Emptying silt sumps

Is the silt sump at your detached house or free-time residencies full? Request emptying of the silt sump so that we can make sure together that the sewerage system and silt sump remain in operating condition.

Emptying frequencies of septic tanks and cesspools

  • Cesspools must be emptied as needed but at least once every three (3) years.
  • Septic tanks or the silt containers of small sewage treatment plants must be emptied at least once a year.
  • The septic tanks in the wastewater systems of free-time residencies with a water closet or the silt containers of small sewage treatment plants must be emptied of sludge at least once a year.
  • If only washing water is channelled into the septic tank of a free-time residencies´ wastewater system or the silt container of a small sewage treatment plant, the septic tank or silt container must be emptied at least every two (2) years.

You can apply to the municipal waste management authority for less frequent emptying for a justified reason. For more information on the legal provisions concerning the emptying of silt sumps, see the waste management regulations of the shareholders of Loimi-Hämeen Jätehuolto Oy.
