Water from its source to our customers

Have you ever wondered about the overall path your water stakes to you? What processes are involved in the management of  water services? From the springs to distribution, from the Water houses  to the fountains of Rome, from leak detection to continual quality monitoring, right up to treatment and resource recovery: the range of operations followed by Acea in order to manage the integrated water service concerns the entire supply chain.

Water withdrawal from source

The springs from which we draw the water that comes out of the tap in our homes, are located in unpolluted areas: with this in mind, Acea takes care of the natural environment  in its areas of operation. Our material and strategic commitment to respect for  the environment is reflected in a responsible, efficient use of resources,  protection of  the sources and conservation of  the natural areas where we manage our plants and service networks.  We therefore  monitor the springs using targeted, satellite surveillance  intervening wherever the nees arises.

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

All this means we can guarantee the quality and integrity of our water resource from its origins. Rome today  is one of the few metropolises in the world, that can boast a water resource, which mostly  does not require treatment prior  to conversion into drinking water, thanks to its excellent quality right from the source. Acea handles resource catchment. What does "catchment" mean? This phase, during  which water is taken from the springs and aquifers in the area, is a crucial part of the supply chain. In this context intervention plans cover not only actions to optimise, detect and repair any leaks, but also to put unused sources into operation and especially to upgrade and enhance the safety of existing springs, as in the case of the works to double the Peschiera pipeline.

Distributing the water

Following withdrawal of the water,  the next step is distribution via an extensive network of aqueducts and pipelines. Just think that the procurement system for the entire province of Rome operates with seven large aqueducts carrying water to distribution networks from 14 primary supply sources and numerous smaller, local sources, with a total flow of over 21,000 litres/second. There are 80, of which 74 are active, main sources for Southern Lazio and the Frosinone area, whereas 2,060 km of aqueducts serve the province of Benevento.
Most of the aqueduct network is remotely operated, a remote control system, that provides useful information on the state of the network for the putpose of planning maintenance interventions and upgrades.

For the future, our Business Plan strategic objectives cover various operations to protect our water resource and improve the quality and efficiency of the service offered, including the installation of smart water meters,  the reduction of network leaks, the rationalisation of treatment plants and division of the network into districts. Other fundamental points concern the improvement  of technical quality indicators and the safety enhancement of water procurement.

In 2021, 448,838 analyses were carried out

Acea Elabori: quality, technology and innovation

Acea Elabori is the Acea Group, company that 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, combining  traditional, fact finding with more innovative techniques, such as remote control. It handles both the acquisition and processing of data for surveys, mappings and the reconstruction of network,  aections, and site safety activities.

The company also follows innovative projects, developed  via the application of advanced, digital and modelling technologies with a view to process automation and 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  drinking water analyses 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 endeavour to minimise network leaks.  Our operational teams working on this type of intervention consist of a mixed team with 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 neighbourhoods in the different water districts.

Acea has always been committed to encouraging a water culture by raising awareness among the younger generations and involving operators, associations and experts in this innovative, environmental sector. The key word to  innovative management of the water cycle is resilience. This is a process,  that connects citizens, associations, and institutions,  so that each day they become increasingly aware of the need to focus on protecting our water heritage, not just for everyone here and now, 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 further uses, such as agriculture.

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

1,318 million cubic metres of water were fed into the network by the Group in 2021.
