Title: Water resources development strategy : methodology and assumptions for public water supply demand scenarios. Supplementary report no.1
Author: M.H. Sitton
Document Type: Monograph
This report is the first in a series of nine supplementary reports which provide supporting information for the National Rivers Authority, Water Resources Development Strategy document. "An Environmentally Sustainable Water Resources Development Strategy for England and Wales". The following paper details the methodology and assumptions which are employed to produce a set of nationally consistent demand forecasts for each Water Service and Water Supply Company in England and Wales. A multiple component technique is used for calculating current and forecast demand. Forecast scenarios are described by the combination of a suite of broad based assumptions about future demand. These forecast scenarios delimit the range of forecast between high and low and therefore indicate the predictive demand envelope. The base year has been taken as 1991 with the forecast horizon set at 2021. Regional variations relating to metering and leakage are recognised with companies being placed into two groups relating to their inclusion in various metering and leakage assumptions.
