Installing a water tank on a slope introduces unique challenges. Without professional water management, gravity turns standard rain into high-velocity water runoff that can quickly undermine your tank’s base. On sloping properties, water could gain momentum, searching for the path of least resistance.
Our approach focuses on diverting water away from the foundation through engineered drainage solutions, ensuring your tank remains level even when the ground around it isn’t.
Effective water management starts at the roofline and must follow a planned path to a safe point of discharge. Rather than leaving drainage to chance, we look at the entire landscape to design a system that works with your property’s natural contours. This often involves the strategic creation of landscaped channels that interfere with overland flow before it can reach the tank and the installation of water drainage, like French drains or ag-pipes.
By managing groundwater and routing overflow to a stabilised area, we prevent the soil beneath your tank from becoming waterlogged, which is the primary cause of foundation shifting and structural instability.
The efficiency of your tank filling is determined by the integrity of your inlet plumbing and how well it handles the runoff water cycle. We optimise your pipework to ensure maximum flow during heavy NSW downpours, reducing the risk of back-pressure that can lead to gutter damage or wasted water.
Our water management services include first-flush diverters, which ensure that the initial, debris-heavy water runoff is discarded. This leaves only the cleanest possible supply for your water tank filling, protecting your pumps and ensuring your storage reaches its maximum capacity with high-quality water every time it rains.
Prevents piping (underground erosion) that causes tanks to tilt or crack.
Ensures your water drainage meets local NSW council requirements, preventing disputes with downhill neighbours.
By managing the runoff water cycle effectively, you reduce the amount of organic silt and debris entering your storage.
Professional site grading means you don’t have to worry when the East Coast Low storm hits.
This is usually caused by poor water drainage, where water has pooled against one side of the slab, softening the soil and causing subsidence.
Yes, but it requires a cut-and-fill platform or a retaining wall. Our water management experts can advise on the best structural approach for your specific grade.
A dedicated overflow pipe must be installed. If this isn’t managed correctly, the excess water will spill directly onto the base, causing immediate erosion. We always pipe overflow away to a safe area.
