BACKGROUND:
On January 5, 2021, the Mayor and City Council approved Resolution No. 7613, committing to water conservation through the reduction of non-revenue water in order to comply with the allocation requirements of the Level of Lake Michigan Act, 615 ILCS 50, and the corresponding State regulations. A condition of the City’s Lake Michigan water allocation permit is completion of the City’s Non-Revenue Water Reduction Plan. A component of this plan is dividing the City’s water distribution system into smaller zones where the water loss in each zone can be monitored. These “zones” are referred to as “district metered areas,” called “DMAs”. A consultant that specializes in design and implementation of DMAs is needed to design and implement these DMAs.
In January 2024, the City published a Request for Qualifications for the Water Loss Control Technical Assistance Program. Seven qualifications were received, four firms were interviewed, and the selection committee identified Cavanaugh & Associates PA, as the most qualified firm to complete the services for the program.
Cavanaugh & Associates PA is currently under contract as program manager of the City’s 2025 Water Loss Control program. One scope item in that contract is analysis of the City’s water distribution system to identify where additional metering sites should be installed. These additional metering sites will allow for the City’s water system to be subdivided into smaller zones so that areas of elevated water loss can be identified. Cavanaugh & Associates PA has completed the planning portion of the DMA project and is now ready to move into the detailed design phase of the project. The City currently has six (6) DMAs. This project will design the installation of 23 additional meters to establish an additional six (6) DMAs (resulting in a total of twelve [12] DMAs.)
Cavanaugh & Associates PA was requested to provide a proposal to complete the detailed design work for the project which is not included in their current contract’s scope of work.
The Public Service Committee will review this matter.
CONCLUSION:
Cavanaugh & Associates PA provided a proposal, in an amount not-to-exceed $155,428.70, to complete detailed design and implementation of the District Metered Area project. The scope of work of the project includes: coordination with City staff to validate proposed DMA boundaries; detailed design of the meter sites; bidding of the project; construction administration for meter chamber installations; development of performance specifications for meter equipment and data integrations; solicitation of proposals from preferred vendors for installation of metering equipment and provision of data-as-a-service (DaaS) with integration to Xylem Vue; design and data-mapping for 12 new DMA supply formulas, with incorporation of all production meters, district meters, and distribution storage tank meters; and design support for the Xylem Vue development team to achieve desired data visualizations within the DMAs.
Section 2-438 of the City of Joliet Code of Ordinances states that purchases whose estimated cost is in excess of twenty-five thousand dollars ($25,000.00) may be awarded without written specifications or bidding under certain circumstances. Two (2) of these circumstances apply:
(f) Purchases when authorized by a concurring vote of two-thirds (2/3) of the Mayor and City Council;
(g) Purchases of professional services.
Funds will be charged to the Water & Sewer Improvement Fund / Meters / Professional Services (Org 50180320, Object 557200, $155,428.70).
