3.6 Acres · Permanent RainGun · 74 Units · March 2026 · Erode, Tamil Nadu · Goat Farm Fodder Cultivation
In February 2026, Dr. Sachi came to Thumba Agro Technologies through our website. He is an orthopedic doctor who runs a goat farm in Erode, Tamil Nadu — both as a personal passion and as an additional income source. His farm carries more than 800 goats, but he did not have sufficient green fodder to feed them. He was buying fodder from nearby farms and personally handling the cutting and transport himself — an ongoing cost and workload he wanted to eliminate with a proper irrigation solution for his own fodder plot.
After a complete field study, our team designed a permanent RainGun system with fixed pillars for his 3.6-acre fodder plot. But the project came with real engineering complications. The only available water source — an open well at 60 feet depth — sat 800 meters away from the plantation field, and yielded a minimum of just 40,000 litres per day. Of that, 10,000 litres per day had to be reserved purely for the goat farm's drinking water, leaving only 30,000 litres per day to work with for irrigation.
The 800-meter pipeline distance added a second challenge: frictional loss. Water travelling that far through a pipeline loses pressure along the way, so the system had to be engineered to develop 5 kg/cm² more pressure than a standard-distance RainGun setup just to deliver full, uniform coverage at the far end of the line.
Using our fluid engineering knowledge, we balanced all three constraints — the limited 30,000 litre/day irrigation budget, the 800-meter distance, and the extra pressure requirement — into a single working design. We successfully erected 74 RainGuns as a permanent setup across the full 3.6 acres in March 2026, giving Dr. Sachi a self-sufficient fodder supply for his goat farm without touching the herd's drinking water allocation.

"This project was solved with fluid engineering, not just equipment. An 800-meter pipeline from a 60-foot open well yielding just 40,000 litres a day, with 10,000 litres reserved for 800 goats to drink — that leaves very little room for error. We had to calculate the exact extra pressure needed to beat frictional loss over that distance, then design 74 RainGuns to work within a 30,000 litre/day budget. That is what our vast fluid engineering knowledge is for."

Pumping water 800 meters from the open well to the plantation field causes significant frictional loss inside the pipeline — pressure drops the further water travels. Using our fluid engineering knowledge, we calculated the exact additional pressure needed to compensate for this loss and designed the system to develop 5 kg/cm² more pressure than a standard short-distance RainGun setup, ensuring full, uniform coverage even at the far end of the 800-meter run.
Dr. Sachi's open well yields a minimum of 40,000 litres per day at 60 feet depth. Since his farm supports over 800 goats, 10,000 litres per day is reserved exclusively for drinking water. The remaining 30,000 litres per day was budgeted for the RainGun irrigation system — so the entire 74-RainGun layout was engineered to operate efficiently within that water allowance, not the full 40,000 litres.
Yes, with the right engineering. A 60-feet open well yielding only 40,000 litres per day is considered a minimum-yield source. By carefully sizing the pump, pipeline and pressure to match the 30,000 litres per day available for irrigation, we successfully supplied all 74 RainGuns across 3.6 acres without over-drawing the well or affecting the goat farm's drinking water supply.
The farm was designed as a permanent installation with fixed pillars, positioned to give complete, uniform coverage across the full 3.6 acres with no dry patches. Given the constrained water budget of 30,000 litres per day and the 800-meter pipeline pressure requirement, our field study determined that 74 RainGun positions on fixed pillars was the correct layout to irrigate the entire plot efficiently within those limits.
Before this system, Dr. Sachi purchased green fodder from nearby farms for his 800+ goats and personally handled the cutting and transport — an ongoing cost and workmanship burden. With his own 3.6-acre fodder plot under permanent RainGun irrigation, he now cultivates sufficient green fodder on-site, removing the recurring purchase cost and the manual cutting-and-transport work entirely.
Low-yield wells, long pipeline distances and split water demands are exactly what our field study and fluid engineering process is built to solve.
