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

• The preservation of sanitary protection zones protects drinking water sources and the natural environment, positively affecting biodiversity in and around Lake Ülemiste.
• Using thermal energy produced from biogas that has been generated through sewage sludge fermentation reduces our ecological footprint and dependence on heat produced from non-renewable sources.
• Construction waste has low reuse potential, is bulky, and causes damage to soil.
• Using electric power contaminates the environment, causes air pollution, and accelerates the depletion of fossil fuels.
• Water extraction and treatment involve energy and chemical costs and environmental impacts.
• Increased own consumption of water is accompanied by a greater need for water treatment, which involves higher resource usage and environmental impacts.
• The use of chlorine in water treatment involves a risk of leakage and environmental pollution.
• Providing compliant clean drinking water to consumers enables them to choose tap water over bottled water, which reduces impacts related to the use of disposable plastic bottles.
• Discharging wastewater into the sea can cause harmful pollutants to enter the marine environment.
• By reusing and recycling sewage sludge, we reduce the amount of waste that is deposited in landfills.
• Discharging partially treated and untreated sewage into the environment pollutes the environment and has a negative impact on the marine environment and marine life.
