Inside Cancún’s urban grid, houses connect to the sewer. Step outside it and the picture changes: Isla Blanca and the Costa Mujeres coast, country lots along the road to the airport and Puerto Morelos, ranches and weekend homes around Alfredo V. Bonfil and the Leona Vicario road, and many new private subdivisions where the network has not arrived. Here every house needs its own sealed treatment system.
Beach houses on sand with high water tables, where tanks must be sealed and anchored.
Country lots and gated communities south of the city, beyond the network.
Weekend homes and ranches inland, with larger plots for wetlands and irrigation.
Private developments waiting for sewer: systems designed to be disconnected later.
Compact plants for rentals and houses with terraces close to the tanks.
Drip irrigation with treated water instead of losing it into the rock.
Around Cancún the ground changes within a few kilometres. On Isla Blanca and the coast, sand and a shallow water table mean tanks can float when the ground floods, so we anchor them and keep vents above surge level. Inland, limestone rock makes excavation the main cost and turns any leak into a direct path to the aquifer. Both cases need sealed, tested tanks — never an open absorption pit.
Some subdivisions around Cancún will be connected to the network in coming years. We design systems with a bypass and connection point so the house can switch to the sewer later without breaking up the garden, and with the treated water already routed to irrigation, which stays useful either way.
