Sentry meters, to detect water leaks in the network

The pilot project involving the installation of Kamstrup meters was carried out in Conselice, near Ravenna, and yielded excellent results. The tests now continue in Modena, covering a larger area

The Flow IQ® 2200 manufactured by Kamstrup, a well-established European supplier, is a sentry meter that can “listen” to the network thanks to a built-in hydrophone, i.e. a sensor designed to capture sounds and other acoustic signals underwater, which in this case is able to detect the noise associated with any water leaks.

By placing the meters at strategic points in the network, about 50 metres apart, it is possible to create a grid within which continuous monitoring can be carried out.

The meters transmit to a digital platform (called the LeakDetector) the minimum value of noise detected in 24 hours: if this is high, the meters will be highlighted with different alarm levels and analysis of the data will make it possible to identify whether it is indeed a water leak.
If a leak or break code is activated for a meter, the customer will be notified promptly by our technicians.

The meter testing phase started in May 2022 with the installation of more than 900 meters in the municipality of Conselice, where continuous monitoring of the water network began in September 2022 with real-time analysis of the leaks present, thereby allowing targeted intervention for repairs.
It is planned to continue testing over a wider area, starting with Modena, where 1,300 meters are being installed.

 

The Conselice pilot project: benefits noted


Reliability

The meters are extremely reliable, the leak and break indications that were verified were correct and no false positives were found.

Promptness

We intervened before customers called us: many leaks were repaired the day after they appeared, whereas previously some leaks would only have been detected following issue of a bill with an unusually high consumption figure.

Permanent monitoring

Compared to the installation of standard meters, the main difference is that with Flow IQ® 2200s, a permanent water leak monitoring system is put in place. Kamstrup meters are also smart meters and automatically send data to the portal.

Rapid localisation

If the meters are correctly positioned, field localisation is quick because the area to be investigated is confined.

Integration

The system interfaces seamlessly with other company monitoring tools.

Affordability

By correctly establishing the number of meters required, good network coverage is achieved without an unsustainable increase in costs.

Food for the soul

Food for the soul gobbi_claudia_thumbnail.png Claudia Gobbi is a service manager in the Facility Management department, dealing with the management of spaces/premises within the Group. Like many other staff members of the Hera Group, she continued working throughout the entire lockdown. Working in the company for over thirty years, Clauda has never witnessed such a critical moment as the pandemic period, but like many other Hera employees she continued to work throughout the entire lockdown. “We immediately realised how serious the situation was. It was necessary to take action quickly to protect colleagues, following all regulations laid down by the Safety Committee. “The whole year was incredible, the first three months in particular, but the results achieved gave us some serenity and the monitoring carried out by the authorities confirmed we were following correct procedures. We felt really useful to our company and colleagues. Just as an example, the fact of keeping the company canteens open throughout the lockdown was very important for our colleagues, at a time when nowhere was open outside our premises.” As a lover of travel, music and art, Claudia suffered under the Covid restrictions which stopped her enjoying her hobbies. “Using travel to open my mind to other cultures and realities different from my own is always a very moving experience for me.” She says that what she misses most is “Food for the soul”: museums, cinema, and theatre. “It’s not enough to eat food for the body; culture is an essential part of my life. As an architect, going to exhibitions and museums served as a stimulus to open my mind and inspire new ideas and thinking also in my work.” no

From Padua to Udine: a valuable teamwork experience

From Padua to Udine: a valuable teamwork experience borgato_marco_thumbnail.png 2020 was a year focused on the need for resilience and skilfully-managed changes. This was put into practice by 13 colleagues of AcegasApsAmga who offered their own skills during the summer to colleagues in one of the Group’s companies, ASE, which found itself dealing with an unexpected increase in workload due to the Covid health crisis. This willing team included Marco Borgato, who transferred to Udine for two weeks to take part. Marco, what do you do in AcegasApsAmga? For about 4 years now, I’ve been working in the Water Department in Padua, where I deal with the electrical side of water systems like pumps, transformers, cathodic protection. Often, people have no idea how much electricity is involved in the water system. A multifaceted skill set, then: with the Covid crisis, were you asked to collaborate with ASE? With the end of lockdown, ASE experienced an unexpected increase in workload in a very short space of time, such as the maintenance of electrical systems in schools which needed to be ready quickly for the high school leaving exams. So I was asked to join a team of colleagues in Udine for a few weeks. What did you do during your time in ASE? ASE manages electrical systems in many public buildings in Udine. So, I was able to put my electro-technical skills into practice in various types of systems, such as checking the circuit breakers in a school. Would you recommend this experience to your colleagues if the need were to arise again? Absolutely, yes! It allowed me to meet colleagues from other locations that I would not have met otherwise. There was an instant positive work atmosphere and we became a close team really quickly, all of us trusting each other. no

A source of clean energy from sewers and wet waste: Biomethane

An investment of Euro 37 million. A plant that disposes of 100 thousand tonnes of organic waste produced by separate waste collection and another 35 thousand tonnes coming from green waste and pruning material.

Biodiesel has been developed also from used food oil

Fuel may also be extracted from vegetable oils. Used domestic vegetable oil (such as frying oil) which is recovered by multiutility services via roadside containers and drop-off points, is transformed into biodiesel, which in turn is used to fuel the vehicles used for urban waste collection.

Dialogue with the urban context for new energy: the Borgo Panigale cogeneration plant

District heating is already in itself a "sustainable" and environment-friendly solution, because it can guarantee better performance than traditional domestic boilers. In addition, the plant located in Borgo Panigale ensures lower emissions into the environment, more reliability and greater availability of energy. The system can heat the equivalent of 8,000 residential units. Currently, the turbines can produce 35,000 MWh of energy per year, almost twice as much as in the past.
