OSD tanks control the flow of stormwater from the roof to the local stormwater system. Buildings with large roof surface areas capture a large volume of rainwater that may overwhelm the local stormwater drainage system if allowed to flow freely. OSD tanks detain the water and provide a controlled release to prevent stormwater surges. Many council approvals for large buildings require the installation of OSD or DCP systems. However they can only be designed by a suitably qualified hydraulic engineer. Often it is left to the plumber to interpret the engineer’s design and build an OSD system from stormwater components such as pits and water tanks. To do this on site can be tedious and often not cost effective. SWT Pits and Grates will take your hydraulic drawings and construct a stormwater management system to your engineer’s design. The system can include an OSD tank and DCP complete with orifice plates, trash screens and with inlets and overflows in the correct position. Sometimes the OSD,canbe combined with the rainwater reuse tank to save cost. The delivery truck will crane the tank(s) and DCP into position. Once on site the system is ready to connect immediately. SWT Pits and Grates provides clear installation drawings to ensure your stormwater system is installed properly. A sample of stormwater management systems previously supplied by SWT Pits and Grates are available on the ‘Downloads’ page. |
