Board adds $67,000 to sewer asset-management task order to operationalize GIS dashboard
Summary
The board approved a $67,000 amendment to the LJA task order to help implement a living sewer asset-management plan tied to ARPA grant requirements and to build staff procedures for ongoing updates to a GIS-based dashboard.
The Water Resources Board on May 27 approved amendment number 1 to an existing task order with LJA to add $67,000 for implementation support of a sewer asset-management plan.
Staff said the asset-management plan was required to secure the final 20% of American Rescue Plan Act (ARPA) funds and that the plan goes beyond a compliance deliverable: it includes a web-based dashboard and processes to make the plan a “working and living document” for operations and maintenance.
Travis (Staff member) led a presentation describing the dashboard and how asset scoring works. The plan inventories sewer system assets and scores each by likelihood and consequence of failure using an industry-standard (ASTM) scoring matrix. Travis said the system includes 47,536 service laterals, 17,903 gravity mains, almost 18,000 manholes, roughly a quarter-million linear feet of force mains, 46 pump stations and 19 junction boxes, and that the agency has inspected roughly 86% of the system via CCTV (about 30% in the last 5 years, 21% within 5–10 years and 34% older than 10 years).
Travis said LJA will assist staff in creating standard operating procedures so O&M and GIS staff can keep the dashboard updated internally. Board members discussed whether other city departments could use the process; staff said the City Works software in use at O&M is built to work with an asset-management approach and that departments such as stormwater could adopt similar methods if they developed comparable GIS data.
A motion to amend the task order to add $67,000 was made, seconded and carried. Staff said the amendment would be funded from previously allocated ARPA grant management funds and that the ARPA paperwork related to the asset-management plan is complete and awaiting final reimbursement from TDEC.
