Tap water in Esplugues vs. Oasly
In Esplugues, 81% of the population gets water from Zona B, which measured 26.6 °f in January 2026. It is safe to drink and moderately hard. Here is how it compares with water from a reverse osmosis unit.
Hardness (SINAC)
Zona B (81% of the population): 26.6 °f, sample of 5 January 2026. Moderately hard on the FACSA scale (SINAC, Zona B)
Reduces the minerals that cause limescale, then remineralises with calcium, magnesium and potassium
Safe to drink?
Yes. SINAC's latest bulletin rates it fit for human consumption
Starts from that same water and filters it at the point of use
Limescale at home
Noticeable on kettles and taps, though less than with hard water
Fewer of the minerals that form limescale in the water you drink and cook with. Shower and washing machine stay the same
Taste
Mains water is disinfected, and some people notice a chlorine taste
Reduces chlorine (tested by SGS) and remineralises so it does not taste flat

Data from SINAC (Spanish Ministry of Health), read on 9 October 2026. SINAC reports by supply zone, not by neighbourhood. Hardness scale: FACSA (7–14 °f soft, 14–32 moderately hard, 32–54 hard). Hardness is not a health issue: it affects taste and limescale. More context on our page about water hardness in Barcelona. Esplugues' Zona D (19% of the population) has no hardness data in SINAC.

€27.90 every 4 weeks or €279 a year, with the unit, installation, filters and maintenance included. If you prefer to buy it, it is €699 installed (€629 for the unit only). In Barcelona city the fee is €24.90; in Esplugues it is €27.90.
Is the water hard in Esplugues?
It is moderately hard, close to hard. According to SINAC, Zona B, which supplies 81% of the population, measured 26.6 °f in the sample of 5 January 2026. On the FACSA scale, 14 to 32 °f is moderately hard; from 32 °f it is hard. For Zona D (19% of the population), SINAC has no hardness data.
What if I live in Esplugues' Zona D?
SINAC does not publish hardness for that zone, and we cannot tell from your address which zone you are in. What we do is measure your water's TDS before and after installation and show you both numbers.
How long does installation take?
In most cases 3 to 7 days from your first message. We need the cold-water feed and drain under the sink, and usually a dedicated faucet, which needs a hole in the worktop or sink; a 3-way faucet is another option. On the day, we measure your TDS before and after and show you both numbers.
Can I install it in a rented flat?
Often yes, but ask your landlord first, mainly about the hole for the faucet. If drilling is not allowed, a 3-way faucet may work instead. If that is not possible either, we are probably not the right option for you, and we would rather say so up front.
Is there a minimum term?
No. There is no minimum term. To cancel, give us two months' written notice.
Is tap water in Esplugues safe to drink?
According to SINAC, the latest bulletin for Esplugues' networks is "fit for human consumption". You do not need reverse osmosis to make the water drinkable: what changes is the taste, the limescale in your kettle, and not having to buy bottled water.
