Why ECOTED

Efficiency that turns into savings

High efficiency

Aerobic treatment that removes over 90% of the sewage's organic load, measured as BOD and COD.

Water savings

The treated water comes back fit for reuse and cuts the building's potable water consumption by up to 70%.

No civil works

Designed to withstand soil loads, it can be buried in the garden without any civil works, fully plug'n play. Above-ground versions are also available.

Plug'n play installation

Sized by our specialists, installation is quick and practical, leaving the system ready the moment it is put in place.

Applications

Where ECOTED comes into play

A compact plant designed for environmental and legal compliance, for projects with demanding standards.

Single-family homes

A decentralized, single-family sanitation solution for homes that want cutting-edge sewage treatment technology — or even plan to reuse their treated sewage.

Commercial and industrial

Buried or above ground, ECOTED can be installed in corporate facilities, ensuring a high-performance, odor-free system with low OPEX — saving water through reuse.

Communities, neighborhoods and residential complexes

ECOTED can be applied in collective settings, sized according to the existing population, becoming a definitive, odor-free solution with low OPEX and a high guarantee of quality in sewage treatment — and even reuse.

How ECOTED works

From sewage leaving the house to treated effluent — step by step in the compact plant buried in the garden.

      Stage 01

      Digging the trench

      Dig/excavate the trench to the dimensions given in the product manual.

      Stage 02

      Preparing the bedding

      Prepare the bedding with 20 cm of No. 1 crushed stone and 20 cm of coarse sand, forming a firm, level base.

      Stage 03

      Placement and anchoring

      Place the tank in the trench and anchor it if necessary, ensuring the inlets and outlets are aligned.

      Stage 04

      Partial backfill

      Add sand up to half the tank's height, surrounding it evenly.

      Stage 05

      Filling

      Fill 50% of the tank's volume with water to balance pressures during backfilling.

      Stage 06

      Inlet and outlet

      Connect the system's inlet and outlet piping according to the hydraulic design.

      Stage 07

      Power supply

      Connect the power supply for the air blower — it keeps the aerobic stage of treatment running.

      Stage 08

      Backfill and landscaping

      Complete the final backfill and landscaping — the system stays buried and invisible in the garden.

      Frequently asked questions

      ECOTED Compact WWTP: what you need to know

      What is ECOTED?
      ECOTED is a high-performance compact domestic sewage treatment plant based on the Japanese Johkasou technology. It delivers treated effluent fit for reuse and/or discharge with maximum safety.
      How does sewage treatment work in ECOTED?
      Treatment is aerobic and 100% biological, removing over 90% of the organic load (BOD and COD). The treated effluent is fit for reuse, discharge into a water body or soil infiltration.
      Can the treated water be reused?
      Yes. The treated water is fit for non-potable reuse, such as landscape irrigation. This reuse reduces the project's potable water consumption, saving on the water bill and strengthening the ESG agenda.
      Does ECOTED meet the standards and get approved by environmental agencies?
      Yes. ECOTED is designed within Brazilian standards ABNT NBR 17.076/24 and CONAMA 430, and is a SABESP-approved product, which makes it easier to get the system approved by regulatory agencies throughout Brazil.
      Does ECOTED fit projects with little space?
      Yes. As a compact plant, ECOTED takes up little area and adapts to projects of different sizes — buried or above ground — supporting environmental compliance even where space is limited.
