Project Overview
Dammam Sewer Network Rehabilitation
Beta Green Plastic Factory supplied PVC gravity drain pipes for the rehabilitation and expansion of the central sewer network across 8 districts of Dammam. The project replaced aged asbestos cement and concrete pipes with modern PVC systems offering superior flow performance and 50-year design life. Pipe sizes ranged from DN200 to DN800, manufactured to BS EN 1401 and ISO 4435 standards.
