having the same SCADA system throughout the HRSD system: South Shore, North Shore, and the Middle Peninsula; The WAN microwave ring provides areliable communication link and the existing communication lines could possibly function as a back-up; and if the MP is added to the Consent Decree in the future, then the MP SCADA system would be upgraded to handle the reporting requirements.

PROJECT DESCRIPTION

HRSD Small Communities Division has recently completed the necessary work to reactivate the second biological treatment train, increasing the plant's capacity to 100,000 gallons per day (GPD). Previously the membrane bioreactor (MBR) portion of the second train was used to stage and clean membranes used in the first treatment train. Membrane performance has not met expectations for some time and has required maintenance beyond what was anticipated with the original design. With the reactivation of the second train to meet flow conditions, improvements to the technique used to clean the membranes is required. To support these modified cleaning techniques several improvements are required. These improvements are identified as follows: automation of pulsed membrane backwash with chlorine addition, provision for off-line membrane cleaning, consolidation of chemical storage and metering, Equalization Tank (EQ) pumping, Ultra-Violet (UV) system improvements, and Programmable Logic Controller (PLC) additions. Plant modifications will also be designed and installed to easily accommodate the plant's planned Phase II expansion.


Both King William Treatment Plant (KWTP) treatment trains are able to run simultaneously. The proposed upgrades will provide improved reliability and operations. The flow coming into the KWTP is currently averaging 60,0000 GPD. Development is steadily increasing flows to the plant.

Prog CostExp to


$523 $282 $241 $0 $0 $0 $0 $0 $0 $0 $0 $0

PROJECT DESCRIPTION

This project is to add a tertiary filter and pump station at the West Point Treatment Plant (WPTP), between the secondary clarifiers and the chlorine contact tank. The tertiary filter was formerly part of a side stream process at York River Treatment Plant (YRTP) when the YRTP provided reclaimed water to the Yorktown Refinery and has been relocated to the WPTP for repurposing at the plant. The cost and scope of the project also includes the pump station installation, associated electrical improvements, instrumentation for capturing filter/pump station operating data, and piping to convey process water to and from the filter.


This project will make use of equipment no longer used at the YRTP and increase disinfection reliability at the WPTP. Despite maintaining an unusually high chlorine residual concentration in the chlorine contact tank, bacterial limits are often exceeded at the WPTP. The lack of reliability is due to the high levels of total suspended solids (TSS) and particulates in the effluent. A filter downstream of the secondary clarifiers will significantly reduce effluent solids, which will subsequently reduce disinfection chemical demands/costs and overall treatment reliability.

Prog CostExp to


$3,476 $1,350 $1,818 $308 $0 $0 $0 $0 $0 $0 $0 $0

PROJECT DESCRIPTION

This project is to build a new main vacuum/pumping station in Mathews County on a new parcel that has been purchased. The new station will include a new building, new vacuum pumps, new sewage pumps, new sewage holding tank, trailer-mounted vacuum pump, emergency bypass pump connections, abandonment of the existing Court House pump station, and evaluate the potential of abandoning the existing booster pump station on Buckley Hall Road.


This project will replace the existing Mathews County Main Vacuum/Sewage Pumping Station that has reached the end of its useful life, which will also mitigate risks by providing much-needed redundancy. See the list below for additional details.The existing station conveys all of the sewage from Mathews County to a transmission force main downstream. As such, a catastrophic failure of the vacuum pumps would cause overflows/backups at every vacuum pit and lateral in the system. At the present time, the Small Communities Division cannot respond to such a failure as they do not possess a trailer-mounted vacuum pump and emergency bypass connections are not currently onsite.The existing station is 40 years old and has a buried, carbon steel vacuum collection tank. The existing site is too small to install bypass pump connections and/or raise the buried tank above-ground so it can be regularly cleaned and inspected. There is only 17 feet between the existing station and the adjacent Put-In Creek.Currently, the existing station lead and lag sewage pumps start and stop almost 500 times per day. Additionally, a new subdivision is planned and has been approvedthat will expand the system by approximately 25 percent and reduce available capacity even further.

