Muro: s'Albufera, farmland and holiday lets
Three things come together in Muro that weigh on a treatment plant: a protected wetland, an aquifer declared vulnerable and houses that go from a few bed spaces to many.
s'Albufera, the largest wetland in the Balearics
S'Albufera de Mallorca has been a natural park since 1988 (Decree 4/1988), with 2,036 ha between Muro and sa Pobla, and is listed in the wetland catalogue of the Balearic Water Plan under Muro (code MAMT07). For a house of 12 population equivalents or more, being 500 m or less away means applying to the Direcció General de Recursos Hídrics for prior authorisation instead of a responsible declaration. That is why in Muro we measure the distance first.
Virtually the whole municipality, a vulnerable zone
The Balearic Decree 18/2023 (BOIB no. 39, 28 March 2023) puts 58.5 km² of Muro in the zone vulnerable to farm nitrates: virtually the whole municipality, which is about 58.6. It is the fertiliser rule, not the treatment plant rule, but it describes the aquifer; what changes the unit is your plot's vulnerability on the Water Plan map (art. 70.10), and we check it on the viewer.
Agritourisms and holiday lets: going over 12
In a home the Plan gives 1 population equivalent per bed space as a guideline equivalence (art. 70.8, table 12), and we size the plant for the maximum. Above 12 (not with exactly 12), the performance checks and the log of cleaning, maintenance and sludge go to Recursos Hídrics every year (art. 70.11), and pre-treatment includes grease removal. If there is a restaurant kitchen, fats do not go in without their own grease separator first (art. 70.7.e).
What we do
What we fit in Muro, and what others take care of
- A new treatment plant, extended aeration, approved and compliant with the EN 12566 family, as the Balearic Water Plan requires (art. 70.14). We work with all brands; for example, the GRAF one2clean.
- Installation, electrics and documents: the electrics as an authorised low-voltage installation company, and the documents prepared and signed for your architect or technical adviser to file.
- What others do, coordinated: digging the pit, your builder, with the manufacturer's instructions from us in writing; sludge emptying, an authorised waste-management company, as the law requires (art. 70.7.f).
- Service visits: the ones the regulations require or, if the manufacturer asks for more, the manufacturer's (two a year on the GRAF one2clean).
No subcontractors. In Muro we measure the distance to s'Albufera before talking paperwork.

Common questions
Frequently asked questions about treatment plants in Muro
My finca in Muro is near s'Albufera: what documents do I need?
It depends on the bed spaces. Below 12 population equivalents, with the treated water reused on your plot, a responsible declaration to Recursos Hídrics is enough. With 12 or more and 500 m or less from s'Albufera, a wetland in the Water Plan catalogue (Royal Decree 49/2023, arts. 76.5 and 77), prior authorisation is needed, and for it silence means refusal.
Does each bed space of my holiday let in Muro count as one population equivalent?
Yes, as a guideline: in a home the Plan gives 1 population equivalent per bed space (art. 70.8 and table 12 of the Balearic Water Plan) and asks for the capacity to be justified by use and occupancy. We size the plant for the maximum, not the yearly average. A house in Muro with 10 bed spaces in summer needs a plant for 10, even if a couple lives there in winter.
What do the rules require if a house or agritourism in Muro goes over 12 population equivalents?
Three things: the performance checks and the log of cleaning, maintenance and sludge go to the Direcció General de Recursos Hídrics every year (art. 70.11); pre-treatment includes grease removal; and near s'Albufera or a public supply well, prior authorisation is needed. Two 8-bed-space houses with a unit each are not the same as one plant for 16.
Why do you check the vulnerability map before quoting in Muro?
Because 58.5 km² of Muro, virtually the whole municipality, is a nitrate vulnerable zone under Decree 18/2023, and because the Water Plan changes the unit according to the aquifer's vulnerability on your plot: where it is high, only a green area is allowed, and the Plan also lists denitrification and disinfection, recommended up to 12 population equivalents and required above 12 (art. 70.10, tables 13 and 14).
Can I send the finca's rainwater to the treatment plant?
No. Rainwater does not go into the plant (art. 70.7.d of the Balearic Water Plan): it dilutes it and washes the bacteria out. On a finca in Muro with large roofs and patios, rainwater runs in its own network, separate from the foul water, and the plant only takes the house's wastewater.
What upkeep does the plant in Muro need, and what's my part?
Service visits: the ones the regulations require or, if the manufacturer asks for more, the manufacturer's (two a year on the GRAF one2clean), with a report. Emptying: an authorised waste-management company (art. 70.7.f). Your part is checking daily that the light is green and no alarm sounds, and not switching the plant off when you close the house for winter.
