Modernizing Water Distribution Networks

Outlook on Agriculture, 2012
In many arid and semi-arid countries, traditional irrigation schemes have been modernized, with open channel networks replaced by new on-demand pressurized systems. In this study, this conversion is evaluated using performance indicators derived both before and after the modernization of an irrigation district (Bembézar MD) in Andalusia, southern ...

Potable Water Distribution Network Optimization

2023
Nowadays, potable water supply has become a problem, involving different aspects such as water quality, pollution, pipes' quality, supply and demand of drinking water, water leaks, and supply cuts, among other aspects that have complicated the efficient use of potable water in urbanized regions.

Sequential Monitoring of Water Distribution Network

IFAC Proceedings Volumes, 2012
Abstract Monitoring drinking water is a public health problem because water is essential for human life. A typical modern drinking water distribution system includes a water purification plant, water towers, water tanks, pumps and pipes. Many procedures are developed for monitoring water quality in water treatment plants.

Optimal Design of Water Distribution Networks

Journal of the Hydraulics Division, 1978
A method for the optimal design of water distribution networks is presented. It defines the least-cost solution for a closed network, using standard diameters on the market. It can take into account the branches whose diameter value are assigned (existing); the range of velocities in the pipes and of the hydraulic heads can be imposed. And, lastly, the

Distributed Reference Management Strategies for Networked Water Distribution Systems

IFAC Proceedings Volumes, 2011
Abstract A distributed constrained supervisory strategy for large-scale spatially distributed systems is presented and applied to a networked water distribution system. The aim is at reconfiguring, whenever necessary in response to different supply downstream demands, the nominal set-points to the tank water levels so that all prescribed coordination ...

Decomposition of Water Distribution Networks

A I I E Transactions, 1976
Abstract This paper generalizes the class of design problems for water supply systems which can be solved by mathematical programming. The goal is to design a least cost water supply system to satisfy minimal pressure head requirements at specified rates of usage for multiple customers.

Water Distribution Networks

2014
A water distribution system is a complex assembly of hydraulic control elements connected together to convey quantities of water from sources to consumers. The typical high number of constraints and decision variables, the nonlinearity, and the non-smoothness of the head—flow—water quality governing equations are inherent to water supply systems ...

Hydraulically Predictable Water Distribution Networks

Civil-Comp Proceedings, 2009
There is a considerable amount of uncertainty associated with the design and operation of water distribution systems. These include: long-term projections of the growth in demand; the spatial distribution of the nodal demands coupled with diurnal and seasonal consumption patterns; variations in electricity/energy tariffs; bursts and component failures;

Optimization of water distribution networks

Journal of Hydraulic Research, 1996
In this study, a computer program is developed which enables us to design a water distribution system which satisfies all constraints including pipe diameters, low velocities, and nodal pressures with a minimum total cost. The hydraulic analysis of the water distribution system is performed by the Newton-Raphson method.
