BERKSHIRE LA FLOOD REPORT FOR THE DIRECTOR OF PUBLIC HEALTH 1. Introduction The purpose of this paper is to summarise the flooding experience within Berkshire and to highlight the impact of the health of the local population. The winter of 2013 to 2014 was the wettest on record with over 7,800 homes and nearly 3,000 commercial properties flooded nationally. Within Berkshire the flooding started on 23rd December 13 and continued through until mid May 14. This was due to the different types of flooding events which took place. It started with fluvial flooding focusing mainly on the River Thames and lower River Kennet area. Following a short reprieve in early January 14 the fluvial flooding increased to include not only the Thames but the tributaries including the Rivers Pang & Sulham Brook, River Lambourn, the whole Kennet & Avon Canal stretch in Berkshire, the River Loddon and the River Colnbrook in East Berkshire In addition in early January groundwater flooding started to ‘breakout’ in the Upper Lambourn, Pang and Windsor areas. This ground water continued to rise with groundwater flood alerts being put in place. Large areas of West Berkshire in particular were affected which resulted in the groundwater rivers of the Pang, Lambourn and Kennet continuing to remain high and respond to any rainfall quickly. There are 2 groundwater alerts still in place and the River Lambourn is also on a Flood Alert (20 May 14). 2. Response. The response in Berkshire followed the lines of the TV LRF Flood Plan. During the early stages this involved teleconferences led by the Environment Agency, as the situation deteriorated in February these teleconferences were led by Thames Valley Police – often known as a ‘super Silver’, but in effect it is a teleconference with all the agencies Resilience staff. In early February West Berkshire, RBWM, Reading and Slough opened their Emergency Operations Centres. On 7 February a Major Incident was declared and scaled up the response to be a multi-agency coordinated response including the operation of a Tactical Coordinating Centre (TCG). RBWM had a TCG in place for wards affected by flood waters (predominantly flooding from the Thames). These TCG’s linked to the Strategic Coordinating Centre at Kidlington. The TCG’s had reps from Fire Service, TVP, Env Agency, Thames Water and the LA’s. Throughout this period all the Berks LA’s were communicating with each other via their control rooms but also in the areas affected by Airwave Radios if they had them. There was also mutual aid put in place with Bracknell supporting Slough and West Berkshire with resources and resilience staff. Reading BC supported West Berkshire on boundary related flooding areas and Wokingham supported by way of resources – sandbags and pumps. The RBWM depot at Tinkers Lane operated as the strategic hub 1 for sandbag distribution supported by military personnel to fill bags in readiness for use across the Borough and surrounding areas. RBWM supported vulnerable residents whose drainage and sewer systems were overwhelmed by flood water through the provision of chemical toilets for use in their homes thus mitigating any potential welfare or health impacts. The council also provided event style toilet in key locations within flood affected areas for wider use by residents and support staff involved with managing the incident. 3. Recovery Recovery started at various times for the different LA’s depending on the flooding type and the risk of future flooding. Even within LA’s the recovery has been in stages as the differing communities moved from response to a recovery status. Recovery for those flooded will be ongoing for some time. For the LA’s the main recovery element still outstanding relates to road and public rights of way repairs and management of the Government Grants. 4. General Impacts of Flooding. With the exception of Bracknell all LA’s had properties flooded as detailed below. However this is only one element of the impact. Many properties did not flood internally but were flooded below floorboards, surrounded by water and became ‘islands’ or had difficulties moving on the road network.

Health Impacts from Flooding During the flooding the main health issues being raised were: • Sewage flooding concerns – as the water inundated the system and they became overloaded there were issues of sewage backing up and flooding homes or spilling onto the road network. This raised issues of potential gastroenteritis outbreaks – none were reported by PHE. Clarity on guidance was the main area of concern • Drinking water – was it safe to drink. • Issues with a GP/Health worker insisting on a resident cut off by flooding being moved out rather than a visit by them – supported by the Las 4x4. After the floods: • Handling sandbags – what was the risk to people with respect to handling sandbags – were they contaminated or not etc etc. Clear messages as to how they should be handled were required. In areas where sewage covered the contaminated bags, they become contaminated and advice from the 2 Environmental Agency is that they should be disposed in landfill sites and that local authorities were to bear the costs. • Planning for longer term mental health concerns and psychosocial effects associated with the flooding appears to be unconsidered. 6. Involvement of Health During the flooding most Berks LAs linked in with their local lead for Public Health, Environmental Health Officers and Public Health England. Most messages were coming from PHE and this included any public messages. Role and actions of Public Health England The Public Health England advice was limited to providing health effects and risks. 1. Emphasis was on good hygiene principles. Flood water is assumed as potentially contaminated 2. Thames Valley Public Health England Centre supported the LA Public health with information leaflets/advice 3. Letters were sent to all GPs within the county 4. National surveillance- there was continuous collation and review of national surveillance data from NOIDS (Notification of infectious diseases), NHSD (NHS Direct) and RCGP sentinel. Review of local surveillance data on gastro intestinal symptoms in Berkshire remained at background levels all through. 5. It was emphasized that hygiene measures remain the hallmark of prevention. Health issues being linked to the floods in Berkshire 1. Eton Wick School Outbreak of Diarrhea and Vomiting There was a theory that the D&V outbreak in Eton wick school was linked to sewage effect from the flooding in the area. The Thames Valley Public Health England investigated the outbreak and could not link it with the flood. It was successfully managed as a routine outbreak. 2. Eton Wick Sewage Discharge Concern The Thames Water had permission to divert sewage to Roundmoor Ditch in Windsor and following the flooding, the residents started complaining of persistent odour and health symptoms which were attributed to the flood. A public meeting was convened to discuss the issue and TVPHE attended the meeting to support the local authority Public Health team and to plan long term measures. Unpleasant odour is a nuisance but does not result in significant health problem 3. Ham Island A similar event in Ham Island in Windsor was similarly investigated by the TVPHE and Thames water including measurement of air quality for hydrogen sulphide (from sewage decomposition) and obtained levels were well below threshold values. Measures were suggested to minimize the nuisance caused by the bad odour. 3 7. Lessons/concerns • Whilst documents were prepared in advance in relation to guidance on commonly asked questions on flooding relating to health…sewage, drinking water, sandbag handling, clean up etc., they need to be cross referenced with other guidance e.g. EA guidance on sandbags. • Consider the better coordination of public health measures using the core team to support PHE and links into the wider response element. • Ensure greater clarity on how all the different health elements are communicated with at a local level. This may require a Berkshire wide resilience forum for proper coordination of emergency response 8 Conclusion The Health and Wellbeing Board are asked to note this report and note the lack of immediate health issues.
