With regard to wastewater management, there is a growing use of separate charges for wastewater collection and for wastewater treatment, with the latter increasingly based on the pollution load of industrial effluents, thus better reflecting actual treatment costs. A variety of water funds aim to secure funding for water infrastructure. For the financial year 2010, the U.S. Environmental Protection Agency (EPA) requested USD 3.9 billion for Clean Water and Drinking Water State Revolving Funds (SRFs) for funding water infrastructure projects.
