Description
"Inflow is water discharged into sewer lines from such sources as roof drains, cellar and yard area drains, foundation drains, uncapped cleanouts, manholes with missing lids, cross connections between storm drains and sewers, private sewer plumbing, commercial and industrial so-called clean water discharges; and drains from springs and swampy areas. Infiltration is ground water entering sewers and building connections from the soil, through defective joints, broken or cracked pipes, improperly made connections, defective manhole walls, etc. It should be noted that a major source of I/I is from private plumbing (building and facility sewers), and that, in some cases, the volume of I/I from private sources is equal to or greater than the amount of infiltration resulting from defective pipe and joints in public sewers. Especially during and immediately following heavy ran events, but also during periods of high groundwater levels, a significant portion of Fort Worth's wastewater collection system flow is due to Inflow and Infiltration (I/I). In CY2019, rain event Sanitary Sewer Overflows (SSOs) comprised 36% of all Fort Worth SSOs, and 96% of total SSO volume. In 2020, they comprised 22% of overflows and 62% of overflow volume. I/I impacts include: (1) increased capital costs, for upsizing collection system piping and wastewater treatment plant capacity, installing retention basins, etc.; increased treatment plant operating costs; (3) sewer backups and property damage; and environmental damage and potential health impacts, due to sewer overflows. This initiative will reduce system costs and environmental impacts associated with I/I."
Measurable Outcomes
System Metrics - Reductions in: SSOs per 100 miles, capacity (rain event) SSOs per 100 miles, collection and treatment flows and O&M costs, sewer peaking factors, sewer backup property damage, and fish kills and other environmental impacts related to SSOs. Increase in collection system integrity. Operations Metrics - Meeting operational goals is an essential part of this initiative. SMAINS, SSERV, SAM, Supervision and Management are responsible for the number of manholes built/repaired/replaced, sewer mains and services repaired, sewer cleanouts and taps installed, rehabilitation pipe installed, walkouts performed, easements cleared, air-release/aerial crossing/manhole inspected, smoke testing performed, odor control devices/complaints investigated, inspected and installed and response times monitored. SERI, PM, and SPRO, Supervision and Management are responsible for the number routine degrease/root-cuts performed, sewer cleaning (including basins), sewer CCTV performed, manhole inspections, reporting number of overflows/gallons, customer complaints performed, trenchless point repairs installed, internal and external contractor/basin/project/QA-QC CCTV work reviewed, aerial drone inspections, SSO/Stoppage reports completed, SSCA (Sub Basin) Reports completed, and overall response times to our customers.

Support Required
FO-Wastewater Collection Our Wastewater Team composed of SMAIN, SSERV, SAM, SERI, PM, SPRO, Supervision, and Management will continue to work and assist each other daily, weekly and monthly throughout our structured preventative maintenance programs, routine work and emergencies. CD-Pipeline Defects discovered in the collection system that are too large or expensive for Field Operations to repair are referred to Capital Delivery, to be included in rehabilitation and capital improvement projects. SO-Infrastructure Planning & Asset Management Collection system flow monitoring, hydraulic modeling, and support for consulting and professional services contracts are essential to this initiative's success. This section will also support efforts to: (1) reduce private I/I, (2) monitor and mitigate the substantial impact of wholesale customer I/I on our system, and (3) work with Capital Projects, TPW, and Development to implement practices, specifications, and policy changes that reduce the impact of development on I/I. CC-Pretreatment Services Work with customers to mitigate/eliminate private I/I.
