Innovation and pressure management for the efficiency of the water network - MiDoMet

The management of water losses is an essential tool for optimizing the functioning of the aqueduct network. The procedures used in this area are based:

On the active control of leaks, on pressure management, given the relationship between pressure and flow rate of the network, on the speed of repair interventions and on scheduled maintenance plans .

Smart systems for measuring flow rates and pressures offer considerable support for the management of the aforementioned elements and facilitate the creation of water districts, as they allow information on the status of a node or network to be obtained and to intervene quickly if necessary.

Despite their usefulness, however, the diffusion of such systems is hindered by the high cost and complexity of the installation and maintenance required. In aqueduct districts with reduced user density and limited extension, the use of remote monitoring systems is more effective as long as they are economically sustainable, simple, self-powered and above all equipped with "intelligence" to detect a flaw and alert promptly or preventively.

An experiment in this sense was carried out by Piave Servizi S.r.l. during the years 2015 and 2016.

Smart monitoring

Piave Servizi S.r.l. is a service company that provides water supply to a population of approximately 350,000 people, with 296 km of supply, 2972 km of distribution and 431 km of connections.

With a view to improving the control and recognition of losses, as well as of the knowledge of the dynamic behavior of the network, the company, at the request of the Engineer. Roberto Celegato, Head of the Network ManagementAqueduct sector and innovative activities, has started an intelligent monitoring experiment using our technology with MiDoMet Pressure a> e MiDoMet Special characterized by long autonomy, versatility and suitable for installation in hostile environments

During an initial phase, given the need to reliably monitor the pressure in the network, the users were chosen in the area of Lanzago di Silea (TV) public areas that generate the least consumption throughout the day (e.g. cemetery areas).

Installation map

In addition to measuring pressure, specific consumption is also detected, thus providing a service to the institutions themselves. The devices, in addition to ordinary sampling (every hour) and sending (every 8 hours), immediately alert the management system and contacts if the guard thresholds are exceeded. authorized.

This approach is a good compromise between the need to have sufficiently updated data and at the same time to be promptly alerted if a problem occurs.
