Sanitary water conservation device

An installation for the intermediate holding and storage of liquid, said installation comprising:

• a sealable housing having an inlet for receiving said liquid and an outlet drain pipe for discharging said liquid, the housing including a front wall and having a height and a width, the outlet drain pipe extending horizontally through a lower opening in the front wall and the outlet drain pipe having a diameter less than the width and height of the housing,
• a holding reservoir pivotally mounted on pivot axis within said housing to receive and temporarily store a quantity of said liquid,
• wherein said holding reservoir is formed as an asymmetrically shaped open bucket adapted to automatically pivot around said axis from a first position adapted for receiving and storing said liquid to a second inverted position where the stored liquid is emptied from a front edge of said bucket into said housing under the influence of gravity once accumulated liquid reaches a sufficient mass, the bucket having a width greater than the diameter of the outlet drain pipe and the bucket having a centroid of plane area and mass moment of inertia to an opposite side of said pivot axis in relation to said front edge, when unladen, and which mass moment of inertia progressively moves during filling from said opposite side toward said front edge to cause the bucket to rotate from the first position to the second inverted position,
• said bucket pivoting for an angle greater than 45 degrees between the first position and the second inverted position,
• said housing includes a gradual and continuously tapered and inclined race incorporated into a floor of said housing and extending gradually and continuously from a position below said pivot axis to said outlet drain pipe to divert said liquid directly to said outlet drain pipe,
• wherein said race has side walls that taper in a side to side direction from an inlet of the race to an outlet of the race so that the distance between the side walls reduces toward the outlet of the race, and the race is inclined toward said outlet drain pipe, and
• said bucket has a front edge which is positioned sufficiently close to said front wall when moved to said second position so that water exiting said front edge of said bucket hits the front wall of the housing so as to cause a two part flow of waste formed by solid material and waste liquid utilizing the housing to concentrate a velocity applied to the waste liquid, with most of the solid material exiting to said outlet drain pipe in a first flow action which, because of the relative dimensions of the front wall, the bucket and the outlet drain pipe, and the water hitting the front wall of the housing in turn forces a portion of the waste liquid up the inclined race, away from the outlet drain pipe to a position below the bucket, and into contact with the housing whereby the waste liquid is returned towards the outlet drain pipe by gravitational force and most waste liquid exiting to said outlet drain pipe as a second flow action;
• and
• wherein said holding reservoir is pivotally mounted remote from and apart from said race so as to provide an uninterrupted fluid flow for the first and second flow action of said waste;
• wherein said housing includes an inspection opening and an integral lid therefor, and
• wherein said housing includes a support bracket and pivot point for said reservoir.
