Staying compliant during wet weather events on your construction site can be tricky, especially when the weather has its own ideas, often arriving unannounced! Dirty water runoff can wreak havoc, not only making it harder to work on-site, but potentially putting you in hot water if the dirty runoff breaks compliance rules. Before you break ground, you need to have a plan in place for how to deal with erosion and sediment control to protect your worksite AND the environment. Here are some tips for staying compliant on your rainy worksite.
1 Ground Cover!
Soil can’t get washed away if it is covered, so simply don’t remove vegetation from areas you don’t absolutely need to, and once areas ARE disturbed, plan to “cover” them back up as soon as you can. Options such as polymer spray, hydromulch, or even geofabric are all suitable solutions depending on the stage and size of works.
2 Diversion Bunds
Stop the otherwise clean water from coming onto your site and making things worse. Create a barrier protecting your site from overland flows and cut your problems in half! Soil diversion bunds are simple, cheap and easy ways to help keep your site protected.
3 Drainage Treatments
By creating site drainage systems with the appropriate design and surface treatments, erosion and sediment will be minimised. By using products such as gabion rock, flow check devices, jute lining, polymer spray, or any other number of treatments you can ensure the drainage lines stay clean and operational. This means your other controls such as sediment basins and sediment fencing remain cleaner for longer, meaning less work, less cost and less hassle!
4 Sediment Fencing
Sediment fencing is the most commonly used “solution” to protect worksites during a rain event. Unfortunately it is also has the title of being the most poorly used! If installed properly, along contours, trenched into the ground, properly maintained, and REMOVED at the end of works, then it’s a simple and cost effective way to catch sediment carried across your worksite by dirty water runoff – if not, then it’s a waste of your time and money!
Building basins for dirty water catchment is an inevitability (and a requirement) on some worksites. Since the water in these dams must be clean before it’s emptied, it’s important to make sure the design, construction and maintenance is carried out correctly. How do you clean the dirty water? Flocculation can makes this as easy as pie! Ecoscape Solutions can help design and apply flocculant into basins, causing fine particles of sediment to clump together and sink to the bottom, and Voila! Clean water can then be emptied from your basin before the next lot of rain.
