Definitions

  • This invention relates to water conservation, and may find application in the recovery of water which has been used but which has not been heavily contaminated, by purifying it at a location at or close to the point of use, and returniinng the purified and cold drinking water to the point of use or a location close to the point of use.
  • Purified and cold water is easily obtained from relatively pure sources, although in some regions of the world other sources are used, e.g. sea water which is desalinated. Virtually all relatively pure water sources are ultimately derived from precipitation, whether this is used directly (Surface rain or melt water, rivers) or indirectly (stored in aquifers). Direct use is limited by precipitation rate, and indirect use, while initially providing another supply, is also limited thereby in the long term, because otherwise the stored water is not replenished. Thus as many regions are experiencing, it is difficult to ensure that an increasing demand for clean cold water is still met satisfactorily, and the importation of water from other areas and/or the odoption of less pure water sources are strategies which come under consideration.
  • the invention provides a local water management system comprising recovery means for recovering waste water from the first point of use and/or surface water from a collection point in the local vicinity of the first point, and storing it in a container, a water purification system in the local vicinity of the first point of use.
  • the said at least one storage tank may be serially connected between the outlet of the purification system and the first point of use, or between the outlet of the purification system and a second point of use in the local vicinity of the first point.
  • the returning means prefferably be arranged so that it also receives additional water from a remote source, for example mains water or even water from a desalination plant, so that when the input to the container or the output of water from the purification and cooling system is insufficient to meet the demand, this additional water acts as a supplement.
  • a remote source for example mains water or even water from a desalination plant
  • the additional water may be supplied to the point of use without storage. Alternatively however, it may be received and stored in the said tank of the returning means, as indicated in more detail hereafter.
  • Pump means may be provided for pumping water from the recovery means through the purification system to the returning means and/or for supplying purified water to the first or second point of use.
  • the purification system comprises at least one filter for removing paniculate matter and/or a reverse osmosis filter an/ or an ultra violet treatment unit Preferably all three types of filter are present.
  • the osmosis filter should be placed to act after the particulate matter has been removed; the ultra violet filter will be located at any position relative to the other filters.
  • the system will comprise an integral structure having at-leasi two separate compartments defined therein, the compartments being occupied by. or providing, at least two of the of the purification system, the container, and a said storage tank.
  • the invention provides a module for use in a system according to the first aspect, comprising an integral structure having at least two compartments, at least one said compartment forming a water tank, and water purification system being located in at least one said compartment.
  • Figure 1 is a schematic cross section of an integral structure incorporating a water purification system and water tanks which may be used for example in a domestic water management system according to the present system:
  • FIG 2 is an enlarged and somewhat more detailed view of the purification system shown in figure 1;
  • Figure 3 is a cross sectional view of a storage tank which may be used in the water management system of the present invention.
  • FIG. 1 shows part of a water management system suitable for a house, for example.
  • a tank 1 having three separate compartments each with an access lid 10 is shown fitted at and below ground level, and is placed in the vicinity of the house.
  • This tank is typically of plastics or fibre glass material, although it could be constructed of other materials such as concrete.
  • a pipe 20 serves to direct waste and/or surface water to a first compartment 2.
  • the waste water will be typically be derived from the outlets of hand basins and baths within the house, but not more heavily soiled water from water closets.
  • the surface water may be obtained from gutters, trapped gulleys, and/or ground drainage channels in forecourts, drives, car parking areas etc.
  • a water purification system 4 is essentially located in compartment 3, but includes a course partical filter 41 located in compartment 2. (A course filter at the input to compartment 2 could replace or supplement filter 41).
  • a pipe 42 directs the the water from the filter 41 via an ultra violet filter 43 and a pump 44 to a fine partical filter 45. typically a sand filter.
  • the output of the filter 45 is connected through a reverse osmosis filter 46 to a storage tank defined by the third compartment 5.
  • Both filters 45 and 46 have backwash facilities whereby accumulated contaminants may be flushed via pipes 49 to a conventional waste (soil drainage system).
  • Compartment 2 has an overflow 21 for directing excess water to a conventional soil drainage system, if necessary, although the system would be designed so that under normal circumstances all water directed to the compartment 5 via the filter.
  • Water from the third compartment is directed by pipes 51 and the pump 44 via a variable cooling system 47 direct to the cold taps within the building for drinking water as would be the supply from the water company.
  • the supply would also be used for any other domestic purpose.
  • the same supply would in any event continue direct to the cold water tank 6 ( Figure 3) in the house.
  • the third compartment has an overflow 50 so that excess water supplied thereto may be led away, preferably to a soakaway so that ground water sources may be replenished; a non-return valve may be necessary.
  • the tank 6 contains a lower ball valve 61 for receiving mains water through pipe 63 from the water company.
  • the purified water from the third compartment 5 is pumped through pipe 51 to an upper ball valve 62. and so fed to the tank 6 in preference to the mains water.
  • the upper ball valve may contain an actuator switch for operating the pump 44.
  • the purification system is easily accessible for servicing, and in view of this and the fact that electrical components may be involved, it may be found preferable omit both the central compartment 3 and the purification system, and locate the latter above ground, for example in a separate compartment. Alternatively, the whole of the structure 1 could be placed above ground. For larger installations, for example large office blocks, industrial units and factories, it would be advantageous to provide and install the tanks and/or the different parts of the water purification system as individual components.
  • the mains water input has been described as passing through the tank 6.
  • the tank could be omitted and the purified water used to supplement the mains supply at the point of use.
  • the pump will produce sufficient pressure to allow the purified water to be injected at the point of use.
  • the above system installation would in any event comply with the relevant water companies and the public health regulations to date.
  • the purified water can additionally or alternatively be supplied to a different point of use
  • the system may be considered to be particularly advantageous when fresh water supplies are scarce, and when even the water supplied to the first point of use may be derived from a costly source such as a desalination plant.
  • the invention has unlimited applications.
