LARGO, MD, MARCH 15, 2019 -- The Clean Water Partnership (CWP), a 30-year community-based public-private partnership (CBP3) between Prince George's County, Maryland and Corvias, has completed the initial pilot phase in half the time, under budget, all while increasing outreach to key community stakeholders and investing in Prince George's County's small minority and disadvantaged businesses.

"Corvias elevates what municipalities can do on their own and turns daunting and costly regulations into thriving programs with benefits beyond simple governance and improved water quality," said John Picerne, Founder at Corvias. "With our partners in Prince George's County, we successfully implemented and completed a large scale CBP3 model solution to stormwater management, turning a regulatory mandate and fiscal burden into a program that positively impacts the health of the local watersheds and Chesapeake Bay and also improves the community with greater socio-economic impact."

The CWP developed and implemented a turnkey stormwater management program that proved the ability to achieve regulatory compliance requirements, and create greater community buy-in and education along with long-term local economic benefits for residents and local small minority disadvantaged businesses. The recently released report shows the Clean Water Partnership has accomplished those objectives and completed the initial pilot retrofitting 2,000 acres using greater than 87% local minority and target class County businesses, and saving the County more than 40% compared to traditional, non-bundled procurements.

"This unique partnership has allowed Corvias to aggregate the County's stormwater challenges into a performance-based, investable program," said Greg Cannito, Partnership Innovator for Corvias. "This partnership demonstrates how to meet regulatory compliance, while reducing the burden on local government budgets, creating economic growth, and fostering better local development practices."

"The value of this partnership is multifaceted," said Keisha Brown, Partnership Liaison for Corvias. "From the increase of the community's awareness of adverse effects of polluted runoff to the growth of small businesses focused on green infrastructure, the EPA has validated the Clean Water Partnership as a best practice for municipalities looking to make significant environmental improvements."

The CWP has received national recognition from the White House and EPA. The CWP has also been highlighted as a successful and innovative approach to better infrastructure from the Natural Resource Defense Council (NRDC). As a result of this success and recognition of the initial pilot program, many jurisdictions in the State and around the country are looking at the CWP and its results as a model to address their specific needs and requirements to tackle aging infrastructure. Universities are also paying close attention to the record breaking success of the program and have used the CWP as a case study for their student projects.
