ABSTRACT
The Science and Technology (S&T) Train will be a self sustaining entity. At any given time at least 50 persons
will be on board. A clean supply of water is essential to the facility. This design project will be the development
of a system that will use a 40 000 litre stainless steel water tanker as a base. The purpose of the project is to
establish the best approach to pressurise the water supply to the coaches of the train (4 Bar) and how to treat the
water supply to be safe for drinking water, using as inline water purification and filtering system.
Different design configurations will be investigated, by employing different pressure pumps and different filters for
purification. This will be done to find the best cost effective and lowest maintenance options. An investigation
will also include the usage of solar power to drive the system.
