Our Year in Numbers

Stonbury have just completed the financial year, for the period 1st July 2016 to 30th June 2017. Here’s a brief overview of our year in numbers: It has been a extremely busy, but enjoyable year for Stonbury and along the way, we have faced various success and challenges, that we hope will strengthen us as company going into the future. Over the last year we have achieved new goals and milestones, including our first new build reservoir, that wouldn’t be possible without the trust and collaborative approach to partnership that we embrace with our framework clients. Thank you to all our clients, staff and suppliers for a great year of opportunity and growth!

Slow Sand Filters Floor Replacement

In October 2016, Stonbury as framework contractors to the Northumbrian Water Group and Essex and Suffolk Water were asked for their involvement with an Investigation and Design (I&D) project, aimed at understanding the poor performing slow sand filters at the Layer Water Treatment works in the Essex supply area With the expertise in civil engineering and operational structures within the water supply network, Stonbury were selected to provide an added value solution for these challenges. For the initial investigation and design, Amec Foster Wheeler who work extensively with NWG (Northumbrian Water Group) were engaged to review particular issues around the slow sand filters, whilst also providing a full market appraisal. The scope of the project required an understanding of the issues with the slow sand filters, in order to develop a solution that would increase the overall output of the WTWs. With the information from the investigation reports, Stonbury, leading the constructability element of the project and developing budgetary and programme options, were able to provide NWG and E&SW with the best options for delivering the programme. The Solution After on-site investigatory work, it was apparent that the existing brick floors, common to many slow sand filters of this age, had silted up, causing the output of the filters to be limited. This ultimately led to the conclusion that the slow sand filter floors were in need of a replacement, with a like-for-like brick floor. The concerns with this solution included a high-risk repeat of performance issues. Instead, a solution was considered for the installation of an alternative ‘brick’ floor. This method would require the lifting of the original bricks, to be replaced with an accepted market flooring system for slow sand filters. Stonbury proposed the use of a ‘U’ block, which met the design parameters and most importantly, DWI approved for installation within the water supply system. With the decision confirmed on the preferred solution, and using the progress from the I&D stages, Stonbury officially tendered for the construction phases of the project, achieving an approved final costed solution for the initial 4No. filters of 2500m2 each. At the end of January 2017, we were delighted to be informed by the NWG board and Essex and Suffolk Water, the award had been approved to Stonbury. The Works The NWG operational site team at Layer WTWs were responsible for removing the media and once completed, works begun in earnest to remove the existing brick floors. The old brick ‘waste’ was subsequently re-used by a third party as infill material, substantially reducing landfill waste volumes. During the brick removal process, it was noticed that the central collection channel cover slabs, had received damage over the years and were also in need of replacement. Due to the necessity for the structural capacity of plant movement, we opted to design and construct the slabs on site in a specially made formwork arrangement, reducing both transport and procurement costs and manufacturing time. Each slow sand filter of 2500m2 required the laying of approximately 48,000 new ‘U’ blocks. With a singular block weighing 14kgs and at 140mm x 240mm x 215mm deep, Stonbury operatives laid just over 2500 tonne of blocks by hand. With the commitment of all our stakeholders involved in the programme and the greatly efficient methodology developed in the early stages of the scheme, Stonbury are pleased to report that all 4No. slow sand filters were successfully completed ahead of schedule, completing almost one month ahead of programme.
