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.
