TANZANIA: SPRING PROTECTION SCHEMES
A series of spring protection schemes, highlighting some of the good and bad aspects of construction:
TOP: Main spring is covered however there is poor drainage of surface water.
MIDDLE: Failure to cover the water means this is not really a spring 'protection' scheme. Poor drainage also.
BOTTOM: Main spring is covered and there is good drainage. This is a high quality construction.
