Water Risk Management in the Health Service Tom Martin BSc Environmental Innovations Ltd
Introduction - Water risk management does not just concern itself with Legionnaires disease - As a widely understood risk, this presentation seeks to highlight some of the more quietly talked about risks which can be just as costly and damaging - A healthcare facility should be treated with the same regard as a conventional industrial or commercial facility when considering the nature of water on site - Generally speaking, many healthcare facilities, especially campus style hospitals have old inherited sites with ongoing or difficult to deal with water management plans - Based on the above point, this puts healthcare FM at a disadvantage to private industry
Legionella - Regulation outlining Legionella ACOP L8 - Legionella is dormant below 20oC and wont survive above 45oC. - Water tanks should be at 60oC or higher, and distribution at the coolest part should be at 50oC or higher. - Human audits should take place monthly and recorded accurately. - Insulation is flagged up at numerous times. Bear in mind a five story building with a tank at the highest point, where would you start to find the point at which the water is cooling for example? - Many facilities are increasing their water temperature at great cost, however the outcome is generally that of scalding
Scalding - Although widely addressed in America, the UK does have HSE regulation on this - Care homes, pre-schools, wards where patients who have reduced mental capacity, are vulnerable to hot water and therefore scalding. - American study shows 5 out 6 surveyed facilities had water which could scald out their ‘faucets’. - Real-time Temperature monitoring can reduce costs in the form of waste - Hot surfaces - HSE suggest that surfaces should not exceed 43degree when a 'system' is at its maximum. This must mean that a radiator should be limited via the thermostat.

Leakage, and mismanagement of water - Leakage can lead to waste in terms of costs and down time - Leakage can cause outages in terms of repair times for major bursts - All of the above can cause ward closures, breaches in facility standards, and to the extreme, undiscovered leaks can cause building defects and structural problems. - Water costs, although relatively low in the UK, can add to a massive sum when considering the size of some health facilities. - Referring back to the scalding slide, changing the way health facilities use their radiators can go towards a cost cutting exercise
Blocked Sewers and Sewer Surcharging -Hospitals seem to be dogged with this issue more than most due to the nature of the media being disposed of - Wirelessly monitoring provides a real-time retro-fit solution which can plug straight into the building management system - As particularly sensitive areas can be affected, early warnings provide a proactive response rather than costly reactive responding
Major Spills and Oil Interceptors Incorrectly stored IBC’s on Hospital site, over surface water outlet Sensitive receptor which had a spill pollution a 5KM stretch, and killing all local fish species Remote and Automated Penstock valve for drain isolation Wireless interceptor alarm, retro-fitted for cost savings. Reduced services by 60%
