Ground Engineering has featured a Frog Environmental system to manage and treat silty water created by construction activities on phase one of the Environment Agency’s Rochdale and Littleborough flood alleviation scheme.

Working with Volker Stevin and the Environment Agency in conjunction with Rochdale Borough Council, the Littleborough flood defence works demonstrates how simple, site-specific solutions can have a big impact – using a “rain-ready” system of settlement ponds and silt capture channels to manage and treat silty water before it can be discharged into a watercourse.

The article highlights the project team’s innovative use of our Silt Capture Channels and Pipe Reactor as an effective water treatment system for cleaning surface water and reducing pollution risks.

We design environmentally-friendly, low carbon solutions to tackle common challenges on construction sites. By installing our Silt Capture Channel, the site team effectively managed surface water runoff without costly infrastructure or disruption.

We design and provide:

• Easy-to-use solutions
• Tailored site advice
• Real-world results
• Rain Ready™ systems which can be installed by site teams or through our network of installers.

Preparation is key: Silt pollution is a risk year-round

Good surface water management during construction is essential in preventing sediment pollution and minimising risk of prosecution, with the potential for large financial penalties and reputational damage.

Planning silt control interventions is relatively quick and painless. We offer a range of cost effective, low carbon solutions to help prevent risks on site:

• Silt Capture Channel – using a combination of our products, we’ve designed a silt capture device that treats between 900 -1800 litres per minute.
• Silt Mat™ – captures sediment and prevents resuspension
• Silt Wattle – reduces flow on sloping ground and in channels & ditches
• Floc Mat® – traps sediment and cleans muddy water using a non-hazardous flocculant
• Silt Net – for placement in lagoons to aid sediment deposition
• Treated Geo-Jute – for polishing water and lining channels
• Gel Flocculant – a low maintenance and non-toxic flocculant used to support silt and water separation to clean muddy water
• Pipe Reactor – mobile water treatment unit
• Bubble Curtains / Bubble Barriers – highly effective at aerating the entire water column and reducing movement of silt in water.

We also offer free training on the risks of silt on a construction site and you can download our Silt Control Toolbox Talk to communicate key points to your team.
