What Kose Vesi | Aedes Web Solutions does

Kose Vesi (legal entity OÜ Kose Vesi, reg. 10917886) is a municipally owned water, wastewater and district-heating utility serving residential customers in Kose municipality, Harju County, Estonia. The company was formed through the July 2013 merger of OÜ Kose Vesi with U-M Soojus OÜ under Kose Vallavolikogu decision No. 203, consolidating water/sewage and district heating services into a single regulated utility, and expanded its service territory in June 2024 to include the Ardu and Habaja settlements following the dissolution of Sihtasutus Kõue Varahaldus.

Its core operations span three regulated revenue streams: (i) potable water production and distribution from drilled groundwater wells (Ordovician-Cambrian aquifer at ~160 m in Kose, Oru and Vardja; Ordovician aquifer at ~70 m elsewhere); (ii) sewage collection and biological treatment at the Kose wastewater treatment plant (4,500 IE / 650 m³/day capacity, treating ~250 m³/day on average via activated sludge, ~48-hour retention, with remote monitoring and standby power integration); and (iii) district heating from wood-pellet boilers supplied through a reconstructed pipeline network to Kose, Kose-Uuemõisa, Ravila and (from Feb 2026) Ardu. Technology stack includes Kamstrup Multical 21 ultrasonic remote-read smart meters (full rollout by end-2017, 85% KIK-funded), a SCADA-style wastewater remote-monitoring system, and GDPR-compliant customer data processing. All prices are regulated by Konkurentsiamet (Estonian Competition Authority): water at 1.73 EUR/m³, sewage at 3.31 EUR/m³, heating at 108.56 EUR/MWh (Kose area) or 69.38 EUR/MWh (Ardu from Feb 2026).

The business model is a regulated municipal utility: 100% direct-to-consumer delivery through owned infrastructure within an exclusive service territory, billed monthly on usage (per m³ or per MWh) plus one-time service-work fees. Customers are residential households (and small businesses) across Kose, Kose-Uuemõisa, Ravila, Ardu, Habaja, Oru, Palvere, Vardja, Kuivajõe and Karla, with no alternative in-territory providers. The owner is Kose Vald (Kose Municipality); the company has no external equity investors, no public listing, and no M&A track record beyond the 2013 merger and 2024 service-territory absorption. Customer acquisition is purely via municipal mandate; capex is funded ~50–85% by EU Cohesion Fund grants administered via SA Keskkonnainvesteeringute Keskus (KIK), with the remainder split between Kose vald and OÜ Kose Vesi. Marketing is limited to the company website, EVEL-coordinated national water-awareness campaigns and WWTP open days — no paid acquisition motion exists, consistent with its monopoly-utility status.

• AS Tallinna Vesi: Estonia's largest water and wastewater utility, also listed on the Tallinn Stock Exchange. Provides the closest analogue to Kose Vesi's business model (regulated water/sewage tariffs) but at scale serving the Tallinn region. Comparable as it operates under the same Konkurentsiamet regulatory framework and Estonian EU-cohesion funding mechanism.
• Utilitas: Estonia's largest privately-held district heating operator, providing centralised heating to households and businesses across multiple Estonian municipalities using biomass and other fuels. Directly comparable to Kose Vesi's wood-pellet district heating business and multi-utility operating model.
• AS Pärnu Vesi: Water and wastewater utility serving Pärnu, Estonia's fourth-largest city. Operates under the same Estonian regulatory framework as Kose Vesi, with comparable municipal-utility ownership and EU co-financed infrastructure projects. Direct business-model peer in Estonian water utility landscape.
• AS Kuressaare Veevärk: Water and wastewater utility serving Kuressaare on Saaremaa island. Small-to-medium Estonian municipal water utility comparable in scale and operating model to Kose Vesi, serving a similarly sized rural/small-town population.
• AS Tartu Veevärk: Water utility serving Tartu, Estonia's second-largest city. Direct Estonian water utility peer with similar municipal utility operating model, regulated pricing, and EU-funded infrastructure investments. Comparable regional-scale water and wastewater operations.

Comparable on the regulated district-heating business model and renewable-fuel (biomass/pellet) heat generation that mirrors Kose Vesi's wood-pellet boiler stack.
• Enefit (Eesti Energia): Estonia's state-owned national energy conglomerate. Operates district heating alongside electricity generation and distribution. Comparable on the regulated thermal-energy side of Kose Vesi's business, providing a benchmark for how district heating scales in Estonia.
• Helsinki Region Environmental Services Authority (HSY): Municipal authority providing water supply, wastewater treatment, and waste management services to the Helsinki metropolitan area. Comparable as a multi-utility municipal entity operating regulated water and wastewater services across multiple municipalities, including EU-funded infrastructure investment.
