Definition
A septic tank collects wastewater from the building where there is no public sewer, emptied periodically by tanker or with a soakaway as the rules allow. Its capacity is designed for the number of users.
Why it matters on a project
Poor construction causes smells and leaks that pollute the soil and the water tank. When a sewer arrives later, the building is connected as the authority requires.
Measurement and pricing
Excavation and concrete in cubic metres or a lump sum per tank, connecting pipes per linear metre.
Common mistake
Building the septic tank close to the water tank or a neighbour's foundations without the required distances.
Frequently asked questions
Does a septic tank need design?
Yes, its size, type and location follow the number of users and municipal rules.
What happens when the sewer arrives?
The building connects to it per the authority's rules, and the old tank is filled or removed.
