Practise of Regulation in the water and sanitation sector
All countries regulate the water and sanitation sector, but the width and breadth of regulation varies and in part depends on how service provision is structured. In the case of private operation such as in the UK and Wales, there is often a strong and independent regulator. Where the services are publicly owned and operated, the regulatory function is often less well developed and tends to be in the national ministry rather than an independent agency.
Almost inevitably, the water regulator's mandate covers the areas of finance (price of water), but it may also include tasks in the areas of public health (water quality), environment (discharges from operations) and social justice (service provision to the poor). The latter three areas may also be covered by line ministries such as Health, Environment and Social Affairs.
Over the years, regulators have evolved and so have their activities. Typically, the regulator issues the operating license, ensures the implementation of government policy, sets the water tariff and monitors performance. The UK’s OFFWAT is probably the first and better example of a well-equipped and empowered regulator that has powers to request and ultimately enforce action by the private operators. Other regulators are less well-resourced or have more limited powers or find difficulty exercising their powers, in which case their function is often limited to the issuing of operating licences and the monitoring and comparing of performance of the licensed operators.
Setting up and operating an effective regulating agency is anyway a challenge and the reality is that the regulated operators almost invariably have more resources at their disposal than the regulator has, and that is even more so if the local operator is part of an international conglomerate. In addition to this imbalance in resources, there is the inevitable information asymmetry that plays in the hands of the operator. To be effective despite these imbalances, the regulator needs strong backing from the government and the general public and needs to have the attention of the media. Even then, a less powerful regulator can always play an important role by sharing information on the performance of the water companies with government, the general public and other stakeholders. This information can be about progress by the sector against plan or about the performance of individual operators. With regard to the latter, having multiple water companies operating in the same regulatory (usually national) environment is to the advantage of the regulator. Not only does it allow the regulator to show the performance of the regulated companies against the same set of key performance indicators and even rank them on the basis of this performance, but it also allows the regulator to induce comparative competition and the setting of performance benchmarks.
The table below is based on the latest annual report by WASREB - the Kenyan water regulator - and shows the performance of the group of 87 Kenyan water companies against the national benchmarks for the nine key performance indicators. It shows that the sector is facing significant challenges in 5 key performance areas: water coverage, hours of supply, non-revenue water, personnel expenditure and cost recovery.
