Why JSL
From the drainage network to the treatment plant of an off-grid house. Clean, well-laid work, compliant with regulations.
Total-oxidation treatment plants and Graf tanks for homes off the mains sewer, sized to the number of people and left compliant with regulations.
Downpipes, gutters and drainage channels to collect and carry away rainwater, avoiding pooling, leaks and damage to the home.
Inspection chambers, traps, gullies and pumping with Jimten material so the network drains well, even when the water has to be lifted.
When the treated water is discharged to the ground or a watercourse, we handle the discharge permit with Recursos Hídrics of the Govern de les Illes Balears.
We coordinate it with your plumbing: water and drainage from the same team, with no gaps between trades.
We attend blockages, bad smells and faults, and maintain treatment plants and pumping so they keep working and last.
Before you decide
From a home's drainage network to the treatment plant of an off-grid house in the countryside. This is what we are asked for most in Mallorca, all to the Spanish CTE DB HS-5 and with material that lasts.
A complete network of downpipes, collectors and chambers for wastewater, and gutters and drainage channels for rainwater. We size it with the right fall so it drains well and gives no trouble.
There are loads of country houses and estates in Mallorca that aren't on the mains, and the question is always the same: what do we do with the wastewater? What works best for me is a total-oxidation treatment plant. I mostly fit the Graf one2clean units — compact and they run beautifully — and the oneAdvanced when there are more people or more flow. I pick the tank, a Carat or a Platin buried in the ground, based on how many people live in the house. I leave it running, odour-free and with the paperwork in order.
We fit inspection chambers, traps, gullies and pumping of waste or rainwater with material from brands such as Jimten, so the network works even when the water has to be lifted.
When the treated water is discharged to the ground or a watercourse, a discharge permit is usually required, which in the Balearics is handled by Recursos Hídrics of the Govern de les Illes Balears. We advise you and, where applicable, handle the paperwork.
How we work
We look at your home, the ground and the water outlet, and recommend the right solution. Fixed, free, no-obligation quote.
We build the network, treatment plant or channels with the right fall and quality material, leaving everything tested and the site tidy.
Where applicable, we handle the discharge permit, and hand over the installation working, with warranty and invoice.
What we do
From the drainage network to the treatment plant of an off-grid house.
Downpipes, collectors and chambers for wastewater, to the Spanish CTE DB HS-5.
Total-oxidation treatment plants and Graf tanks for homes off the mains sewer.
Gutters, downpipes and drainage channels to carry away rainwater without damage.
Unblocking, bad smells and maintenance of treatment plants and pumping across Mallorca.
When it makes sense
I'll be straight with you: if you've got a house in the countryside with no mains sewer, sooner or later you'll need a proper treatment plant — the old-style cesspit is neither legal nor pleasant to be near. And in any home, an old or badly laid drainage run ends up giving you blockages, stench and damp at the worst possible moment.
The island's heavy rain also calls for good rainwater drainage: well-sized gutters and drainage channels prevent pooling, damp and damage to the home.
We leave everything to the Spanish CTE DB HS-5 and, where there is discharge to the ground, with its permit from Recursos Hídrics of the Govern. Whether it is a new treatment plant, a network renovation or a blockage, we look at it and give you the best solution.
Common questions
It is a small treatment plant for homes with no access to the mains sewer: it treats the wastewater before discharge or reuse. We install total-oxidation plants and Graf tanks, sized to the number of people, and leave the system ready and compliant.

Quality
For treatment plants I stick with Graf: mostly the one2clean units and Carat or Platin underground tanks. The drainage pipe is usually Adequa, and the chambers, traps and channels, Jimten. Material that doesn't give you trouble — that's what matters.
