Summer in New Zealand is all about long days, BBQs, and visitors – but if there’s a mysterious pong drifting across your section, it’s not the sausages burning. Chances are, your septic tank is trying to tell you something.
Hot weather and extra guests are a recipe for septic overload. When a tank is already near capacity, a few more showers, extra laundry, and extra flushes can push it over the edge. The result? Bad smells, slow drains, gurgling pipes, or even wastewater backing up into your home or yard.
Here’s what could be happening:
- Built-up sludge: Solids naturally settle in your septic tank over time, taking up space. If the tank isn’t emptied regularly, there’s less room for new wastewater. In a tank with a soakage field, excess solids can escape into the outlet and clog pipes or the soakage system. In a holding tank, the wastewater simply fills up, and once it’s full, it can back up or overflow – and that’s when the smells appear.
- Blocked filters or outlets: Heat and heavy use can stir things up inside the tank, creating blockages that slow down how wastewater leaves the tank (if it has a soakage field).
- Overloaded soakage fields: For tanks connected to soakage systems, saturated or compacted ground can prevent effluent from draining away, causing surface pooling or odours.
The fix? HydroVac can empty your tank, clear blockages, and inspect your system – whether it’s a traditional septic or a holding tank – to make sure it’s summer-ready. Regular emptying (every three to five years for most homes, depending on size and use) keeps your system working properly and odour-free.
