Sanitary Mains

Underground sanitary sewer pipes. City sewer mains carry sewage flow from individual property connections to a general collection area, such as a treatment plant. Methane Lines are included in Sanitary Mains because they share geometry and attributes, however they should be queried out for analysis & always disabled from the network: Description: Gas lines connected to Port Mann Landfill to remove methane build up.
