The financial statements have been prepared in accordan￿ with the accounting policies set out in nole 1 to the financial statements and comply with the Charity's Constitution dated 1 November 2015 and "Accounting and Reporting by Charities.. Ststement of Recommended Practice applicable to charities preparing their accounts in accordance with the Financial Reporting Standard applicable in the UK and Republic of Ireland (FRS 102)" (effective 1 January 2019). Objectives and actlvities To prevent and relieve poverty and sickness and promote the good health of people anywhere in the world by developing their and their waler providers capacity to sustsinably use and develop groundwater resources. Our Mission Groundwater Reliefs mission is to alleviate poverty and suffering through working wth others to provide safe and affordable water supplies. Howwe work We undertake this mission through a core team of staff, and a global membership of groundwater experts. We engage our expertise wilh organisalions and government authorities whose remit is to provide safe, affordable and sustainable water supplies to vulnerable populations. We resource this work through.. charging consultation lees to International Non-Government Organisations {INGOs) and United Nations (UN) organisations who engage our seNices,' applying for grants with partner organisations- and the generous voluntary provision of support from OLtr membership. Core Values Throughout all of our work are four core values, which shape how we work and deliver our services. Integrity- We will not compromise on our Independen￿ and impartiality as we provide technical support. Professionalism - We deliver practical, high quality, technical expertise within the context and constraints of disaster response and low-income economies. Collaboration - We always seek to work as a ¢ollective. engaging the highest level of expertise. sharing dats and information. Respect- We respect those that work for us, those we work alongside and those we serve. Back round Over two billion people live in counlries where water supply is inadequate. This is due to economic challenges resulting in inadequate investment and development of waler supply infrastructure- and limited physical availability of fresh water. Groundwater constitutes 99% of the world's liquid fresh water and provides the source for 49% of global domestic water and 43 % of irrigation water. Groundwater resources are, however, poorly understood as they are inheritably difficult to see, quantify and manage. Significant investment in groundwater infrastructure is being squandered due to a lack of expertise. Groundwater resources are coming under increasing pressure due to over-extraclion. leading to dedines in groundwater levels. saline intrusion and decreases in surface water flow., and through pollution from industry, agriculture and poor waste management. Groundwater Relief (GWR) was set up in 2015 to fill the recognised skill gap within the humanitarian and development sectors. Through our global membership of groundwater experts, GWR provides organisalions wth specialist suppori to conceptualise, assess, develop and manage groundwater resources. We work with local water users, water providers, govemment and academia to build capacity, promote data sharing and equip local staff to deliver water to those most in need.

Conclusions relating to going concern In auditing the financial statements, we have concluded that the Trustees, use of the going concem basis of accounting in the preparation of the financial statements is appropriate. Based on the work we have performed, we have not identified any material Un￿rtaIntieS relating to events or conditions thal. individually or collectively, may casl significant doubt on the Charity's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.

We have nothing to report in respect of the following matters in relation to which the Companies Act 2006 requires us to report to you if, in our opinion- adequate accounting records have not been kept, or returns adequate for our audit have not been received from branches not visited by us- or the financial statements arè not in agreement with the accounting records and returns., or certain disclosures of trustees, remuneration specified by law are not made., or we have not received all the information and explanations we require for our audit. or the Trustees were not entitled to prepare the financial statements in accordance with Ihe small companies regime and take advantage of the small companies, exemptions in preparing the Trustees, report and from the requirement to prepare a strategic report. Responsibilities of Trustees As explained more fully in the statement of Trustees. responsibilities, the Truslees, who are also the directors of the Charity for the purpose of company law, are responsible for the preparation of the financial statements and for being satisfied that they give a true and fair view. and for such internal control as the Trustees determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error. In preparing the financial statements, the Trustees are responsible for assessing the Charity's ability to Continue as a going concern. disclosing. as applicable. matters related to going concern and using the going concern basis of accounting unless the Trustees either intend to liquidate the charitable company or to Cease operations, or have no realistic altemative but to do so. Auditor's responsibilities for the audit of the financial statements Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and lo issue an auditorfs report that includes our opinion. Reasonable assurance is a high level of assurance but is not a guarantee that an audit conducted in accordance with ISAS (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate. they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements. Irregularities, including fraud, are instances of non-compliance wth laws and regulations. We design procedures in line with our responsibilities, outlined above. to detect material misstatemenls in respect of irregularities, including fraud. The risk of not detecting a malerial misstatement due to fraud is higher than the risk of not detecting one resulting from error. as fraud may involve deliberate concealment by, for example. forgery, misrepresentation or through collusion. The extent to which our prO￿dureS are capable of detecting irregularities, including fraud. is detailed below. However, the primary responsibility for the prevention and deteclion of fraud rests with those charged wilh governance of the company and management. The laws and regulations identified as being of significance in the context of the charitable company are.. Compliance with the Charities Act 2011 and the CompaniesAct 2006.
