PT600 Drainage Pits

TEPT600 Drainage PitThe PT600 by Fox Enviro are pre-manufactured drainage pits, combined with a silt basket. This is a complete unit ready to be concreted into the floor. It includes the grate and uni-seal (pipe seal) and has a treatable flow rate of 5L/sec.

With particle retention capabilities greater than 99% removal of particles >3mm in size the unit is highly effective whilst allowing water to freely flow through the pit. It’s rotationally molded from MDPE with a 100mm fitting ready for you to simply push a pipe straight onto.

Fully manufactured in Australia and delivered to your site or facility, this drainage pit is designed for areas that have debris, litter and or sediment. The PT600 replaces conventional stormwater drains saving considerable costs on of end line systems or other types of GPT’s in the network.

The PT600 can be used just about anywhere but considering it doesn’t have hydrocarbon retention capabilities we recommend it for areas with no vehicle access. They can be utilised across a site replacing drainage pits providing screening across the entire site.  Alternatively, they are good for wash bay floors.

Drainage Pit Maintenance

Silt baskets require cleaning and should become a regular part of housekeeping on site. If you don’t clean them out they can block up like any other trash basket. Make sure you maintain the drainage pit for optimum performance and always remember to use appropriate lifting gear for pit grates as they are too heavy for manual lifting.

BPT600 Drainage Pits

The baffled Pollutant Trap by Fox Enviro is a gross pollutant trap like no other. It’s a rotationally molded drainage pit combined with an inbuilt baffle and silt basket capable of retaining hydrocarbons from stormwater flow. This makes it well suited to car parks, hardstands and areas where the possibility of minor leaks and spill exist. The system is very efficient at retaining silt and sediment, trash and debris and protects the stormwater network 24/7.

Designed to be implemented during design, the baffled pollutant trap is a proven performer and replaces conventional stormwater drains saving extra costs on drainage pits and end of line systems.

Long-term servicing and management costs are much less.

BPT 600 Maintenance

The basket can be removed and cleaned and we supply absorbent pads for hydrocarbon clean up so you can completely service the trap yourself locking out the heavy-handed service contractors.


When considering the baffled pollutant trap remember they have a treatable flow rate of 5L/sec.

To ensure you correctly size the catchment traps you must work out the formula for runoff co-efficiency ensuring you don’t restrict or choke the stormwater network. Consult a hydraulic consultant or call us on 0434 314 803  for advice and information on the BPT600 Drainage Pit.
