For decades, a single gap in the public sewer network around Chautauqua Lake has persisted — a stretch of shoreline running from Point Chautauqua to Midway State Park where on-site septic systems remained the only option. In March 2026, Chautauqua County announced that gap would finally be closed: Phase 3 of the South and Center Chautauqua Lake Sewer District (SCCLSD) expansion has secured its critical funding, and construction will proceed following final design, permitting, and financing approvals.

The project is made possible by a $17,795,000 New York State Water Infrastructure Improvement (WIIA) Grant, awarded through the Environmental Facilities Corporation (EFC) on behalf of Governor Kathy Hochul. For Chautauqua County officials, the announcement represented the completion of a promise that predates even the current county government.

County Executive PJ Wendel said: "From day one, completing public sewer around Chautauqua Lake has been one of my top priorities. For years, we've talked about installing that 'golden pipe' to connect the system ends — and now, we're on the verge of making it a reality. This investment protects our environment, supports our tourism economy, and ensures that future generations can enjoy the beauty and integrity of Chautauqua Lake."

The Three-Phase Arc

The SCCLSD sewer expansion has been unfolding in phases, each one extending public sanitary sewer service farther around the lake's perimeter. Phase 1 established initial sewer district service on portions of the shoreline. Phase 2 broke ground in October 2024, extending service along the lake's west side from Stow to Progress Creek (the southern border of the North Chautauqua Lake Sewer District). Contracted to J.D. Northup Construction at approximately $16.9 million, Phase 2 serves more than 400 residents and two campgrounds and is expected to convey approximately 30 million gallons of wastewater annually to the treatment facility in Celoron. Construction runs through spring 2027.

Phase 3 will extend service from Point Chautauqua to Midway State Park along the northeastern shore, completing the full loop of publicly run sewer systems around the lake. According to The Post-Journal, once Phase 3 is complete, the full perimeter of Chautauqua Lake will be served by municipal wastewater infrastructure for the first time.

Environmental and Economic Stakes

Chautauqua Lake sits at the core of a regional tourism and recreation economy that supports hospitality, real estate, and seasonal commerce across western Chautauqua County. The lake has faced documented water quality challenges from nutrient loading — primarily nitrogen and phosphorus from aging on-site septic systems that fail to adequately treat wastewater before it reaches the watershed.

Thomas Walsh, Director of the South and Center Chautauqua Lake Sewer District, said: "Phase 3 represents the final link in a system that will protect Chautauqua Lake for generations. With the support of New York State and our local partners, we are advancing critical infrastructure that reduces nutrient loading, replaces aging septic systems, and strengthens the environmental health of our community."

Chautauqua County Legislature Chairman Pierre Chagnon noted: "Major public works projects like this require determination and sustained support at every level of government. Finalizing public sewer around Chautauqua Lake will fulfill the goal established by County Executive Horrigan in 2013. This is a historic achievement that will improve water quality, strengthen property values, and support the long-term vitality of our lake communities."

How the WIIA Grant Works

The $17,795,000 WIIA grant flows through the New York State Environmental Facilities Corporation (EFC), which administers New York's water and wastewater infrastructure financing programs. WIIA grants are designed to cover a significant share of eligible project costs for communities with demonstrated need — reducing the per-property cost of connecting to municipal sewer service and making these systems financially feasible for lower-density lakeshore communities where the economics otherwise would not work.

A separate county resolution documents an estimated project cost of approximately $10.1 million for one sub-component of the extension in the Towns of Ellery and Chautauqua, with construction required to begin within 24 months of grant award and be completed within 30 months, per county public facilities committee documents. The EFC will work closely with county and sewer district officials as the project advances toward execution of a formal grant agreement and construction milestones.

A County on the Move

The Phase 3 sewer announcement was one of several significant infrastructure and development milestones highlighted in the 2026 Chautauqua County State of the County Address. County Executive Wendel noted that in 2026 the county will treat and maintain more than 660 miles of county roads, complete six culvert and bridge rehabilitations, and undertake two bridge replacements — a combined infrastructure investment exceeding $13 million in roadways alone. The County of Chautauqua Industrial Development Agency (CCIDA) approved or assisted nine projects in 2025 generating more than $84.7 million in new investment, projected to create 639 new jobs and retain 243 more.

Construction Timeline and Procurement

Work on Phase 3 will proceed after final design, permitting, and execution of a formal grant agreement between the EFC and Chautauqua County. With Phase 2 still underway through early 2027, the county and sewer district are managing overlapping construction programs. For contractors and construction firms active in western New York and Chautauqua County, Phase 3 represents a significant civil infrastructure procurement opportunity. The Phase 2 contract — $16.9 million awarded to J.D. Northup Construction — offers a benchmark for the scale of work Phase 3 is likely to require.
