My village in Herefordshire's Golden Valley boasts its own water company - The Peterchurch Water Company - owned by the local residents who receive their water from it. The source of supply is a natural spring that flows into St Peter's Well on the side of the gentle valley through which the less-than-mighty River Dore trickles lazily before joining the Monnow, a tributary of the far mightier River Wye. Legend has it that while on his way to Rome St Peter himself consecrated the well and put in an immortal trout which remains the symbol for the village today.
Shaping landscapes physical and cultural
Water has of course shaped both our physical and cultural landscape for millenia. It occupies a defining place in our natural and social history and connects the two in the story of human civilisation. As the source of life and the most basic of human needs it has also held a special spiritual and symbolic significance in diverse cultures and beliefs. To many, access to water is a human right and to make an exclusive claim to something that falls unbidden from the sky and finds its own course through our landscapes is an offence to moral intuition. In all societies for all of history water has usually been viewed as a form of public property, freely available to all as a gift of nature or God.

Water, water everywhere but...
In the objectifying world inhabited by economists, water is viewed as a "good" or a resource - public or common pool respectively depending on the conditions of scarcity. In both cases it is either impractical or costly to exclude others from the use of a locally fixed supply of (usable) water. Pure public goods are usually provided by the state, since the "free rider problem" would ensure that they remain underprovided otherwise. State property is "owned" on behalf of the people. But once there is not enough to go around and if the state cannot exercise some form of control a tragedy nevertheless looms.
According to the economist's utilitarian instinct a problem arises when one person's use leaves less for the next person, which must be solved for the sake of overall human welfare. In this calculation, no-one can claim a natural right to water. A "property right" must be assigned or else accept the inevitable fate of any unowned resource for which there is "open access" (res nullius) - the so-called tragedy of the commons. Who should own the right to the benefits that water bring depends, in the economist's parlence, on the transaction costs assocated with each alternative. The most important of which is the cost of excluding others from it.

At least in theory. But it is one that is usually hotly disputed wherever it is proposed. To many, the commodification of something freely provided by nature is still a form of robbery. Exclusion is simply unjust. In the developing world tariff rises that have followed privatisation or partnership have often been met with public displays of opposition. Privatisation and reform of the water industry in Brazil in the 1990s was viewed with popular suspicion and dissent. During the next decade many multi-national companies pulled out of Latin America all together.
When Right Is Might?
A form of de-facto privatisation sometimes arises from a process of creeping encroachment, rather than a formal assignment of rights. Others are excluded from the resource not by an act of law or by contract, they are simply muscled out. We might regard this as an illegitimate appropriation of a right. Coca-Cola's bottling plants in India were blamed for drying farmers fields, lowering and polluting the water table. In 2007, more than 400 people in Varanasi protested at the district magistrate's office demanding that Coke's Mehdiganji plant, with its veracious demand for hundreds of thousands of litres of water, be shut down. The license of another Coca-Cola plant in Kerala in 2004 had already been revoked due to local water shortages and pollution blamed on the company.

Rights or Relationships?
Justice requires a search for an alternative that satisfies our moral intuition as well as distributional and procedural demands. Solutions inspired by neo-classical economic theory have centred on regulation or rights over public goods or common pool resources. When a large number of users have independent rights to the use of water resources, licensing and permitting are the controls through which use and access is distributed by the State. To many neo-liberals this is a second-best solution at best. At worst, it is a source of rent-seeking and government failure. Establishing private property rights in a market-based solution offer the hope of greater efficiency, safe and universal supply. In both cases, rights and duties have to be imposed and enforced by the state - a potentially difficult and costly task.

Collective action has been shown to be successful when a localised property right can be upheld over a relatively fixed or immobile resource with clearly defined boundaries and localised externalities. Where the transaction costs are lower than alternative institutional arrangements it makes more economic sense. It requires a small like-minded group of people who have commonly held rights over the resource but it is not possible to allocate an individual share of the benefits. Social capital, in the form of common values and trust, is a critical factor. Ostrom adds other communally determined institutional "design principles" for establishing rules: collective choice arrangements, monitoring, graduated sanctions, and a procedure for resolving conflicts. A common property regime (CPR) is therefore defined by a set of social relations, not simply by the assignment of a property right.
Corporate Water Responsbility

On the basis that you can't manage what you can't measure, both the Carbon Disclosure Project's water initiative and the Water Footprint Network are working to improve standards of measurement and reporting. Some major corporate users of water are going further by engaging stakeholders and building relationships with local communities. For example, Tanzania Breweries Limited (TBL), a subsidiary of SABMiller, held workshops with local stakeholders in Dar es Salaam, made a detailed study of the river basin, and drew up a set of actions to improve water efficiency in the area. These included educating farmers and working with local authorities to prevent leakages from infrastructure.

Meeting the challenge together

If private sector corporate interests are to be welcomed in resolving the water challenges of the future, new institutional arrangements will need to be designed in which there is a genuine commitment to building the local capacity to ensure they are sustainable. Real multi-stakeholder partnerships must include public and private actors, but also local NGOs, civil society organisations, as well as local communities. It requires all parties to define a shared goal and build trust by seeing the world through the eyes of others in Kant's kingdom of ends. Corporations will need to learn to properly understand the livelihood choices faced by the poor; their risks and vulnerabilities, not just its own.
The right to water may in a sense be assigned by the award of a license, permit, or the monopoly of a long term concession over vital infrastructure. But in any morally relevant sense, a right to a shared interest in water resources can only be secured by mutual consent and mutual obligation before it can be regarded as a legitimate right. It is through a normative ethic of discourse that the trust, shared norms and rules necessary for the stable collective or communal arrangements discerned by Ostrom can be built upon a solid bedrock of social capital. Working at a watershed scale isn't just about defining system boundaries by geography and hydrology. It is about forging relationships with the people that form part of the whole system. It is as much about the content of those relationships as the ecosystem services they share.
