Treatment of slurry generated by residential activities

The treatment of slurry generated by residential activities is governed by waste management regulations. Property owners must arrange the collection of slurry generated at their property (both septic tanks and cesspits).

To join the waste management service, contact a waste management company that has been approved for the waste management registry maintained by the Centre for Economic Development, Transport and the Environment and agree on the emptying of your tank. The waste company is responsible for delivering the slurry for appropriate treatment at a reception station.

You can make enquiries on waste companies by phone on +358 3 871 1710, or by email to asiakaspalvelu@phj.fi. Regional Centres for Economic Development, Transport and the Environment maintain a registry of waste transport companies.
