BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art. [0003] Monitoring level of water inside water tank positioned in buildings, houses, and other apartments is challenging task, as it is not easy to go on roof and to check level of water. Therefore, there is a need of automatically checking of the water level and filling the tank automatically. Also, tank can be filled only when service provider (i.e. Municipal Corporation) supply water. One or more motors are attached in each building based on consumption to propel supply water to the tanks. However, there are certain timings of supply water, if motor is not turned ON at that time, tanks cannot be filled later, the user have to wait. [0004] Also, there are several areas in which water pressure of central water supply line is very low, therefore supply water is not provided properly in those areas as per the need. Thus, many house owners attach a pump on center water supply to obtain high pressure, and the water supply from the service provider in remote areas is uncertain based on the timings, durations, days, and electricity supply. The continuous water supply is always interrupted as per above-mentioned parameters, due to uncertainties in timings of the scheduled water supply the people are totally dependent and their daily routine works is disturbed. [0005] There are various auto and manual controllers are available in market, but they are only used for water management between the base water storage tank and various overhead tanks. They cannot control water management between center pipeline and overhead tanks because they are not using the sensors and

controlled techniques. They are not providing solution for full automation of water management between central pipeline and household water supplies. [0006] There is a need to overcome above mentioned problems of prior art by bringing a solution that helps in detecting level of water in water tanks of a premises and automatically supply water to the water tanks, even when central supply water is not available.

DETAILED DESCRIPTION
[0030] The figures and description herein are directed to water supply in a premises such as building, offices, and houses. The present invention provides a system to detect water level in water tanks of a premises, and correspondingly filling water in the water tanks either from central overhead tank or underground auxiliary water tank.
[0031] As illustrated in FIG. 1, the proposed system (100) (also referred to as system 100, herein) pertains to controlling supply of water in a premises. The system (100) can include one or more overhead tanks (102-1, 102-2) (individually referred as overhead tank 102) placed in a neighborhood or on the rooftop of the premises (also referred as building, hereinafter). Each of the overhead tank (102) can include a first sensor (106), and the first sensor (106) can be configured to detect level of water in the associated overhead tank (102). In addition, an auxiliary water tank (104) can be positioned underground or somewhere else in the building to receive and store water. Also, auxiliary water tank (104) can be a well. Each of the overhead tanks (102-1, 102-2) and auxiliary water tank (104) can be configured to receive water from a central water reservoir (110). [0032] In an embodiment, the first sensor (106) can be selected from a group consisting of but not limited to water hydrostatic pressure level sensor, water level sensor, and level sensor.
[0033] In an embodiment, a set of tubes (112) can be configured to supply water from the central water reservoir (110) to each of the overhead tanks (102-1, 102-2). In addition the set of tubes (112) can be configured to supply water from the central water reservoir (110) to the auxiliary water tank (104). Each of the overhead tanks (102-1, 102-2) can be configured to receive water from the central water reservoir (110) and the auxiliary water tank (104). For example, central water reservoir (110) can supply water at pre-defined times in a day such as at 7 AM to 10AM in morning, 1 PM to 3 PM in noon, and 7 PM to 9 PM in the evening. When level of water is down in any of the overhead tanks (102) or they are empty, and supply water is not coming (for example at 10 PM in night), then

the water from the auxiliary water tank (104) can be supplied to the associated overhead tank (102).
[0034] In an embodiment, a second sensor (108) can be deployed to sense flow of water from the central water reservoir (110). The second sensor (108) can be selected from a group consisting of but not limited to pressure sensor, pressure gauge, flow sensor, and flow meter. Moreover, the second sensor (108) can be deployed to the at least one tube of the set of tubes (112) that can be connected to supply water from the central water reservoir (110) to the overhead tank(s) (102) and the auxiliary water tank (104).
[0035] In an embodiment, the system (100) can include a motor (114) (also referred as pump (114), hereinafter) that can be configured to propel water from the central water reservoir (110) and the auxiliary water tank (104). The motor (114) can facilitate movement of the water from a first predetermined height to a second predetermined height, where the first predetermined height can be ground and the second predetermined height can be height of the overhead tank(s) (102). The controller (118) can be configured to execute the ON command to supply electricity to turn ON the motor (114), and OFF command to supply electricity to turn OFF the motor (114).
[0036] In an embodiment, the motor (114) can be automatically turned ON, when there is a need of filling the overhead tank (102) and the motor (114) can be turned OFF automatically when the overhead tank (102) is full to prevent overflow, also increase life of the motor (114). Moreover, the motor (114) can be turn on/off manually also from a switch by the user.
[0037] In an embodiment, the motor (114) can be configured to propel water upon actuation of the motor (114) only. In an exemplary embodiment, there are many type of motors available to replenish (refill) water in the overhead tank(s) (102). Electric power operated motor is generally the preferred choice. An impeller operated by an electric motor lifts the water up to the required height. In the absence of the electric supply, water pumps driven by Internal Combustion engine, steam engine, solar power, storage battery, etc. can be used. Depending on the height of the overhead tanks (102) from the source of the water, submersible

