Full report
The Allegheny County Sanitary Authority (ALCOSAN) is preparing to issue up to $500 million in new debt to sustain the capital-intensive rollout of its Clean Water Plan. During a July 16, 2026, meeting, the ALCOSAN Finance Committee unanimously recommended authorizing the Series 2026 bonds, advancing one of the largest single bond issues in the utility's history to the full board for final approval.
The massive borrowing package is driven by escalating construction activity, particularly on the Ohio River Tunnel project. According to Charlie Goodwin, managing director at FSL Public Finance and ALCOSAN's financial advisor, the authority expects to draw heavily on its construction fund in the coming months.
To meet these obligations, approximately $400 million of the bond proceeds will be injected directly into the construction fund to ensure timely payments to contractors. Another $88 million will be used to refinance existing bonds issued in 2016, which reach their call date this December. The refinancing is projected to save ALCOSAN $2.6 million over the next few years, helping to mitigate the budgetary impact of the authority's growing debt service profile. An additional $3 million will cover issuance costs.
Goodwin indicated that ALCOSAN plans to issue fixed-rate, long-term bonds with a final maturity of 2058, securing an estimated all-in interest rate of 5%. Despite recent volatility in the U.S. Treasury market, Goodwin noted that the tax-exempt municipal bond market has remained relatively stable, buoyed by $29 billion in year-to-date mutual fund inflows and manageable supply levels.
To handle the placement of the $500 million issue, the Finance Committee recommended retaining the same underwriting syndicate used for ALCOSAN's 2025 bond sale. JPMorgan will serve as the senior underwriter, selected for its large capital base, which provides a backstop to purchase unsold bonds into its own inventory if necessary. The syndicate also includes Samuel Ramirez, PNC, Raymond James, Siebert Williams, and Huntington Securities.
The Director of Finance warned the committee that ALCOSAN will be "frequent flyers" in the bond market, requiring substantial annual debt issuances over the next several years to fund its ongoing infrastructure overhaul.
The full ALCOSAN board is scheduled to vote on the bond authorization and syndicate appointment next week. If approved, the authority plans to price the bonds in early November and close the transaction by early December.
