What Is A Wastewater Lift Station?
A wastewater lift station is a pumping station that moves wastewater from low areas of land to a higher point so it can again flow by gravity. Raw sewage makes its way underground in sloped pipelines that take advantage of gravity to keep costs down. The benefit of using a lift station in a sewage collection system is that it saves a substantial amount of money in excavation costs. Because sewer pipes live underground, digging trenches to either install them or repair them is costly. Installing a wastewater lift station at certain points in a gravity pipeline system saves money without sacrificing efficiency or functionality.
What regular maintenance is required for a wastewater lift station?
Lift stations require regular attention by the city’s sewer department to ensure all components are functioning appropriately. These include:
- Daily checks for obstructions or build-up of material that may clog the pumps
- Regular wet well cleaning
- Exercising of valves
- Hydro Jet (high-pressure water) cleaning, and a camera inspection of all collection system pipes on a 4 to 5-year cycle
What problems can arise from a poorly maintained wastewater lift station?
- When a lift station fails, by either a force main break, power outage, or pump failure, wastewater will collect in the lift station wet well and backup into the collection system. This could result in sewer backups into homes or cause wastewater to overflow from the lift station to the surrounding environment.
- Wastewater lift stations are also susceptible to clogs from fats, oils, and grease (FOG) generated by restaurants and businesses, as well as “flushable’ rags from households and multi-unit residential buildings.
- Wastewater lift stations can be a source of bad odors that become a nuisance to neighboring properties. The smelly gas from the collected sewage is also highly corrosive and can damage the wet well structure, the piping, and pumps over time.
