Building a Climate-Resilient Future: Sustainable Infrastructure and Innovation at Tenwek Hospital

Howard Humphreys (East Africa) Limited was instrumental in the Tenwek Hospital Cardiothoracic Center Infrastructure Improvement Project, championing sustainability, infrastructure, and innovation. Our key areas of involvement included design of a new water supply system with a capacity of 700 m³/day, implemented a new wastewater treatment plant with a 570 m³/day capacity, using advanced technologies like the moving bed bioreactor system, extended the power distribution network from an existing hydropower plant to support new hospital facilities. By aligning with key UN Sustainable Development Goals—SDG 6 (Clean Water and Sanitation), SDG 7 (Affordable and Clean Energy), and SDG 9 (Industry, Innovation, and Infrastructure)—the project significantly enhanced Tenwek Hospital’s capacity to deliver cutting-edge healthcare. As a state-of-the-art referral center, renowned for its advanced cardiothoracic services, Tenwek Hospital now stands as a regional leader, ensuring access to clean water, reliable energy, and resilient infrastructure that support both the hospital’s needs and the broader Tenwek region. 

Howard Humphreys Core Focus Areas 

Sustainability:

Water Supply: Implemented a new water supply system, including a raw water pumping main and a conventional water treatment plant with a capacity of 700 m³/day. The project emphasized efficient water management, which is critical for sustainable development. 

Wastewater Treatment: Implemented a new wastewater treatment plant with a 570 m³/day capacity, using advanced technologies like the moving bed bioreactor system. This system ensures that effluents meet required standards, minimizing environmental impact. 

Infrastructure: 

Electrical Systems: Extended the power distribution network from an existing hydropower plant to support new hospital facilities. The project assessed and confirmed the capacity of the existing distribution infrastructure to meet future demands. 

Stormwater Management: Developed a new stormwater conveyance and disposal system, ensuring that the new hospital facilities would effectively manage rainwater, reducing the risk of flooding and erosion. 

Innovation: 

Advanced Treatment Technologies: The use of moving bed bioreactor technology in wastewater treatment represents an innovative approach to ensuring high standards of effluent treatment, aligning with modern environmental sustainability practices. 

Alignment with UN Sustainable Development Goals (SDGs): 

SDG 6: Clean Water and Sanitation – Access to clean water is a critical issue in East Africa, where millions lack safe drinking water and adequate sanitation. The Tenwek Hospital water and wastewater treatment project addresses this challenge by improving the hospital’s facilities and expanding clean water access to surrounding communities. With a new water treatment capacity of 700 cubic meters per day and a wastewater treatment plant of 600 cubic meters, the project directly supports SDG 6, enhancing health and quality of life.

 SDG 7: Affordable and Clean Energy – Extending the power distribution network from a hydropower plant supports SDG 7 by providing sustainable energy. This project reduces reliance on fossil fuels, offering a stable and clean energy source crucial for medical services. It also lowers the hospital’s carbon footprint, contributing to global clean energy efforts. 

SDG 9: Industry, Innovation, and Infrastructure – The Tenwek Hospital project, led by Howard Humphreys, exemplifies alignment with SDG 9 through innovative infrastructure development. By enhancing the hospital’s facilities with advanced technologies and sustainable practices, Howard Humphreys sets a benchmark in the industry for innovation, resilience, and sustainable industrialization. 

 Impact and Statistics: 

  • Water Treatment –The new system provides a capacity of 700 m³/day, ensuring a reliable water supply for the hospital’s needs. 
  • Wastewater Management –The advanced treatment plant handles 570 m³/day, significantly improving the hospital’s environmental sustainability. 
  • Energy Efficiency –By utilizing the existing hydropower plant, the project ensures that the hospital’s energy needs are met sustainably, reducing reliance on non-renewable energy sources.
