The 2024 Water Services Regulatory Board (WASREB) report highlights that Kenya’s national non-revenue water (NRW) rate stands at 43%. This alarming figure poses a major challenge for water service providers. It affects financial sustainability, slows down infrastructure development, and limits access to clean water across the country.
Key Contributors to NRW
Several factors contribute to NRW, including:
- Leakages – Often caused by substandard supply materials and poor installation.
- High water pressure – Inadequate distribution management increases pressure, leading to pipe bursts and leaks.
- Inaccurate meter readings – Faulty measurements impact revenue collection and financial planning.
A Japanese Innovation for Leak Prevention
To tackle leakage issues, the Japan International Cooperation Agency (JICA) partnered with SK-KAWANISHI, a renowned Japanese pipe joint manufacturer. In January 2023, they launched a pilot project in Kericho County to test the effectiveness of SK-KAWANISHI’s mechanical pipe joints. These joints were specifically designed for Kenya’s water infrastructure.
Key Benefits of SK-KAWANISHI’s Pipe Joints
- Quick and easy installation – No heat, adhesives, or specialized tools required.
- Time efficiency – Each joint takes just five minutes to install, even in difficult conditions.
- Durability – Withstands high pressure, ensures stable connections on angled pipes, and works with different pipe materials.
Successful Implementation and Impact
The pilot project involved installing SK-KAWANISHI’s joints in a newly built 12-kilometer water pipeline in Ainamoi, Kericho County. The Kericho Water and Sanitation Company (KEWASCO) collaborated on this initiative.
The results were impressive:
- 20% reduction in leakage rates
- 75% decrease in repair frequency compared to traditional methods
- Improved cost savings due to faster installation and fewer repairs
- Over 80% consumer satisfaction thanks to better water quality and stable pressure
Additionally, faster response times to leaks improved overall service delivery. As a result, customer satisfaction among water utility users increased significantly.
Expanding the Reach of This Technology
To further address Africa’s NRW crisis, SK-KAWANISHI has been collaborating with the Water Services Providers Association (WASPA). The company has also participated in major industry events such as the African Water and Sanitation Association (AfWASA) International Congress and Exhibition. In November 2024, it officially registered its business in Kenya and began supplying its technology to local water service providers.
A Commitment to Sustainable Water Management
Mr. KAWANISHI Akihiro, CEO of SK-KAWANISHI, expressed confidence in their solution:
“Our innovative pipe joint technology directly tackles NRW in Kenya and will revolutionize the industry. Our mission is to ensure that every drop of water reaches its destination without waste.”
JICA remains dedicated to Kenya’s development by introducing high-quality Japanese products and solutions. Moving forward, the agency aims to foster more success stories that contribute to the country’s water sustainability goals.
