 Funding for measures aimed at improving access to water and sanitation in areas without adequate services – especially areas inhabited by the poor – is provided by the Water Services Trust Fund (WSTF).The WSTF receives funds from the Government of Kenya and from donor agencies and directs them to the 362 poorest locations throughout the country (identified in collaboration with Water Services Boards).Since 2009 Kenya's largest mobile phone company extended its mobile phone bank transaction payment system M-Pesa to be used for the payment of water utility bills.
