What Sciens Water buys
Sciens Water is the water investing arm of Sciens, a New York alternative investment manager that dates to 1994. It was set up in 2018 to invest only in the U.S. water sector, through the Sciens Water Opportunities Fund, and its history page says a second fund is launching in 2026. It backs both hard infrastructure, such as regulated water and sewer utilities, and operating companies across the water chain: treatment and reuse, pipes and storage, filtration, and monitoring technology. The fund mostly takes control positions, with a few minority stakes, and says it has put about $1.7 billion into U.S. water infrastructure since 2018.
Sciens Water does not publish revenue or EBITDA limits. Its two main platforms today are Central States Water Resources, which buys small, struggling water and sewer systems and brings them into compliance, and Veyra, a wastewater treatment and filtration group that made three acquisitions between May and August 2026. A smaller water company is most likely to meet Sciens as an add-on to one of those two.

Greymont’s take
How Sciens Water fits a seller
Sciens Water suits owners of water and wastewater businesses who want a buyer that does nothing else. Two groups fit best. Owners of small private water or sewer systems, especially ones facing compliance or repair costs, match the Central States Water Resources model of buying and fixing such systems. Owners of treatment, filtration, reuse or water equipment companies match Veyra, which bought three businesses in four months in 2026.
Those deals suggest founders often keep a role: the Complete Filtration CEO kept a significant stake, and the AESINC founder stayed involved in running the business. Because Sciens mixes long-lived utility assets with operating companies it sells, as with CROM in 2025, an owner should ask which side of the platform the business would join, whether rolled equity sits in the current fund or the new one, and how long Sciens plans to hold it.
Questions owners ask
What kinds of water businesses does Sciens Water invest in?
Only U.S. water. Its portfolio spans regulated water and sewer utilities, wastewater treatment and reuse systems, filtration and desalination equipment, pay-as-you-go water infrastructure for cities and schools, and water monitoring technology.
Does Sciens Water buy small water and sewer systems?
Through Central States Water Resources, a St. Louis based utility it owns, which focuses on acquiring small systems that are out of compliance and upgrading them, as with its Arizona subsidiary's 2026 work on the Sunizona and Stoneman Lake systems.
Has Sciens Water sold any companies recently?
Yes. It sold CROM, a Gainesville, Florida builder and restorer of concrete water storage tanks, to Frontenac in February 2025, and its portfolio page also lists Sciens Water Digital Holdings, a remote monitoring software business, as realized in 2025.
