ALREADY WITH DATAWATER IN PORTUGAL
Tap water, municipality by municipality.
Ayus installs and maintains 4-stage water filters at home, hidden under the kitchen sink. Before we suggest a filter, we want to know what water reaches your home. So we gather, municipality by municipality, what each water utility publishes.

Every municipality drinks a different water.
Where it comes from, who treats it and what it contains. Choose your district and then your municipality, on the map or in the list. The values are the ones each water utility publishes; during the visit, we test the water in your kitchen.
