About RWP
Completerainwatersystems
Our Proactive approach to climate change has led
RWP(UK)Ltd to develop the Clear-flow Siphonic rainwater
outlet.
Siphonic Rainwater systems where first developed in
Scandinavia and were introduced into the UK in the 1980s
and early 1990s when rainfall patterns were vastly different
to those we are currently experiencing.
Using our extensive knowledge of the Siphonic industry
RWP(UK)Ltd have developed a high flow capacity Siphonic
rainwater outlet - Clear-flow - which is capable of taking flows
up to 46 L/S per outlet (nearly twice the amount of some
earlier Siphonic outlets). The product has been developed to
work with all modern day construction methods and material
types, allowing the outlet and adjoining Siphonic system to
be used in virtually any new build or refurbishment.
As with all correctly specified and designed siphonic
systems, benefits are gained by the client in the reduction of
underground drainage r uns, simpler co-ordination - due to
the horizontal nature of the system - and considerably
reduced pipe sizes when compared to conventional gravity
installations. Due to the clear f low design of the outlet,
debris which could build up around the leaf guards or grills
causing blockage, are washed away through the Clear-flow
outlet and the high velocity Siphonic Pipe work below.
