What maintenance is required for alternative septic systems?

Regular Checks

Alternative septic systems are more complex than traditional septic systems and require more frequent maintenance. The drainfield should be inspected every 3-6 months for signs of clogging, such as slow draining or water pooling on the surface. During inspections, check the drainfield’s soil absorption rate by pouring water onto the surface and observing how quickly it is absorbed. This can be done using a perc test, which involves digging a hole 12 inches deep and observing how quickly water disappears.

Dosing Tank and Pump Maintenance

The dosing tank and pump are critical components of alternative septic systems. The tank should be checked every 6-12 months for sludge buildup and scum formation. The pump should be inspected every 3-6 months to ensure proper function and replace the check valve every 1-2 years. It’s recommended to replace the pump every 10-15 years, depending on usage and manufacturer recommendations.

Maintenance Tasks and Frequency

Perform the following maintenance tasks on an alternative septic system:

• Check the drainfield every 3-6 months
• Inspect the dosing tank and pump every 6-12 months
• Replace the check valve every 1-2 years
• Replace the pump every 10-15 years
• Perform a perc test every 6-12 months
• Keep detailed records of maintenance and inspections for future reference. Regular maintenance is key to extending the lifespan of an alternative septic system and preventing costly repairs.
