BOX & V-GRATE DRAIN

Also commonly referred to as a drainage pit or storm water pit, these drains are used to contain stormwater runoff. Their design must be large enough to contain the water flowing into it, and for long enough so that it can pass through drainage pipes without overflowing. Below are some common box and v-grate drain protection methods.

Geofabric Drain Pollution Guard

Drain pollution guards fit under drain grates and feature a hollowed section to capture and rubbish, debris and coarse sediments in contaminated stormwater. Heavy duty geofabric filter material provides excellent water flow for effective drainage. Each drain pollution guard includes a bilge boom to remove hydrocarbons, oils and fuels. Available in different sizes and can be trimmed to suit most drains.

PROS: Simple and effective, excellent value

CONS: Requires maintenance to ensure ongoing effectiveness.

GuardDog Drain Filter

Drain filters are an innovative solution to control sediment and protect waterways. When placed over drains, these filters trap sediment and hydrocarbons in contaminated stormwater, allowing clean water to flow through into waterways.

PROS: Filters contaminated stormwater, traps silt and sediment, absorbs hydrocarbons, low profile, lightweight, durable, reusable, can be secured in place.

CONS: Drain grates can be difficult to remove for installation. Requires cleaning for ongoing effectiveness (compatible with street sweepers to reduce maintenance requirements)

DrainSAFE

This solution sits inside the drain pit and is made up of a barrel and a diffuser. As stormwater flows through the DrainSAFE, debris collects in the diffuser. Integrated filter absorbs hydrocarbons. The DrainSAFE features a built-in isolation valve that can stop flow into the stormwater system if required.

PROS: Can be emptied and cleaned periodically or as required. Being able to open or close the unit provides flexibility during risky activities or spill emergencies.

CONS: Considerable purchase and installation costs. Requires ongoing maintenance.
