Taking Care of Consumption Fluctuation

Taking Care of Consumption Fluctuation

The problem of the fluctuation of consumption and the balancing of pressures when the load suddenly is increased without adequate means of meeting the emergency is one which is often present for the water works superintendent. This is especially the case where the supply is by means of a trunk line. In this case when the pressure suddenly leaps to the peak and continues so for an unusual length of time, the superintendent will be at his wits’ end to keep the pressure at the services up to normal and avoid complaints from consumers.

A solution suggested in the paper published on page 107, of this week’s issue of FIRE AND WATER ENGINEERING is an extremely simple one and also has the advantage of being comparatively reasonable in cost. It is through the establishment of balancing reservoirs in the distribution system. This plan, as described by Mr. Phillips, has proved very successful in the Los Angeles water works and has been instrumental in saving that department from the necessity of heavy expense in paralleling the trunk line with another or by the equally great expense of enlarging the cast iron mains of the present line. By the use of the balancing or, as the author aptly expresses it, the “kickback” reservoir or tank, the “rest period” during the idle time of the night hours is made to work toward maintaining the proper pressure by the filling up of these tanks, which produce an adequate supply during the active hours as needed.

The practical solution of this problem, as worked out in Los Angeles, will be found of great interest to other water works men who are confronted with the same difficulty.
