2026-10-19 · PWSLP, WPCLP · $5.6B in tracked project value · list grew 829 → 904 (SFY2027)
The Illinois Environmental Protection Agency's SFY2027 intended use plans, adopted July 2026, show the combined priority list under the Public Water Supply Loan Program and Water Pollution Control Loan Program grew to 904 projects from 829 prior, a gain of 75, with tracked value at $5.6B. Within that total, 396 projects appeared on the priority list for the first time at a combined $3.0B, while 64 projects entered the fundable range at $725.2M. Cost changes touched 214 projects, 171 up and 43 down, for a net change of +$331.5M on the estimates on file.
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 is in Addison, where the North WWTP Expansion and Upgrades Project entered the fundable range with a requested amount of $125.0M, under the Water Pollution Control Loan Program. Flagg Creek W.R.D. also entered the fundable range, with STP Improvements requesting $68.5M. In Chicago, two projects appeared on the priority list for the first time under the Public Water Supply Loan Program: one to replace approximately 17.53 miles of water mains at a requested $98.2M, and a separate filter rehabilitation project requesting $89.3M. Smaller moves registered too: Cerro Gordo and Warrensburg both climbed in priority rank, with Cerro Gordo requesting $3.1M for tank coating and related work and Warrensburg requesting $1.6M to replace 7,360 LF of 6" watermain.
Across the category rollup, wastewater treatment carries the largest tracked value at $2.7B across 124 projects, ahead of watermain and distribution work at $2.0B across 227 projects. Lead service line projects are the most numerous category at 289, totaling $1.3B, while collection and sewer work totals $1.2B across 101 projects. Wells and source projects total $771.9M across 74 projects, and water treatment totals $661.2M across 106 projects. The spread shows value concentrated in treatment and conveyance work even as lead service line replacement dominates by project count.
The SFY2027 Public Water Supply Loan Program and Water Pollution Control Loan Program documents list these changes without stating why any individual project moved. What is on record is the scale of movement: 904 projects now listed, 64 newly in the fundable range, and $331.5M in net cost change across 214 projects with revised estimates on file.
