Problem and fix

The problem this solves.

  1. 01
    The problem

    Treated wastewater has nowhere to go, but there is spare land.

    How it is fixed

    The water is spread along ridges planted with fast-growing trees. The trees drink the water and use its nutrients, so nothing seeps into groundwater.

How it works

Step by step.

  1. 1

    Plant

    Fast-growing trees are planted on ridges.

  2. 2

    Apply

    Treated wastewater flows in the furrows.

  3. 3

    Use

    Trees take up water and nutrients.

Questions

Frequently asked questions.

Is this technology proven?

Yes. It is at ready level 7 of 9, which means: tested in the field. Grows a green belt from wastewater.

Can we try it on our own water first?

Yes. We test a sample in our NABL-accredited lab and, where it helps, run a small trial on your site before you invest in a full plant.

Do you supply and install it?

Yes. We design, supply, install and start up the system, train your staff, and our lab checks the treated water.
