The work is carried out in cooperation with 26 local women’s self-help groups. Each group chooses a sanitation ambassador. The ambassadors and group members are trained in the benefits of sanitation, the usage of ecological fertilizer, soap-making and menstrual hygiene.

An ecological dry toilet is constructed at the home of each ambassador, and it serves as an example toilet for the community. The construction costs are shared between the project and the ambassadors. The price of the dry toilets is equivalent to pit latrines commonly used in the area, making them reasonably affordable for local communities.

The ambassadors and construction workers get training in entrepreneurship, for example soap selling, and construction of dry toilets.

Wash and Grow! reaches through 24 women’s self-help groups 715 women and 4-5 constructors. The project benefits also their family members, approximately 3500 people. Through communications campaign and cooperation with the health officials the project reaches altogether 87000 people living in the area. 

The project is implemented together with the Mifuko Women’s Development CBO, a non-governmental organisation founded in March 2021 consisting of 24 women’s self-help groups from the local area. Other partners are Mifuko Oy which has operated commercially in Kenya since 2009, the Global Dry Toilet Association of Finland, and Ukumbi, a nonprofit specialised on sustainable architecture. The Wash and Grow! project also cooperates closely with the local administration in Kenya.
