1. What is this item?

An overhead water tank is an elevated storage vessel—typically made of HDPE (plastic), ferrocement, or RCC—mounted on a stand or tower. It provides gravity-fed distribution, ensuring consistent water pressure for irrigation, livestock, and domestic use without continuous pumping.

2. How is the Quantity Estimated?

• Storage Volume Needed (in liters or cubic meters): Based on daily farm water demand (irrigation + livestock + domestic).

o E.g., a 10 ha farm might need 20,000–50,000 L of working storage.

• Number of Tanks: Total volume ÷ standard tank size (e.g., 10 kL, 20 kL modules).

• Stand Capacity: Height (3–6 m) determines pressure; choose stand design accordingly.

3. What are the Cost Components?

• Tank Body (HDPE shell / ferrocement lining / RCC casting)

• Support Structure (steel frame or masonry tower)

• Foundation & Platform (concrete pad, anchor bolts)

• Inlet/Outlet Plumbing (valves, float switch, overflow piping)

• Access Ladder & Safety Railings

• Installation Labor (crane rental if large tanks, skilled masons/welders)

• Surface Treatment (UV-stabilizer for plastics, waterproofing for masonry)

4. What are the Going Rates & Per Unit Cost?

• Plastic HDPE Tanks (10 kL): ₹15–₹25 per liter → ₹1.5–₹2.5 Lakh

• Ferrocement Tanks (10 kL): ₹12–₹18 per liter → ₹1.2–₹1.8 Lakh

• RCC Tanks (10 kL): ₹10–₹15 per liter → ₹1.0–₹1.5 Lakh

• Steel Stand / Masonry Tower: ₹20,000–₹40,000 per meter of height

• Installation & Plumbing: ₹15,000–₹30,000 per tank

• Total (10 kL HDPE + 4 m stand): ~₹2.3–₹3.3 Lakh

Cost per liter of installed, elevated capacity: ₹23–₹33/L

This provides reliable, gravity-fed water distribution for all your farm blocks—keeping pumps off during operation and ensuring steady pressure when you need i
