ComoAqua > WATER QUALITY

Good, safe and controlled water

Drinking water is a precious resource that must be protected

From the source
to the home tap

Water at the source reflects the natural composition of the surrounding terrain, inevitably influenced by natural change processes and human anthropogenic action – urbanization, agriculture, and industry.

The Manager's goal is to provide the User's faucet with potable water for every need: drinking water, cooking water, washing water.

The necessary requirements for identifying potable water have been defined by the WHO - World Health Organization -, elaborated at a community level with EU Directive 2020/2184, and incorporated by the competent supervisory bodies for each country; in Italy by the Ministry of Health with Legislative Decree 18/2023.

THE LABORATORIES.

As Acqua, to guarantee the quality standards of the Integrated Water Cycle, it utilizes an internal analysis laboratory, which constantly monitors the operation of the treatment plants for both drinking water and wastewater.

The Multi-site Laboratory – consisting of a Drinking Water laboratory and a Wastewater laboratory – is accredited, according to UNI CEI EN ISO/IEC 17025:2018 standard, by ACCREDIA.

ACCREDIA is the sole national body competent to grant or revoke accreditation at the national level for testing laboratories. ACCREDIA grants accreditation to a laboratory when it has ascertained its technical and management competence in accordance with the requirements of the standard.

Accreditation is the formal recognition of the laboratory's suitability to determine the characteristics of a product and/or material based on specific procedures.

The accreditation certificate of the Multisite Laboratory of Como Acqua and the list of accredited tests can be consulted at the following links:

In order to pursue the daily goal of distributing potable water for human consumption, the Operator monitors the water along its path, from collection (spring, well, or surface water intake), through the supply lines, to the storage points: tanks, where treatment plants are located (disinfection with sodium hypochlorite, UV rays, ozone, sand and carbon filters, etc.), and then continues through the distribution network (aqueduct system) to the meter, the point of delivery of the water to the user, at which point all the Operator's responsibilities end.

Monitoring is carried out remotely using telecontrol and in the field through site inspections, ordinary and extraordinary maintenance, and by controlling water quality according to analysis plans, the results of which are reported in a table. The average value recorded refers to the results of analyses carried out in the year 2025.

The management of water service

As Acqua is the Integrated Water Service Manager in the province of Como and is responsible for managing at least one of the services of aqueduct, sewerage, and purification for 146 municipalities in the Como area, ensuring water supply to approximately 200,000 domestic and non-domestic civil users.

The drinking water cycle begins with abstraction from sources – which are distinguished as wells, springs, or lake intakes – continues with collection, and conveyance to storage points, such as reservoirs, up to distribution. Como Acqua's aqueduct network extends for approximately 5,125 km, a figure constantly updated thanks to mapping and census activities of existing structures.

The sources of supply

Water supply in the Como area is guaranteed by 314 wells and 518 springs or surface diversions. The province, divided between mountainous areas and hilly or flat zones, sees a prevalence of springs near Lake Como and wells in the flat areas, primarily fed by potable or treatable groundwater. With the increasing demand for water and the challenges posed by climate change, Como Acqua is committed to researching and activating new withdrawal sources through wells and diversions.

Treatment and disinfection infrastructure

Como Acqua's 128 treatment plants and 489 tanks ensure high operational standards and consistently elevated water quality. Below are some descriptions of treatment plants used by the Operator (taken from the “Guidelines on treatment devices for water intended for human consumption pursuant to Legislative Decree of February 7, 2012, no. 25”).

  • Mechanical Filters: Remove undissolved substances from water using materials like sand, quartzite, or pyrolusite. These filters are inspectable and washable to ensure efficiency and prevent clogging.
  • Activated Carbon: Used to remove organic and inorganic pollutants, they improve the color, odor, and taste of water. Activated carbons are obtained from lignite, peat, coconut shells, or other plant and mineral matrices, with a high adsorptive surface area (500 – 1,500 m²/g).
  • Chemical Disinfectants: Chemical disinfection, primarily based on chlorine and ozone, eliminates pathogenic microorganisms and prevents recontamination of water during distribution.
  • UV Systems: They use UV radiation (240-280 nm) for germicidal action. These systems keep the organoleptic characteristics of the water unchanged.

How Acqua ensures efficient and sustainable management of drinking water, addressing the challenges of increased demand and climate change. Thanks to an extensive network of sources and treatment plants, it guarantees the supply of quality water to the province of Como.

#
The quality of water

How Acqua punctually and regularly carries out checks regarding water quality according to current regulations, with the awareness that the health and safety of its users represent an absolute priority.

  • The monitored parameters include chemical, physical, and microbiological ones, as established by Annex I of EU Directive 2184/2020, as transposed into Italian law by Legislative Decree 18/2023.
  • How Acqua analyzes the organoleptic characteristics of the water collected, inevitably conditioned by the territory's composition, natural changes, and human activity, to make it potable and safe for human consumption.

