How much water the systems need to manage
The drainage and rainwater systems' area of influence receives an average of
138,000 litres
The estimate is based on rainfall over the past ten years within this building's drainage and rainwater systems' area of influence, covering approximately 219 m². The calculation includes the building footprint and the surrounding area.
Where does all this water go on the property? This volume of water should be routed safely away from the building's foundations. Ground slopes direct surface water, the rainwater system carries roof runoff away and the perimeter drains collect water accumulating in the soil around the foundations.

Findings from the property's elevation differences
How does water move across the property?
We examined the property's elevation differences to assess where surface water is most likely to come from and where it naturally flows next.
- Natural drainage direction
- Towards north
- Ground slope
- Does not slope towards the building
- Gravity drainage
- Appears feasible
This estimate is based on ground elevation differences. The final discharge point, pipe falls and controlled routing of water are verified before installation.

When water flows the right way, home can feel like home
Working perimeter drainage, a properly designed stormwater system and correct ground grading carry water away from the building. Good moisture management is almost invisible in daily life. That is exactly how it should be.
