Ingeniería de las Aguas is an engineering firm based in Palmares, Alajuela. We design, build, optimize and rehabilitate wastewater treatment plants and improved septic systems, design pumping stations, sewers and drainage, prepare operational reports, and handle wastewater and environmental permits for residential, commercial, industrial and urban projects.
Every region of Costa Rica poses different problems: a long dry season in Guanacaste, steep hillsides and heavy rain in the South Pacific, a high water table on the Caribbean, dense condos in the Central Valley. Pick your area below to see what usually matters there.
Guanacaste
Start with our Guanacaste overview, then go to your town:
- Tamarindo and Langosta: hotels, condos and restaurants on flat land near the estuary.
- Flamingo, Potrero and Brasilito: hillside villas and condos, small beach lots.
- Playas del Coco and Ocotal: restaurants downtown, condos and villas on the hills.
- Nosara: rental villas, retreats and boutique hotels.
Puntarenas: Nicoya Peninsula, Central Pacific and South Pacific
- Santa Teresa, Mal País and Montezuma: fast growth on tight lots, streams and slopes.
- Jacó and Herradura: condo towers, hotels and hillside developments with plants to keep compliant.
- Dominical, Uvita and Ojochal: steep lots and heavy rain.
Limón: South Caribbean
- Puerto Viejo and Cahuita: low, wet land and a climate calendar unlike the Pacific.
Central Valley
- Atenas and Grecia: hillside homes on former farmland, close to our base in western Alajuela.
- Escazú and Santa Ana: gated condos with their own plants, hillside homes and urban stormwater.

These pages cover the areas where foreign owners most often ask us for help, but they are not the only places we work. We serve western Alajuela, the Greater Metropolitan Area, Guanacaste, Puntarenas (Central Pacific and the Southern Zone) and Limón. See all our services, and send us the location and a short description of your project on WhatsApp or through our contact page.
Regions
- Septic systems and water for homes in Atenas and GreciaAtenas and Grecia attract retirees and families who want Central Valley weather, a view and some land. Their wastewater and water questions are about hillside lots, rural water associations and old farmland turned into homes, and we are based right next door.See the region →
- Septic systems for hillside homes in Dominical, Uvita and OjochalOn the southern Pacific coast most homes are built on steep, green hillsides with ocean views, far from any sewer, in one of the rainiest stretches of the Pacific. Here the drain field, not the tank, decides whether a system works.See the region →
- Wastewater treatment plants and septic systems in Escazú and Santa AnaEscazú and Santa Ana are the west side of San José where many foreign families and executives live, in gated condos, hillside homes and new mixed-use buildings. Some streets have sewer, many properties do not, and condo plants carry legal duties.See the region →
- Wastewater treatment and septic systems in GuanacasteGuanacaste combines a long dry season, scarce water and fast tourism growth, and very little public sewer. This overview explains what that means for hotels, condos and homes, and links to our pages for each beach area.See the region →
- Wastewater treatment plants for condos and hotels in Jacó and HerraduraJacó and Herradura are the closest beaches to San José, with condo towers, hotels, a marina and gated communities. Many already have a treatment plant, and the main job is keeping it compliant, upgraded and ready for full weekends.See the region →
- Wastewater systems in Puerto Viejo and CahuitaOn the South Caribbean coast, land is low and flat, the water table is close to the surface and it rains in every month. Septic systems that work on the Pacific often fail here, so the design has to start from the water table.See the region →
Towns and services
Guanacaste
- Septic systems and treatment plants in Flamingo, Potrero and BrasilitoIn Flamingo the challenge is the hill: ocean-view villas and condos on steep, rocky lots. In Potrero and Brasilito it is small lots and busy beachfront businesses on low ground. This page covers both, and how we help.Open →
- Septic systems and small treatment plants in NosaraNosara is a place of rental villas, yoga retreats and boutique hotels spread through the forest on unpaved roads. Their wastewater systems face irregular occupancy, heavy rains and growth that outpaces the original design.Open →
- Wastewater systems in Playas del Coco and OcotalPlayas del Coco mixes a busy commercial strip of restaurants and dive shops with condos and homes climbing the hills, and Ocotal adds hillside villas and resorts. This page explains what each needs and how the rules apply in the canton of Carrillo.Open →
- Wastewater treatment and septic systems in Tamarindo and LangostaTamarindo packs hotels, condos, restaurants and rental homes onto flat land beside an estuary, where the water table, sandy soil and peak-season crowds test every wastewater system. Here is what owners and boards in Tamarindo and Langosta usually need, and how we help.Open →
