Leach Drains

If your property isn’t connected to the mains sewer system, a properly designed and installed leach drain system is essential for safely dispersing wastewater. Mackie Plumbing and Gas provides expert leach drain installations, replacements, and upgrades across Perth and regional WA — ensuring your system is effective, compliant, and built to last.

Leach drains (also known as soakage trenches) work in conjunction with septic tanks to allow treated wastewater to safely filter into the surrounding soil. A poorly installed or failing leach drain can lead to unpleasant odours, pooling water, and environmental contamination — so getting it right matters.
