Abstract
The water saving system consists of a collection tank (13) and a storage tank (16) and means for collecting, filtering, and transfering rainwater to the storage tank for domestic use. <IMAGE>
Description
THE WATER SAVING SYSTEM
THIS INVENTION RELATES TO A SYSTEM TO COLLECT AND UTILISE
RAIN WATER.
MILLIONS OF GALLONS OF DRINKING WATER ARE WASTED OVER THE
YEARS BY USING IT TO FLUSH TOILETS.FOR HOUSEHOLDS AND
BUSINESS PREMISES FITTED WITH A WATER METER, IT CAN BE VERY
EXPENSIVE.AS BRITAIN HAS A HIGH LEVEL OF RAINFALL1 IT SEEMS
THE IDEAL PLACE TO HAVE AN INVENTION TO USE SOME OF THE
RAINWATER NORMALS WASTED DOWN THE DRAIN TO FLUSH TOILETS,
AND VIA FURTHER CLEANSING AND FILTRATION, OTHER DOMESTIC pTs pOSES.
ACCOPsDING TO THE PRESENT INVENTION THERE IS PROVIDED A
SYSTEM DESIGNED TO COLLECT AND USE RAI.ÁTER TO FLUSH
TOILETS.COMPRISING A COLLECTION TANK,A STORAGE TANK1 MEANS FOR TRANSFERING WATER FROM THE COLLECTION TANK TO THE
STORAGE TANK, MEANS FOR CONTROLING WATER LEVELS, THE STORAGE
TANK BEING ADAPTED TO AUTOMATICALY REVERT TO MAINS WATER
IN PERIODS OF LOW RAINFALL.
A SPECIFIC EMBODIMENT OF THE INVENTION WILL NOW BE DESCRIBED
BY WAY OF EXAMPLE WITH REFERENCES TO THE ACCOMPAWYING DRAWINGS IN WHICH:
FIGURE 1 SHOWS THE STORAGE'TANK AND THE COLLECTION TANK
IN POSITION ON A BUILDING,USING MAINS WATER SUPPLY.
FIGURE 2 ILLUSTRATES THE FLOW OF P'JMPED RAIN WATER AFTER
RAINFALL.
FIGURE 3 SHOWS THE SYSTEM FILLED TO CAPACITY.
FIGURE 4 SHOWS THE SYSTEM USING MAINS WATER, INSTALLED IN A
PROPERTY WHERE THE STORAGE TANK CAN BE PLACED LOWER IN
HEIGHT THAN THE COLLECTION TANK THEREFORE ALLOWING RAIN
WATER TO FLOW BY GRAVITY AND NOT NEEDING TO BE PUMPED.
FIGURE 5 ILLUSTRATES THE GRAVITATIONAL FLOW OF RAIN WATER
AFTER RAINFALL.
FIGURE 6 SHOWS THE SYSTEM FILLED TO CAPACITY.
MECHANICALY FED SYSTEM.
REFFERING TO THE DRAWINGS,AS RAIN FALLS ONTO THE SLOPING
ROOF OF A PROPERTY,IT COLLECTS IN THE GUTTERING AND FLOWS
ALONG TO AND DOWN THE DRAINPIPE 12.BY MEANS OF CUTTING A
SECTION OF PIPE AWAY AND INSTALLING A COLLECTION TANK 13
RAIN WATER IS COLLECTED AND STORED IN SMALL QUANTITIES AT
THE SIDE OF THE BUILDING.WHEN THE WATER RISES TO A SUITABLE
LEVEL, IT ACTIVATES A WATER PRESSURE SWITCH 14 AND SENDS
A SIGNAL TO A WATER PUMP 15 TO RUN FOR A SET TIME TO EMTY
THE TANK 13 INTO A LARGE STORAGE TANK 16 IN THE LOFT.
WHEN THE TANK 16 IN THE LOFT IS FULL, IT DISABLES THE PUMP
BY MEANS OF A MICRO SWITCH 17 CONNECTED TO A FLOATING BALL
VALVE 18.THE PUMP 15 CAN BE MAINS POWERED OR SOLAR POWERED,
NOT SHOWN.FILTERS 19 ARE INCORPORATED ALONG THE WAY TO
STOP LEAVES AND RUBBISH CLOGGING THE SYSTEM.A TRAP DOOR 20
IS USED PERIODICALY CLEAN OUT THE TANK 13 OF SEDIMENT BY
LEAVING IT OPEN WHILE IT IS RAINING.IF THERE IS NO RAIN
FOR SOME TIME AND THE TANK 16 IN THE LOFT BECOMES LOW ON WATER,ANOTHER BALL VALVE 21 CONNECTED TO THE MAINS WATER
SUPPLY 22 WILL AUTOMATICALY OPEN TO KEEP THE WATER IN THE
TANK AT A MINIMUM LEVEL.THE EXISTING MAINS WATER SUPPLY
TO THE TOILET CISTERN IS BLOCKED OFF,AND REPLACED WITH THE
SUPPLY OF WATER IN THE TANK 16.EXISTING PIPES CAN BE USED
AS LONG AS THEY ARE BLOCKED OFF TO THE MAINS WATER SUPPLY.
