Ilkley Clean River Group WQR0084

Written evidence from Clean River Group

Prof Becky Malby, RSA Fellow lives in Ilkley and works at London South Bank University as a Professor of Health Innovation. She is a co-founder of the Ilkley Clean River Group, which was set up out of the frustration of some Ilkley residents with the lack of response to continued reporting of sewage discharges into the at Ilkley. What we found sparked national interest and 2.5 years later we achieved the first river to be awarded Designated Bathing Status, a citizen science protocol for testing river water quality, and have been promised action to clean up the river. We have shown that sewage discharges are normal and regular practice; that despite the agencies’ assertions that everyone knows it’s happening; the public are actually outraged about it; and that these sewage discharges are a threat to people’s health and to the ecology of the river. The Ilkley campaign has attracted national media attention capturing the nation’s mood in terms of protecting our environment, securing best value for our communities and seeking accountability from agencies. From January 2020 – March 2021 our campaign has been covered by BBC news and Countryfile, Channel 4 News, The One Show, the World at One, Women’s Hour; has featured in The Guardian multiple times, in The Times, the Financial Times, as well as regional and local newspapers. Restoring the river in Ilkley and beyond We are seeking sewage facilities for Ilkley that only discharge raw sewage compliant with the European Urban Waste Water Treatment Directive, (extreme weather); which do not discharge sewage solids into the river or onto the riverbank; basic ongoing maintenance of the sewage infrastructure. The Campaign We have worked to: 1. Understand what’s really going on – (a) data – through our citizen science on microbiological water quality, (b) FOI and requests to secure storm overflow frequency, (c) collaboration with Water to investigate infiltration and pollution sources. 2. Hold the agencies to account for the real situation we are facing through Town Meetings and the media. 3. Secure Bathing Status as a means to catalyse regular water quality testing for feacal bacteria and a clean-up. Ilkley Clean River Group WQR0084

1. Context: The River at Ilkley On hot sunny days over 1000 people use the river at Ilkley for recreation. Figure 1: the river at Ilkley in the Designated Bathing Status Application showing the distinct stretches of usage.

2. Understanding What is Really Going on (a) The extent of storm overflow discharges at Ilkley The sewage works at Ilkley continues to discharge raw sewage into the river at Ilkley when it rains. YW reported 123 days of sewage discharges in 2018, 201 discharges over 114 days in 2019. For 2020 we are verifying the data from but it looks like 120 days with discharges, only 10 of which were in heavy rainfall (with thanks to Peter Hammond). Our data shows 8mm of rain can trigger a storm overflow discharge of raw sewage into the river. Ilkley Clean River Group WQR0084

According to the SOAF (Storm Overflow Assessment Framework) 40 ‘spills’ a year over 3 years or >60 spills a year should trigger the SOAF requirements for investigation and solution finding (a 15-year process). The EA did not know the extent of the ‘spills’ (raw sewage discharges) at Ilkley because their water monitoring was not triggering investigation of the spill frequency. Yorkshire Water knew about the frequency (they provided us with the data) but was not required to report it. All reported incidents were legal under the Consent Limit for the treatment plant at Ilkley set 18 years ago. The Wharfe was apparently under the radar until our campaign. (b) Water quality The EA claimed the water is in good condition, (as set out under the Water Framework Directive) at our first Town Meeting (February 2019), then subsequently confirmed it is Moderate. Our own review of the data shows it is Moderate. (a) The EA monitors for nutrients. (b) No-one monitors the faecal bacteria concentration in sewage effluents, either treated or untreated. We pressured the EA into monitoring water quality at Ilkley which they instigated monthly in 2019 for a 12-month period upstream and downstream of the sewage treatment works, but they did not include faecal bacteria monitoring. Prof Rick Battarbee from the ICRG developed the UK’s first Citizen Science river testing protocol for faecal bacteria and put it into action. This demonstrated the severity of the pollution coming both from treated and untreated sewage effluent discharges The EU Bathing Water Directive 2006/7/EC provides the following 90 percentile values for faecal bacteria in water of sufficient quality for bathing Parameter Excellent Sufficient2 quality1 Intestinal enterococci (cfu/100 ml) 200 330 Escherichia coli (cfu/100 ml) 500 900

As you can see from our testing when the river is in low flow the river quality far exceeds this minimum standard downstream of the sewage works (i.e. treated sewage outflow). In low flow conditions, high concentrations are caused by faecal bacteria from the treated effluent. Ilkley Clean River Group WQR0084

Upstream tributaries, especially those in , also contain high concentrations of faecal bacteria (and nutrients) from livestock and septic tanks (yellow) causing poor water quality in the becks in turn contributing to the pollution load on the main river through Ilkley. We found that upstream sewage sources (from the village of Addingham) were more important than agricultural sources, although agriculture caused high concentrations in tributary streams.

