Middle Route of South‑to‑North Water Diversion completes its 2025–2026 water supply mission

According to China South‑to‑North Water Diversion Group Corporation, published on 4 November 2026, the Middle Route of the South‑to‑North Water Diversion Project concluded its 2025–2026 water supply assignment on 31 October. 

A total of 7.264 billion cubic metres of water was delivered to receiving areas in Henan, Hebei, Beijing and Tianjin. The scheme serves 27 large and medium‑sized cities along its corridor, with nearly 118 million people benefiting from the supply.

China South‑to‑North Water Diversion Group Middle Route Company monitored water demand across the receiving zones, adhered to the annual supply schedule and carried out refined transport scheduling on a monthly basis. 

Digital twin systems for the Middle Route were rolled out during the operational cycle. An ice forecasting and prediction model refined transport arrangements across temporal and spatial dimensions during the ice period, lifting operational efficiency. 

The system delivered 1.648 billion cubic metres of water in this phase, exceeding the planned volume by 158 million cubic metres.

Alongside regular deliveries to intake points, surplus water available before and during flood seasons was channelled into 15 local watercourses and zones including the Qinghe, Jiayu River, Fuyang River, Qili River and Zhi River. 

The ecological replenishment operation surpassed targets set for summer releases and sustained ecological stability for rivers and lakes along the route.
