Abstract
A large pipeline system is usually one of the components of a water distribution
system. This will carry water from the sources to the distribution reservoirs,
often by means of costly pumping stations, since local topography may include
areas of high ground.
The pumping timetable should be designed to accommodate the fluctuation of
energy costs over a twenty-four - hour period, with preference being given to
pumping during off-peak hours. This solution may not always be possible,
however, because of operating constraints it could be necessary pumping during
peak energy-cost periods, and so the optimal solution will have to recommend
the most effective period for pumping, bearing in
