Naylor Environmental Smart Sponge® Technology used on Bellway Homes Oxlease Project in with Mackoy Groundworks and Civil Engineering Ltd

Bellway Homes wanted to build new houses on a plot of land at Oxlease Farm in Romsey which bordered a SSSI (Site of Special Scientific Interest) canal and needed stringent measures to meet the Environment Agencies requirements even before site works commenced.

Harry Long, Engineering Manager for Bellway Homes Wessex region sourced the Naylor Environmental Smart Sponge® Technology and instantly realised that a simple standard solution was available which would treat all the site runoff through both the Smart Sponge® and Enviroflow® Technologies.

During the initial set up stage we investigated several options however none complied and this led to onsite meetings with Naylor Environmental who offered us solutions with various aspects of products for the site. The Naylor Aquavoid® attenuation system and the Naylor Enviroflow Technology for filtering contaminated sediment were immediately sourced as perfect solutions engineered to enhance the Smart Sponge® Filter Chamber unit and agreed with Harry Long.

The Smart Filter Chamber units were positioned to capture all of the water runoff from the site passing through the Enviroflow® to filter out the majority of the fines and then through the Smart Filter Chamber which houses the Smart Sponge® Technology, this absorbs any hydrocarbons in the water and solidifies it into a safe manageable recyclable solid waste, whilst allowing stormwater to pass directly into the canal as a clean natural resource.

As a further pollution prevention measure Bellway Homes is installing Smart Sponge® Gully Adaptors into every road gully at the end of the contract to further protect the canal and drainage from pollution therefore committing to the Water Framework Directive and achieving three layers of treatment.

Naylor Environmental also provided their Aquavoid®-Traffic crate system for the attenuation storage requirement which enables a protected silt and inspection tunnel to be created through the structure to capture and retain the silt within the route allowing simple inspection and maintenance.

This is the first of many Bellway Homes projects that will have the Smart Sponge® and Enviroflow® Technologies installed at pre-construction phase to protect the local surrounding habitat therefore encouraging biodiversity before and during construction. This is a major consideration for Bellway Homes in their strategy of reducing the disruption to local species and wild meadows and is a first of its kind in consideration for fauna and flora.

When Bellway explained the problem we were not sure if the project would go ahead but the Smart Sponge® and Enviroflow® Technologies are such an easy treatment solution it was a no brainer for us to commit to the products and we will be using these technologies on all of our future projects that require this level of prevention.

The headache for the project was the SSSI and the fact that the whole site naturally falls towards the canal. When we spoke with Naylor Environmental the support and assistance in proving a solution was incredibly straight forward and the turnaround from design to installation was fantastically quick. This reduced any delays we were anticipating and we are ahead of schedule thanks to the plug and play style of Smart Filter Chamber which we can re-use on our next project. The Smart Sponge® Smart Gully Adaptors are a perfect solution for achieving the Water Framework Directive and Bellway Homes are now committed to installing these on all future projects where this is required by the local authority.
