This session explores the Hampton Roads Sanitation District’s (HRSD) strategic decision to reduce capacity-related sanitary sewer overflows (SSOs) mandated by federal Consent Decree across its service area through a collaborative delivery method utilizing Public-Private Education Facilities and Infrastructure Act (PPEA) procedures. PPEA enables public agencies to form partnerships with the private sector to complete major educational and infrastructure projects. HRSD provides sewer conveyance and treatment services for 20 cities and counties (Localities) and nearly two million people in Southeastern Virginia. Faced with regulatory mandates and complex infrastructure needs, HRSD selected Progressive Design-Build to provide flexibility, innovation, and alignment with stakeholder goals throughout the program's complex, interrelated, and geographically diverse projects As a part of the program, the engineering-led design-build team conducted extensive efforts including studies, designs, and is now rehabilitating locality and privately owned sewer systems to reduce inflow and infiltration and eliminate SSOs. The presentation will highlight unique aspects of the inflow and infiltration reduction program that made collaborative delivery the right fit, including team formation, early engagement, risk management, and schedule optimization. Attendees will gain insight into how HRSD’s approach fosters transparency, optimizes SSO reduction, and sets a precedent for future programs under similar regulatory constraints.
