From Gross to Great – That’s Our Job!

When it comes to septic tanks, waiting until there’s a problem is never a good idea. Regular servicing keeps everything flowing smoothly, prevents costly damage, and avoids unpleasant surprises. Whether you need residential septic tank cleaning or have a blocked septic tank needing urgent attention, we’re the team for the job!

 We’ve been helping homeowners and property managers in Queenstown, Wanaka, Alexandra, and beyond with reliable septic tank cleaning and holding tank maintenance for over 25 years.

Why Septic Tank Maintenance Matters

Your septic system is one of the hardest-working (and least visible) parts of your property. Regular septic tank pumping and emptying prevents blockages, overflows, and ground contamination. For properties without town sewerage, holding tanks need scheduled cleaning to ensure capacity is never exceeded.

Our experienced team:

• Services tanks of all sizes across rural and residential properties.
• Operates a modern fleet (3,000–12,000L trucks) with extra-long hoses for hard-to-reach tanks.
• Provides digital reports for compliance or property sales.
• Offers 24/7 emergency response for urgent situations.

How Our Service Works

Booking with SJ Allen Holdings is simple. We’ll assess your tank, recommend a service interval (typically every 3–5 years for septic tanks), and arrive with the right truck for your site. For holding tanks, we set up automated schedules so you never have to remember to call.
