Hämeenlinnan Seudun Vesi

What Hämeenlinnan Seudun Vesi does

Hämeenlinnan Seudun Vesi Oy (HS-Vesi) is a municipal water utility founded in 2001 and jointly owned by the Finnish municipalities of Hämeenlinna, Hattula, and Akaa. The company operates as a regulated, non-profit provider of drinking water supply and wastewater treatment services across a legally defined service area in the Kanta-Häme region of southern Finland. Under the Finnish Water Supply Act (Vesihuoltolaki), property owners within the service area are required to connect to HS-Vesi's networks, giving the company an exclusive franchise with a fully captive demand base. It supplies roughly 4.7 million m³ of drinking water and treats approximately 8.9 million m³ of wastewater annually, serving individual homeowners, businesses, property managers (isännöitsijät), and the construction sector for new connections.

HS-Vesi's core asset base is its physical infrastructure: 1,200 km of water supply network, 1,000 km of wastewater drainage network, 400 km of urban drainage network, and more than 350 pumping stations, supported by the Ahvenisto and Kylmälahti water treatment plants using chloramine disinfection. Customer-facing digital tools include the Vesitili online account portal for meter reading submission, an interactive Häiriökartta (disturbance map) for real-time service status, and an SMS alert system for outage notifications. In April 2025 the company launched a pilot for remote-readable water meters, and it operates a wholly-owned subsidiary, HS-Hulevesipalvelut Oy, for stormwater services.

The business model is straightforward: HS-Vesi finances all operations through recurring water supply fees and wastewater treatment fees collected from connected properties, with no financial gain objective. All revenues are reinvested into infrastructure maintenance and development. Pricing follows published rate schedules (hinnastot) with annual billing, supplemented by one-off connection fees for new construction and elevated wastewater charges (korotettu jätevesimaksu) in certain circumstances. The go-to-market motion is direct-to-customer, supported by a website, customer magazine (Vesi-lehti), SMS communications, and a LinkedIn presence for employer branding. In 2025 the company reported consolidated group revenue of approximately €27.7 million and returned to a €0.527M profit after two prior loss years.
