Defining Investment, Funding, and Financing

The term “investment” is generally used to describe the economic value creation processes in which productive assets yield benefits over a future period. In the water context, investment therefore also includes the funding and financing perspectives (Fig. 1). Funding corresponds to income or cashflows that water projects generate which mainly comes from “3Ts”, which stands for tariffs, taxes, and transfers (Tool D2.03). Financing, in turn, refers to accessing resources for capital investments and covering operational and maintenance costs which are paid back with funding sources. The choice of funding and the flows of financing depend on political environment, regulation framework, institutional arrangements, as well as conditions of capital markets. Funding and financing are mutually dependent when efficient finance reduces the funding requirement for water-related projects, and credible funding streams help secure low-cost finance (WWC and GWP, 2018).

The cost of this investment needs to be funded in various ways through private and public funds or a mixture of both – charging water users, investments from government budgets, and external aid. Most of the water infrastructure investment traditionally comes from the public domain. However, in recent times, there is a growing involvement of private commercial entities in sharing these costs (e.g., using water tariffs to protect watersheds through investment vehicles such as water funds). 

Full-Cost Recovery Principle

Stemming from one of the Dublin Principles that water is an economic good, the concept of full-cost recovery should be integrated into the decision-making of the water-related investment process. The full cost of providing water consists of the full economic cost and the environmental externalities, which are not easy to assign a monetary value to. Estimating the full economic cost may be the basis to start with, including full supply cost (operating and maintenance expenditures and capital charges), as well as the opportunity costs and the economic and environmental externalities (Fig. 2).

There is a need to ensure that water resources management agencies and water utilities have resources to be financially independent for them to reach the desired level of effectiveness. As a minimum, full supply costs should be recovered to secure sustainability of investment. 

Dublin Principles state that water should also be taken as a social good, which generates social concern due to high supply costs. Marginalised populations whose incomes cannot afford to pay for full-cost recovery tariffs are in need of direct subsidies based on distributional decisions. Targeted subsidies need to take into account adequate revenue collection systems, mechanisms to identify the vulnerable groups, as well as the capacity to monitor and evaluate (Agarwal et al., 2000) – all of which are characteristic of a strong governance system. 

 

Governance as a Prerequisite

Underinvestment in water is caused not only by a mismatch between finance and projects but also by the institutional instability, which hinders bringing about a favourable setting to obtain long-term returns for either public or private investors. Successful water projects with stable long-term flow of returns and high social outcomes depends on delicate institutional designs (Guerrero et al., 2016). Robust institutional arrangements and participation (Tools B) can protect consumers and investors, enhance efficiency, and help with risk sharing – all of which promotes the long-term financial sustainability in the water sector (Fig. 3).
