BLOCK 39 – VAUGHAN ON

Stormtec was contracted to the GTA to assist with the

dredging of a stormwater retention pond in a

residential area of Vaughan. Stormtec shipped

flocculent and flocculent injection equipment to the

project, which required 100m3 of sediment to be

dredged out of the pond using a remote control

dredging system.

The customer had tried various other flocculents with

little success and hoped that Stormtec would be able to

help provide a solution. A Stormtec field technician

installed 2 flocculent injection systems on site, one to

inject the LBP 2101 pre-treatment biopolymer and the

second to inject the chitosan flocculent in order to

reduce the 40% solids that were present in the water

stream.

The quality of water entering the dewatering bag had

such high turbidity that it didn’t even register on the

NTU scale, however, the combination of the HaloKlear

DPS flocculent system and Stormtec’s on site ability, the

water discharged from the bag was below 20NTU.

This type of dredging is poised to become the

standardized method for sediment removal from water

bodies. This project has proved once more, that

Stormtec is at the forefront in providing innovative

water management solutions.
