This manufacturer maintained a large research establishment consisting of a range of buildings of various complexities at a multi acre site. They had been subjected to a Water Regulators inspection at another of their sites and this had resulted in the need to replace systems so as to remedy the non-compliances discovered. These systems alterations were insisted upon by the local water undertaking and it was necessary to complete them to the Water Undertaking imposed timetable. Disruption to operations and the costs involved were considerable.RAH Consultancy was contracted to examine three buildings at the research establishment and provide a report on the water systems within these buildings and to suggest any remedial action to be undertaken.RAH provided this report and a meeting was then conducted with the local Water Undertaking’s Inspector. The manufacturer then provided a schedule of their proposed remedial actions and this was agreed by the Water Undertaking. As the works were conducted on a voluntary basis it was possible for the manufacturer to plan their remedial actions and agree a time-scale for these changes which could be accomplished and costed within their pre-planned maintenance schedules. The manufacturer eliminated all surprises and unplanned costs to their operations and gave an example of co-operation to their local Water Undertaking which was appreciated.
