Safe water can be provided in many ways. The hypothetical case study considered ceramic filters that can be operated in the home and the more elaborate ultraviolet (UV) filters that can be purchased by a community or franchisees who would then sell safe water to households.

The price of the water to the consumer would be low and thus affordable to most families without assistance, and the savings on medical services would be substantial.

The Nigerian government has already stated its commitment to this end.
