Sectorización de Redes
Las grandes redes de distribución no pueden gestionarse de manera eficiente sin dividirlas en zonas y subzonas (DMA) y prestar una atención significativa al tema de la gestión de la presión. La gestión de la presión se considera la actividad de gestión de fugas más beneficiosa, importante y rentable. Estas medidas son esenciales para obtener una visión global del consumo de agua y de las pérdidas de agua en las diversas zonas de la red

When is a DMA not a DMA
How many times do we think that we have considered all the dependencies necessary to demonstrate to various regulatory bodies that all our data is validated and proved to be correct only to find that a reported burst main does not appear to manifest on the Daily Measured Flow (DMF) or even worse, that the burst when repaired does not significantly reduce or impact on Minimum Night Flow (MNF
Using practical predictions of Economic Intervention Frequency to calculate Short run Economic Leakage Level
The development of quick and practical methods for calculating economic leakage levels is a stated objective of the Water Losses Task Force.
Tailoring the Specifications for Pressure Reducing Valves
The authors have noticed that water utilities around the world are experiencing difficulties when it comes to the specification of pressure reducing valves (PRVs).
Systematic Approach in Analysis of Pressure, Burst frequency Realationship
Purpose of this paper is to present for one representative segment of the water distribution network - DMA (District Metered Area) results and benefits of pressure reduction and control and effects on pipes burst frequency.
Single and Double Chamber Valve - Design Comparison
Hydraulic control valves are utilized for implementation of specific control functions in the water supply systems, such as pressure & flow control, remote open\close, water level control in tanks and reservoirs and many others.
Searching for N2- How does Pressure Reduction Reduce Burst Frequency
Pressure management schemes are becoming increasingly popular - mainly because of the reduction of leakage in general and the reduction of background leakage in particular.
Recent developments in predicting the benefits and payback periods of introducing different pressure management options
Substantial advances have been made by the IWA Water Loss Task Force members in the last few years in the development of practical water loss management methods, including the benefits of active pressure management, calculation of economic intervention frequency for active leakage control, and economic levels of leakage.
PRV Use For Leakage Reduction- Various Technical Solutions
The use of pressure reduction, as a method for reducing water-loss and labor cost in municipal water supply system, is generally accepted in the industry.
Progress in practical prediction of pressure- leakage, pressure- burst frequency and pressure- consumption relationships
Substantial advances have been made in the last decade in the development of practical methods for understanding and predicting how leakage rates and burst frequencies in distribution systems, and some elements of consumption, are influenced by pressure.
Pressure management extends infrastructure life and reduces unnecessary energy costs
Pressure management encompasses several approaches and has a number of important benefits; it has been referred to as “the preventative method par excellence” of water loss management.
Leakage Reduction Through Pressure Management In Khayelitsha Western Cape, South Africa
Khayelitsha is one of the largest townships in South Africa and is located approximately 20km from Cape Town on the Cape Flats (a large flat sandy area at or near sea level).
Leakage reduction through pressure management in Khayelitsha-Two years down the line
The Khayelitsha Pressure Management Project has been well documented and widely publicised since it was commissioned towards the end of 2001.
Leakage reduction by advanced pressure control- khayelitsha, South Africa
Khayelitsha is one of the largest townships in South Africa with a population of approximately 450,000.
Large scale pressure management implementation in the City of Cape Town
Water supply to the City of Cape Town has been a problem for many years and several large and expensive water transfer schemes have been commissioned to keep pace with the ever-increasing demands.
Including the effects of pressure management in calculations of Short-Run Economic Leakage Levels
During 2005 and 2006, research and publications by IWA Water Loss Task Force members have shown, beyond reasonable doubt, that management of surges and excess pressures can have a significant effect of the frequency of new leaks and bursts in water distribution systems.
Implementation of pressure management in municipal water supply systems
Pressure management is one of the most important Water Demand Management interventions that can be implemented by a water utility in its efforts to reduce leakage.
Experience and results achieved in introducing District Metered Areas (DMA) and Pressure Management Areas (PMA)
This paper aims to demonstrate that through the practical application of advanced methodologies, a significant improvement in the efficiency of distribution systems is not only feasible, but can also provide an example to encourage other utilities to improve their performance.
City of toronto water loss study & pressure management pilot
The City of Toronto water distribution system is comprised of over 5,500 km of watermain and services over 464,000 connections.
