Water Compliance Services
What you should know
Following the water risk assessment there will need to be a management plan put in place. The complexity of the water system within the building will dictate what the requirements of this plan will be, but it could involve:
alterations to pipe work
sampling and testing
With nationwide coverage and fully trained technicians, Landmark Specialist Solutions can assist you with the ongoing management of your water systems to ensure compliance.
Following the completion of the water risk assessment, there may be a requirement for specific one-off actions and will be a requirement for ongoing monitoring to ensure compliance. All these activities will have to be recorded and records kept.
In older buildings, it is not uncommon to find modifications have been made to the water system. Items may have been relocated or removed completely but the pipe work left with "dead ends", which are runs of pipe that go nowhere but still have water present. If this is the case then these dead ends contain stagnant water which increases the danger of the Legionella bacteria and the pipework will need to be modified to remove the dead legs.
Where there are long runs of pipe work or where hot and cold pipes run adjacent to each other, if they are not already, it will be recommended that the pipe work is insulated.
Water Temperature Testing
There are a number of water temperature testing requirements that may be specified:
the outlet temperature at the calorifier - should be above 60°C
the outlet tap temperature - should be below 20°C for 2 minute of running cold taps
- should be above 50°C within 1 minute for hot taps
the inlet TMV temperature - should be above 50°C
Cleaning and Chlorination
Tanks used for storing should always be sized such that the water is replaced on a daily basis as a minimum. Tanks also become become dirty over time and in some cases sludge will collect on the bottom of the tank. Tanks should be cleaned and disinfected on a regular basis and it is common for the whole system to be chlorinated to kill any bacteria present.
Scale is a nutrient will allows bacteria to thrive and can occur in many locations. Inside calorifiers, on tap and shower outlets etc. This scale should be removed at regular intervals particularly in the case of shower heads which are designed to produce water droplets and hence carry a higher risk of Legionella.
