Storm Water
SINGLE PIT DIVERSION SYSTEM
MAK Water’s Clearmake™ Single Pit Diversion Systems allow wash-down, first-flush, and other contaminant fluids to be captured from un-roofed hard-stand areas for disposal, or pre-treatment prior to sewer discharge. Typically a diversion system would work in conjunction with a wastewater treatment system such as an Oil Water Separator (OWS), Gravity Clarifier (GC) or Dissolved Air Flotation (DAF) system. During a rain event, diversion systems allow clean rainwater to be harvested or discharged to the storm water system.
DUAL PIT DIVERSION SYSTEM
MAK Water’s Clearmake™ Dual Pit Diversion Systems allow wash down, first-flush, and other contaminant fluids to be captured from un-roofed hard-stand areas for disposal, or pre-treatment (prior to discharge to sewer). During a rain event, diversion systems allow clean rainwater to be harvested or discharged to the storm water system. Systems are compliant with DEHP, DAFF & OH&S regulations.
GROSS POLLUTANT TRAP (GPT)
MAK Water’s Clearmake™ Gross Pollutant Traps (GPT) treat rain and storm water runoff from hardstand or car park areas. The GPT protects the storm water system and the surrounding environment from contaminants such as silt, hydrocarbons, and other debris that can accumulate and be washed off of hardstand and car park areas. MAK Water Clearmake™ GPTs are a cost effective alternative to larger concrete GPTs, which are more expensive to purchase and more time consuming to install. MAK Water Clearmake™ GPTs are compliant with local Council and Department of Environment and Heritage Protection (DEHP) requirements.
STORM WATER MANAGEMENT SILT TRAP
MAK Water’s Clearmake™ Silt Trap treats rain and storm water runoff from open hardstand or car park areas and indoor wash bays. The Silt Trap protects the storm water system and the surrounding environment from contaminants such as silt and other debris that can accumulate and be washed off the hardstand and car park areas. The Silt Trap unit comes complete with an easily removable silt tray, which is quick and simple to maintain.
HYDROCARBON SPILL CONTROL
MAK Water’s Clearmake™ Hydrocarbon Spill Control systems are an integral part of safe water treatment and containment in fuel station forecourts and other hazardous areas with potential for gross hydrocarbon spills. This specialised pre-treatment package is largely used in any hardstand area, wash bay, or fuel station sites where pre-treatment of wastewater containing hydrocarbon, silts, and solids is required and the addition of gross spill containment is necessary.
Storm Water Management Silt Trap
MAK Water offers a range of storm water drainage solutions for our clients. The Clearmake™ Silt Trap treats rain and storm water runoff from open hardstand or car park areas and indoor wash bays. This Silt Trap protects the storm water system and the surrounding environment from contaminants such as silt and other debris that can accumulate and be washed off the hardstand and car park areas. It comes complete with an easily removable silt tray, which is quick and simple to maintain.

Gross Pollutant Trap
MAK Water’s Gross Pollutant Trap (GPT) treats rain and storm water runoff from hardstand or car park areas. The GPT protects the storm water system and the surrounding environment from contaminants such as silt, hydrocarbons, and other debris that can accumulate and be washed off of hardstand and car park areas.
MAK Water GPTs are a cost effective alternative to larger concrete GPTs, which are more expensive to purchase and more time consuming to install.
GROSS POLLUTANT TRAP SPECIFICATIONS
Moulded from a selected grade of polyethylene, MAK Water Gross Pollutant Traps are light and easy to install. The external ribbed design provides support and strength to resist external forces from backfilling while reducing the risk of floatation.
Overall Dimensions (mm): 1,400 x 838 x 1,200
The Gross Pollutant Trap unit utilises a triple action filtering process incorporating a positive baffled separation sump fitted with a tray to remove silt and sediment.
The outlet pipe blister is 400mm wide with a multi-size boss and socket arrangement permitting pipes of varying sizes to be connected using rubber sleeves and stainless steel worm drive clips. This allows pipe cover of 300mm for 300NB and 225NB pipes and 330mm cover to the 150NB connection.
MAK Water GPT Risers can be used if the depth to the pipe needs to be greater. This simply drops into the rim of the pit and locks over the lip.

Dual Pit Diversion System
MAK Water’s Clearmake™ diversion systems allow wash down, first-flush, and other contaminant fluids to be captured from un-roofed hard-stand areas for disposal, or pre-treatment (prior to discharge to sewer). During a rain event, diversion systems allow clean rainwater to be harvested or discharged to the storm water system. Systems are compliant with DEHP, DAFF & OH&S regulations.
Where required, control systems are PLC driven, customisable, and can be designed to meet intrinsically safe circuit requirements for hazardous areas.
APPLICATIONS:
- Vehicle wash down bays
- Un-roofed hardstand areas
- External storage areas
- External bunded storage areas
- Fuel or chemical storage areas
- Service stations
- Storm water and rainwater harvesting applications
- Mining and heavy equipment workshops
- Airplane wash down bays
- Airport taxi/runway
PROCESS DESCRIPTION:
DEMAND DRIVEN
MAK Water’s Demand Driven diversion systems are a simple system using only a hydraulic demand valve without a controller. Located in the washer feed line, the demand valve uses hydraulic pressure to open the diversion valve when the washer feed line is opened and a wash down is occurring. When the wash down activity has stopped, the diversion valve will close allowing rainwater falling on the designated area to divert to the storm water system.
FIRST FLUSH
MAK Water’s First Flush diversion systems use a PLC controller in conjunction with a first flush manifold located in the washer feed line to open/close the diversion valve. Further to this basic function, this system is designed to take a 10mm first flush from the wash pad area at the beginning of a rain event. The first flush is captured in a holding tank for treatment prior to release to the sewer system. Once the first flush has been taken, the diversion valve will close allowing all subsequent rainwater falling on the designated area to divert to the storm water system.
WASH-DOWN SHUTDOWN
MAK Water’s Wash-Down Shutdown diversion systems incorporate the same features of the first flush system with the addition of a shutdown feature in a rain event. A rain sensor is used to signal a rain event to the controller, which then shuts off supply to the washer for the duration of the rain event. This feature stops any cross contamination between the sewer and storm water connections and is a requirement in some localities.
Hydrocarbon Spill Control
MAK Water’s Clearmake™ Spill Control systems are an integral part of safe water treatment and containment in fuel station forecourts and other hazardous areas with potential for gross hydrocarbon spills. This specialised pre-treatment package is largely used in any hardstand area, wash bay, or fuel station sites where pre-treatment of wastewater containing hydrocarbon, silts, and solids is required and the addition of gross spill containment is necessary.
MAK Water’s Clearmake™ Spill Control systems are supplied standard with a conductive spill detection and pump run probe, a flame proof 3-phase low shear diaphragm pump, a 3-phase control panel with intrinsically safe circuitry allowing installation of electrical components in a hazardous area, and a Clearmake™ oil water separator for pre-treatment of waste water prior to discharge to sewer
