Overflowing septic tank
Slow drainage, sewage smells, wet ground around a tank or visible overflow can indicate that a septic system needs attention.
Helpful Guide
Gully Bowser Service Guide
Understand when a gully bowser is needed, what happens during service and how to prepare your property for safer, faster wastewater and septic work.
Know the Signs
When should you call a gully bowser?
A professional pumping service can help when wastewater, sludge or septic contents need to be removed safely from a property or site.
Blocked drainage
Persistent standing wastewater, repeated blockages or a drain that stops clearing may require professional drainage cleaning rather than repeated household fixes.
Wastewater accumulation
Homes, businesses and work sites can need pumping when wastewater or sludge has accumulated and must be removed from a tank, pit or collection point.
