Pelican Orifice Plate
House builders and developers are looking for better SuDS design and one of the simplest ways to optimise the sustainability, is to install localised or plot attenuation systems on single dwellings and small developments, rather than install large, extensive attenuation systems downstream of the development.
Most of the attenuation systems currently being installed, are crate/cellular type systems and the concern is and continues to be the long term sustainability of these type of attenuation systems.
Pelican Systems have been designed to be fully sustainable, offering a minimum design life of 60 years, with very little maintenance required. They are comparatively quick and simple to install and unlike crate/cellular attenuation systems, Pelican Systems require no membranes or geotextile wraps and can be installed in reclaimed material, offering both ‘piece of mind’ and significant savings on overall installation costs, compared to crate/cellular systems.
The Pelican Packaged System will consist of:
- High performance SILTBLOK – Silt Management System, sited upstream of the tank, for connection of downpipes, ground water gullys or channel
- High Strength twinwall Pelican Attenuation Tank
- Oriflo – Orifice plate flow control units, complete with orifice plate manufactured to your specific design. The Oriflo will have a 160mm EN 1401 pipework connection to tank and then a choice of 110 or 160mm EN 1401 discharge pipe connections.
