Yes, regular maintenance can help extend the time between septic tank emptying. Practices such as conserving water, avoiding the disposal of non-biodegradable items or harsh chemicals down the drain, and having regular inspections can all reduce the amount of solid waste and scum that accumulates in the tank. Additionally, using septic tank additives as recommended by professionals can help break down solids more effectively. However, even with diligent maintenance, septic tanks will still need to be emptied periodically to prevent overflows and system failures.