PROJECT DESCRIPTION

This project involves the replacement of approximately 2,800 LF of existing 4-inch vacuum trunk line as part of the Nursing Home Line in Mathews, VA with new 8-inchvacuum line to connect into a previously installed expansion of 6-inch vacuum sewer, along with associated diversion valves and two new buffer tanks to serve the end of line nursing home vacuum line and the courthouse area. The Courthouse area installation will remove an existing pump station from the system and improve overall operations of the Mathews systems.


The new line will replace an undersized 4-inch vacuum line that causes continuous low vacuum and waterlogging issues due to capacity along the trunk line as well as installation of the buffer tanks at the Nursing home line and Courthouse area to alleviate current and future vacuum pressure issues. A previous upgrade to the system replaced a large section of the original 4-inch vacuum main with 6-inch vacuum main; this project will complete the remainder of the 6-inch vacuum main install along with associated vacuum spur lines.

PROJECT DESCRIPTION

This project involves the purchase of a mobile screw press for dewatering of solids at all of the Small Communities Wastewater Treatment Plant facilities. The work also includes installation of pads, piping, electrical and instrumentation hookups at each facility for quick connection and disconnection of the mobile dewatering unit.


Small Communities currently has sand gravity drain drying beds at two of the four wastewater treatment plants that are operated. The drying beds are very time and labor intensive at the two facilities requiring substantial amounts of both during normal operations and substantially more during wet weather and cold weather. Additionally, the remaining two plants require a pump and haul operation to the West Point Treatment Plant in order to dewater and dispose of the solids. The current operation provides substantial expense to small community operations and does not allow for any future flow growth at any of the current plants. The use of a mobile dewatering unit will allow for extensive reduction in time and labor, removal of the pump and haul operation and provide capacity for additional flows for solids treatment at all plants simultaneously.

PROJECT DESCRIPTION

This project consists of a wastewater collection system to convey wastewater from the Cook's Corner service area to the planned Middlesex Interceptor system. The collection system will consist of approximately 3,200 linear feet of gravity sewer, a submersible pump station, and 1,100 linear feet of force main.


Middlesex County has secured funding for the revitalization of Cook's Corner including a Vibrant Communities Initiative Grant and an Industrial Revitalization Fund Grant. The Industrial Revitalization Fund Grant was awarded in August 2018 and entails completing the revitalization in 18 months. Providing sanitary sewer service to the area is a requirement of these grants. The Memorandum of Agreement between the Hampton Roads Sanitation District and Middlesex County for Cost Sharing of Sewer System Projects outlines that HRSD will manage design and construction of collection system projects on behalf of Middlesex County. The "Project Design" section of the agreement states "All costs incurred by HRSD related to the collection system of any such project shall be reimbursed by the project funds once financing is secured by the County for construction of the collection system." The "Construction" section of the agreement states that "all costs associated with construction, inspection and administration related to the collection system portion of the project shall be included in the project cost and reimbursed to HRSD by the County."

PROJECT DESCRIPTION

The project includes the construction of a 1.8 mile transmission force main (TFM) from the Cooks Corner service area in Middlesex County to the existing Central Middlesex Treatment Plant (CMTP). This is the first phase of the overall Middlesex Interceptor TFM project and will temporarily allow the conveyance and treatment ofthe Cooks Corner development.This program will be divided into discrete interceptor and pump station projects as the scope and sequencing needs of the program elements are further clarified.


Middlesex County has received state grant funds which are being utilized to develop the Cooks Corner sewer service area for public water and wastewater. In order to provide wastewater treatment, HRSD must provide a conveyance pipeline from the proposed development area to the existing CMTP. Though this pipeline will temporarily convey flow from Cooks Corner to CMTP, it will eventually be re-utilized as a portion of the overall Middlesex Interceptor TFM to convey both the CMTP and Cooks Corner flows to York River Treatment Plant.

