Terrain Pleura

The unique design of the Terrain Pleura® system, when used in conjunction with the Terrain above ground drainage system, provides an alternative ventilation solution for Terrain pipe fittings that prevents the loss of water trap seals. Suitable for use in both residential and commercial, high-rise and super high-rise buildings, Terrain Pleura® is already widely used across the Middle East in installations like Ferrari World and the Yas Marina Hotel in Abu Dhabi.


Simple and effective, the Terrain Pleura® system has been engineered to balance the internal air within Terrain over ground drainage systems, protecting the water trap seals found in sanitation appliances and reducing the unpleasant drainage odors frequently found in buildings. The Terrain Pleura® system also has the ability to considerably reduce the number of drainage pipe roof penetrations, making for a much simpler installation.


We have developed a range of drainage systems to provide the most suitable solution for every project and budget. Find out more about our other Terrain solutions, Terrain Hydromax and Terrain Rainwater Outlet.
