Much of the content is based on the work done by WSP’s global rural sanitation team. Without their hard work and dedication on the ground, this publication would not have been possible. Contributions from Eduardo Perez, task team leader for WSP’s Scaling Up Rural Sanitation, Yolande Coombes, senior water and sanitation specialist, and Ian Moise should also be acknowledged. WSP wishes to thank peer reviewers from within its team, notably Malva Baskov- ich, Edkarl Galing, Peter Hawkins, Ari Kamasan, Nelson Medina, and Jan-Wil- lem Rosenboom for technical inputs; and Amy Grossman and Joan Taylor for managing content development and production. WSP also thanks.
