SPARKLE Storm OSD 1000 litre 600x600 Class A Access Opening - keylock option

The SPARKLE range of integrated devices have been designed specifically to meet stringent regulatory and industry guidelines and are intended for water quality improvement and flow control. One Water Naturally now supply an easily installed onsite retention/detention device (OSD) for improved site stormwater management.

The SPARKLE OSD product are compact configurable device(s) that provides boundary stormwater management by withholding the rate of release from site drainage to public infrastructure. An OSD is a device that screens primary gross pollutants and then holds the bulk of the site stormwater collection by slowly releasing this retained stormwater through a engineered orifice calibrated for the hydraulic specifications. The device also has a high level overflow for peak intensity storms that may temporarily exceed the design specifications or system blockages that allows the safe overflow if required.

An optional external filter box with Maximesh screen is smarter thinking that can also be applied to the tank inlet to avoid tank blockages without needing access into the confined space of the tank for the continual maintenance needed for such systems.

The devices have as standard a 500 Kn top loading and side loading 2.1 Kn capability engineered using FEA analysis conforming to specifications of AS1546 standard starting with a polyethylene non-trafficable loading lockable lid. The tank or filter box can be supplied with upgraded heavy-duty access covers, grate or gatic with easy change-over installation.

Your SPARKLE product supplier can generally provide a client focused design specification supply, commissioning and maintenance service or referral to assist you for your needs.

The single dwelling scenario:
The single dwelling scenario consists of a 600 m2 allotment, a house with a roof area of 150 m2 and a paved surface area of 200 m2 (Figure 6).  Applying the OSD rules from the UPRCT On-Site Detention Handbook to this site results in a site storage volume of 28.2 m3, a 48 mm diameter orifice plate outlet to provide a permissible site discharge (PSD) of 0.0048 m3/s to the street drainage system. {ref: RAINWATER TANK OPTIONS FOR STORMWATER MANAGEMENT IN THE UPPER PARRAMATTA RIVER CATCHMENT, Peter J.
