County-wide projects:

Miscellaneous Sewer Rehabilitation:

This project continues our “find and fix” program of sanitary sewer rehabilitation to reduce infiltration and inflow (I&I) in our system. This work will utilize two publicly bid miscellaneous sewer rehabilitation contracts that are renewable on an annual basis up to four times after the initial year long contract. They will be used to make repairs and rehabilitate problems in our system found with systematic CCTV inspection by ACSA crews and the subcontractor. FY2022 Budget: $400,000

Supervisory Control and Data Acquisition (SCADA) Implementation:

The ACSA has more than 40 critical assets that include water and wastewater pump stations, water storage tanks and master PRV stations.  This project continues implementation of the ACSA’s SCADA system that allows ACSA employees to remotely monitor the operations of these critical assets.  Total Budget: $2,740,800

Advanced Metering Infrastructure (AMI) Implementation:

This project addresses a goal in our upcoming Strategic Plan to convert our existing metering system to an AMI System. It will include the development of a Request for Proposals (RFP), evaluation of potential vendors, the negotiation of a final contract, and the initiation of a proof of concept phase in FY 2020. Total Budget: $8,200,000

Energy Audit:

This project will consist of a comprehensive energy audit of the Operations Center and all pump stations. It will evaluate current energy consumption and the factors that drive it, as well as, an analysis of utility rate structures to identify potential cost savings. Surveys will be conducted on all systems, including operation and maintenance procedures to determine where energy conservation can be improved. This will result in an analysis of our energy footprint and recommendations for improvements. Total Budget: $300,000

Risk Assessment Improvements:

As part of the on-going preparedness program for the ACSA to remain resilient a Vulnerability Assessment was completed in conjunction with our community partners. All our critical assets were analyzed for risks caused by both natural and human-made hazards, using the AWWA Standard J100: Risk and Resilience Management of Water and Wastewater Systems. The result was a report to establish mitigation measures to lower risks and increase resiliency. Some mitigation measures such as industrial strength locks, perimeter security lighting, and access control signage have been completed. Total Budget: $1,063,950

Enterprise Resource Planning (ERP) Transition:

In 2018 ACSA staff discovered that Microsoft’s mainstream support of Dynamics AX, the financial software platform installed by the ACSA in 2016, would expire October 2021. This project will consist of consulting services provided by the Government Finance Officers Association (GFOA) to assist with a review of business processes and technology, an implementation roadmap, and RFP development/review of proposals/contract negotiations. Total Budget: $608,150

Sewer Pump Stations Comminuters:

Three sewer pump stations: Glenmore, Georgetown Green, and Crozet have all been experiencing higher than normal amounts of solid debris that have been causing undue wear and tear on our pumps, reducing their effective life. They have also been subjected to clogging from the fibrous cloth wipes that are marketed as flushable but do not break down in the sanitary sewer collection system. Maintenance identified the need to install comminuters (AKA grinders) in the wet wells or just upstream of them, to eliminate these solids that are adversely impacting our pumps. Total Budget: $731,300

Exclusion Meters Replacement:

In the mid 1990’s with the development of Glenmore, many new customers installed irrigation systems for their properties and wanted to have their sewer bills reduced by the amount of water that was diverted to irrigate their properties. Private meters were installed behind their ACSA meter to record this volume and it was “excluded” from the calculation of their sewer charges. On January 1, 2006 the ACSA Rules and Regulations were modified to no longer allow exclusion meters and required that all future irrigation meters would be tapped separately off our water mains, to be owned and controlled by the ACSA. This project is a multi-year replacement program by our in-house CIP Crew to install dedicated, ACSA owned irrigation meters that will eliminate all remaining exclusion meters in our system. Total Budget: $1,400,000

4-Story Residential Backflow Device Retrofit:

In late 2018 ACSA staff became aware of 4-story residential structures being constructed without proper backflow prevention devices.  Section 8 of the ACSA Rules and Regulations details the ACSA’s Backflow Prevention Program.  This program is in accordance with 12VAC5-590-570 through 12VAC5-590-630 of the Virginia Waterworks Regulations.  The Containment Policy in 12VAC5-590-610 outlines the requirement for a backflow prevention device (BFP) device on the domestic water servce line to high rise structures, defined as four (4) or more stories.  Total Budget: $348,000

Pipe Saddles Replacement:

The ACSA Maintenance Department has discovered in recent years that pipe saddles used to make water service line connections to PVC water mains have been failing. This project is a multi-year replacement program to be undertaken with our in-house CIP Crew. Total Budget: $200,000

Developer Participation:

Each year funds are set aside to participate in over-sizing utilities constructed to serve new development. The Rate Model includes $100,000 divided equally between water and wastewater projects as a contingency to insure the new pipes are sized to meet the ACSA’s long-range needs. Total Budget: $100,000
