Design
The Skeletank Mini Flow Control Chamber is specifically designed for use within a Skeletank attenuation system. The standard 11mm diameter orifice, protected by a removable filter, allows for surface water runoff to be restricted to a flow rate of 0.2l/s, preferably within the curtilage of each plot to suit the site layout.
Orifices to suit higher flow rates of 0.4l/s and 0.6l/s are available should the drainage system need to accommodate more than one property for genuine design reasons.
SELH 03001 Skeletank Mini Flow Control Chamber
Specification
Filters are removable to allow for cleaning and/or replacement. A specialised tool is required to facilitate removal and it is essential that filters are fixed back into position before replacing the filter tube.
Each chamber has a 200mm deep sump to accommodate the deposition of any suspended solids remaining in the runoff which has passed through the Skeletank RWP Filter Chambers positioned on the downpipes.
The chamber spigots are sized to fit standard 110mm diameter underground push-fit PVC-u drainage sockets.
