The use of GRP pipe in water and wastewater systems

GRP, Glass reinforced plastic has been used as a pipe material in the industrial sector since the 1950’s and in wastewater treatment plants since the 1960’s but is still considered a “new” pipe material. This paper covers the history, design, longevity and installation of GRP pipes in water and wastewater networks. Including the presentation of studies into the longevity of GRP pipe in wastewater applications. Where does GRP pipe fit in the range of pipe materials available to network engineers and how do we compare one material against another?
