Abstract
A traditional water supply network has a single water supply reservoir supplying a neighbourhood of households via a reticulation network designed for peak flows.
Storage tanks at each household (distributed storage) can be utilised to act as buffers between continuous supply of average flows and intermittent demand of peak flows.
This results in the water supply infrastructure needing to cater for average flows only. This research project examines potential savings that can be made to water supply
infrastructure when distributed storage (household tanks) is utilised.
An isolated network is modelled for both the traditional design scenario and a design incorporating water tanks at each point of supply. The water supply network is modelled
using Pipes++ software package. The reticulation layout is identical for both designs and hydraulic conditions, such as pressure available at the water supply source, are kept
the same to isolate differences to those between peak and average flows only. Comparison is made in terms of required pipe sizes and costs.
Pipe diameters and construction costs of the distributed storage network are between 50% and 60% less than that required for the traditional network. The larger percentage
of savings were made in the single distribution main linking the subject site to the source of water supply approximately 1.2 kilometres away.
The costs of water tanks and pumps for each household outweigh the savings made by reduction of reticulation pipes. When tanks and pumps are already provided for re-use
of rainwater, the distributed storage network provides significant savings.
The prospective merits justify and highlight the need to investigate other characteristics and aspects of distributed storage networks including incorporating water tanks for reuse of rainwater, water quality, minimum pressure requirements, energy use, clustered networks, fire fighting requirements and different sized communities.
