Legionella Risk Assessment and Water Hygiene Services
throughout the UK

We provide expert consultancy and support for the health and safety, hygiene and maintenance of water systems across the UK

  • Legionella Risk Assessment

    The L8 states that a ‘suitable and sufficient assessment must be carried out to identify and assess the risk of exposure to Legionella bacteria from work acitivites and water systems on the premises and any precautionary measures needed. The dutyholder is responsible for ensuring the risk assessment is carried out.’

  • Water Analysis

    Water analysis is an essential part of any water hygiene regime to ensure the control of Legionella and bacteria in water systems. DCS uses a UKAS accredited laboratory to offer a comprehensive chemical and microbiological analytical service.

  • Water Tank Refurbishment

    DCS are able to undertake the cleaning and refurbishment of a wide variety of water systems and associated pipe work with a minimum disruption to your business.

  • Disinfection by Chemical Injection

    Under certain conditions, water systems may require disinfection prior to being put into service. Through our comprehensive knowledge and effective equipment we can ensure the disinfection is carried out to a high standard.

  • RPZ Valve Testing

    RPZ valves must be tested on an annual basis, and in some cases every six months in order to meet local water authority requirements.

  • Water Hygiene Training

    We can provide water hygiene training to suit your requirements. Please contact our office for a  consultation.

  • Schematic Drawings

    As an integral part of the Risk Assessment, the Schematic Drawing takes into account the individual nature of each site and considers the system as a whole and not specific sections. Using the most up to date version of CAD, we produce a high quality drawing at a competitive price.

  • Water Hygiene Monitoring

    The risk from Legionella in water systems is greatly reduced if regular monitoring is carried out as part of the legionella risk management programme.

  • Clean and Disinfection Services

    DCS can help to design and carry put a full clean and disinfection program for onsite water systems, associated with the control of Legionella and other water born bacteria.

  • Dead Leg/Dead End Removal

    Dead Legs are sections of pipework leading to a fitting through which water only passes infrequently. Dead ends are pipes which have been capped/cut andf are causing standing water. They can be generated through the changing or modifying of a water system. DCS can ensure the effective removal of any Dead Leg or Dead End.

  • Thermostatic Mixing Valves

    TMV’s are valves that use a temperature sensitive element to blend hot and cold water to produce water that safeguards against scalding. DCS has qualified staff to commission and service TMV’s.

  • Water Softeners

    We can supply, fit, commission and service all makes and models of water softeners.
