Italy’s first water sector public-private partnership and its implications for today

The intake of the Villoresi irrigation canal is a monumental structure of classical beauty: it tames the blue waters of the River Ticino, just below the outlet of Lake Maggiore, and quenches the thirst of 85,000 hectares of otherwise dry land to the north of Milan.

This imposing project was designed, financed, and built entirely with private capital between 1877 and 1890. A 90-year concession was granted by the King of Italy only 15 days after receiving the investment proposal from the original investors. In 1918, farmers formed a consortium of water users and took over the concession and the infrastructure.

With such a head start in the development of water sector public-private partnerships (PPPs), one would imagine that in Italy such contracts would be widespread and well known. In fact, the opposite is true, and the political debate around the meaning of private sector participation in water services is as heated, alive, and confused  as ever. A leading national newspaper printed, in the same edition, one article broadly supportive of a popular movement against private involvement in water service providers, and another article denouncing a case of pollution by a (public) water company that had been discharging untreated sewage and hazardous waste in the Bay of Naples.

Misunderstanding and strong opinions are not limited to Italy. Regardless of location, government officials wishing to implement a water PPP must begin with realistic expectations . Here are a few:

Private investors cannot miraculously break the economic balance in play among tariff revenue, operating costs, subsidies, and cash available for investments. It is unreasonable to expect private operators to transform, in a few years, a loss-making, subsidy-dependent water company incapable of maintaining its asset base. It is even more outrageous to expect them to transform into a profit-making making company capable of financing new investments, without a tariff increase to reward the capital investment or a capital grant to subsidize tariff levels.

Perhaps most important is that private-sector participation and investment in the water sector is not a substitute for sector reform and regulatory oversight, which is invariably a prerogative of the government. For the private investor to produce strong results, its public sector counterpart, the regulator, needs to be equally empowered . Local sensitivities and the specific technical and economic conditions of each operation require careful and continuous adaptation. This is the lesson from the 120-year-old Villoresi irrigation canal , which was successfully designed, financed, constructed, and operated for many years by private investors, and is now successfully owned and operated by a consortium of public entities.
