Water Purification, Reverse Osmosis and Desalination Plants

On this coast, municipal water is intermittent in many areas and absent in others, and well water is hard, brackish and often contaminated as seawater pushes into the aquifer. Hotels, condos, beach clubs, island projects and large villas solve it with their own plant: reverse osmosis for brackish wells, desalination for seawater, plus softening and disinfection. We build the well, the plant, the storage and the brine disposal as one system.

2026 costs: villa or small boutique system (2–10 m³/day) $250,000–$900,000 MXN; brackish-well reverse osmosis plant for a hotel or condo (20–150 m³/day) $900,000–$4.5M MXN; seawater desalination plant (50–500 m³/day) $3.5M–$25M MXN including intake, pre-treatment and brine well.

What We Build

Wells & Intakes

Well drilling and testing, beach wells for seawater intake, pumps and the CONAGUA concession file.

Pre-Treatment

Sand and multimedia filters, cartridge filtration, antiscalant dosing and softening to protect membranes.

Reverse Osmosis & Desal

Brackish and seawater RO trains with energy recovery, sized for peak occupancy with redundancy.

Disinfection & Remineralisation

UV, chlorination and remineralisation so the water is safe and does not corrode pipes.

Storage & Distribution

Cisterns, elevated tanks, pressure systems and separate networks for potable, service and irrigation water.

Brine Disposal

Brine and backwash disposal through permitted wells or blending, designed with your environmental consultant.

Brackish well or seawater?

Most inland projects draw from wells, and the water gets saltier the closer you are to the coast and the deeper or harder you pump. A brackish-water RO plant uses far less energy and costs less than seawater desalination, so it is the first choice wherever the aquifer allows it. On beachfront sites, islands such as Holbox, Cozumel and Isla Mujeres, or where wells have turned saline, seawater desalination with energy recovery is the reliable option. We test the source water before we design, because the salinity decides the membranes, the pressure, the energy bill and the brine volume.

Designed for operation, not just for start-up

Redundancy: two trains or a standby unit so a membrane change does not leave the hotel without water.
Corrosion: stainless and duplex steel where salt water flows, ventilated plant rooms away from the sea breeze.
Energy: energy recovery devices, variable-speed pumps and the option of solar to cut the running cost.
Remote monitoring: conductivity, pressure and flow alarms on the operator’s phone.

Frequently Asked Questions

In 2026 a seawater desalination plant for 50–500 m³/day costs about $3.5M–$25M MXN including intake, pre-treatment and brine disposal. A brackish-well reverse osmosis plant for a hotel or condo is much cheaper, around $0.9M–$4.5M MXN.

Yes. Groundwater extraction requires a CONAGUA concession, and brine or backwash disposal must be permitted. Large plants may also need environmental authorisation. We prepare the technical files.

It depends mainly on salinity and energy price. Brackish RO typically uses a fraction of the energy of seawater desalination; we give you an operating-cost estimate per m³ with the proposal.

Yes. A compact system with filtration, softening, reverse osmosis for drinking water and UV disinfection is common in villas with well water or unreliable supply.