GRAVITY FED SYSTEM
WHERE IT IS POSSIBLE TO INSTALL A WATER TANK AT A LOWER
HEIGHT THAN THE COLLECTION TANK,KND A HIGHER POSITION THAN
THE TCILET CISTERN, THE GRAVITY FED SYSTEM HAS THE
ADVANTAGES OF BEING CHEAPER AND SIMPLER TO INSTAL AND
MAINTAIN.SOME BUILDINGS CAN BE ADAPTED TO ACCEPT A TANK WITHOUT TOO MANY PROBLEMS.COMERCIAL PROPERTTES COULD
GREATLY BEBEFIT.SMALLER HOUSES COULD USE THE TOP HALF OF AN
AIRING CUPBOARD TO HOUSE THE TANK.NEW HOUSES COULD HAVE
A PURPOSE DESIGNED SPACE.
AS WITH THE MECHANICAL SYSTEM,THE RAIN WATER IS COLLECTED
IN THE COLLECTION TANK 13 ON THE OUTSIDE OF THE BUILDING.
IT IS CONNECTED BY MEANS OF A PIPE TO THE LARGER TANK 15.
AS THE WATER LEVEL RISES WHEN IT RAINS,IT FLOWS TO THE
LARGER TANK 16 BY MEANS OF GRAVITY.WHEN THE LARGE TANK 16 IS
FULL,A BALLCOCK 23 CLOSES THE SUPPLY OF RAIN WATER CAUSING
ANY SURPLUS WATER IN THE SMALL COLLECTION TANK 13 TO
OVERFLOW INTO THE DRAINPIPE 12.AS WITH THE MECHANICAL
SYSTEM THE WATER LEVEL IS NOT ALLOWED TO FALL BEYOND THE
MINIMUM LEVEL BY MEANS OF A BALLCK 21 CONNECTED TO THE
MAINS WATER SUPPLY 22.
DETATCHED AND SEMI DETATCHED PROPERTIES CAN INCREASE THE
SUPPLY OF RAINWATER TO THE SYSTEM BY FITTING THE COLLECTION
TANK TO A WALL AT THE SIDE OF THE BUILDING,AND CONNECTING
IT VIA ADDITIONAL GUTTERINGTO BOTH THE FRONT AND REAR OF THE
BUILDING.
Claims (5)
1, A WATER SAVING SYSTEM COMPRISING A STORAGE TANK, AND MEANS Or
COLLECTING AND TRANSFER INC RAIN WATER TO THE SAID TANK FOR USE VIA PLUMBING,FOR DOMESTIC AND INDUSTRIAL PURPOSES.
2,A WATER SAVING SYSTEM AS CLAIMED IN CLAIM 1, WHEREIN BALL COCK VAI.VES ARE PROVIDED TO CONTROL THE LEVEL OF RAIN WATER STORED IN THE STORAGE TANK. THE TANK BEING ADAPTED TO REVERT TO MAINS WATER SUPPLY DURING
PERIODS OF LOW RAINFALL.
3,A WATER SAVING SYSTEM AS CLAIMED IN CLAIM 1 OR CLAIM 2 WHEREIN A COLLECTION TANK IS PROVIDED TO COLLET RAIN WATER PRIOR TO TRANSFER
TO STORAGE TANK.
4, A WATER SAVING SYSTEM AS CLAIMED IN CLAIM 2 OR CLAM 3 WHEREIN
FILTERS ARE PROVIDED TO CLEAN THE RAIN WATER BEFORE USE.
5, A WATER SAVING SYSTEM AS CLAIMED IN CLAIM 4 WHEREIN A PUMP IS
PROVIDED IF NECESSARY TO TRANSFER RAIN WATER TO THE STORAGE TANK.
,A WATER SAVING SYSTEM SUBSTANTIALLY AS DESCRIBED HEREIN WITH REFERENCE TO FIGURES 1 TO 4 OF THE ACCOMPANYING DRAWINGS.
