Real estate specific wastewater management

A real-estate specific wastewater treatment system must fulfil the treatment power requirements set out in the in the Environmental Protection Act.

The wastewaters must be treated so that they do not cause any health or environmental hazards. Outside the operational area of the water management plant, wastewaters are usually processed real estate specifically.

Each piece of real estate must have a written review of the treatment system of the wastewaters produced by the real estate. The requirements set for this review have been presented in the in the Environmental Protection Act and in the Government Decree on Treating Domestic Wastewater in Areas Outside Sewer Networks.

Building or changing a wastewater system requires a actionpermit, which is applied for from the Building Control. A plan concerning the wastewater system should be attached to this permit application, which must fulfil the criteria presented in the Government Decree on Treating Domestic Wastewater in Areas Outside Sewer Networks.

The plan of the wastewater system must be compiled by a qualified planner. The Environment services will give usually the Building Control a statement concerning the plan. The wastewater system must be used and maintained in accordance with the manufacturer's instructions and legislation so that it works as planned and that the set treatment requirements for wastewaters are met.

The wastewater system must have up-to-date user and maintenance instructions. These must be kept on the premises and be shown to the control authorities upon request.
