Foul Drainage Case Studies
Housing development, Derbyshire
Peak Associates have provided a number of services for the development of a former farm in Stretton, Derbyshire, the most recent being a feasibility report to assess the most suitable means of discharging the foul and surface water that will be generated by the site.
The work involved percolation tests at the site and conceptual designs for the location of a treatment plant and soakaway for the foul discharge. Peak also completed the Environmental Permit for the site and will liaise with the Environment Agency throughout the process to ensure this runs smoothly for our client.
The conceptual SuDS design involves the use of soakaways in the residential gardens and a larger soakaway and wetland to ensure that the design will provide storage for high intensity rainfall events.
Country Estate, Stockport
Peak Associates have worked with one of the UK’s leading heritage organisations at a number of their “mansion” properties throughout England and Wales for many years. Our most recent project was at Lyme Park in Disley, Stockport. A drainage investigation was undertaken to assess the state of the existing foul and surface water drainage on the estate. A review of a wealth of historic plans was also undertaken to help find old and often buried drainage features on the estate.
Additional investigations will now be targeted to ensure that the site will finally have a full and detailed drainage plan of the whole estate which will help with the planning of future developments.
Peak Associates also assisted with a monitoring survey of the estates effluent discharge over a 12 month period. The study has provided information which has helped the estate with future developments, and helped to assess the efficiency of the Victorian sewage treatment works. With some maintenance work by National Trust staff the works are operating well.
