At this Alakananda hydro power facility, the head of operations noticed that inefficient pump systems were failing to remove accumulated sediments from the desilting chambers. These chambers, which are critical to the filtration and protection of downstream equipment, were gradually becoming less effective.
Enhancing Desilting Efficiency at the Alakananda River Hydro Power Dam with Goodwin ANZE Submersible Slurry Pumps
At this Alakananda hydro power facility, the head of operations noticed that inefficient pump systems were failing to remove accumulated sediments from the desilting chambers. These chambers, which are critical to the filtration and protection of downstream equipment, were gradually becoming less effective.
As a result:
-
Sediment-laden water reached the turbines, causing frequent wear and tear.
-
Downtime for turbine maintenance increased, reducing power generation output.
-
Maintenance costs surged, straining operational budgets.
-
Environmental sediment management targets became harder to achieve.
Recognizing the need for a specialized, high-performance solution, the plant leadership turned to Goodwin, a globally respected name in slurry pump technology and desilting applications.
Assessment and Pump Recommendation by Goodwin India
Upon invitation, Goodwin’s engineering team conducted a detailed on-site assessment of the desilting infrastructure. Their analysis revealed that the existing pumps lacked the design strength to handle:
-
High sediment concentrations.
-
Abrasive and coarse particles.
-
Large volumes of water under variable flow conditions.
To address these issues, Goodwin recommended the installation of two 100mm ANZE submersible slurry pumps—specially designed for heavy-duty sediment handling in hydro power facilities.
Key Features of the Goodwin 100 ANZE Submersible Slurry Pump
-
Inbuilt agitators to resuspend settled solids, ensuring continuous sediment flow.
-
Non-clog impellers for uninterrupted operation, even with high debris loads.
-
Twin volute casings to reduce radial loads and extend pump life.
-
High solid-handling capacity, ideal for Himalayan sediment conditions.
-
Submersible design eliminates the need for extensive above-ground infrastructure.

Installing Goodwin Pumps in Desilting Chambers
After approval from plant leadership and successful procurement, two Goodwin 100 ANZE pumps were installed directly in the desilting chambers. The implementation process included:
-
On-site technical support from Goodwin India’s engineers.
-
Training for plant operators on pump maintenance and performance optimization.
-
Real-time monitoring during initial operation to fine-tune pump positioning and flow parameters.
This collaborative approach ensured that the pumps were deployed effectively and that plant personnel could confidently manage the system moving forward.
"The Goodwin pumps have successfully removed the settled sediments from our desilting chambers, improving the efficiency and reliability of our power house.."
