SuDS & Attenuation Tanks
SuDS (Sustainable urban drainage systems) is the collective term used for a water management system that controls the rate and direction of rainwater on a site or land before it enters a mains drainage system.
An undeveloped open space such as a grassed field will retain and hold surface water much longer than the same space or field if it was covered in houses, roads and paving or tarmac. A well designed SuDS system should hold back surface water run off at the same level when compared to the space before it was developed.

Geocellular Storage systems
These are more commonly known as attenuation tanks. These are usually a modular crated system that is wrapped in a high performance HDPE membrane (High-density polyethylene) which in turn is wrapped in protection fleece and is buried in the ground. These tanks generally take the surface water from a development and then control the rate at which the water exits the tank and into the mains drainage system.
Ponds and Basins
There are various ponds and retention basins that are used in developments, these are generally used for the same principles as an attenuation tank, but can also be used for managing surface water pollutants before it enters the mains drainage system, a good example would be the planting of reed beds to control hydrocarbons such as petrol and diesel.
Ponds and retention basins can be lined using HDPE membranes and GCL membranes (Geosynthetic Clay Liner) depending on the requirements of the site.
