Subterranean Irrigation System (STIS)

A Water-Saving, Growth-Enhancement Device for Irrigating Trees

The STIS technique irrigates trees in a similar fashion as drip irrigation; however, it introduces the water below the soil surface in a closed cylindrical chamber with a permeable fabric in the bottom, resembling a micro drywell. It decreases evaporation losses and promotes deep-root growth. It uses standard emitters residing inside the STIS canister.

STIS Patent Pending.

Benefits

Conserves water due to minimal evaporation losses

Increases growth since no water is wasted through evaporation (Study at ASU Polytechnic showed that trees with the STIS grew 5% faster than trees with conventional, surface drip irrigation)

Promotes deep-root growth, reducing the chances of trees blowing down (and eliminating the associated costs with replacing and replanting lost trees)

Minimizes weeds around tree due to the absence of surface water

Keeps emitters cleaner (less chance of plugging) and protected from pets and rodents

Provides an ideal path for irrigating trees with grey water, since the discharged water is introduced inside the canister isolated from public contact

History

This patent-pending unit, and several variations, have been under development for several years. This development effort has been funded and carried out by Control Systems Innovation, Inc. and its staff, an engineering/product development firm in existence since 1983. Units have been donated to several users for evaluation purposes. In every case where the tree was healthy prior to the time of installation, the trees have continued growing.
