Lack of access to clean water and sanitation is a major cause of illness and death globally. Water management is therefore a central public health question. There are many models in operation, including public private partnerships, and transnational water companies are involved globally.

A British water management company ('Royal Water' NB - this company doesn't really exist) is in negotiations for a water management agreement with the City of Nairobi. The agreement is being negotiated with the intention of improving water access in Kibera, which is a very large and poor area of the city with considerable water and sanitation problems. The company will be responsible for water infrastructure and billing. As part of its plans:

The company will improve communal access taps.
To help pay for the work and reduce waste, water pre-payment meters will be installed on the communal taps.
Each household will be provided with a pre-payment card which must have a certain amount of credit to operate communal taps.
30 litres of water per day is permitted to each household for free.

Your task, as an external team of consultants, is to develop an outline human rights impact assessment of the plan at these early stages of development. Your focus is the right to health.
