Hydraulic Efficiency

Controlling leaks

AYESA has extensive experience in the optimisation of the efficiency of supply networks, not only focusing on the reduction of physical loss but also aimed at improving the overall management of the network. this product is aimed at drinking water supply network management and operating companies.

With the increasing degree of development of society today, the conservation of available water resources, i.e. the efficient use of water, is becoming more and more of a priority. Efficient use of water is understood, in general, as meaning “any activity aimed at maintaining the level of service and resources at the point of consumption for consumers, whilst enabling a reduction in the amount of water used and thus taken from the environment”. in other words, this involves optimising the overall efficiency of the system, which is the relationship between the water produced and that consumed.

Pursuing the fundamental goal of optimising overall efficiency, AYESA offers its services to operating organisations in order to implement an active network management system, based on the segmentation of this network, which allows each hydraulic sector to be known and controlled. in other words, knowing and controlling their characteristic parameters (flow rates, pressure and consumption), creating the capacity for proactivity in the face of incidences occurring on the network and providing the tools and procedures to allow the efficiency of these networks and the quality of the service provided to be maintained and improved.

It is important to mention that the development of the tools and procedures for the solution offered by ayesa is based on knowledge of the network acquired in the field. “Hands-on” knowledge of the daily operations of the network is indispensable in order to put solutions forward. Each network, each urban area supplied and each operator is unique and therefore requires specific actions and methodologies. In fact, there are no standard solutions.

In order to achieve efficient active control, ayesa provides the operating organisation with a high-calibre team with extensive experience in the various areas of knowledge necessary for this purpose. These are namely the inventory and digitalization of networks, consumer patterns, gis implementation and gis-commercial system link. Modelling and calibration, design and implementation of segmentation (including control instrumentation), implementation of methodology for permanent active control of the network, planning of efficiency improvement proposals, installation of centralised remote meter reading systems, meter error audits, creation of specific processes, etc.


  • Controlling the overall efficiency of the system: up-to-date knowledge of the hydraulic and physical status of the network itself (gis); continuous control of the hydraulic status of the network (segmentation/active control); optimisation of service conditions (pressure, flow rate, leaks, etc.), updating campaigns for the meter depot and reading routes according to hydraulic sectors; reduction of the times for the detection and resolution of incidents on the network; prioritisation of network improvement work; knowledge of consumer and billing profiles and of the status of the meter depot.


  • Inventory and digitalization of networks: the goal is to know the situation and function of each element on the network through inventory and digitalization in a geographic information system to obtain a single piece of data (geospatial and alphanumeric) in order to facilitate the operating, maintenance and management of the network.
  • Registry of users: the goal is to know the situation in each of the drinking water service connection points, know which contracts are linked to them and conduct surveys on the status of all meters and measuring facilities. these are subsequently digitalised in gis and linked to the commercial billing system.
  • GIS: the development and implementation of a geographical information system that allows us to give the operator access to georeferencing information in relation to the network and its users and develop all applications that may be useful or necessary for the management of such.
  • Modelling and calibration: based on the digital information available in relation to the network and the information in relation to demand, flow rate and pressure, the aim is to show the reality of the network as reliably as possible for: segmentation design, prediction of behaviour in the event of incidents and/or supply cut offs, the design of new systems and extensions and the restoration of existing systems, capital investment decisions, etc.
  • General and final segmentation design plans: to facilitate the active control of the network, this is divided into smaller hydraulic units. Based on the digital network information, information in relation to demand and information obtained in the field, the design of the hydraulic sectors, necessary works and instrumentation to be installed is carried out.
  • Implementation of segmentation/active control: execution of the planned works and implementation of the hydraulic sectors designed and the control instrumentation for such (leak testing and configuration of equipment), development of operating procedures and maintenance of sectors.
  • Recovery of flow rates/hydraulic audits: determining any physical leaks in each sealed hydraulic sector, carrying out repairs and performing an assessment of the hydraulic units to determine the different anc. components.
  • Diagnostic/proposal for improvements: based on all the information obtained from the sectors, a diagnostic report of the situation of the distribution network is generated and specific improvement proposals are drawn up.
