💧 MALAYSIA'S FIRST 4-IN-1 INTEGRATED TANK
PRISM 251 – Compact All-in-One Rainwater Tank System
Pioneer modular rainwater harvesting architecture combining pre-screen filtration, first-flush diversion, auto top-up, and 250L to 300L storage in a single space-saving unit.
4-in-1 Compact Rainwater Recycling Architecture
The I-RAIN® PRISM 251 integrates four essential rainwater treatment functions into a single modular footprint, built for space-constrained commercial and residential developments.
Physical interception of leaves, twigs, and coarse organic matter.
Isolates initial contaminated roof wash carrying dust and heavy silt.
Robust composite polyethylene construction engineered for reliable water containment.
Integrated domestic top-up valve and overflow discharge pipework.
