Neva Bay
To address the problem of water pollution, the city's government adopted a plan to upgrade the city's sewage system to limit the amount of untreated wastewater release to less than 0.1%. The measures being taken seem to be quite efficient – after the launch of the modern long-awaited South-West Wastewater Treatment Plant in 2006 the amount of biological and phosphate waste is expected to be lowered by 60% and 25%, respectively. Over 30 water purification installations are placed around the complex, a part of a larger effort to clean the water in Neva Bay.
