Grinding Process Benefits:
- A small diameter, reducing the torque required on start-up and eliminating jamming with normal use.
- Operates with a staggered scissor action to slice through difficult objects such as pantyhose, which may be flushed into the sewer system.
- The entire Pressure Sewer chamber is pumped free of all solids and liquids on start-up
- Your system remains clean and odourless.
Since the introduction of Pressure Sewer technology to the Australian market, Aquatec has played a pivotal role in replacing septic tanks with sealed Pressure Sewer Systems.
Reduced Excavation Periods
Aquatec’s pre-engineered Pressure Sewer Systems are delivered on-site as a complete unit for immediate installation, reducing the period of excavation required and minimising disruption to surrounding flora and fauna.
Our systems can be delivered to site, installed, connected and commissioned within an 8 hour time period, heavily reducing C02 emissions associated with prolonged periods of excavation and installation.
Aquatec’s pumps incorporate an anti-syphon valve to offload a small, steady stream of effluent back into the chamber to aerate effluent in the tank for ongoing odour reduction.
Moulded Inlet Stubs
Aquatec’s Pressure Sewer chambers are engineered with Moulded Inlet Stubs to provide a guaranteed seal between the chamber and inlet pipes. Flexible coupling joins connect pipes from plumbing connections to the chamber, eliminating the need for on-site drilling into chambers and rubber seals prone to environmental leaks and spills.
Aquatec’s Pressure Sewer Systems incorporate premium grade pipework & components to safeguard against system failure & corrosion for the long-term.
16 Bar Rated Pipework
Aquatec’s 16 bar rated flexible pipework handles up to 160 metres of pressure, providing added safety protection against burst pipes and leaks during scheduled maintenance or system failures.
316 Grade Stainless Steel Components
Aquatec’s Pressure Sewer Systems incorporate premium 316 stainless steel components; internal valves, pump stand, tank outlets and quick release camlock connectors are protected for the long-term.
Individually Fused Circuits
For added safety protection, every Aquatec Control Panel incorporates individually fused circuits to detect discrepancies and shut down power.
Quick Disconnect Plug
Aquatec’s IP68 Quick Disconnect Plug eliminates the need for a qualified electrician, risk of electric shock and features a quick pump change over for your convenience.
Ground Level Access
Aquatec’s Pressure Sewer chambers are designed to provide ground level access for the service and maintenance of pumps, valves and level controls, eliminating the need for confined space permits and associated WHS risks to maintenance personnel.
Closed Valve Protection (CVP) Switch
Aquatec’s CVP Switch delivers complete asset protection across reticulation pipework, eliminating excessive pressure build-up and system management during maintenance or power failure. The CVP Switch measures pressure in the reticulation and switches off the pump if pressure exceeds 60 metres head. As pressure decreases, the pump will automatically restart, providing full protection to pumps and reticulation for the life of the asset.
Available in fibreglass, 316 stainless steel or aluminium and rated to AS/NZS 3996, Aquatec’s Safety Grates provide an added lay flat, safety fall arrest system for maintenance personnel.
