As of today, Tuesday, April 1, 2024, drinking water has been restored across the entire Lavizzara valley, including the areas served by the Peccia Plain and the Monti di Rima. The restrictions imposed in early March 2024 have been lifted thanks to urgent interventions carried out by Azienda Multiservizi Ticinese (AMT), which manages the local water network.

The precautionary measures were introduced after chemical parameters detected in some sections of the network failed to meet Swiss health standards. In particular, aluminum levels in the pipelines originating from the Peccia Plain and the Monti di Rima exceeded the permitted limits. According to AMT, the contamination was caused by internal corrosion of the pipes, a problem exacerbated by recent adverse weather conditions that accelerated the deterioration of the materials.

Authorities' response

AMT's interventions were coordinated with the Canton of Ticino's Department of Territory and the Federal Office of Public Health (FOPH), which oversaw the remediation efforts. In an official statement, the Municipality of Lavizzara declared: «The situation is now under control. We have flushed the pipelines, replaced the most critical sections, and conducted thorough chemical analyses to ensure compliance with legal requirements». The checks were carried out in accordance with the Foodstuffs Ordinance (FSO) and the Federal Act on Water Supply (WAAct).

Impact on families and cross-border workers

The restrictions had forced many residents and cross-border workers to rely on bottled water for drinking, with estimated additional costs ranging between 50 and 100 Swiss francs per household per month. The affected municipalities — including Cevio, Maggia, and Avegno-Gordevio — set up free drinking water distribution points to mitigate the inconvenience. Cross-border workers living in these areas and commuting to Lombardy had to adjust their routines, particularly for meal preparation and personal hygiene.

Next steps: ongoing monitoring

AMT has announced an intensive monitoring plan for the next three months, with weekly checks on the water's chemical and bacteriological parameters. «We will ensure aluminum levels remain within tolerance limits for at least 90 consecutive days», a company spokesperson stated. Only after this period will it be possible to consider the reopening of the pipelines as permanent.

Comparison with the previous situation

Before the restrictions, the Lavizzara valley sourced its water from three main springs: the Peccia Plain, the Monti di Rima, and the Sambuco basin. The pipelines from the first two sources were built between 1978 and 1985 and, according to experts, had shown signs of wear for over 20 years. Internal corrosion had been underestimated until routine checks detected the first exceedances of aluminum limits, a metal that, in high concentrations, can cause gastrointestinal issues and kidney problems.

Public reactions

While many residents welcomed the restoration of the water supply with relief, concerns remain. «We had to throw away tons of food prepared with tap water», said a resident of Cevio. «Now we have to wait and see if the quality remains stable. We hope AMT has truly addressed the root of the problem». Restaurant owners and hospitality operators also had to replace equipment and tableware, incurring significant additional costs.

Operational details

What changes for cross-border workers: procedures and adjustments

Cross-border workers living in Lavizzara and working in Lombardy now face an unprecedented situation. After weeks of uncertainty, drinking water is available again, but caution is still required. Here’s what you need to know:

1. Drinking water: yes, but with care

Even though restrictions have been lifted, AMT recommends boiling water for the first 48 hours after the reopening, especially for food use. «This is a standard precaution after pipework interventions», explains the company. «There are no immediate risks, but it’s better to be safe». For cross-border workers, this means adjusting habits during the first working days in Lombardy, where many still prefer tap water for convenience.

2. Additional costs: a temporary balance sheet

Before the restrictions, the average monthly spending on bottled water for a family of four was around 30-40 francs. With the need to purchase additional bottles for drinking and cooking, costs have risen to 100-120 francs, according to estimates from some stores in Cevio. Now that tap water is safe again, families can reduce spending, but it won’t return to pre-crisis levels: «We’ll still need to buy water to make coffee and prepare baby food for a few weeks», says a mother from Avegno.

3. Impact on commercial activities

Restaurants and hotels in the area had to replace filtration systems and tableware, with average costs between 2,000 and 5,000 francs. Now that the water is drinkable again, many are considering whether to keep the new systems or revert to traditional solutions. «We installed reverse osmosis filters to ensure customer safety», explains the owner of a restaurant in Maggia. «Now we have to decide whether to keep them or not. Maintenance costs are high, but we can’t risk another emergency».

3. Comparison with other Ticino valleys

Lavizzara’s situation is not unique. In other parts of Ticino, such as Vallemaggia and Verzascata, the water network has undergone interventions due to corrosion issues. However, in Lavizzara, the problem was more severe because it involved two main water sources (Piano di Peccia and Monti di Rima) and a population spread across a vast, mountainous territory. «The valley’s topography makes continuous monitoring more complex», says a hydraulic engineer from the Department of Territory.

4. Future prospects: digitalization and maintenance

AMT has announced a plan to digitalize the water network to prevent future incidents. «We are evaluating the installation of IoT sensors to monitor water quality in real time», says the company’s CEO. «This would allow us to intervene promptly in case of anomalies». For cross-border workers, this means a more stable future, but also the need to adapt to new control procedures.

What should cross-border workers do now?

1. Check water quality: Even though AMT has lifted restrictions, it’s advisable to check monthly bulletins or visit the Lavizzara Municipality website for updates. 2. Adjust habits: If cooking in Lombardy, it’s still useful to bring bottled water from home for the first few days, especially for preparing meals for children or elderly people. 3. Monitor costs: With the end of restrictions, families can reduce spending on bottled water, but it’s wise to keep track of consumption to avoid surprises.

📊 Cost comparison before and after the crisis

• Pre-crisis: 30-40 CHF/month (family of 4)
• During crisis: 100-120 CHF/month
• Post-crisis: Gradual reduction, but not to pre-crisis levels

💡 Key takeaway While the water emergency is over, residual precautions and adjustments remain necessary for cross-border workers and local businesses.

⚠️ Important reminder Always verify updates from AMT or local authorities before making long-term changes to your water consumption habits.
