Portugal's leading water treatment specialist. Official OSMOTIC RO distributor — custom-configured reverse osmosis with professional installation and annual maintenance.
Fonteval is Portugal's most established premium water treatment company, operating from Porto de Mós in Leiria with service coverage across central and northern Portugal. As the official Portuguese representative of OSMOTIC (reverse osmosis systems) and OLYMPIA (water softeners), Fonteval brings industrial-grade water treatment technology to residential clients.
Where most products on this list are boxed consumer systems you install yourself, Fonteval works differently. Their team conducts a water quality analysis for your property, then configures and professionally installs a reverse osmosis system sized to your water quality and household demand. Systems can incorporate RO, ultrafiltration, UV sterilisation, iron removal, descaling, and whole-house softening — whatever the water test results indicate.
This consultative approach has advantages: the system is matched to your actual water rather than worst-case specifications, and professional installation eliminates DIY errors. It also includes annual maintenance contracts, which means filter replacements and system checks are handled by the same team that installed it.
Fonteval is particularly relevant for properties in central and northern Portugal with older plumbing, iron-contaminated borehole water, or households that want a fully managed solution rather than a product they configure themselves. Coverage: Leiria, Porto districts, and 16 surrounding municipalities.
