Wastewater Treatment Plant Liners
Wastewater treatment plant (WWTP) liners protect the environment by preventing wastewater from contaminating groundwater. 36 mil Polypropylene and 60 mil HDPE are popular choices for WWTP liners. Both are compatible with wastewater and have excellent physical properties.
Polypropylene has an advantage because the panels are prefabricated in a controlled environment. This minimizes field seams, which are more likely to leak because of the presence of dirt and moisture in the seam.
