What are some examples of difficult to pump substances that can appear in pump stations?


Animal hair and grease from fryers are two examples of difficult to pump substances. Romtec Utilities has designed lift stations that needed to address these substances. Animal and pet hair is difficult because it as a tendency to clog pumps. Hair from animals does not break down easily, and it tends to wrap around moving parts. Pumps in systems with known levels of animal or pet hair should be serviced several times throughout the year. Grease will usually build up on the surface of wastewater and interfere with the level sensing devices. Grease can also build up on the walls of the sump, in the pumps, and in the system piping and valves. The best approach is to eliminate grease from the system by installing grease traps at the point of origin.
