AlexRenew’s $615 million RiverRenew project aims to slash overflows and bacteria discharges
Summary
AlexRenew told the Commission its $615 million RiverRenew tunnel will cut overflow events to fewer than four per year and reduce bacteria in discharges by 80–99%; financing will rely on WIFIA loans, state revolving funds and municipal green bonds.
Justin Carl, General Manager and CEO of AlexRenew, described RiverRenew — a tunnel beneath Old Town Alexandria that intercepts combined sewer overflows and routes flows to the AlexRenew treatment plant. Carl said the $615 million project "will decrease overflow events to fewer than 4 per year and reduce bacteria in discharges by 80-99%," and noted the tunnel and related upgrades are nearing completion.
Carl explained AlexRenew has used EPA WIFIA loans and the Virginia Clean Water Revolving Loan Fund to help finance past upgrades and that limited state revolving funds will push the utility to rely more on municipal green bonds, while retaining access to low interest rates because of its strong bond rating. Members toured the plant and an underground pumping station tied to the tunnel project after the briefing.
