Water Demand Handbook
HR Wallingford, with funding from British DFID, in collaboration with Department for Water Development, Ministry of Rural Resources and Water Development, Zimbabwe, University of Zimbabwe, University of Zambia and University of Zululand
from the HR Wallingford Site
The Handbook for the Assessment of Catchment Water Demand and Use is aimed at organisations with an interest in water resources management at a catchment level in southern Africa. The Handbook responds to the growing need to balance supply-side and demand-side approaches to managing scarce water resources in river basins. It recognises that a plethora of research and methodologies are readily available to assist planners and managers to assess water resource availability in a catchment yet little is available to assist in assessing water demand and use. The Handbook aims to fill this gap by bringing together a range of methodologies, examples of their application, supporting information and key references.
The Handbook is structured as follows:
Introduction provides important definitions and an overview of water resources and water demand in southern Africa
An Introduction to the Principles of Managing Water at a Catchment Level
Environmental Water Demand and Use details methods to estimate instream environmental water demand
Agricultural Water Demand and Use
Rural Water Demand and Use
Industrial Water Demand and Use details methods to assess water use for a whole host of industries that are typically found in southern African
Urban Water Demand and Use includes methods to establish urban water demand and use including commercial and institutional demands but excluding industrial water demands. Typical per capita water consumption figures for urban areas throughout southern Africa are provided
Forecasting Water Demand and Use
River Transmission Losses outlines methods for assessing river transmission losses. Although river transmission losses are not strictly a demand it is important that they are taken into account when allocating water at a catchment level
Industrial Water Consumption Look Up Tables provides some 70 look up tables detailing typical water consumption figures for a wide range of industries.
The Handbook for the Assessment of Catchment Water Demand and Use has been produced with funding from the Department for International Development (DFID) of the UK Government under the Knowledge and Research (KAR) programme. The work has been carried out as a collaborative venture between HR Wallingford (UK) and the Department for Water Development, Ministry of Rural Resources and Water Development (Zimbabwe), University of Zimbabwe, University of Zambia and the University of Zululand, South Africa.
The Handbook is available for no cost.
