A self-contained portable toilet stores its flush water and waste separately, allowing it to work without a mains sewer or water connection. The water and waste still need managing through the hire.
How does the flush work?
Our hire fleet uses fresh water flushing. The flush moves waste into a holding tank; it does not turn wastewater into fresh water. Other portable toilet designs may use different systems, so follow the instructions for the actual unit supplied.
The hand basin needs its own usable water and supplies. A working toilet flush does not prove there is enough water for hand washing throughout the booking.
Where does the waste go?
In a self-contained unit, it stays in the waste holding tank until serviced. It must not be emptied onto the ground or into a stormwater drain. Hired units are emptied through the arranged service or return process, rather than by the customer opening the tank.
Put only toilet waste and suitable toilet paper into the toilet. Wipes, sanitary items and rubbish can cause blockages and make servicing difficult.
How is a sewer-connect toilet different?
A sewer-connect unit uses a site water supply and drains to a suitable sewer connection arranged with your plumber. It avoids routine holding-tank pump-outs. Cleaning, restocking and responding to faults are still needed.
That option suits a site where connections can remain available. A self-contained unit may be more practical when services have not been installed or the work will interrupt them.
Does every hire include servicing?
No. Standard construction hire includes fortnightly pump-out, cleaning and restocking. More frequent visits are extra. Short-term event and trailer hire do not include ongoing servicing by default, so discuss heavier use or longer bookings in advance.
A fixed tank volume or flush count does not determine how long every booking can run. Users, water consumption and conditions affect the plan.
What do I need on site?
A firm, level position, safe user access and a clear route for delivery, collection and any service vehicle. Follow the handover instructions and contact us if a fitting fails or supplies need attention.
