A common problem in many parts of the world is sewage odour rising from sewage pipe systems. WaStop® stops odour from rising without interrupting flow.
WaStop® DN100mm – Oslo, NORWAY
Torg Street in Olso has had an ongoing and longstanding problem with sewage odors from the sewer drains. To stop this problem 52 WaStop® DN 100 have been installed. These check valves now protect cable culverts from water during torrential rainfall and the odor is stopped from being forced up to the street.
The sewage odor is not missed by either the shop owners affected or Olso Council!
WaStop® DN790 – Stockholm, SWEDEN
The discharge of odours or aggressive gases from sewage systems can be a major problem in built up areas. By installing a WaStop® in the system discharge can be stopped, or directed to a less sensitive area. By installing WaStop® insects and small animals are stopped from entering storm and waste water drains.
This check valve were installed in Stockholm to prevent odour coming up from the sewege system and affect the nearby houses. The smell that was a big problem before is now gone.
WaStop® DN110 PVC – Jizan, SAUDI ARABIA
CSO England undertook an odour control contract in Jizan, Saudi Arabia. CSO provided odour control (based on their Terminodour system), to an underground sewage reception channel. The channel has 18 tanker filling points, which tankers discharge sewage into. The Wastop valves form part of the new tanker discharge arrangement. The tanker discharge connections comprise a Bauer coupling (which allows the tanker to connect to) and a Wastop valve which allows flow in the normal direction, but prevents odour emission from the channel to atmosphere.
The Wastop valve acts to prevent odour from being release from the storage channel to atmosphere from the tanker filling points, during periods of non filling. 38 WaStop DN110 PVC were installed successfully.
