1. Importance of appropriated sectorization to reduce real water loss in public supply system. / Importância da setorização adequada para combate às perdas reais de água de abastecimento público.
The following study aims to present the effect of pressure reducing in the distribution networks over the water real loss. For development of the studies, were collected field data that allowed to evaluate the distribution systems conditions and build mathematical models for hydraulic simulations. From the hydraulics models, were developed cases for the Wate

2. Water losses in public water network supply : diagnostic, control and reduction method by the geographic information system / Perdas fisicas de agua em sistemas de abastecimento : metodo de diagnostico, controle e redução atraves de sistema de informações geograficas
Nowadays, the water for human consumption has been adding social and economic considerable values, due to its strategic relationship between the increasing demand in detriment to the offer, tending to scarcity, mainly in the big centers, so the occurrence of high levels of physical losses, in the water supply system (WSS), has become a great problem to be fa

3. Analysis of the optimal location of pressure reducing valves in water distribution systems considering multiple objectives / Estudo ótimo da localização de válvulas redutoras de pressão em sistemas de distribuição de água considerando objetivos múltiplos
In Brazil, water distribution systems with high leakage levels represent a problem with multiple implications for water utilities. Leakage, which accounts for the dominant component of water losses, produces negative effects from the economical, as well as from the operational perspectives: increase in pumping energy, compromise of water quality, increase in

4. Modelagem multicritÃrio em grupo para planejamento estratÃgico do controle de perdas no abastecimento de Ãgua / MulticritÃrio modeling in Group for Strategical planning of the Control of Losses in the Water supply
The strategic planning to control losses in water supply systems involves the participation of several organizations in the decision making about the actions to be developed, specially after the increasing awareness with issues related to water. These organizations have different objectives, responsibilities and interests, becoming necessary a structured pro

5. Applying computational model to water loss management in supplying systems / Aplicação de modelo matematico de simulação-otimização na gestão de perda de agua em sistemas de abastecimento
This work presents, under diverse aspects, the water losses that occur in the distribution networks of the water supply systems and the available mechanisms of control. Amongst the objectives, it detaches the proposal of a computational model as a new tool for leak localization. The considered model was developed through the coupling of hydraulic simulator b

6. Calibração de modelos de redes de distribuição de água para abastecimento considerando vazamentos e demandas dirigidas pela pressão / Water distribution network calibration model considering leakage and head-driven demands
Brazils water distribution systems usually present a high percentage of so-called physical losses, of which a significant portion is caused by leakage. Therefore, it is of fundamental importance, not only from the financial standpoint in terms of the pumped and chemically treated water but also particularly from that of the preservation of this natur
