- Abstract
- Cascade Water Supply Systems (CWSS) are a type of rural water supply system used in many parts of the world such as India, China, Sri Lanka, South America, Iran, Iraq, Saudi Arabi, Korea, Peru, Egypt, Rome, Turkey, Greece, and Thailand. They are also known as Village Tank Cascade Systems (VTCS) & Cascade Systems (CS). CWSS is typically designed to collect runoff from upper forested catchment areas to provide to downstream areas and consists of a network of linearly inter-connected 'tanks' or storages, with the supply of water often supplemented from additional catchments downstream, along with groundwater resources and diversions from other sources such as rivers. As water flows from the upper regions to the downstream segments of the system, water is utilised for various purposes such as irrigation, drinking, bathing, and other household activities. The inflows and outflows result in changes in water quality in different stretches of these systems. This paper reviews the international literature surrounding CWSS, with a particular focus on water quality and associated issues. It has been found that despite the significant social, environmental, and economic importance of CWSS, and their existence for many centuries, there is limited information on water quality characteristics over space and time. Pressures such as population growth, intensification of agricultural practices, and changing climate, affect these systems as well. This review reveals that water quality is comparatively better in the upstream sections of CWSSs and progressively worsens downstream, with the data showing that the water quality in downstream systems clearly exceeds the WHO drinking and irrigation water standards. © Hydrology and Water Resources Symposium, HWRS 2022.
