CREW raises $25M to scale wastewater tech that cuts costs and carbon

What's the deal? CREW, a wastewater treatment optimisation startup, has raised $25M in funding to scale its technology that helps treatment plants run more efficiently while reducing carbon emissions. The company's platform optimises existing wastewater infrastructure, cutting operational costs and removing carbon from the treatment process.

Why now? Wastewater treatment is a significant and often overlooked source of greenhouse gas emissions. As municipalities and utilities face pressure to meet climate targets while keeping costs down, solutions that address both problems simultaneously are in high demand. Ageing water infrastructure across the US and Europe also creates urgency for upgrades that don't require costly rebuilds.

What could go wrong? Selling to water utilities and municipal governments is notoriously slow. Long procurement cycles, regulatory hurdles, and risk-averse buyers can stretch sales timelines and burn cash. CREW will need to prove its technology delivers measurable savings at scale to win over cautious public-sector customers.

The signal: CREW's $25 million raise positions it in the "early growth" stage, according to Dealroom, suggesting investor confidence that its retrofit-first approach has moved beyond proof of concept. With the wastewater sector responsible for an estimated 1.6% of global greenhouse gas emissions, the round underscores a growing appetite for climate tech that decarbonises essential but overlooked public infrastructure without requiring municipalities to rip and replace ageing systems.