PROJECT DESCRIPTION

This project includes the construction of a 3.2 mile force main from Urbanna to Cook's Corner in addition to a 13 mile force main along route 33 in Middlesex County from Cook's Corner to the Mathews Force Main (FM). This creates the backbone of the "Middlesex Force Main" solution and includes a Horizontal Direction Drill (HDD) under the Piankatank River. This interceptor system will convey wastewater from Middlesex County to the York River Treatment Plant (YRTP) and be able to decommission both the Urbanna Treatment Plant and Central Middlesex Treatment Plant permanently. The system consists of pump stations, potential storage, and an interceptor force main. This project will also involve provisions for connection of the Topping service area near the intersection of Route 33 and Route 3 and for connection of the Deltaville service area near Hartfield along General Puller Highway.Pump Stations will include Urbanna Treatment Plant Pump Station, Central Middlesex Treatment Plant Pump Station, and two Middlesex Force Main Interim Booster Stations.Additional design considerations may necessitate additional conveyance pump station(s), off-line storage vessels, and improvements to the existing Matthews transmission force main pump stations. These items are not currently included in this CIP cost estimate.


Middlesex County is developing sewer service areas. In order to provide wastewater treatment, HRSD must expand existing Middlesex treatment plants, install decentralized treatment systems, and/or install conveyance from these service areas to existing wastewater treatment facilities. HRSD has two minor (100,000 gpd orless) wastewater treatment facilities in Middlesex County that are near capacity. In addition, the Town of Urbanna has requested HRSD to eliminate surface water discharges. Currently, HRSD must purchase nutrient credits to discharge into the Rappahannock River basin. HRSD has wastewater treatment capacity at the YRTP.The life cycle cost of conveying sewage to the YRTP is less than the cost of constructing and operating multiple minor wastewater treatment plants in Middlesex County. A conveyance system to the YRTP service area mitigates the risk and expense of incremental expansions to existing treatment facilities and of more stringent permitting requirements associated with future development in Middlesex County. Consequently, HRSD's strategy is to convey flows from Middlesex to the YRTP.

This project includes the construction of the following pipelines to provide connection to within 2 miles of individual service areas within Middlesex County to the Middlesex Interceptor Force Main:•A force main towards Deltaville•A force main towards Topping/Grey's Point•A force main towards Urbanna West/Kilmer Lane Additional design considerations may necessitate additional conveyance pump station(s) , additional conveyance storage, and/or improvements to the existing Matthews Transmission Force Main (TFM) pump stations. These additional design consideration items are not currently included in the CIP cost estimate.


Middlesex County is developing sewer service areas. In order to provide public sewer to these areas, HRSD is constructing an interceptor force main through Middlesex County to the existing Mathews TFM in place of expanding/creating new minor wastewater treatment plants. HRSD has wastewater treatment capacity at the York River Treatment Plant (YRTP). The life cycle cost of conveying sewage to YRTP service area is less than the cost of constructing and operating multiple minor wastewater treatment plants in Middlesex County. A conveyance system to the YRTP service area mitigates the risk and expense of incremental expansions to existing treatment facilities and of more stringent permitting requirements associated with future development in Middlesex County. Consequently, HRSD's strategy is to convey flows from Middlesex to the YRTP.

PROJECT DESCRIPTION

The project will consist of converting one of the two existing 44,000 gallon equalization tanks into an Aeration, Anoxic, Anaerobic (A2O) and Integrated Fixed Film Activated Sludge (IFAS) process in addition to automated dissolved oxygen (DO) control of the IFAS and downstream aeration basins. This project may also include the reuse of the tertiary filter from Lawnes Point Treatment Plant (LPTP) to Urbanna Treatment Plant (UBTP), for which cost is not currently included.


To improve reliability for the UBTP to accept increased higher strength loading and flow from Bethpage campground with continued treatment of the Town of Urbanna. Operations continues to see the effect increased flow, and subsequent nutrient and solids loadings, has on the UBTP in periods of peak treatment (both process and hydraulically). These interim upgrades will vastly improve the reliability of the treatment process to handle these increased flows and subsequent loadings while a more permanent outcome is developed and implemented for flows beyond the plant's current 100,000 gallons per day (gpd) permit.
