August 23, 2018—WaterAid is launching a new guide to help companies understand and measure the economic benefits of investing in water, sanitation and hygiene, and thereby make the case for further investment while also encouraging their supply chains to take action.

Diageo, Gap Inc., and Unilever, have championed this work with WaterAid and with support from PwC and ODI have developed the step-by-step guide, ‘Strengthening the business case for water, sanitation and hygiene: How to measure value for your business.’ The guide, endorsed by WASH4work, will launch at Stockholm World Water Week on Thursday 30 August.

At a global level, the economic case for investing in WASH is well-established – it is estimated that every dollar invested in sanitation returns $5.5 in increased productivity, while every dollar invested in drinking water supply returns $2.[1]

However, there is only anecdotal feedback and case studies exploring the benefits to individual businesses, such as reduced absenteeism, increased loyalty, and improved productivity. While this is a useful starting point, companies require more robust evidence to demonstrate the financial value in order to strengthen the business case for investing in WASH and drive action on a wider scale.

WaterAid’s new resource responds to the growing need for the evidence that improving water, sanitation and hygiene facilities should be more than a philanthropic measure or means to tick a corporate social responsibility box; it should be a core business priority.

WaterAid's U.S. CEO, Sarina Prabasi said:

Businesses are crucial in bringing about the step change needed to end the global water crisis. The social, moral and macro-economic case for investing in water, sanitation and hygiene is clear. In order to drive transformational change, we need more companies to leverage their tremendous influence across the supply chain. This new guide will provide the evidence businesses need to scale up action.

I applaud our corporate partners Diageo, Gap Inc. and Unilever, who are investing in this crucial work. Every day the water and sanitation crisis continues to claim lives and hold people back from achieving their potential. We don’t have a moment to spare.

WaterAid recently worked with a tea estate owner in Sylhet, Bangladesh, to improve access to clean water and toilets in the tea gardens and the surrounding areas. Tea picker Bina, 45, used to walk for an hour each day to collect water from the well, as well as using water from a nearby stream, which was contaminated. Bina and her children were often sick; resulting in missed work and a loss of income.

Bina says the new pumps and latrines have made a huge difference in her life, and have benefitted the estate too. A tea garden manager said: “Waterborne diseases have reduced so we pay fewer sick days. Efficiency has increased, definitely.”

WaterAid’s new guide will help measure the impact of such interventions to strengthen the case for future investment internally and with external suppliers. Crucially, sharing the evidence and learnings can help catalyze action across the business community.

Through a new HSBC-funded project on Sustainable Supply Chains in the apparel sector in India and Bangladesh, the new guide will now be implemented, and the results shared to spur others into action.

Diageo has committed to applying it in Ethiopia and potentially also in Tanzania. The company also has a ‘Water Blueprint’, in which it wants to achieve three targets by 2020. It aims to reduce water wastage through a 50% improvement in water-use efficiency; safely return its wastewater to the environment; and replenish the amount of water used in water-stressed areas. It also wants to ensure appropriate access to clean water, toilets and hygiene for all its employees.

Gap Inc. and Unilever are also pursuing opportunities for using the guide. Gap Inc. has been working with global supply chains and suppliers to adopt more sustainable manufacturing practices. The company’s climate policy aims to address emissions beyond brick and mortar stores by actively working with suppliers to help reduce water and greenhouse gas emissions.

Unilever has also prioritized WASH with fully integrated water, sanitation and hygiene in its own workplace and manufacturing sites, through safety, health and environment standards, as well as ensuring external suppliers have access to clean water and toilets.

WaterAid will present the guidelines at Stockholm World Water Week, which runs from 26 – 31 August and brings together experts from the fields of science, business, and policy to discuss water-related challenges.
