SPECIALS & OTHER SIZES ON REQUEST

PRODUCT DESCRIPTION:
DRAIN WARDEN is a simple device designed to fit most surface grated catch basins.

The Drain Warden is an excellent defence for reducing and controlling the entrance of contaminants into our water systems.

Cars and trucks drip oil and grease on to the surface, which is carried into the catch basins by rain water. Eroded soil and wind blown debris, cigarette butts and ear plugs also usually end up in the drain system. Most of these catch basins ultimately drain into the sea, streams, lakes, or ground water aquifers. Held in place by the metal grate, the Drain Warden effectively removes coarse sediments, oil, grease, litter and debris from storm water. 
 
EASY TO INSTALL with Guide supplied. When sizing allow for 50-100mm of the Drain Warden fabric to overhang the edges of the surface grate so re-installation after maintenance is made easier

EASY MAINTENANCE The Drain Warden is easy to maintain & will generally consist of cleaning out debris and sediment, and replacing the oil absorbent pack. These units can save hours of sump maintenance time. The Drain Wardens fits into most catch basins and can be installed by the user.

Features
  • Economical filter unit - easy to install and maintain
  • Remove pollutants quickly "at the source"
  • Sizes to fit most surface drains 

PRODUCT APPLICATION:
Great for parking lots, vehicle storage/service areas, construction sites and industrial plants.

Oil & Debris Blocker

"Stop pollutants before they can reach the stormwater outflow"


 



PRODUCT CODES
UODB-1

PRODUCT DESCRIPTION:
OIL & DEBRIS BLOCKER assists with filtering out of pollutants that enter the drain system

Features
  • Stormwater is forced to flow through bottom of unit — floating trash and hydrocarbons remain on the water’s surface and out of the outflow
  • Installs quickly and easily in storm drain outflows
  • Low-profile allows vacuum trucks to clean catch basin without removing the unit
  • Dual component, all-polyethylene unit will not rust or corrode

PRODUCT APPLICATION:
Great for parking lots, vehicle storage/service areas, construction sites and industrial plants.

Permanent Catch Basin Insert

Removes concentrated contaminants from stormwater


 





PRODUCT CODES
UHFU-1

PRODUCT DESCRIPTION:
HYDROKLEEN PERMANENT CATCH BASIN INSERT removes Concentrated Contaminants From Stormwater at “Hot Spot” Drains

Removes hydrocarbons, organically bound metals, sediments and other organics from stormwater and industrial runoff.

Exceeds 80% sediment removal efficiency

Patented dual media filtration system provides consistent removal efficiencies.

Sealed, filtered system uses Sorb 44 and activated carbon to remove contaminants from water flow.

By-pass system prevents flooding or ponding during high flow storm events.

Excellent post construction control for “hot spot” applications. (Drains that are more susceptible to large concentrations of contaminants.)

Units available for round or square catch basin grates. Custom sizes available.

PRODUCT APPLICATION:
Wherever "hot spot" highly polluted drains require filtering

Drain Skimmer

Remove floating oils & fuels from the surface of water in a sump or drain


 



PRODUCT CODES
50cm x 50cm -  DSU-1
70cm x 70cm -  DSU-2

PRODUCT DESCRIPTION:
DRAIN SKIMMER - offers cost effective drain protection. A organic hydrophobic fibre absorbent pillow is placed into the skimmer pouch to absorb any hydrocarbons that float on the drain catchment basin surface water.

The Drain Skimmer will float in most drains or sumps where hydrocarbon contamination can occur. The sturdy screen pillow ensures long term exposure to the contaminated water and will resist coating or clogging which prevents further absorption. The hydrocarbon absorbing poly-propylene or biodegradable K-Sorb fibre inside the skimmer effectively absorbs oil over long periods.

The Drain Skimmer floats on the water surface and will not impede water flow.

Features
  • Quick and easy installation
  • Replaceable absorbent fibre pillow

PRODUCT APPLICATION:
Use in all sumps and drains where oils & fuels need to be removed
