Can you install multiple small septic systems for a larger property?

Design Considerations for Multiple Small Septic Systems

When designing a multiple small septic system setup, it’s essential to consider the size of the property, the number of users, and the local regulations. A general rule of thumb is to divide the property into smaller zones, each with its own septic system, with a minimum of 1/4 acre per septic system. This approach can help to ensure that each system is not overwhelmed and can function properly.

Technical Requirements for Multiple Small Septic Systems

Each small septic system should be designed to meet the specific needs of the zone it serves. This includes conducting a perc test to determine the soil’s ability to absorb wastewater, selecting the appropriate drainfield size, and ensuring that the system is properly sized to handle the wastewater generated by the users. For example, a small septic system for a 1-bedroom home might be sized at 300-400 gallons per day, while a larger system for a 5-bedroom home might be sized at 1,500-2,000 gallons per day. It’s also essential to consider the type of septic system used, such as a conventional gravity system or an alternative system like a mound system or a drip irrigation system.

Maintenance and Upkeep for Multiple Small Septic Systems

Maintaining multiple small septic systems requires a regular maintenance schedule to ensure that each system is functioning properly. This includes pumping the septic tank every 3-5 years, inspecting the drainfield for signs of failure, and addressing any issues promptly. It’s also essential to keep accurate records of maintenance and repair activities for each system, as this can help to identify potential problems before they become major issues. By following a regular maintenance schedule and staying on top of system performance, property owners can ensure that their multiple small septic systems continue to function properly and efficiently.
