Sustainable urban drainage systems (SuDS) are an increasingly important part of our green infrastructure. SuDS can take many forms, both above and below ground. Certain types of SuDS include planting, others include manufactured products. A functioning system is designed to manage and use rainwater close to where it falls, incorporating vegetation into a building has been shown to be the most effective means of control.

Examples of how Enrich products and services can use in SuDS for sites:

 

Green roof Substrates.

A vegetation layer on a roof surface has many benefi ts such as storm water management/attenuation, thermal retention properties, biodiversity enhancement, recreational use and aesthetic improvement, as well as meeting current planning regulations.

Bioretention Soils.

Collecting the runoff from buildings and diverting them to rain gardens to fi lter through Enrich specialised soil improves the quality of the water leaving the system, thereby alleviating the pressure on downstream water treatment facilities. Matching the size and rate of the flow is critical to success of a functioning bioretention area.

Urban Tree Soils.

Healthy trees have the ability to capture vast amounts of storm-water, provide evapotransporation, biodiversity and shade. Using Urban Tree Soils that have the correct balance of fertility, porosity and volume will create a better environment for trees to grow and function in the system.

Development of Soil.

Enrich will Identify and carry out specifi cation of soils onsite that could be used in SuDS. Enrich can engineer soils onsite, which can avoid unnecessary costs by removing soil off site only to import soils back.
