What is the primary function of a pump chamber in an OSSF?

The primary function of a pump chamber in an On-Site Sewage Facility (OSSF) is to collect and pump effluent to the drain field when gravity flow is inadequate. In many on-site sewage treatment systems, gravity is the preferred method for moving wastewater; however, in situations where the site’s topography does not allow for suitable gravity flow, a pump chamber becomes crucial. This chamber receives the effluent from the treatment tank and utilizes a pump to transport it to the drain field or leach field at the required elevation and pressure, ensuring that the system functions properly even in less-than-ideal conditions.

This role is vital to maintaining system efficiency and preventing backups or overflows, which could lead to environmental contamination and health hazards. Ensuring that effluent is appropriately moved to the drain field is essential for proper treatment and dispersal, demonstrating the crucial nature of the pump chamber in the overall wastewater management system.
