Drainage and sewer networks operate under demanding conditions: soil loads, vehicle traffic and continuous flow of wastewater or stormwater. PVC pipes and double-wall corrugated pipes offer high ring stiffness, tight joints and a smooth inner surface that limits deposits.
The choice of stiffness class (SN) depends on installation depth and loads, while correct bedding and gradient ensure a self-cleaning flow.
REPPAS S.A. covers sewerage projects with a full range of pipes and fittings, from domestic connections to public networks.
