What type of system must be installed before a pressure distribution system?

The requirement for a two-compartment septic system to be installed before a pressure distribution system is grounded in the need for effective treatment and management of wastewater. A two-compartment septic system is designed to improve the separation of solids and provide an additional level of treatment for effluent before it is distributed through a pressure system.

In a two-compartment setup, the first compartment allows for primary treatment, where solids settle out and anaerobic digestion occurs. The second compartment allows for further settling and digestion, which helps to clarify the effluent. This effectively reduces the levels of suspended solids and other contaminants, ensuring that the effluent entering the pressure distribution system is of a higher quality, which is essential for protecting the environment and the efficiency of the disposal method.

Additionally, the pressure distribution system relies on this pre-treated effluent and helps ensure equal distribution across the disposal area, which is critical for preventing clogs and ensuring that the surrounding soils can properly absorb and treat the effluent. Therefore, the use of a two-compartment septic system is a crucial step in establishing an effective pressure distribution system, providing both the necessary treatment and preparation of the wastewater.
