Environmental

We install and build all the necessary infrastructure, from stormwater and clean water diversions, bunding and silt fencing to decanting earth bunds and sediment retention ponds, for environmentally safe earthmoving.

Keeping soil on the site and out of the water

Every earthworks job in the Waikato region has to keep its sediment on the site. Beacon Hill Contracting builds the controls that do it: diversion channels and bunds that keep clean water away from the works, silt fences and decanting earth bunds that slow dirty water down and hold the soil back, and sediment retention ponds that let the sediment settle before the water leaves the site.

These controls go in before the main works start and are maintained until the ground is stabilised, on our own bulk earthworks and commercial sites and wherever a plan calls for them.

What we build

Stormwater and clean water diversions

Channels and bunds that take clean runoff around the works instead of through them.

Bunding and silt fencing

Earth bunds and silt fences along the low side of the works to hold sediment back.

Decanting earth bunds

Bunds that pond dirty water and decant it slowly once the sediment has settled.

Sediment retention ponds

Ponds sized for the catchment, so the water that leaves the site has dropped its load.

Built to the regional guidelines

Waikato Regional Council's Erosion and sediment control guidelines for soil disturbing activities (TR 2009/02) set the minimum standards for these controls, and in many cases higher standards may be required. Almost every site needs an erosion and sediment control plan, and most consents require the controls to be certified as built to that plan or to the guidelines. Our controls are built to the guidelines and to the site's plan, which keeps the certification straightforward.
