Description:
Cost models for unit processes typically utilized in a conventional water treatment plant and in package treatment plant technology are compiled in this paper. The cost curves are represented as a function of specified design parameters and are categorized into four major categories: construction, maintenance materials, energy and labour. the cost curves are developed so that cost indices may be used to update cost estimates from the base year. These models can be used to assist in making decisions related to construction of new water treatment facilities or modification of existing water treatment processes to meet drinking water standards or provide improved water quality. they can also be used as a part of sophisticated economic evaluation such as the calculation of cost to benefit ratios.
