Firms are spread across Valencia, Mislata, Burjassot and Manises, among other towns. Closest to Valencia city are AQUAfuentes, AquaDux and Depósito de agua potable de Xirivella. If you’re inland, ask each firm whether your village is inside their normal working area before you book a visit.
AquaDux, AQUAfuentes and Aguas la Serreta lead on Google among firms with at least 20 reviews. The average rating across the list is 3.8 (firms with at least five reviews). A handful of five-star reviews is a start, but ask for a job you can go and see.
Tanks for drinking water should be food-grade. Ask about the base it needs, access for the delivery lorry, and what filtration the firm recommends after a water test rather than before one.
Questions to ask before you sign
- What size do you recommend for my use, and why?
- Is the tank food-grade for drinking water?
- What base and access does it need?
- What filtration do you recommend after a water test?