The monitoring of the quality of water collected and distributed takes place at the internal drinking water laboratory, accredited according to the UNI CEI EN ISO/IEC 17025:2018 standard for chemical and microbiological tests, in 2020. Throughout 2023, Como Acqua conducted periodic analyses that confirmed compliance with legal limits, ensuring that the distributed water was safe and potable.

The parameters checked

To view the updated and precise data regarding the analyses, please refer to the table above.

The quality of the water supplied to the network is constantly monitored by the Operator through a monitoring plan shared with the ATS. In the event of confirmed exceedances of the parameter values established by law by the ATS or through its own monitoring plan, the Operator activates all the most suitable actions to ensure a return within the prescribed limits: checks on the correct functioning of the systems, corrective technical interventions, and qualitative re-checks.

Water saving

It is of paramount importance to remember that water is a precious and finite resource, “threatened” by climate change and often unsustainable use. Therefore, it is everyone's duty to consume it responsibly, avoiding waste. Como Acqua promotes 10 simple practical tips that can be a starting point for protecting this resource.

#
1. Check for leaks and implants
Periodically check the plumbing system and repair any leaks. A dripping faucet can waste up to 5 liters per day: a small intervention can prevent significant waste over time.
#
2. Faucet closed, water saved
Turn off the water while brushing your teeth or washing your hands. With the tap open, up to 30 liters are wasted. 1.5 liters are enough for your teeth and 6 for your hands. A simple gesture, but very effective.
#
Water has a second life
Reuse the water from cooking pasta or washing fruits and vegetables to rinse dishes or water plants (if it's not salted). It's an easy action that reduces household waste.
#
4. Always fully loaded
Use the washing machine and dishwasher only when they are fully loaded. Reduce washes, consume less water, and save energy. A good habit that is good for both the environment and your wallet.
#
5. Technology that's good for you
Install sensor faucets or faucet aerators. They limit flow without reducing washing effectiveness. A small technological innovation, with great results.
#
6. Two keys, double savings
Prefer dual-button flushers: they allow you to choose the flow you need and save up to 100 liters per day. An automatic gesture that is worth a lot.
#
7. Choose the shower, not the bathtub
A short shower uses much less water than a bath. You can save up to 1,200 liters per year. The same effectiveness, less impact on the environment.
#
8. In absence, turn off the water
If you leave your home for several days, turn off the central heating system. This will prevent waste from potential leaks and protect your home from unforeseen damage.
#
9. Irrigate intelligently
Use drip, timed, or subsurface irrigation systems. They consume less and are more effective. Irrigate in the morning or evening to avoid evaporation.
#
10. Breathing surfaces
Choose draining pavements for outdoor areas. They promote natural drainage, recharge water tables and reduce urban overheating.

To avoid waste and adopt virtuous behaviors, it's also important to be aware of consumption: both personal, by understanding the water footprint of daily actions and objects; and at a population level.

Pursuant to ARERA resolution no. 609 of 2021, article 2 “Amendments and integrations to Annex A of resolution 586/2012/R/IDR” paragraph 3, the average annual consumption of end users detected in the managed territory, broken down by user type, is reported.

Un indicatore chiave dell’efficienza delle reti acquedottistiche è il volume di acqua dispersa, calcolato come la differenza tra l’acqua immessa nel sistema (attraverso i pozzi di captazione e i punti di scambio) e quella consumata dagli utenti. Questo indicatore è costantemente monitorato dal gestore, poiché è un parametro che l’Autorità di Regolazione per Energia Reti e Ambiente utilizza annualmente per verificare il corretto funzionamento della rete acquedottistica. Per il biennio 2024-2025 l’indicatore di riferimento M1 dovrà raggiungere i seguenti livelli rispetto all’indice rilevato nel 2023 pari al 19,02%: – 2024: 18,07% – 2025: 17,16%.

The ownership structure of water supply by the water provider

As Acqua is a publicly owned company, managed by the municipalities of the Province of Como, it ensures transparent and responsible control of water resources. The supply sources (wells, springs, and diversions) are equipped with public concessions to which Como Acqua has succeeded in ownership.

The tariff system

The water tariff includes a fixed component, which covers the costs of managing and maintaining infrastructure, and a variable component, based on the actual water consumption by users. The Regulatory Authority for Energy, Networks and Environment (ARERA), as the regulator of the water service, defines the water tariff method (MTI), which establishes the rules for determining tariffs, a task delegated to Local Authorities, i.e., the Basin Government Bodies (EGA).

An aspect of fundamental importance to mention is that the rates are structured to incentivize responsible water use and support water conservation initiatives.
