Industry Background

Against growing water‑supply‑demand conflicts, stricter agricultural water‑saving regulations and normalized water‑environment governance, wastewater recycling and reuse has become a critical technical pathway to close agricultural irrigation water gaps and advance green low‑carbon farming. Treated effluent (reclaimed water) processed via biochemical treatment, sedimentation and filtration meets quality standards for farmland irrigation, woodland greening and ecological water replenishment. It effectively substitutes surface‑water and groundwater resources, delivering dual benefits of water‑resource circularity and pollutant‑emission reduction.

Modern reclaimed‑water irrigation workflows cover a complete chain: wastewater purification, reclaimed‑water storage & regulation, booster pumping & distribution, and zoned field irrigation. The whole system integrates industrial controllers, water‑quality monitors, flow meters, soil‑sensing devices and power‑transmission equipment. Nevertheless, traditional irrigation districts commonly suffer from heterogeneous incompatible devices, fragmented datasets, weak process inter‑linkage, delayed control and coarse O&M practices. Low reclaimed‑water utilization prevents standardized, refined digital operation and undermines project performance.

Core Industry Pain Points

1. Heterogeneous Devices & Isolated End‑to‑End Data

The full reclaimed‑water irrigation workflow incorporates wastewater‑treatment PLCs, water‑quality analyzers, pressure‑level transmitters, variable‑frequency pump drives, soil‑moisture sensors and video cameras. Multi‑brand hardware uses disjointed communication protocols and signal types without standardized data interfaces. Independent subsystems create severe data silos across wastewater treatment, reclaimed‑water storage, pressurized conveyance and field irrigation. Cross‑process coordination and unified dispatching become major technical bottlenecks for smart retrofits.

2. Manual‑Driven O&M with Passive Risk‑Prone Operation

Conventional irrigation sites rely on periodic on‑site patrols, manual attendance and paper‑based logs, lacking 24/7 digital monitoring and early‑warning capabilities. Abnormal conditions such as fluctuating reclaimed‑water quality, pipe‑network pressure spikes, pump overload & dry‑running, tank over‑leveling and valve jamming can only be addressed after incidents occur. Without full‑lifecycle digital equipment ledgers, maintenance, failure and repair records are scattered and untraceable. This leads to hardware damage, non‑compliant irrigation and water waste, together with high management costs and latent safety hazards.

3. Rigid Irrigation Logic & Low Resource‑Use Efficiency

Legacy irrigation runs on fixed‑schedule “one‑size‑fits‑all” routines. It fails to dynamically adjust according to reclaimed‑water quality shifts, hydraulic pipe‑network status, field soil moisture, real‑time meteorology and crop water‑demand patterns. Lacking algorithm‑driven decision support, systems cannot allocate water on‑demand. Common problems include flood‑style over‑irrigation and uneven zoned water supply, which waste valuable reclaimed‑water resources, push up energy consumption and compromise agricultural irrigation standards, greatly lowering overall circular‑water‑reuse benefits.
