A little bit about me!• Originally worked on Japanese knotweed projects and was theMD of TCM.• Set up Ebsford Environmental with Mark Prout to offer bespokesolutions to both Invasive vegetation and Aquatic restorationissues• Have worked on a number of high profile projects and clientsincluding Hampton Court, The Royal Parks, Eden Project, 2012Olympics.• Specialise in sediment management, aquatic restoration, nativeflora and aquatic clearance.• Like Michael Bolton and long walks barefoot on the sand
• Why do we need a more sensitive approach?• What’s the alternative? Meet the Truxor• Effective management – The Ebsford approach• Case studies– Lake restoration – EA Sports Chertsey– Silt Pumping – Chesterfield/Cromford Canal– Aquatic clearance – Forestry commission• Other servicesIssues coveredtoday:
Why do we need a more sensitiveapproach?• More sites are being given higher ecological and environmentalclassifications meaning traditional techniques are becoming lesssuitable.• Larger machines cause a high level of disruption and have issueswith access• Ecological issues on site limit bank work and machinery size• Legislation over de-watering, dredged materials and wasteclassification means storage or disposal is complex and costly• Clients are looking for more sustainable solutions at all stages oftheir supply chain
What’s the alternative? – Meet the Truxor• Multi-purpose amphibious machine• Interchangeable attachments capable of:• Aquatic or semi-aquatic excavation• Silt pumping• Sediment removal using clamshell• Aquatic weed clearance• Heavy duty vegetation clearance• Extremely mobile and manoeuvrable, can access 1:2• Powered by bio-degradable oil and diesel• Lightweight, weighing less than 1400 kg• 4m x 2m x 2m, can access even the most difficult of sites• Ebsford current operate 3 machines across the UK• Utilised on over 90% of Ebsford’s aquatic projects
Effective Management – The Ebsford Approach• Initial consultation conducted to assess full scope of works• Preliminary site visit undertaken to provide scoping report• Feasibility study takes place on larger projects to include:• Depth tests and chemical analysis of sediment• Liaison with LA, EA or CL:AIRE in advance of formal submission• Analysis of cause and consequence• Specialist reports including Hydrology, ecology and agricultural• Full design of outline proposals• 10 point aquatic management strategy
Case Study – EA Sports Chertsey• Project was for restoration of a 10,000 sq m lake prior tocompletion of new European headquarters• Proximity to road and installation of high tech features meantsite was inaccessible to larger machinery• Urban area meant disposal or relocation of silt was impractical• Project included:• Installation of 800m of aquatic fencing• Removal and relocation of circa 7000m³ sediment• Creation of new marginal zones with specific native flora to give low levelimpact• Protection from high numbers of wildfowl• Installation of reed beds and phytoremediation to inflows and channels• Aerating fountains to improve overall health of lake• Clearance and protection of heavily overgrown and eroding islands
Case Study – Forestry Commission – Cross Lane• Project was for the management of a 30,000 sq m wetland arealocated in Wallasey• Poor management has seen rapid establishment of Phragmitesaustralis throughout the site.• Formal channels had become overgrown and terrestrial• Site was prone to regular flooding, causing damage tosurrounding residential areas and marsh areas to form inneighbouring amenity areas.• Previous attempts to find a solution had been unsuccessful withmachinery not able to work in semi-aquatic environment• Ebsford cleared 1000m channel and implemented a 5 yearmaintenance program
Case Study – Chesterfield/Cromford Canal• Project was for the dredging of in excess of 10,000m³ across almost 3km ofcanal in Derbyshire.• In addition to being a SSSI, the site is also home to one of the mostwidespread populations of watervoles in the UK.• The site was unable to be closed during the works meaning heavy interactionwith the public.• Encroachment within 1m of the bank was forbidden in certain areas so largermachinery was unfeasible.• Complex permitted meant that silt needed to be dewatered on neighbouringland using silt bags.• Receptor site identified was over 2km from the furthest area meaning siltrequired pumping in total 2.2km, thought to be the longest distance everpumped by amphibious machinery.• Proximity of both receptor sites to the canal network meant filtration ofwater and retaining of silt was crucial
