Water charges are a widely used economic instrument implied mainly by federal governments to better control water use and water pollution by imposing a price on the use of the environment. The goal of such measures is to internalise negative externalities related to water use. Charges can be placed on emissions, users, the product, or on administrative services. Apart from influencing the amount of consumption, water charges can also activate innovation processes.
A charge can be defined as a ‘price’ paid on the use of the environment (HELMER & HESPANHOL 1997). As a type of water pricing, water charges can be related to both the use as well as the pollution of water. Besides their cost recovery element, they may also include demand management (see also water resources assessment, water balance estimation, demand creation, water allocation, tradable water rights, subsidies, and water pricing) to stimulate certain behaviour (SAVENIJE & VAN DER ZANG 2002). The outcome of water charges is a higher price, which (following market forces) reduces the demand for water or water pollution.
The Economic Model
Charge systems are one of the most frequently used economic tools to reduce the negative effects of over-consumption of water as a resource (other widely used economic measures are: subsidies, tradable water rights and water pricing).
The aim of charges is to reduce the demand for or the pollution of water by imposing a fee or tax on the consumer (opposed to the creation of an incentive for innovation by promoting money for a defined action or inaction of the consumer). Firms will reduce the consumption or pollution of water if behavioural change is less expensive than paying the charge. To reduce the amount of consumption, firms can either produce less or develop and improve new, more efficient production technologies. Charge systems therefore also place incentives for innovation. Furthermore, with the collection of charges, the government can raise increased revenue to redistribute (STAVINS & WHITEHEAD 1992).
Types of Charges
Four main types of charges can be identified (adapted from HELMER & HESPANHOL 1997):
- Emission/effluent charges: Based upon the quantity or quality of the discharged pollutant.
- User charges: Include for example fees paid for the use of drinking water and wastewater treatment facilities. They may be variable (e.g. increasing, decreasing or uniform volumetric), fixed or a combination of the two (see also water pricing).
- Product charges: Charges levied on products that are harmful to surface or ground water (e.g. pathogens, fertilisers, pesticides, lubricant oils, see also pathogens and contaminants).
- Administrative charges: Fees paid to authorities for such purposes as chemical registration or financing licensing and pollution control activities.
The implementation of charges on water use and pollution imposes several requirements on regulators and the regulated community (adapted from ANDERSON 2002):
- Emissions or effluents need to be measured.
- An appropriate fee level needs to be set.
- The due amounts need to be collected.
- The collected amounts need to be allocated.
There are several factors hindering or facilitating an enabling environment for the implementation of charges. They contain amongst other the creation of policies and a legal framework, building an institutional framework, as well as strengthening enforcement bodies.
Implementation Differences to Tradable Water Rights
The applicability of economic measures depends on both the specific environmental problem as well as the particular objectives of public policy. Differences in the implementation effects of charges to tradable water rights are (adapted from STAVINS & WHITEHEAD 1992):
- Charges do not impose a fixed level of consumption/pollution, but rather create an incentive for less consumption or pollution by providing an economic benefit.
- The monetary resource transfer is private-to-public because the charges are levied by the state (opposed to private-to-private between tradable water rights).
- The costs on public and industry are more explicit compared to tradable water rights, because the user does not perceive them as being rights to pollute or use, but rather as restrictions.
- Charges do not adjust automatically for inflation.
Charges are less susceptible to strategic behaviour of firms: If one firm holds a great part of the available permits in a water rights system, its activities may distort the price of permits.
Water treatment and collection charges as well as charges on pollution of water have been applied in most industrialised countries, having produced positive outcomes in terms of revenue raising and pollution control (HELMER & HESPANHOL 1997). The effectiveness and efficiency of their applicability depends strongly on the given circumstances and can be enhanced in combination with other market-based instruments (such as tradable water rights and subsidies). Implementation problems presumably occur if the institutional capacity is weak, if there is inadequate institutional co-ordination, economic instability, and government or polluter resistance or inertia.

Water Pollution Control - A Guide to the Use of Water Quality Management Principles
This document is rather old, but its publication was a milestone as it demonstrates WSSCCs capacity to bring together water and sanitation professionals from industrialised and developing countries to formulate practical guidance on a key issue of the day. Mainly regulatory, financial and technical aspects are discussed and illustrated with an extensive collection of case studies from the developing world.HELMER, R. ; HESPANHOL, I.

Water as an Economic Good and Demand Management. Paradigms with Pitfalls. International Water Resources Association
This paper argues that water pricing should primarily serve the purpose of financial sustainability through cost recovery. Instead of economic pricing, there is a need for defining a reasonable price, which provides full cost recovery but which safeguards ecological requirements and access to safe water for the poor.SAVENIJE, H. ; ZAAG, P. van der (2002): Water as an Economic Good and Demand Management.

Sanitation surcharges collected through water bills: a way forward for financing pro-poor sanitation?
This discussion paper is a situation review of sanitation surcharge systems in African cities, focusing on systems designed to raise revenues for improving sanitation in low-income districts. The review considers existing pro-poor surcharge systems in Lusaka and Ouagadougou; systems that cannot currently be considered pro-poor, in Dakar, Beira, and Antananarivo; and the special case of Maputo, where there is ongoing debate about how a surcharge might be introduced.WSUP (2012): Sanitation surcharges collected through water bills: a way forward for financing pro-poor sanitation?.
