Operation costs are the expenses related to the operation, maintenance and monitoring of the plant, once it was constructed. These costs will be incurred in a regular basis along the service life. Exemplarily, figure 2 shows the cost composition of wastewater systems in Germany divided up in capital and operation costs [ATV, 2003]. Easily it
OPERATION COSTS OF WASTEWATER TREATMENT PLANTS
Operation costs are the expenses related to the operation, maintenance and monitoring of the plant - Operation costs can amount up to 50 % of the total annual costs. - The evaluation of operation costs during the evaluation of of process alternatives is of crucial importance. Composition of total annual costs for wastewater systems in Germany
Detailed analysis of 47 wastewater treatment plants in Germany of 2,500 – 1,000,000 p.e. identified an energy cost saving potential between 5 and 100 % (average 34 %). Providing the realization of all proposed measures, about 2.3 m € could be saved per year [Kaste, 2003].

Operation costs are the expenses related to the operation, maintenance and monitoring of the plant, once it was constructed. These costs will be incurred in a regular basis along the service life. Exemplarily, Figure 1 shows the cost composition of wastewater systems in Germany divided up in capital and operation costs [ATV, 2003].
Energy consumption is a major contributor to the operation cost of wastewater systems and therefore is an important parameter for choosing a treatment technology. The costs for energy usually amount up to 10–30 % of the total operation costs. Energy costs include the consumption (and internal production) of electricity, gas, oil and district

Sludge treatment centres, treating sludge from several surrounding wastewater plants, may be required especially if thermal drying or incineration are likely options. Economic evaluation has to consider capital and operating costs of sludge treatment and transport and other costs associated with disposal.

The United States is not on track to meet the Renewable Fuels Standard (RFS2) targets for advanced biofuels production under the Energy Independence and Security Act (EISA) of 2007 (Biofuels Interagency Working Group, 2010). Our agricultural and forestry sectors can provide feedstock to support the fledgling industry (Perlack et al., 2005).

The World Nuclear Industry Status Report 2017 (WNISR2017) provides a comprehensive overview of nuclear power plant data, including information on operation, production and construction. The WNISR assesses the status of new-build programs in current nuclear countries as well as in potential newcomer countries. The WNISR2017 edition includes a new assessment from an equity analyst view of the
