4 easy ways to prevent rainfall runoff problems this winter
In Australia we love the rain, even when we don’t! For worksites it can be an inconvenience that costs you time and money, especially if it causes problems that need to be fixed further down the road. Water runoff is a major environmental concern, made worse in winter due to heavier rainfalls. When the rain runs off worksites, it collects sediment from the soil, as well as pollutants such as chemicals, oil, litter and pesticides. They are fed into the drains and waterways and often carried to rivers, lakes or the ocean, harming aquatic animals and polluting drinking water. It affects all sites, as runoff carries away the fertile topsoil needed for growing vegetation.
Developing a plan for dealing with dirty water runoff on your site is a priority, in order to reduce future problems. Ecoscape Solutions can help you out!
1. Book in Hydromulching
Hydromulching stops erosion at its roots. Treating the problem at its cause will give a much more effective long-term result, meaning less focus on sediment control down the track. To stop soil washing away in the first place, book in hydromulching as soon as you can. A quick visit by Ecoscape Solutions to lock down your site with hydromulch not only protects from erosion, but helps provide long-term vegetation cover, saving you time and money.
filters rainfall to the soil
provides added soil nutrients as the mulch breaks down
prevents erosion on slopes during plant establishment
improves germination of seeds and plants.
2. Apply polymer spray
When your site is not quite ready for hydromulch, but you still need to lock down your soil, spraying a protective polymer spray is the next best option. Ecoscape Solutions have a wide range of polymers available depending on your site requirements. With specialist equipment and experienced staff, we can apply polymer spray quickly for a fast, temporary solution until your site is ready for hydromulching.
is water repellant, providing a temporary solution to water runoff in areas prone to erosion and weathering
forms a layer of soil protection quickly on most terrains
3. Install sediment fencing
The humble sediment fence, comprised of stakes and synthetic filter fabric, shouldn’t be underestimated. It is used to block sediment that’s disturbed during construction, and reduces runoff velocity on a slope.
is easy to install with minimal disturbances to your site
reduces the speed of water runoff
filters out sediments to reduce downstream damage
is more effective at trapping sediment than hay bales and easier to remove at the end of your job.
4. Lay coir logs or filter socks
Coir logs are a compressed coir fibre made from coconut fibre husks. They have a lifespan of two to three years and are used for erosion control, managing water flow, capturing sediments, and stabilising banks and shorelines. Coir logs are environmentally friendly and 100% biodegradable – as coir logs break down, they act as a mulch for the soil and provide a micro-climate for plant establishment and regeneration. Ecoscape Solutions provides logs in different sizes so you can save money by buying only what you need.
If your site is large and you’ll need hundreds of coir logs, then filter socks are the answer! We can install directly on site using our blower truck, in continuous runs of hundreds of metres if needed. It can be a very cost effective solution to coir logs for large-scale sites.
Coir logs and filter socks:
are flexible and can be curved and shaped to fit the area needed
can be used in open drains to slow water velocity and catch sediment.
