Sewage treatment plants in Binissalem, among vineyards and public supply wells
Binissalem is a wine village with many country houses on rural land, off the mains. Underneath are two aquifers the Water Plan watches closely: one because of nitrates and the other because it also supplies Palma. We are Joaquín and Juan, installers in Mallorca since 1998: we supply the new treatment plant, install it, do the electrics and prepare and sign the documents for your architect or engineer to file.

What happens under Binissalem
Two entries in Annex 9 of the Balearic Water Plan concern Binissalem.
Penyaflor: water for Palma too
The Penyaflor groundwater body (1809M2), shared with Alaró and Consell, helps supply Palma as well as Binissalem, Alaró, Consell and Lloseta, and is abstracted at 103 %. It is Jurassic limestone and dolomite with Oligocene conglomerates. Where there are public supply wells there are protection perimeters that change the unit (art. 70.10, table 13).
Inca: nitrates
Part of the municipality lies over the Inca body (1811M3), in poor status because of nitrates (66 mg/l) and under vulnerable-zone programmes since 2010. Among others it receives the water from the Binissalem treatment works (0.35 hm³ a year), which the Plan lists as already extended and improved. A house that treats its water well and irrigates its plot helps in the right direction.
Country houses, separate waters
In a country house the treated water goes to the green area on the plot itself: 25 m² per population equivalent (art. 70.12). And roof water goes its own way, because the treatment plant may not collect rainwater (art. 70.7.d).

The rules here
What the rules require of the unit, and how it is maintained
The unit must be approved, CE-marked and compliant with the EN 12566 family (art. 70.14), and its manufacturer must certify a minimum performance of BOD₅ 70 %, COD 75 % and suspended solids 70 % (art. 70.10). We work with all brands; as an example, the GRAF one2clean.
Maintenance: the services required by the rules or, if the manufacturer asks for more, the manufacturer's (on the GRAF one2clean, twice a year), with a signed report; and emptying the sludge, by an authorised waste company, as the law requires (art. 70.7.f).
What we do
What we do in Binissalem, and what others do
- A new treatment plant for the country house, approved with CE marking and EN 12566, chosen by bed spaces, by whether the house is seasonal and by what the Inca nitrate-vulnerable zone requires. We work with all brands; for example, the GRAF one2clean.
- Documents even for a two-bed house: the responsible declaration is always filed (art. 70.4). As the installation company we prepare and sign the data sheets, the performance and the maintenance plan; your architect or engineer files them.
- Installation and electrics among the vineyards, with roof water kept separate, plus commissioning, as a licensed low-voltage installation company. We don't subcontract anyone.
- The pit, through limestone and conglomerate if the house sits over Penyaflor: your builder digs it, following what we give them in writing according to the manufacturer; emptying the sludge, an authorised waste company (art. 70.7.f).
- The services: those required by the rules or, if the manufacturer asks for more, the manufacturer's (on the GRAF one2clean, twice a year), with a signed report, so the water reaching your green area leaves properly treated.
How we work
How we do it in Binissalem, in 3 steps
1
Location and nearby wells
With the address we check on the DGRH map whether the house is inside the perimeter of a Penyaflor well, which supplies Binissalem and part of Palma.
2
Green area and quote
We work out the 25 m² per population equivalent the treated water must irrigate and send you in writing the unit, the electrics and the pit for your builder.
3
Installation, start-up and documents
We install once the pit is ready, start the plant and hand over the signed documents; your engineer files the responsible declaration with the DGRH.

Common questions
Frequently asked questions about treatment plants in Binissalem
Could my house in Binissalem be inside a public supply well perimeter?
It could. The Penyaflor aquifer, which Binissalem shares with Alaró and Consell, supplies these villages, Lloseta and partly Palma, according to Annex 9 of the Balearic Water Plan (Royal Decree 49/2023). The protection perimeters are shown on the DGRH map: we check them with the location before quoting, because inside the maximum restriction perimeter the unit changes.
What does it mean that Binissalem lies over a nitrate-vulnerable zone?
The Inca body, under part of the municipality, has 66 mg/l of nitrates and vulnerable-zone programmes since 2010, according to the Water Plan. For your treatment plant it means the treated water goes to a green area on the plot and, if the plot lies in a high-vulnerability zone of the aquifer, the Plan also lists denitrification and disinfection, which table 13 marks as recommended up to 12 population equivalents and table 14 requires above 12 (art. 70.10).
I have a country house with 8 bed spaces. How much green area do I need?
At least 200 m²: the Water Plan requires 25 m² of green area per population equivalent (art. 70.12 of the Balearic Water Plan, Royal Decree 49/2023), and in a home the guideline equivalence is one per bed space (art. 70.8, table 12). Without that land, the options are a drainage trench, with a favourable report and prior authorisation, or a sealed holding tank emptied periodically.
Which treatment plant do you install?
A new extended-aeration treatment plant, approved, CE-marked and compliant with EN 12566 (art. 70.14 of the Water Plan). We work with all brands; as an example, the GRAF one2clean. The model is chosen by the bed spaces, by whether it is a holiday home and by what the area requires.
When you finish, which documents do you give me?
As the installation company we prepare and sign what your architect or engineer asks for: the declaration that the installation complies with the rules, the manufacturer's data sheets and performance, the maintenance plan and the electrical installation certificate. With that your architect or engineer files the responsible declaration with the DGRH (art. 70.4 of the Balearic Water Plan, Royal Decree 49/2023).
The house is small, with 2 or 3 bed spaces. Does it still have to be declared?
Yes. The responsible declaration to the Directorate-General for Water Resources is always filed, also below 12 population equivalents (art. 70.4 of the Balearic Water Plan, Royal Decree 49/2023). What only exists above 12 is the yearly report of the performance checks and the sludge log (art. 70.11).
