Achieving Favorable Credit Ratings for Two Billion Dollars in Clean Water Investments

The Allegheny County Sanitary Authority serves Pittsburgh and 82 surrounding communities with complex wet weather challenges. Our team provides comprehensive financial modeling and bond engineering to support a multi-billion dollar Clean Water Plan, securing favorable credit ratings and ensuring long-term affordability for a diverse regional population.

Financing Large-Scale Wet Weather Controls While Balancing Diverse Municipal Needs

The Authority must manage a 250-mgd treatment system and implement a massive wet weather Consent Decree. The challenge involves developing a comprehensive financial strategy that integrates proactive capital improvements with the diverse financial capabilities of 83 member municipalities, ensuring regionalization efforts remain affordable.

Integrated Affordability and Bond Coverage Projection Modeling

Our team bridges the gap between raw municipal data and regional action by utilizing a comprehensive financial model to support a multi-year rate-setting strategy. This technology integrates projections for revenue, affordability, capital financing needs, and bond coverage over broad planning periods. By evolving this dynamic model, our team incorporates raw data on intermunicipal trunk sewers and treatment capacity into actionable financial strategic plans. This approach enables the Authority to demonstrate fiscal strength to rating agencies, resulting in favorable Aa3 and AA- bond ratings. The model also supports regionalization efforts by providing a framework for the institutional and financial analysis of municipal asset transfers. This transforms complex regulatory mandates and construction costs into a structured, affordable long-term wet weather control plan. The tool allows for periodic rate-setting support that facilitates political and public acceptance of proactive infrastructure investments.

Secured Two Billion Dollars in Financing with High Bond Ratings

The Authority successfully issued approximately $2.0 billion in bonds to support its Clean Water Plan. Our team's financial modeling enabled a rate-setting strategy that achieved stable, high credit ratings, ensuring the long-term sustainability and affordability of regional wastewater services.
