How often should a lift station be cleaned?
Confined-space cleaning of the wet well annually. Quarterly inspection of pumps and floats. Monthly checks of dosing equipment and float operation. High-grease stations may need quarterly cleaning.
Why it happens
Regular service prevents the accumulation of materials that cause pump failure and impede flow. It also removes the biofilm and sludge where odor-causing bacteria thrive. This source treatment is critical for controlling corrosive and toxic gases, like hydrogen sulfide, before they become a building-wide issue.
What to check
Observe pump operation for unusually frequent cycling, which can leave a persistent sludge layer. Visually inspect floats and walls for biofilm buildup. Check for accumulation of rags and wipes, as these are a primary cause of impeller clogs and pump failure. Note any persistent odors, as these often signal escaping sewer gas from dried seals or a need for source treatment within the well.
When to call a professional
Confined-space entry for wet well cleaning must be performed by qualified professionals. Any persistent sewer gas odor should be treated as an urgent issue, as the gases can be toxic and explosive. A professional can identify the source, whether from the station itself or elsewhere in the building's drainage system, and implement corrective measures safely.
How Luften handles it
Luften addresses lift station issues with a managed service program focused on source treatment. This involves the installation of continuous chemical dosing equipment, which can be done without taking the station offline. Our program includes documented service visits to verify system performance and inspect equipment. This service can be consolidated with other building needs like drain, grease, and trash system maintenance into a single contract with one point of contact.
