It is important it is to have a good drainage system as the subsoil is very delicate. Both industrial and civil engineering projects require drainage in areas of water ingress that cause severe damage. Identifying groundwater and sewage HDPE pipes is critical to building an effective drainage system. They require an unpressurized tube made by sequential coextrusion of two layers. The inner layer is smooth and the outer layer is wavy. HDPE pipes are ideal for water and wastewater applications. High Density Polyethylene or HDPE pipes are suitable for low pressure and gravity sewage such as municipal and industrial sewage, storm and sanitary sewage. The smooth inner walls of HDPE corrugated sewer pipes provide excellent hydraulic efficiency. Because they are very imperforate holes in plastic pipes. By comparison, ductile cast iron pipe has a higher flow rate per metric head/mm bore.

• Highly resistant to hydrogen sulfide gas, water, other low concentrate acid found underwater ground.
• Lightweight and rigid which makes them easier to install and handle
• Better to withstand in cold weather installations whereas other pipes are prone to break or crack.
