What is Stormwater Management?

Whenever there is land development, e.g. houses, roads, parking spaces, commercial buildings, hotels, supermarkets, etc., on which it rains heavily, there will be a quantity of storm water than needs managing, which previously would have been absorbed into the ground.

To begin with, this is a problem because the water does not infiltrate into the soil so the water table is lowered. Secondly, if the water has nowhere to drain to (or drain to fast enough), it will flood the surface, potentially causing water damage to the property or surrounding land.  Thirdly, if a mains drainage network exists which this storm water can be connected to, there is a possibility for that to become overwhelmed with the additional storm water and flood either the property/land in the immediate vicinity, or a property downstream. Finally, climate change will aggravate the problem by increasing the quantity of water discharged during a storm, thereby making the problem worse for future land development.

For this reason, there has been a marked increase in demand for storm water management systems on all developments in recent years.As one of several solutions for storm water management tanks, crates/geocellular systems are a popular choice for surface water management.
