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. They will be used to make repairs and rehabilitate problems in our system found with systematic CCTV inspection by ACSA crews and the subcontractor. FY2023 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 addresses the ACSA’s Strategic Plan initiative of reducing our energy consumption.  We recently completed a comprehensive energy audit of the Operations Center and all pump stations.  Implementation of several recommendations from the audit will occur in FY 2023. Total Budget: $390,000

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

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: $742,500

4-Story Residential Backflow Assembly Retrofit:

In late 2018 ACSA staff became aware of 4-story residential structures being constructed without proper backflow prevention assemblies.  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 assembly 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: $100,000

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

ACSA Facility Projects:


Data Management and Dashboarding:

 Following a needs analysis, dashboards will be developed to display relevant data to ACSA staff directly related to their specific job responsibilities. This Project was a recommendation from our recently completed IT Security Assessment. Total Budget: $40,000

Billing System Analysis and Replacement:

The ACSA’s current billing system has been in use for more than 30 years and is in need of replacement.  Integrating a new billing system with AMI and our ERP system will be critical to the overall success of these efforts. This project will include assessment, RFP development and analysis, contract negotiations and full implementation of a new billing software. Total Budget: $100,000

ESRI Utility Network Implementation:

Following a feasibility study and data readiness analysis, the utility network will allow our organization to model assets with a greater level of detail and will allow staff to quickly identify which valves to operate and customers impacted in the event of a water main break. Total Budget: $200,000

Cityworks Operational Insights Implementation:

Operational Insights is an extension of the Cityworks software that is used by ACSA staff on a daily basis for our computerized maintenance management software.  The primary goal of Operational Insights is to identify infrastructure risks and to evaluate maintenance and replacement strategies.  This software will also assist staff with strategic decision making for future CIP projects. Total Budget: $45,000

Security System Upgrade:

This Project is a direct result of recommendations from both our Vulnerability Assessment and our IT Security Assessment, and positions the ACSA for expansion as we develop the Avon Street Property. Total Budget: $158,000
