Testing and chemicals from one provider
We manage both the testing and the treatment; we don’t pass your problem on to another provider.
Built for the peninsula’s water
The water here is hard and corrosive, and we formulate for it.
Figures we can back up
What we publish comes from our invoices, not from estimates.

Where do you work?
We serve Quintana Roo from our base in Cancún, and Mérida. Campeche and Tabasco are handled as projects on request. From Cancún to Tulum, the site visit for a quote is free; outside that area, we quote it as a special visit plus travel expenses. See our coverage →
Can you operate my wastewater treatment plant?
Yes: monitoring, dosing, sampling, reports and plant maintenance.
Why does it matter that you know the local water?
The peninsula’s aquifer is very hard, with sulfates and salinity near the coast. Equipment specified for a different water chemistry deteriorates quickly here.
Need a water treatment solution?
An engineer reviews your facility and sends you a written proposal.
