The company operates through two main treatment facilities: the Ülemiste Water Treatment Plant (which uses ozonation for drinking water purification and is undergoing an €11.8M expansion with Nordecon AS) and the Paljassaare Wastewater Treatment Plant (which uses AI-optimized processes and biogas cogeneration to produce all heat and over half of electricity for its operations, while treating approximately 38-40% of Estonia's total household wastewater).
