The most significant environmental aspects and impacts of AS Tallinna Vesi include:

  • Maintaining of sanitary protection areas protects drinking water sources and the natural environment, supporting the improvement of biodiversity in the surroundings of Lake Ülemiste and in the lake.
  • Using the heat energy produced on site from biogas, which is a residue of the sludge digestion process, reduces the ecological footprint and dependence on the heat produced from non-renewable resources.
  • Construction waste has a low potential of being reused and is bulky, causing soil damage.
  • Using electrical energy pollutes the environment, causes ambient pollution and accelerates the exhaustion of fossil fuels.
  • Water extraction and treatment involve energy and chemical consumption and the resulting environmental impacts.
  • The use of chlorine in water treatment process involves a risk of leakage and environmental pollution.
  • Supplying compliant drinking water to consumers creates the opportunity to choose tap water over bottled water, thus reducing the impact from the use of disposable plastic bottles.
  • The discharge of treated effluent into the sea may result in the release of pollutants which have a negative impact on the marine environment.
  • By reusing and recycling the sewerage sludge we reduce the amount of waste to be landfilled.
  • Discharge of untreated wastewater into the environment pollutes the environment and has a negative impact on the marine life and -environment.
