Sulkavuori Central Wastewater Treatment Plant

Construction of the Sulkavuori Central Wastewater Treatment Plant began in 2018 and is expected to be commissioned in 2024. The Sulkavuori Central Wastewater Treatment Plant will be excavated in rock to create stale conditions for the operation of the treatment plant, so that treatment processes are not disturbed or slowed down due to weather variations.

The planned Central Wastewater Treatment Plant uses the latest treatment technologies in order to keep the discharge load on the lake to a minimum. The activated sludge process is supplemented by sand filtration and UV disinfection. The treated wastewater is led to Lake Pyhäjärvi by means of a tunnel excavated in the bedrock and a discharge pipe.

The progress of the excavation of the Sulkavuori Central Wastewater Treatment Plant can be monitored through the environmental monitoring system, EMO (Environmental Monitoring Online), developed by Kalliotekniikka Consulting Engineers Oy.

In the design of the Sulkavuori Central Wastewater Treatment Plant, special attention has been paid to a possible future expansion.
