Tenwek Water Project
1. Rainwater Harvesting for Tenwek Campus
Background:
Rainwater is an important source of water for Africa and for Tenwek where approximately 10-20% of what is available is currently harvested. This means that the primary source for a substantial fraction of the Hospital requirement is river water. Tenwek produces its own intravenous (IV) fluids (about 24,000 liters per year) for surgery and other medical procedures and treatments, but the river water cannot be pre-processed enough to be effectively used in the current system. With the need for more IV fluids, additional rainwater must be harvested as the supply.
Mission Statement:
Design a system to increase rainwater harvested at Tenwek. This will involve decisions on the amount to be collected, the economics involved, and the design of the system. The system should be easily maintained by the hospital staff. The project should highlight the tradeoffs available to the customer in deciding on a final system.
2. Solar Water Heating for Tenwek Patient Wards
Background:
For patient living quarters Tenwek uses solar water heating. The hospital has so far been unable to expand its solar water heating capacity to match the expansion of the inpatient housing, so about half of the patients live without hot water.
Mission Statement:
Design a solar water heating system for the Tenwek campus. The system should be manufactured using materials and processes readily available at the Tenwek shop, or in the region. The required capacity is for approximately XX liters per day at YY degrees C. The final design will include specification of all necessary hardware.
