HYGIENE MAINTENANCE OF STORED WATER DISTRIBUTION SERVICES
Water used in buildings is termed potable (fit for human consumption as drinking or cooking water) and non-potable a term used for all other water used within a building, such as washing.
Potable water is usually brought into the building and used straight from water utility’s mains supply, and as such is freshly supplied, having been subject to purification and treatment by the water utility.
Non-potable water is usually stored in tanks and distributed through pump, valves, softeners and pipework to other areas and rooms within the building.
These tanks are prone to contaminant build-ups which affect not only the efficiency of the system but may also have undesired health risks.
Water tanks are static items of plant which are not readily inspected, often located in restricted areas within plant rooms. Corrosion and sludge deposits can build up, harming the quality of the water and reducing the efficiency of the system.
Hygeia can address all of these issues with inspection and reporting on the condition of the tanks to formulate an action plan, with maintenance and restorative action achieved by draining down tanks, accessing and cleaning deposits, de-rusting and applying new linings and coatings to protect the tank from further corrosion. Pipework and outlets may be disinfected to eradicate any microbial activity, and the system certified and put back into operation.
