Waste materials are disposed of through sewer pipes. Different types of sewer pipes are available in different sizes and materials. It is the primary function of sewer pipes to transport the sewage and wastewater produced by homes and commercial buildings to the drainage system that is used to treat and remove the waste. In the course of time, sewage pipes can become damaged or decayed, requiring repair or replacement as a result.
