THROUGH THE "SMART WETLANDS" PROJECT, TWI IS WORKING TO SPREAD THE USE OF SMALL TILE-TREATMENT WETLANDS ON PRIVATE FARMLAND AS A NATURAL SOLUTION TO THE CRITICAL ISSUE OF NUTRIENT RUNOFF INTO LOCAL WATERWAYS AND ULTIMATELY, THE GULF OF MEXICO. THE ORGANIZATION PURSUES THIS GOAL THROUGH COLLABORATIVE PARTNERSHIPS WITH AGENCIES AND PEERS IN THE AGRICULTURAL SECTOR, OUTREACH TO RAISE AWARENESS WITH LANDOWNERS AND THEIR TRUSTED ADVISERS, AND TECHNICAL ASSISTANCE TO FARMERS TO BUILD WETLANDS IN NEW COUNTIES AND WATERSHEDS. IN 2024, TWI EXECUTED THE FIRST STEPS IN A NEW BUSINESS PLAN TO EXPAND THE PROJECT'S REACH, INCLUDING FILLING A NEW ENGINEER POSITION TO ASSIST IN DESIGNING AND IMPLEMENTING MORE WETLAND SITES. THIS ADDED CAPACITY LED TO FIVE NEW SMART WETLAND DESIGNS IN PROCESS ACROSS FIVE NEW COUNTIES BY THE END OF THE YEAR. MEANWHILE, TWI FORMALIZED SEVERAL EXISTING AND NEW PARTNERSHIPS TO BEGIN A THREE-YEAR, STATEWIDE COORDINATED EFFORT TO INCREASE THE USE OF ON-FARM PRACTICES FOR WATER QUALITY IMPROVEMENT IN ILLINOIS, INCLUDING TILE-TREATMENT WETLANDS. FINALLY, DURING 2024, TWI BEGAN FORMING NEW PARTNERSHIPS TO EXPLORE DEPLOYING THE SMART WETLANDS CONCEPT AND PRACTICE IN INDIANA'S EXTENSIVE FARMING REGION.TWI IS ALSO EXPLORING OTHER INNOVATIVE WAYS THAT WETLANDS CAN BE INTEGRATED INTO THE FARM LANDSCAPE FOR CLEAN WATER. IN THE LAKE SPRINGFIELD WATERSHED, IN 2024 TWI WORKED WITH THE CITY OF SPRINGFIELD'S CITY WATER, LIGHT, AND POWER UTILITY TO PURSUE THE USE OF LARGER, SPECIALLY DESIGNED TREATMENT WETLANDS ON PUBLIC AND PRIVATE PROPERTIES TO ADDRESS DRINKING WATER IMPAIRMENTS. FUNDING THROUGH THE STATE REVOLVING LOAN FUND COULD HELP MAKE THIS A REALITY, WITH POTENTIAL FOR IMPLEMENTATION ELSEWHERE IN ILLINOIS TO PROVIDE CLEANER DRINKING WATER. THE WETLANDS INITIATIVE IS INCREASINGLY PLANNING AND IMPLEMENTING ITS WORK WITH A FOCUS ON THE POWERFUL ROLE THAT WETLAND RESTORATION CAN PLAY IN ECOLOGICAL AND SOCIETAL ADAPTATION AND RESILIENCE TO CLIMATE CHANGE. THE MIDWEST'S CLIMATE IS ALREADY SHIFTING TO MORE-INTENSE RAINFALL EVENTS, LONGER DRY SPELLS, AND IRREGULAR SEASONAL PRECIPITATION PATTERNS. RESTORED FRESHWATER WETLANDS PROVIDE RESILIENCE FUNCTIONS THAT INCLUDE STORING PRECIPITATION AND RUNOFF, MITIGATING LOCAL FLOOD RISKS, RECHARGING GROUNDWATER SUPPLIES DURING DROUGHTS, FILTERING AND PROCESSING NONPOINT SOURCE POLLUTANTS, AND PROVIDING HABITAT REFUGES FOR DIVERSE SPECIES, AS WELL AS SEQUESTERING SOME ATMOSPHERIC CARBON IN HIGHLY ORGANIC SOILS. TWI'S VISION IS FOR THESE NATURAL "SPONGES" TO BE ONCE AGAIN SCATTERED ACROSS THE FLAT MIDWESTERN LANDSCAPE.

As filed on the 2024 return. The filer continues this part on Schedule O, which is not shown here. A text marked withheld matched a screen for wording that may name a private individual, such as an honorific or "in memory of". Most of what it withholds names no one; it is withheld so that what does is never shown.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. A Schedule J breakdown is as filed: base pay, bonus, other, deferred compensation and nontaxable benefits from this organization, with any from related organizations beside each, and the filer's own total. It is shown with the Part VII listing of the same name on the same return. The form gives no key between the two, so that pairing is ours, and is marked matched by us. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all. Showing the 10 most recent; the API carries the rest.

Other IRS files
Auto-Revocation List
Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.
Publication 78
Listed as of 11 November 2026, under deductibility PC.
These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
