Long-Term Financing in Water and Waste Projects
A water treatment or waste management facility's revenue usually comes from a regulated tariff; how that tariff is set and how often it is updated directly affects the project's financeability.
The importance of the tariff mechanism
The lender examines how often and by what formula the tariff passes through cost increases (inflation, energy prices, operating expenses).
An automatic, predictable tariff update mechanism provides a far stronger financing footing than one subject to political discretion.
The role of the regulator
In the water and waste sector, the regulator's independence and the predictability of its decisions directly affect how a lender prices country and sector risk.
In markets where regulatory decisions shift with political cycles, lenders usually demand a higher risk premium.
Financing tenor for long-lived assets
Water and waste infrastructure assets can have an economic life of thirty years or more; this allows loan tenor to be set longer than for other infrastructure types.
A longer tenor reduces the annual debt service burden and eases pressure on the tariff.
Environmental compliance obligations
Water and waste projects are usually subject to strict environmental standards; future tightening of these standards can create additional investment needs.
The financing structure can be built with some flexibility for such regulatory changes, such as an additional credit facility or reserve account.
The role of development finance institutions
Given their social impact, water and waste projects are among the priority financing areas for development finance institutions, which usually offer longer tenors and better cost than the banking market.
This financing usually comes with technical assistance and environmental/social standard compliance requirements.
InfrastructureIn infrastructure the financing tenor approaches the life of the asset, so the structure has to be thought of in twenty-year terms from day one.
