Stormwater Management
The management of rainfall and the subsequent Storm Water is of paramount importance for many reasons – to limit the potential for localised flooding; to minimise the potential for erosion of and damage to property; to ensure that public access areas remain safe; to control the direction and magnitude of flow to deliberate locations, to manage debris and potential contaminants from surface runoff, and the like.
In addition, and to provide greater environmental resilience, the storage, harvesting and re-use of storm water is a high priority for Authorities in all areas.
To support these needs, RA Smith has extensive experience in the successful delivery of Storm Water management projects which have included:
- Installation of primary trunk carrier drains, pits and culverts to transport the collected flows;
- Installation of subsidiary inter-connecting storm water drainage networks to manage local collection and discharge during rainfall events;
- On-site Detention structures to capture rainfall within a prescribed location (i.e., residential sub-division) to then allow controlled discharge over time. This helps Authorities manage flows during rain events to mitigate flood risks;
- Installation of Gross Pollutant Traps – tank-like devices designed to capture and separate contaminants such as fuels and oils from the storm water run-off to reduce the risk of pollution of the water courses into which storm water will often be discharged;
- Debris containment structures such as grates and weir walls which are constructed to interrupt flows and allow debris within the storm water run-off (tree branches, garbage, etc.) to be retained for subsequent removal;
- Localised or more widespread re-use systems such as irrigation management from on-site detention storages.
Multiple projects successfully completed demonstrate RA Smith’s capability to provide storm water management services to Clients, and demonstrate our commitment to improving storm water management, and so improving safety for the public within the built environment during significant rain events.