pump, vacuum pump, or jet pump can be used. In case of vacuum pumps, the
water can be lifted due to continuous vacuum created by the rotating movement of
impeller that causes the displacement of air. In case of submersible pumps, the
pump can be immersed in the water and the water can be directly pushed up
thereby lifting the water through the pipe to the desired height to fill the overhead
tank(s) (102).
[0038] In an embodiment, a pair of valves (116-1, 116-2) (collectively
referred as valves (116), and individually referred as valve (116)) can be coupled
to the set of tubes (112) to control flow of the water. Upon supplying water from
the central water reservoir (110) to the overhead tank(s) (102) and the auxiliary
water tank (104), the valve (116-1) can be shut off to prevent flowing of water
from the auxiliary water tank (104) to the overhead tank(s) (102). Similarly, upon
supplying water from the auxiliary water tank (104) to the overhead tank(s) (102),
the valve (116-2) can be shut off to prevent flow of water from the central water
reservoir (110) to the overhead tank(s) (102).
[0039] In an embodiment, the auxiliary water tank (104) can include an
auxiliary inlet (122) and an auxiliary outlet (124). The auxiliary inlet (122) can be
configured to receive water from the central water reservoir (110), and the
auxiliary outlet (124) can be configured to supply water to the overhead tank(s)
(102).
[0040] In an embodiment, the pair of valves (116) can be solenoid valves but
not limited to likes, other type of valves such as ON-OFF valve, open-close valve
can also be used based on the requirements.
[0041] In an embodiment, the system (100) can include a means for
connecting the first sensor (106) and the second sensor (108) to the controller
(118), and the means can be wireless such as Wireless Fidelity (Wi-Fi) module,
Bluetooth module, Li-Fi module, optical fiber, Wireless Local Area Network
(WLAN), and ZigBee module, but not limited to the likes.
[0042] In an embodiment, the system (100) can include a power source (126)
operatively coupled with the first sensor (106), the second sensor (108), the motor
(114) and the controller (118). The power source (126) can be configured to

supply electric power to the system (100). The power source (126) can include any or a combination of battery, inverter, generator, electric line, cell, and the likes.
[0043] Referring to FIG. 2, functional components of a controller (118) are disclosed. The controller (118) can include one or more processor(s) (202). The one or more processor(s) (202) can be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, logic circuitries, and/or any devices that manipulate data based on operational instructions. Among other capabilities, the one or more processor(s) (202) are configured to fetch and execute computer-readable instructions stored in a memory (204) of the controller (118). The memory (204) can store one or more computer-readable instructions or routines, which may be fetched and executed to create or share the data units over a network service. The memory (204) can include any non-transitory storage device including, for example, volatile memory such as RAM, or non-volatile memory such as EPROM, flash memory, and the like.
[0044] In an embodiment, the controller (118) can also include an interface(s) (206). The interface(s) (206) may include a variety of interfaces, for example, interfaces for data input and output devices, referred to as I/O devices, storage devices, and the like. The interface(s) (206) may facilitate communication of the controller (118) with various devices coupled to the controller (118). The interface(s) (206) may also provide a communication pathway for one or more components of controller (118).
[0045] In an embodiment, a processing engine(s) (208) can be implemented as a combination of hardware and programming (for example, programmable instructions) to implement one or more functionalities of the processing engine(s) (208). In examples described herein, such combinations of hardware and programming may be implemented in several different ways. For example, the programming for the processing engine(s) (208) may be processor executable instructions stored on a non-transitory machine-readable storage medium and the hardware for the processing engine(s) (208) may include a processing resource

