Water Regulations Contract with Mace, Park House, Oxford Street, London

Mace logoMace were finding the completion of the water system at Park House difficult as the Contractors were unable to locate a commercial water softening device that met the requirements of the current Water Supply (Water Fittings) Regulations.

The background is that the building, comprising Commercial and Residential units, was specified to incorporate WRAS approved Water Softeners in accordance with Thames Water requirements. At the time of construction, no WRAS approved item was on the market resulting in the installation of non-compliant units.

park house water softenersRAH Consultancy were engaged to review the design of the installed units and advise a way forward. RAH based their review upon the requirement for a Water Regulations Compliant Water Softening device. Our work included;

  • Sourcing of such a device (none currently available)
  • Liaising with the manufacturer/installer
  • Production of layout drawings
  • Co-ordination of the Technical Submittals
  • Liaison with Thames Water Regulators
  • The organisation of factory testing of the proposed units
  • Undertake site inspections of the system at regular intervals up to the acceptance and signing off of the installations by Thames Water Regulators
  • General advice in dealing with Thames Water Utilities Water Regulations Department.

The units are now successfully installed and, following an inspection by Thames Water Regulators, a letter granting consent and a Certificate of Compliance have been issued.

Water Consultancy Contract with a Major UK Manufacturer of Medical Products.

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 acomplished 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.

 

kiwa logo Water Consultancy for Dutch National Water Test Facility KIWA

KIWA approached RAH Consultancy because they were aware that Richard Hurst had instituted the first test scheme for anti-scald thermostatic valves in Europe.

Water Regulations with Regard to Shipyard Hose Union Bibtaps

We were approached by a solicitor acting on behalf of a well known yacht brokerage and yacht builder to prepare a report with regard to the relevant sections of the Water Supply Regulations pertaining to the risk category of water supplied through hose union bib taps.

The issue referred to hose union bib taps positioned at various locations throughout the shipyard and used for;

  • general purposes
  • the provision of wholesome water to yachts
  • supply of water to the dry storage area
  • the wash down of yachts

It was considered by the local Water Undertaking that the risk classification for these devices should be that of Fluid Category Five, whereas it was considered by the Shipyard that the correct interpretation of the risk classification should be that of the lower Fluid Category Three for which a lesser category of back-flow protection would have been satisfactory. The classification of risk level would have significant cost and usage implications for the shipyard's operation.

It is worth noting that the interpretation was likely to set a precedent which could affect all shipyards in the UK.

We were requested to review documents supplied by both parties and to visit the shipyard to inspect the current water supply arrangements. The RAH Consultancy report indicated that in our opinion the highest Fluid Risk level was Fluid Category Four, although other aspects were of a lower category risk. A further report regarding the nature of the risk was supplied and all of the issues involved were submitted to the technical committee of the Water Undertakings. After careful consideration our proposals were accepted and a new interpretation of the Water Regulations was published defining the risk from bibtaps in shipyard applications.

 

Water Regulations Inspection of an American Airforce Base

Ensign of the Royal Air ForceRAH Consultancy was requested by one of our industry colleagues to collaborate on a Water Regulations inspection of a large American Airforce base. It is US government policy to ensure that the water systems on their overseas bases are designed and maintained to at least the standards required in the USA.

RAH first examined the differences between the US Code of Practice for the design and installation of hot and cold wholesome water systems and the UK Water Supply (Water Fittings) Regulations. Based on this study we recommended that the highest level of regulation from both the US and the UK would be used during the inspection.

RAH then advised and oversaw the Inspectors whilst they carried out a building by building inspection of the whole base. The inspection commenced with the most important and potentially highest risk buildings such as food preparation areas, and medical and sports facilities. At the end of this period both parties were satisfied that the works were being undertaken to the highest standards and the inspection of the rest of the base continued.

 

Water Regulations Inspection for a Major Supermarket Chain

RAH Consultancy was retained by the service company awarded the refurbishment contract of a large supermarket. We undertook a survey of the entire store's water system both front and back of house. Because the store was operating normally during the refurbishment the inspections were carried out overnight. Our inspection was comprehensive and included the identification of all redundant "dead leg" Our report included diagramatics of all Water Regulation non-compliances and a schedule of remedial action required.

 

Writing Water Regulations City & Guilds Course for HSL Compliance

The work included the provision of all course notes and examination papers for the in-house City and Guilds course. On completion of the design stage we acted as the course lecturer for the organisation, this included conducting the practical element of the installation and maintenance module as well as the theoretical modules.

On completion of the syllabus the company found that their employees had increased confidence and greater competence in the undertaking of their duties.
