Surface water management begins with an assessment of the hydrological demands of the project. The rainfall and topography of the landscape then determines the surface water solution.

As the available land in cities becomes increasingly developed, large surface areas are being covered with impermeable pavements. This leads to an increase in volume of water runoff on the stormwater system and to receiving waterways which ultimately impacts the environment. Government departments regulate stormwater quality and detention. Policies and guidelines are put into place supporting innovative solutions to conserve, retain and reuse our most valuable water resource.

Sustainable surface water management is an integral part of the planning process. Urban designers need to consider managing the quantity as well as the quality of water that is discharged after it has been captured and stored. Plastic geocellular systems have been used for a number of years and are a widely accepted method of creating infiltration and detention systems. When properly integrated, they can enable stormwater discharge at a slower more natural rate. This protects the stormwater system, prevents erosion and increased flow to receiving waters. Pollutants, debris and sediment can be removed from the water so it can be harvested for reuse in parklands, sports fields, commercial agriculture and residential gardens.
