Certification of pumps-as-turbines

Rentricity Inc and the Cornell Pump Company have marked a major milestone with the certification of 22 pumps-as-turbines (PATs) models for energy recovery applications within solid pipe water infrastructure, also known as in-conduit hydropower.

The two companies have worked together for over 10 years on equipment to meet the certification requirements for NSF/ANSI/CAN 61: Drinking Water System Components – Health Effects and NSF/ANSI/CAN 372: Drinking Water System Components - Lead Content. These drinking water industry standards establish minimum health effect requirements for the chemical contaminants and impurities indirectly imparted into drinking water from products, components and materials used in drinking water systems.

The Water Quality Association (WQA) has recently certified the turbines

Only the certified turbines will display WQA's Gold Seal logo to indicate compliance to NSF/ANSI/CAN 61 & 372 standards, which are required by US state regulators for city drinking water and industrial food and beverage applications. These PATs use specialized alloys and procedures to assure certification with appropriate seals and documentation for state regulators.

The NSF/ANSI/CAN-61 & 372 certified turbine equipment is part of Rentricity’s Flow-to-Wire systems which convert flow and excess pressure into clean energy which can be used on-site or distributed to the electric grid. Rentricity has completed over 26 installations in North America for drinking and industrial water applications including food processing and irrigation contributing 1.3 million MW hours per year of clean energy offsets.

New York City-based Rentricity produces clean, renewable energy from in-conduit hydropower applications in drinking, agricultural irrigation and industrial water systems.

"The US market for In-conduit hydropower is at an inflection point with new applications and technology emerging yearly," said Frank Zammataro, CEO and co-founder of Rentricity.

“As the Infrastructure-Investment Jobs and Inflation Reduction Acts take hold, funding support to water operators for In-conduit hydropower applications will be a perfect sustainable, clean energy addition to any water pipeline project," says Marcus Davi, Vice President at Cornell Pump. "Marrying our turbine technology with Rentricity's proprietary control systems and certified conduit hydropower engineering expertise makes for a perfect application solution for water operators seeking to meet sustainability and ESG goals."
