Water supply network management

projeto de gestão de redes de abastecimento de água

Water scarcity and risk of water shortage are forcing companies related to water and sewage public services to continuously improve their operations. In Brazil, losses are elevated in water supply networks: according to the National System for Information on Sanitation (SNIS), they are estimated in 37%. Water supply network management and operation modernization contribute not only to minimizing losses, but also to increasing the quality of their services and lowering operational costs. Find out more about all services Sharewater offers for managing and controlling losses in networks and how they can be integrated.

Sectorisation and loss control in water supply networks

Sharewater develops sectorisation and loss control projects for networks of any size. A water network’s sectorisation consists of separating it in District Metered Areas (DMAs), which allows for the analysis, management, and maintenance of the network in a localized way, avoiding interventions that might affect the network as a whole. Each district can have its own pressure and flow measurement systems – which allow for more control on how much water is distributed and an estimation of losses due to leaks – and pressure control systems (such as pressure regulation valves, pressure reduction valves, and pressurizers) – which help avoid letting the pressure get not only too low, impairing the supply service for the population, but also too high, maximizing losses through existing leaks and accelerating the deterioration of equipment and pipes, increasing the occurrence of new leaks.

Computer hydraulic simulation

Computer hydraulic simulation is one of the most advanced technologies for operating and planning water distribution networks, allowing for a better evaluation of pressure distribution, a more accurate prediction of the impact of maintenance and intervention, as well as estimating losses from leaks, among other benefits. It also helps in planning future expansions through simulation of several scenarios of new network implementation and changes in citizen occupation profiles, as well as consumption and loss indexes.

Simulation software can also be integrated to georeferencing systems and monitoring and automation systems, which allows for a significant improvement on model precision and, therefore, on hydraulic results.

Sharewater develops hydraulic models for networks of any size, also working on their integration with existing management, georeferencing, and automation systems.

Production, storage, and water distribution systems automation and monitoring

Water production and storage systems monitoring and automation help preserve the quality of water produced, monitor its amount, control reservoir levels (avoiding losses due to overflow), and monitor the performance of several kinds of equipment in order to allow predictive maintenance, among other benefits. This guarantees high quality and lower operational costs for these systems.

For water distribution networks, monitoring and automation are great allies of sectorisation and loss control, as it makes it possible to remotely monitor the amount of water distributed, detect leaks, and monitor and control the pressure in the network.

Sharewater designs complete monitoring and automation systems using proprietary and third party technology. These projects encompass everything from existing systems inspection and diagnostics to projecting new systems – including selection and dimensioning of all necessary equipment such as sensors, actuators, and communication systems – and implementing supervisory systems (SCADA software).
