Turnkey I-RAIN® Rainwater Harvesting & Recycling Systems
Turnkey commercial and industrial I-RAIN® rainwater recycling systems engineered to reduce municipal water dependence, ensure local authority compliance, and earn GBI green building certification.
Introduction to Rainwater Harvesting Solutions
Rainwater harvesting is an essential alternative for supplying businesses and commercial facilities with non-potable water. By capturing and storing rainwater for irrigation, vehicle/floor washing, and toilet flushing, you significantly lower environmental impact and reduce high municipal water reliance.
At I Controls Solution, our experienced team provides turnkey design, sizing, and installation services tailored to your specific facility requirements. We utilize high-quality, durable materials and fully operable technology to ensure maximum system efficiency.
Beyond initial design and installation, we provide ongoing system maintenance and technical support to keep your rainwater harvesting infrastructure operating at peak performance year-round.
COMMERCIAL WATER CHALLENGES
Why Commercial Facilities Need Engineered Rainwater Recycling
Addressing high municipal water tariffs, green building mandates, and supply reliability for commercial developments.
FINANCIAL SAVINGS
⚠️ Escalating Commercial Water Tariffs
Commercial and industrial water tariffs continue to rise rapidly. Turnkey rainwater harvesting replaces costly municipal supply for non-potable usage.
SUSTAINABILITY MANDATES
⚠️ Strict GBI Green Building Mandates
Modern commercial developments require green building points. Integrated rainwater systems deliver essential credits for GBI certification.
SUPPLY RELIABILITY
⚠️ Unreliable Municipal Water Disruptions
Unscheduled water cuts impact facility operations. Harvested rainwater stored on-site provides independent backup supply for utility operations.

4-Step Turnkey Rainwater Recycling Process
Roof Catchment & Pre-Screening
High-flow pre-screen filters trap leaves and coarse debris before rainwater enters clean storage.
Automatic First-Flush Diversion
Self-draining diverters automatically isolate initial dirty roof wash, diverting silt away from storage.
Modular & High-Capacity Tank Storage
Filtered rainwater is stored across modular RAINPRO systems, I-RAIN® PRISM units, or dedicated tanks.
Controlled Discharge & Optional Recycling
Stored water is discharged at controlled rates for local authority or pumped back for reuse.
Rainwater Harvesting System That Exceeds Your Needs
Tailored water recycling setups engineered for high-rise commercial towers, industrial factories, public institutions, and landed residential developments.
Commercial Towers & Shopping Malls
