Septic tank or bio-treatment unit?
A septic tank is simpler and cheaper but needs an infiltration field and suits a smaller load. A bio-treatment unit purifies wastewater more thoroughly and is suitable when the ground or plot size doesn't allow an infiltration field.
We make the choice together: we look at the household size, ground conditions, groundwater level and plot constraints.
Who this service is for
- House owners outside the public sewerage area
- Owners of summer houses and cottages planning year-round use
- Property owners whose existing system is worn out
Installation step by step
We inspect the plot, assess the ground and groundwater level, and help choose a septic tank or bio-treatment unit with the right capacity. We then carry out the excavation, install the tank and infiltration field or infiltration system, connect it to the house's sewerage, and pressure test the system. Finally we backfill the trench and restore the ground.
Maintenance intervals and requirements
A septic tank or bio-treatment unit needs regular emptying and checking so the system doesn't block up or start leaking. Frequency depends on the tank, household size and load — we set the exact schedule at the first inspection and can also agree on a regular maintenance visit.
Frequently asked questions
- How often does a septic tank need emptying?
- Usually 1–2 times a year, depending on the tank and household size.
- Do I need a design for installing a septic tank?
- Usually yes, depending on the local municipality's requirements and the plot's location — we help clarify what's needed in each specific case.
