OSD on site retention / detention
The managed release of stormwater from a property into the municipal drainage network infrastructure during heavy rainstorm events is managed by the on-site retention-detention devices that have been configured for one of two purposes:
- Retention is a design to retain usually a fixed amount of rainwater collection or stormwater whereas a detention design will hold back the peak flows (to the capacity of the storage available) and allow a controlled slow release of the peak flow to public drainage infrastructure. The purpose is often to assist the capacity of public drainage infrastructure, by extending out the time the drainage infrastructure needs to remove discharge stormwater for a site
- Detention retains a certain amount of the storage volume for later use on the property which also has the effect of reducing the quantity of stormwater discharged by the storage amount but is not time offset.
These devices are commonly known as an OSD.
The SPARKLE | WATER OSD can also be configurerd as a multi-function device with options for filtering the stormwater before passing through the storage device and causing blockage of the orifice plate outlet.
An above ground retention / detention storage tank normally only handles rainwater collected from a roof catchment, whereas an inground storage tank can receive surfacewater and roofwater to manage the majority of run-off water of a site controlling the volume of stormwater release to large infrastructure drains or waterways.
The nominal size of the orifice is nominally 48mm for a suburban property.
The capability of the SPARKLE | WATER OSD and attachments used are designed to avoid confined space entry for cleaning of organics and also act as a silt pit that can be accessed and maintained from ground level.
The configuration of an OSD can be specified to include typical outlet connections to standards design requirement if confirmed at time of order.
