THE USE OF DIFFERENT TYPES OF PIPES FOR TRANSMISION OF WATER IN KENYA

Abstract.
Pipeline water transmission has replaced the traditional means of water conveyance in Kenya
e.g. walking to the streams or using donkeys to carry water. This has greatly boosted the supply
of portable water for use especially in irrigation and domestic use. The main advantages of
pipeline water transmission include efficiency in supply, saving of time and effective
management of the scarce resource.
Effective management of water through an efficient supply system has however been hampered
by the ignorance of the engineering guidelines in pipeline installation. According to statistics
from the Assistant Director in the section of water services providers, almost 65% of the water
tapped by the water services providers has been going to waste through leakages from pipe
bursts and usually goes unaccounted for. This is a great issue of concern since Kenya is a water
scarce country. The country only uses about 3 billion cubic meters of water in a year and the
little water must therefore be conserved for economic use.
Improvement of the different pipe types has taken place over the ages to facilitate the effective
transmission of water. Plastic pipes e.g. UPVC, HDPE, polyethylene and PPR have emerged and
their use have greatly increased in Kenya due to cost effectiveness and convenience in their
installation and application. Analysis of the balance between the costs of the various pipe types
and their ability to be applied effectively in different ground rock conditions in Kenya is a
major component of this project. Correct piping would save the country a great amount of water.
This entails standard methods of installation and joining if pipes to mitigate leakage at joints and
pipe bursts as frequently witnessed in various regions in Kenya.
