What Strantum does
Strantum OÜ is a municipal utility company headquartered in Tabasalu, Estonia, wholly owned by Harku vald (Harku municipality). It delivers an integrated set of essential public services within the municipality's territory, including potable water supply, sewage collection, district heating, property maintenance, and road maintenance. The company's physical asset base comprises a district heating network of approximately 4.82 km serving 76-77 buildings in Tabasalu, water and sewage networks expanded by 4,000+ connection points over the last decade, 360 km of maintained roads, and roughly 1,000,000 m² of maintained green areas. It serves more than 5,000 households, municipal buildings (schools, sports complex, library), and other public infrastructure within Harku municipality.
The company's underlying technology is conventional utility engineering infrastructure — piped water/sewage networks, district heating distribution, road grading equipment, and grounds maintenance machinery — rather than software or digital platforms. There are no indications of proprietary technology, software products, or platform architecture. Approximately 50 million EUR has been deployed into water and sewage infrastructure over the past decade, reflecting an asset-heavy, capital-intensive operating model.
Strantum's revenue mechanics operate on three tracks: (1) regulated household tariffs for water (1.78 EUR/m³) and sewage (2.92 EUR/m³), approved by the Estonian Competition Authority; (2) district heating service fees for connected buildings; and (3) municipal contracts for property and road maintenance, with Harku vald as both owner and primary contractual counterparty. The 2020 partnership with SW Energia OÜ supports heat supply into the Tabasalu network. In 2025 the company was recognized as Estonia's Property Maintenance Company of the Year, validating its integrated service offering.
