These rainwater harvesting modules for water conservation create an underground storage volume for captured rainfall. By storing filtered runoff for later use, a project can reduce demand for treated mains water and keep bulky storage equipment out of the visible landscape.

Practical Resource Conservation
The modules are manufactured in PP and connect into tanks sized around the available catchment and intended demand. A well-planned system combines storage with pretreatment, overflow control, pumping and a separate non-potable supply line. Conservation performance depends on matching tank capacity to local rainfall patterns and actual water use.
Where the System Is Used
Suitable applications may include irrigation, site cleaning, toilet flushing and other locally approved non-potable demands. The underground format is useful for residential, commercial and landscape projects that need to preserve usable surface area while managing rainfall close to where it falls.

Installation Principle
Prepare the excavation and structural base to the engineer’s design, assemble the interconnecting modules, then wrap the tank for its intended function. A permeable geotextile configuration supports infiltration; a sealed geomembrane configuration supports storage and reuse. Inlets, outlets, pretreatment, inspection access, ventilation, backfill and cover depth must be specified for the site.
