The huge scale of the global water and sanitation crisis means that inevitably there are many charities across the world trying to tackle it. However, attempting to merge these thousands of groups and work as one organisation would pose many challenges in logistics and practices, risking inefficiency. There are already coalitions and networks that bring together and oversee many charities, and we regularly take part in partnerships of this kind for specific projects. Such collaborations help to eliminate overlap and duplication of effort in areas where more than one charity may be working, and create opportunities to collaborate and share knowledge and ideas. As a leader in the sector, our successful working practices are often cited by other organisations in their own work. For this reason, we readily share information through such resources as our Technologies page.
