4 Acres · Permanent Pillar RainGun · Ongoing Since April 2026 · Alangulam, Tenkasi, Tamil Nadu · Vegetables, Fodder & Maize
Mr. Aravind, a return NRI from Alangulam, Tenkasi, Tamil Nadu, came to Thumba Agro Technologies through a website search to install a permanent RainGun system for his 4 acres of own land. After a complete WhatsApp conversation covering his system requirements and facility demands, our team finalised a rough plan and drawing and sent it to him. Once the project was confirmed, our team travelled to his destination for a full field study.
The field study revealed that water scarcity was the main issue. Mr. Aravind had 4 borewells, each yielding a minimum of just 10,000 litres per day. His old open well — 60 feet deep — could collect a maximum of 40,000 litres, but water leakage in that well made it an unreliable source on its own.
To solve this, we decided to construct a 1-lakh-litre capacity ground-level water tank, fed by all 4 borewells, and installed one 10HP submersible high-pressure motor compatible with the RainGun system. This consolidated the farm's scattered, low-yield water sources into a single dependable buffer large enough to run a full permanent RainGun layout.
As of July 2026, 60% of the work — both the water tank and the RainGun system — is complete, and is expected to finish within 20 days. Mr. Aravind has planned the land as a multicrop farm: vegetables, fodder for dairy or CNG bio-fuel use, maize, and more.

"Four borewells at 10,000 litres a day each, and a leaking 60-foot well — none of that is a reliable water source on its own. Consolidating everything into a single 1-lakh-litre tank with one high-pressure submersible motor is what turns scattered, low-yield sources into a system that can actually run 90 RainGuns. This project is still underway, but the design problem is already solved."

For Mr. Aravind's project, the initial requirements and facility details were discussed over a complete WhatsApp conversation. Based on that, Thumba's team prepared a rough plan and drawing and sent it to him for confirmation. Only after the project was confirmed did the team travel to Alangulam, Tenkasi for the actual field study — which then refined the design based on real site conditions like the water source situation.
Mr. Aravind had 4 borewells, each yielding a minimum of only 10,000 litres per day — not enough individually for a reliable permanent RainGun system. Thumba's solution was to construct a 1-lakh-litre capacity ground-level water tank that all 4 borewells fill into. A single 10HP submersible high-pressure motor then draws from this consolidated tank to run the RainGun system, smoothing out the variability of any one borewell.
Mr. Aravind's old open well was 60 feet deep and could collect a maximum of 40,000 litres, but it suffered from water leakage — making its actual usable yield unreliable. Rather than depend on a leaking well, Thumba designed the system around a new 1-lakh-litre ground-level tank fed by the 4 borewells, giving a much larger and more dependable water buffer for the RainGun system.
Mr. Aravind has planned his 4 acres for vegetables, fodder (for dairy or CNG bio-fuel use), maize and other crops. A permanent RainGun system suits this kind of multi-crop plan well because the fixed pillar layout and 1-inch RainGuns provide uniform, rainfall-like coverage across the whole field regardless of which crop is planted in a given section.
The system uses 90 RainGuns in total across the 4-acre permanent pillar layout, each delivering 70 LPM through a 1-inch nozzle, with 10 RainGuns running simultaneously at 1000 LPM and 5 bar pressure from the 10HP motor. Running only a portion of the RainGuns at any one time — cycling through zones — lets a single 10HP motor deliver full working pressure without needing a much larger, costlier motor to run all 90 heads at once.
Yes. Mr. Aravind, a return NRI, first reached Thumba through a website search and worked out the full system requirements over WhatsApp before a rough plan and drawing were sent to him for confirmation. Thumba's team then travelled to the site for a field study once the project was confirmed — showing that overseas or returning customers can get a fully designed system without needing to be on-site for the early planning stages.
We'll study your borewells, wells and land layout, then design a tank and pumpset combination that actually delivers reliable pressure for your RainGun system — even from overseas, we can start with a WhatsApp conversation.
