2026-11-05 · PWSLP, WPCLP · $8.0B in tracked project value · list grew 829 → 904 (SFY2027)
The Illinois Environmental Protection Agency's SFY2027 intended use plans for the Public Water Supply Loan Program and the Water Pollution Control Loan Program, adopted July 2026, now carry 904 projects, up from 829 in the prior cycle, a net gain of 75. Tracked value across the current list stands at $8.0B. This cycle saw 396 projects appear on the priority list for the first time, together requesting $3.0B, while 64 projects entered the fundable range, representing $725.2M in requested amounts. Cost estimates changed on 214 projects, 171 up and 43 down, for a net movement of $331.5M. The list does not say why some projects are no longer listed.
Contract 21-092-3P Battery E Activated Sludge Facility.. Requested $325.0M.
North WWTP Expansion and Upgrades Project.. Requested $125.0M.
Replace approx. 17.53 miles of water mains. Requested $98.2M.
The most concrete movement this cycle belongs to Chicago, which appeared on the priority list for the first time with two large entries: a request for $98.2M to replace approximately 17.53 miles of water mains, and a separate $89.3M request tied to rehabilitation of existing mono-media sand filters under the Drinking Water program. Addison and Flagg Creek W.R.D. moved into the fundable range on the Clean Water / Wastewater side, with Addison's North WWTP Expansion and Upgrades Project requesting $125.0M and Flagg Creek W.R.D.'s STP Improvements requesting $68.5M. Cerro Gordo and Warrensburg climbed in priority rank under the Drinking Water program, with Cerro Gordo's elevation tank coating and control system work requesting $3.1M and Warrensburg's request for $1.6M tied to replacing 7,360 LF of 6" watermain.
Across the category rollup, wastewater treatment carries the largest tracked value at $2.7B across 124 projects, followed by watermain and distribution work at $2.0B across 227 projects. Lead service line projects post the highest project count among the categories shown, 289, with $1.3B in tracked value. Collection and sewer work totals $1.2B across 101 projects, while wells and source projects and water treatment projects sit further down the value scale at $771.9M and $661.2M respectively, across 74 and 106 projects.
The spread between high project counts and high dollar values, lead service lines leading on count, wastewater treatment leading on value, reflects the mix of many smaller replacement projects alongside fewer, larger treatment plant upgrades on the current list. With 64 projects now in the fundable range carrying $725.2M in requested amounts, that roster marks the closest signal to imminent procurement among the SFY2027 Public Water Supply Loan Program and Water Pollution Control Loan Program entries tracked this cycle.

Projects seeking SRF financing — not every municipal water or wastewater project in Illinois. Source: Illinois Environmental Protection Agency — Public Water Supply Loan Program, Water Pollution Control Loan Program (IUP/PPL). Lead service line replacement projects are included: Illinois EPA lists them separately in its drinking-water IUP and scores them under its lead-line rules (Part 663), so their priority scores aren't comparable with other drinking-water projects' scores. Stages are labeled precisely; "no longer listed" does not assert an outcome.
