Introduction

Agriculture heavily depends on reliable irrigation infrastructure, especially in regions where rainfall is seasonal or insufficient. Large pump houses are commonly used to transfer water from rivers, reservoirs, or dams into irrigation canals supplying agricultural lands.

High energy consumption.
Frequent motor failures.
Inefficient water distribution.
Delayed fault detection.
Poor maintenance planning.
Water leakage and overflow.
Lack of operational transparency.
To overcome these challenges, a comprehensive digitization strategy was implemented for a large agricultural pump house.
