Description

WASTE WATER CONTROL SYSTEM FIELD OF THE INVENTION This invention consists of a wastewater control system and diverter valves for use in the control of wastewater for recycling purposes.

ANTECEDENTS OF THE. INVENTION It is increasingly recognized, even in countries with a traditional temperate climate, that water is not an infinitely available resource. Global weather patterns appear to be changing and, in some areas of the United Kingdom, there has been a drastic fall in the amount of rainfall, with the consequence that consumers are required to take measures to limit their water consumption, conserving by this means the supplies. The primary purpose of the water supplied by the distribution networks is human consumption, and it is necessary that the water for this purpose be of potable quality. However, it is recognized that non-dirty or contaminated domestic wastewater, sometimes called "gray" water, can be reused for secondary purposes including; the supply of tanks for P1014 / 99MX toilets, water to irrigate the gardens and laundry and washing purposes. However, not all of this water is necessarily adequate for these purposes and, therefore, there is a need for a water control system that can selectively allow "waste water to flow directly into a main drainage system or, otherwise, , to a storage tank for eventual reuse and supply a secondary demand.

OBJECTS AND ADVANTAGES OF THE INVENTION According to one aspect of the present invention, the non-soiled domestic wastewater control system comprises a storage tank that includes a means for supplying secondary demand discharges and admission pipe for non-soiled domestic waste water, where the intake pipe includes a selective diverter valve and a pump means and the storage tank includes a level detector means operably connected to the pump means, thereby, during In use, the wastewater is selectively directed to the pump medium and is pumped into the storage tank or passes to the drain of the main pipe if the storage tank is full, when this is detected by the level detecting means. According to another aspect of the invention, a P1014 / 99MX diverter valve and pump unit for use in a domestic, non-dirty wastewater control system, consists of a housing that defines a water intake medium and a water discharge medium, and a pump chamber which includes a pump means, the housing includes a valve means for selectively directing the water from the inlet means to the discharge means or to the pump chamber, an overflow means being provided between the pump chamber and the pump medium. discharge of water. During use, the outlet of the pump means is preferably connected to a storage tank for supplying the secondary water demand discharges. The storage tank preferably includes a level detector means operably connected to the pump means to inactivate it, when the storage tank is full. However, the discharge of the pump medium can be a direct connection to secondary water demand discharges, instead of indirect through the storage tank. The pump chamber of the diverter valve and pump unit preferably also includes a level detecting means, such as a float switch operably connected to the pump means, whereby the pump means does not it lights up P1014 / 99HX that the pump chamber fills with water. Preferably, the pump medium inlet includes a filter means to prevent any solid material suspended in the water from entering the pump medium. In a modality, the valve means consists of a valve chamber "which includes an inlet orifice and discharge orifices, giving rise, respectively, to the water discharge means and to the pump chamber, and a valve member consisting of a hinge which it is pivotally mounted for movement between the sealing coupling positions with one or the other of the holes. Preferably, however, the valve member consists of a cylinder mounted in a rotary manner having ducts formed therein, the cylinder being mounted for axial rotation in a housing "which defines the entry and discharge orifices, for movement between positions in which one or the other of the discharge orifices is opened and the other is closed, the entrance hole remaining open in any position. The water discharge means preferably includes a vent hole to prevent any trapped air from creating a deposit of powdery solids and to prevent the flow of water through the discharge means. For convenience, the ventilation hole is combined with the overflow medium.

P1014 / 99MX The capacity of the pump medium must be sufficient to allow the discharge water to be supplied at a speed that is approximately the speed of entry, so that the pump chamber is never empty, despite the flow of influx continuous of water, nor be over-supplied, in spite of the continuous drainage of water, resulting in excess water that runs until it is discharged through the overflow medium. It is possible to provide two or more pumps to strengthen the discharge capacity; The pumps can be selectively driven according to the speed of flow. The pump discharges can be connected to a common discharge tube through a suitable manifold. The pump means are preferably powered by a low voltage direct current electricity source, which may be provided by the main power source, through a suitable voltage conversion device, such as a step-down transformer, or for a rechargeable power source. The storage tank, which is preferably mounted on the roof to allow the supply by gravity to secondary demand discharges, can be provided with a source of water from the main reserve pipe, through a control valve P1014 / 99MX operated with float. To avoid any risk of residual water contaminating the source of the main piping, the control valve can be mounted on the upper end of a console attached to the side wall of the tank, the float being connected to the control valve through of a crank driven member having a portion positioned in the vertical direction. The console preferably includes a horizontally extending lower arm, with a slotted outer end, the vertical portion of the operating member passing through the slot and being guided by an axial movement therein, whereby the inlet tube of the main pipe is kept on top of the side wall of the tank. This console constitutes another aspect of the present invention.
