Р 4-8 - PYANJ: Irrigation (Part 1)
Boitudasht number 0 pumping station has been operating since 1976 and is currently in an advanced state of degradation. At present only two pump units, out of four, are operational. The station structures and external facilities are in very poor condition. The pumping station is considered to have little or no remaining life and is highly ineffective in delivering irrigation water to its command area.
The pumping station is located in the path of a mud-flow stream and successive flow events have cased considerable damage to the station
- Reconstruction of the pumping station structure
- Replacement of 2 pump units
- Construction of mud-flow intercepting canal
- Construction of reinforced concrete wall for protection against mud-flow and landslide.
Schedule of benefits is presented in part 2 of this subproject description below.

Р 4-8 - PYANJ: Irrigation (Part 2)
As the water in the Pyanj River is very turbid and transports large amounts of sediment, irrigation networks in the project area have become silted and canals have reduced delivery capacity. The collector-drainage network is silted resulting in poor drainage of irrigated land leading to water logging, increased salinity and subsequent reduction in crop yield and, therefore, income.
Mudflows occur annually in the spring and cause increased siltation of the irrigation network. The mudflow management infrastructure at the intersection of a flow channel and the Kelyanchi irrigation canal is largely dysfunctional and in need of rehabilitation.
Rehabilitation of the primary irrigation and drainage network within Nuri Vahdat, Mehvar and Namuna Jamoats by removal of sediment from priority lengths of delivery canal and drainage collector as follows:
|Canal / Collector||Length to be Rehabilitated (km)|
|Shakari Nav Canal
Supply canal of 1 May Pump Station
Tail end of Kelyanchi Canal
Rehabilitation of mudflow channel sluice gates and construction of mudflow check dam in Kelyanchi Canal at the intersection of the canal with the R14 Pyanj to KT road, as illustrated in the figure below.
