Water from its source to our customers

Have you ever wondered how your water manages to get to you? How is a water service run? From the springs to distribution, from the Water houses  to the fountains of Rome, from leak detection to continual quality monitoring, right up to sewage treatment and the recovery of our resources: Acea manages the entire range of operations for its integrated water service throughout the supply chain.

Taking water from its source

The springs, from which we take the water that comes out of the tap in your home, are located in unpolluted areas: this is why Acea takes care of the natural environment where it operates. We are committed to respect the environment with a practical, strategic plan to encourage responsible, efficient use of our resources, to protect the sources and safeguard the natural areas where we manage our plants and service networks. Therefore, we monitor the springs using targeted, satellite surveillance to intervene only where necessary.

Numerous areas are under total protection, such as the Capore springs (997,848 m²) and the Peschiera springs (375,322 m²).

This means we can guarantee the quality and integrity of our water resource from its origins. Nowadays, Rome is one of the few metropolises in the world, which can boast a water resource, most of which does not require preliminary treatment to convert it into drinking water, thanks to the excellent quality from the very beginning. Acea manages resource captation. What does "captation" mean? This is the phase, in which water is taken from the springs and aquifers in the area, and is a crucial part of the supply chain.  Intervention plans cover not only work to optimise, detect and repair any leaks, but also to put unused sources to work and especially to strengthen and safeguard the current springs, as in the case of the works to double the Peschiera network.

Distributing the water

Once we have taken the water, we move on to distributing it via an extensive network of aqueducts and ducts. It's incredible to think that the procurement system for the entire province of Rome operates mainly with seven large aqueducts carrying water from 14 springs and numerous minor, local sources to distribution networks with a total flow of over 21,000 litres/second. There are seven main sources for Southern Lazio and the area of Frosinone, whereas 170 km of aqueducts serve the province of Benevento.
The majority of the aqueduct network is operated by a remote control system, which provides us with useful information on the state of the network to plan maintenance and extension work.

Our future, strategic objectives in our 2019-2022 business plan cover various operations to protect our water resource and improve the service quality and efficiency we offer. This will include the installation of smart water meters, including, the reduction of network leaks, the rationalisation of the treatment plants and the division of the network into districts. Other fundamental points are concerned with improving indicators of technical quality and ensuring safe water procurement.

Over 359,000 analyses carried out in the province of Rome in 2018.

Acea Elabori: quality, technology and innovation

Acea Elabori is the company in the Acea Group, which provides engineering, laboratoryresearch and innovation services to support our water and environmental activities.

Among the work carried out for the water sector, Acea Elabori is in charge of water leak detection and the division into districts  of water networks. It uses traditional, investigative and the most innovative techniques, such as remote control. It is in charge not only of data acquisition and processing for surveys, mappings and the reconstruction of stretches of network, but also of site safety activities with over 11,000 inspections each year (+27% as compared to 2017).

The company also follows innovative projects, developed by applying advanced, digital and modelling technologies for automation logic and process optimisation. 
The work of the laboratory deserves a special mention. Equipped with avant-garde equipment and a mobile centre for environmental monitoring, which make it one of the structures of excellence in the sector, the Acea Elabori analytical laboratory carries out analyses on drinking water on a daily basis to check the quality of the water Acea supplies to its customers.

Taking care of water

As part of our integrated water service, we also try to restrict network leaks.  Our operational teams working on this type of job consist of a mixed team of operators working on site, who are in constant contact with a remote-controlled monitoring team. To make water resource distribution more efficient, it is important for Acea to use its own teams equipped with special remote-controlled pressure gauges and other instruments to monitor the details of the neighbourhoods in the different water districts.

Acea has always focused on encouraging a culture of water by raising awareness among the younger generations and involving operators, associations and experts in this innovative, environmental sector. The key word to an innovative approach to the water cycle is resilience. This is a process, which connects citizens, associations, and institutions so they become increasingly aware each day of our need to focus on our water heritage, not just for us all today, but also for future generations.

Sewage treatment

This is the final phase in the Integrated Water System: the sewage network and treatment system. After being used for various civil purposes, the water is collected via the sewage pipes and sent to the treatment plants to be transformed from "waste" to a new resource for other uses, such as agriculture.

Acea manages this and many other activities according to a circular economy, which is yet another example of our commitment to protect and give value to our water resource at every stage in the supply chain.

Approximately 859 million cubic metres of water treated by the Group in 2018.
