Unfortunately, our sludge collection forms exist only in Finnish and Swedish at the moment. Please don’t hesitate to contact customer service if you need assistance.

Sludge-tank emptying at regular intervals or by order

Permanent homes and holiday homes with flush toilets: Septic tanks and small sewage treatment plants must be emptied at least once a year. Holiday homes with only a dry toilet: Septic tanks must be emptied at least once every two years.

Cesspools can be emptied either at regular intervals or only by the customer’s order. Keep an eye on the amount of sludge in the cesspol, in order to be able to order a timely collection date.

Regular emptying is only conducted during working days. If the temperature drops below -15 °C emptying can not be carried out, in which case emptying times will be delayed.

How to arrange emptying

An order for sludge emptying is placed with either our customer service, or via the e-service. Make an appointment for emptying at least five weekdays in advance, preferrably even earlier if possible. This way routes can be planned in time and sludge tanks emptied systematically.

If an emptying is ordered for the same day, a transportation fee for express emptying will be applied.

NB! On Norrskata, emptying is only conducted on odd weeks. The order must be placed on Thursday of the previous even week, at the latest.

How to cancel a regular emptying date

If not enough sludge for collection has accumulated in your septic tank, the current year’s emptying date can be cancelled by filling out the cancellation form and delivering it to the local waste management committee. Our customer service will assist, if needed.

The cancellation must be made at least 4 weeks in advance of the planned regular emptying date. The cancellation concerns only the ongoing year’s emtying date.
