Hotels can have long periods, during low season, when their water system is unused and can attract bacteria. Also they tend to keep the water at a luke-warm temperature, so as not to scald residents, but this means bacteria will thrive.
Spa hotels and leisure clubs with swimming pools, hot tubs and cooling towers can be very susceptible to bacteria in stagnant, warm water.
Holiday Parks with swimming pools, spas, clubhouses, restaurants and shower blocks all need to ensure their water is safe to protect their residents, staff and reputation. Risk assessments can be carried out at any time, with any identified remedial works being carried out in low season.
