1. An apparatus for operating a filter system of a swimming pool in proportion to the degree of water contamination, said apparatus comprising:
- overflow tank means for receiving water from the swimming pool as a function of the number of persons entering into the swimming pool;
filter means;
variable output pump means;
pipe means for interconnecting the swimming pool, the overflow tank means, the variable output pump means and the filter means in a substantially closed loop;
sensor means for detecting changes in the level of water within the overflow tank means in response to the number of persons in the swimming pool and for generating a first value representative thereof;
computer means comprising memory means for storing values representative of at least one parameter selected from the group consisting of;
natural loss per unit of time, fresh water added, and water loss due to spillagemeans for processing the first value and the memory stored values to derive a second value representative of the degree of water contamination; and
means for controlling the output of the variable output pump means in response to the second signal.

Abstract
A method and apparatus for operating a filter system of a swimming pool in proportion to the degree of contamination of the water in said pool by processing a signal representative of the number of persons within the pool and other values characteristic of the pool and the filter system to derive a signal for controlling the output of said filter system.
