Ensuring Clean Water Access for 125,000 People Through Engineering Excellence

In Tanzania’s semi-arid lowlands, the communities of Same, Mwanga, and Korogwe districts have long faced significant challenges in accessing clean and reliable water, leading to health risks, economic stagnation, and social inequities.

To address this urgent issue, the Same-Mwanga-Korogwe Water Supply Project was initiated to provide a sustainable water solution for 37 villages and two small towns across the Pare Mountains. The project involved constructing a 130 km water supply network, two high-capacity pump stations, and a water treatment plant capable of processing 69,000 m3 per day.

By leveraging over six decades of engineering expertise, C.R.I. Pumps played a crucial role by supplying state-of-the-art pumping solutions tailored to the project's unique requirements. This initiative has ensured a sustainable water supply and improved public health, supported agriculture, and fostered economic and social development.

This case study highlights this transformative project's challenges, solutions, implementation process, and outcomes.

Problem Statement

Access to clean water has been a persistent issue in the Same, Mwanga, and Korogwe districts, severely affecting health, agriculture, and economic development. The existing water supply infrastructure was inadequate, resulting in unreliable access to safe drinking water. An urgent need for a sustainable, high-capacity water distribution system was identified to combat waterborne diseases and enhance the quality of life for thousands of residents.

Solution Identification & Selection

Recognizing the magnitude of the challenge, C.R.I. Pumps' channel partner engaged with stakeholders to identify an efficient and sustainable pumping solution. A dedicated team of product developers, technical experts, and engineers conducted an extensive study of project requirements, focusing on performance metrics, site conditions, and long-term sustainability.

Pumping Solutions Provided:

• Six Twin Impeller Horizontal Split Case Pumps coupled with high-efficiency 450 kW, 4-pole motors
• End Suction Pumps (ECW) for optimized efficiency
• Vertical Turbine Pumps (VT) & Horizontal Multistage Pumps (HMS) for effective water transportation

Pump Specifications:

• Model: SCW 150/600 C N K K G 450KW M 4P 3 PB
• Flow Rate: 455 m3/h
• Head: 234 m
• Power: 450 kW, 4-pole, 415V, 3-phase
• Weight: 4500 kg
• Dimensions: 3.5m (L) x 1m (W) x 2m (H)

These pumps were strategically chosen to ensure efficient water extraction from rivers, lakes, and aquifers, guaranteeing a consistent water supply across the region.

Implementation

The project was executed in two phases:

Phase 1:

• Construction of intake structures, a water treatment plant, raw and clear water pumping stations, a storage tank at Kisangara, and service reservoirs serving nine villages.

Phase 2:

• Expansion to 28 additional villages and two small towns, including new pumping stations and gravity-fed storage tanks.

Production & Testing:

The project required engineering precision and expertise. A remarkable feat was manufacturing a single-piece casting weighing 2000 kg. To ensure reliability, third-party engineers from Tanzania visited C.R.I. Pumps’ state-of-the-art manufacturing facility in India to validate the design and performance metrics before shipment.

Results & Impact

Once fully operational, the project will significantly enhance water accessibility for 125,000 people, delivering:

• Access to Clean Water: A drastic reduction in waterborne diseases and improved public health.
• Sustainable Water Supply: Reliable and consistent water access for domestic, agricultural, and sanitation purposes.
• Economic & Social Upliftment:

Conclusion

The Same-Mwanga-Korogwe Water Supply Project is a testament to the power of engineering, innovation, and international collaboration in addressing critical infrastructure challenges. By leveraging high-performance pumping solutions, C.R.I. Pumps played a pivotal role in securing clean and reliable water access for thousands of people.

This initiative not only underscores the impact of strategic planning and advanced technology but also exemplifies how global partnerships can drive meaningful change in underserved regions, ultimately transforming lives and fostering sustainable development.