(c) The consent limit The consent limit was set in 2002 (effective from May 2021). However, climate change, population growth, and changes to the sewage infrastructure mean the consent limit is not fit for purpose. It should be set so that the sewage works complies with the Urban Waste Water Treatment Directive (UWWTD), spilling only in exceptional circumstances. The current consent is in effect a license to pollute. Ilkley Town Council (ITC) wrote to the Environment Agency asking for a change in the consent limit to realign the storm water discharge levels. ITC were told that a permit alteration would only be made by the National Permitting Service in response to evidence of adverse environmental impact which was not currently (in the eyes of EA) established. The Environment Agency apparently did not wish to change the consent as they didn’t think the level of discharges were unacceptable. (d) Legislation Raw Sewage Discharge should only happen under extreme, unusual and unpredictable conditions to be compliant with the UWWTD (1991). 3. Bathing Status Application for Bathing Status required: • Evidence of owner support (for us that was Council) • The survey of usage (counting people paddling, playing, swimming and using the riverbank over the whole bathing season and submitting the highest 20 days covering a mix of weekends, holiday days and weekdays) • A list of facilities (for us that included toilets, parking, refreshments, lifebelts) Ilkley Clean River Group WQR0084

• A local consultation (for us that was a Town Meeting – circa 100 ppl; an online survey >500 people; Local council meetings and letters of support from stakeholders (business, community groups) Defra then also undertook a consultation • 1046 private individuals and 27 organisations responded, 998 supported designation and 75 opposed. This is the highest response Defra has ever had to a public consultation Bathing status secures Ilkley  Weekly testing by the EA to assess water quality  Signage about Water Quality and any risks to bathing for the Bathing Season (May to Sept)  A Management Plan for the River And we anticipate investment to solve the pollution problem. The EA has told us Ilkley will be designated as poor water quality (Town Meeting March 2021). 4. Regulation, Governance and Accountability We have found that the agencies (EA and YW) were not in tune with public opinion. The overring story at the outset was that (a) the public knew what was going on and (b) they wouldn’t want to pay for any changes. ‘There isn’t enough money’ was the persistent response to our campaign. In fact, YW continues to say the solution will have to be paid for by the public (Town Meeting March 2021). The turnout at our public meetings (we have had 4 with circa 100 people each time) demonstrates local concern as does the national media coverage. In our experience we were not treated as customer (by YW) or owners (by the EA). There is no accountability to the public as the payer from any of the agencies involved in the issue. We have now met with the EA CEO, Ofwat Board, CCW members of the Storm Overflow Task Force (SOTF). We do not receive any updates on their activity in relation to the issues in Ilkley or nationally. The SOTF public representation is through Blueprint for Water but we do not know how they represent the public or engage with the public. There is no accountability back to local people who are paying or all aspects of water services and regulation through bills and taxes. Clearly there have been illegal incidents at Ilkley in relation to Manhole spills. It has taken our campaign to identify these. They are a result of poor maintenance of the sewage system. However there seems to be no clarity from the regulators about what a properly maintained sewage system looks like nor prosecutions or regulatory oversight of the maintenance of the system. Ofwat tells us (email 26th March 2021) “..we don't prescribe exactly how companies manage and maintain their assets. For example, there isn't a “minimum expectation” document companies’ operational day-to-day activities must be checked against by us.” In addition, “Yorkshire Water has around 32,000 km of sewer and it is our job to ensure it has efficient cost allowances for managing and maintaining them all.” We do not know how that level is set or if YW is compliant. Clearly what was set for Ilkley is not enough given the poor quality of the infrastructure. Ilkley Clean River Group WQR0084

In relation to the tributary pollution upstream of Ilkley. The rules to prevent pollution from agricultural land were published in 2018 (https://www.gov.uk/guidance/rules-for-farmers- and-land-managers-to-prevent-water-pollutiondischarges). The EA has a duty to enforce these rules. We cannot see evidence of that happening. This May YW will hold its first engagement meeting with Ilkley people. The Solutions Restoration of the Wharfe to high quality status along its entire length requires 1. Stronger national legislation by government (or enforcement of the UWWTD) 2. Commitment to enforcement by the EA 3. Investment in infrastructure by YW 4. Collaboration with the public For Ilkley the solution is: 1. A raise in the consent limit so that the storm overflow spills within the limits of the UWWTD. 2. Signage where the river is polluted so people are not putting themselves at risk in ignorance. 3. Prosecution / Management of pollution incidents 4. Water testing at all areas of usage 5. De-combining the system so that enough rainwater goes into the river and sewage goes to the treatment plant to be treated to be compliant with the new consent limit 6. Basic maintenance for infiltration, overflowing manholes, CSO provided with EDM and grills; and Improved treatment of ‘treated’ sewage e.g. UV disinfection and phosphate stripping to reduce pollutant contents. And in terms of accountability 1. Industry that treats the public as customers with local consultations and discussions, acts with a duty of care for our country’s environment, and invests in the long-term sustainability of the industry. 2. Regulators that are accountable to the public actively monitoring water quality and industry behavior
