High-Performance Septic Systems

Treat wastewater on-site, and free up the lot

High-performance septic that treats wastewater above local code requirements and turns it into clean, odorless water you can reuse. The treatment happens below the surface (no open sewage, no smell) and the finished system looks like a landscaped water garden, while using a fraction of a standard drainfield's footprint so you can fit more homes on the lot.

A Living Landscape

A park that purifies, not a treatment plant

Our systems clean water through plants, soil, and microorganisms while doubling as colorful, biodiverse green space.

Why SeaTop Builds Wetlands

A long-term alternative to costly treatment plants

Conventional treatment plants are costly, energy-intensive, and disruptive. Our water purification systems operate with minimal energy, prevent odors and groundwater contamination, and reduce nitrate pollution.

Unlike mechanical plants, our wetlands add value to communities, functioning as beautiful, colorful green spaces and parks with natural amenities.

  • Increase living-unit density per lot
  • Cost-effective and low-energy
  • Prevents groundwater pollution and odor
  • Positive carbon footprint
  • Easy to maintain for many years
  • Removes nitrate, the #1 groundwater pollutant
How We Do It

From assessment to monitoring

Each system is engineered for the site, placeable on ground, roof, or balcony.

Site Assessment

Wastewater loads, soil conditions, hydrology, and available land.

Tailored Design

Surface flow, subsurface flow, or hybrid wetlands to suit the site.

Construction & Supervision

Engineered installation with professional oversight.

Commissioning & Monitoring

Testing, adjustments, and operator training for reliability.

What We Do

Versatile across every context

Our wetlands serve residential, resort, municipal, agricultural, and industrial projects. Beyond treatment, they restore ecosystems, improve biodiversity, and create recreational or educational spaces.

  • High-efficiency septic systems
  • Municipal treatment (stand-alone or park-integrated)
  • River and lake rehabilitation
  • Industrial and agricultural effluents
  • Sludge and landfill leachate
  • Nitrate removal from drinking water
  • Bird sanctuaries, eco-parks, and ornamental lakes
  • Stormwater control and eco-hydrology
Benefits

Treatment that gives back

Chemical-free, scalable, and highly efficient: plants, soils, and microbes do the work of machinery, blending function with beauty.

Environmental

Restores ecosystems, increases biodiversity, and lowers carbon footprint.

Water Quality

Produces clear water suitable for irrigation and landscaping.

Economic

Lower construction and O&M costs than traditional treatment plants.

Community Value

Doubles as gardens, ponds, and natural parks on ground, roofs, or lakes.

User Friendly

Minimal technical operation required.

Investment-Ready

Scalable, long-term infrastructure that adds value.

Certified Laboratory Testing

Verified to strict water-quality standards

  • Turbidity reduction (clarity)
  • Biological oxygen demand (BOD)
  • Chemical oxygen demand (COD)
  • Pathogen elimination (E. coli, coliforms)
  • Nutrient removal (nitrogen, phosphorus)
  • Deployed in Campeche, Veracruz & Mexico City
Questions & Answers

What developers ask us most

Free-flow wetlands are land-intensive and mosquito-prone. Our engineered systems are compact, efficient, and odor-free.
