(1) A major project takes a few years to construct.
(2) Carrying out the activities detailed above, prior to actual implementation, may
take anything between 5–10 years.
(3) The time taken for project completion is detailed out later, but very often, when
completed, the facility provided already reaches its design capacity (as designed
20 years ago) very quickly, i.e., even before it starts operation, it is already
under-designed.
(4) The project’s useful life starts after its completion, and will be providing
infrastructure (water) facilities for the next 50 to 100 years or more, as discussed
later.
Thus, the assessment of infrastructure (water) requirements should really take a
long term view. Even if a mere 50 years is considered, it is still 50 years beyond T o
and not only 20 years!
5.3.2 Assess the Water Availability
Certainly, before anybody spends money, it is necessary to know how much money
is available. Thus, an assessment of the water available over the country will need to
be carried out, starting from rainfall to river flows and groundwater data.
5.3.3 Preliminary Matching of Resources and Requirements
Once the two assessments above have been carried out, a preliminary matching may
be carried out to check on the feasibility of our dreams.
If the projected water requirements exceed water availability, this means that at
some time, there will be a possible water shortage, unless the water demand is
reviewed or some external means of producing water (water recycling, desalination,
etc.) is brought in.
If the projected water availability exceeds water requirements, this means that
with a well-planned infrastructure build up, it should be possible to meet all the water
requirements of the projected forecast.
New technology makes an on-going appearance. As such, it is difficult to foresee
what type of technology will be used in the future. Churchill may have a good
argument, but instead of being wishful thinking, this forecasting exercise does bring
down to earth, both planners and decision makers:
• what is the infrastructure capacity that has to be implemented for the future?
• are conservation measures required?
• what are the constraints (natural or otherwise) in bringing about such possible
future development scenarios?
