Costs of WASH Service Delivery - Introduction
The costs of water, sanitation and hygiene services include expenditure on construction of water and sanitation systems, operation and maintenance and eventual rehabilitation of infrastructure. It also includes training and support to service providers, cost of capital, and expenditures for monitoring, planning and policy making. They are often referred to as life-cycle costs; the costs of delivering water, sanitation and hygiene services indefinitely to a specific population in a particular geographic area.
Life-cycle costs are divided into six categories (see figure 1 below). These six categories are related to onetime expenditures on providing or upgrading a service, also known as capital expenditure (in green in figure 1) and recurrent expenditures (in blue in figure 1) on maintaining a service at its intended level.