(for example, one or more processors), to execute such instructions. In the present examples, the machine-readable storage medium may store instructions that, when executed by the processing resource, implement the processing engine(s) (208). In such examples, the controller (118) can include the machine-readable storage medium storing the instructions and the processing resource to execute the instructions, or the machine-readable storage medium may be separate but accessible to controller (118) and the processing resource. In other examples, the processing engine(s) (208) may be implemented by electronic circuitry. A database (210) can include data that is either stored or generated as a result of functionalities implemented by any of the components of the processing engine(s) (208).
[0046] In an embodiment, the processing engine(s) (208) can include an extraction unit (212), a comparison unit (214), a signal generation unit (216), and other unit (s) (218). The other unit(s) (218) can implement functionalities that supplement applications or functions performed by the system (100) or the processing engine(s) (208).
[0047] The database (210) can include data that is either stored or generated as a result of functionalities implemented by any of the components of the processing engine(s) (208).
[0048] It would be appreciated that units being described are only exemplary units and any other unit or sub-unit may be included as part of the system (100). These units too may be merged or divided into super- units or sub-units as may be configured.
[0049] As illustrated in FIG. 2, the controller (118) can be configured to receive a first set of signals from a first sensor (106) and a second set of signals from a second sensor (108) in electrical form. In an embodiment, the controller (118) can be configured to extract level of water from the first set of signals, and flow rate of the water supplying from the central water reservoir (110) with help of the extraction unit (212). The controller (118) can be configured to compare the level of the water with a dataset with help of the comparison unit (214) where the dataset can includes predetermined water level limit.

[0050] In an embodiment, upon receiving the level of water beyond the predetermined limit, the controller (118) can check flow rate of the water of the central water reservoir (110). When the flow rate is below the predetermined flow rate (i.e., central water reservoir (110) is not supplying water at that time as this is well known that water is being supplied at pre-defined times only), the signal generation unit (216) can generate actuation signal to actuate a motor (114) by providing electricity to the motor (114).
[0051] In an embodiment, the signal generation unit (216) can generate a first set of control signals which can be transmitted to the first valve (116-1) to open it, that facilitates in propelling water from the auxiliary water tank (104) to the overhead tank(s) (102), simultaneously a second set of control signals can be transmitted to the second valve (116-2) to close it. Similarly, when the water can be supplied from the central water reservoir (110), the signal generation unit (216) can generate the first set of control signals which can be transmitted to the second valve (116-2) to open it, and simultaneously, the second set of control signals can be transmitted to the first valve (116-1) to close it. Moreover, when the overhead tank(s) (102) found full, the controller can cut power supply of the motor (114) automatically.
[0052] FIG. 3 illustrates an exemplary flowchart on working of the proposed water supply controlling system (100). At step (302), the flowchart include a step of sensing level of water in an overhead tank (102). The sensed level of water can be compared with predetermined limits and the comparison of the sensed water level can be done with help of a controller (118). Upon detection of a need of replenish water in the overhead tank (102) (i.e. YES in step (302)) flow rate of water flowing from a central water reservoir (110) can be sensed and compared with the predetermined limits as shown in step (304). When the flow rate condition found met (i.e. YES in step (304)), a second valve (116-2) can be opened at step (306), and a motor (114) can be actuated at step (308). At step (310), the water can be propelled from the central water reservoir (110), and at step (312) the water can be replenished into the overhead tank (102),

simultaneously, the water can be replenished into the auxiliary water tank (104) at
shown in step (314).
[0053] In an embodiment, when the determination is NO in step (304), the
process of step (316) can be performed i.e. a first valve (116-1) can be opened,
and the motor (114) can be actuated as shown in step (318) to propel water from
an auxiliary water tank (104) as shown in step (318) to the overhead tank (102) as
shown in step (320). Further the process is returned back to the main routine to
check level of water in the overhead tank (102) again, and automatically the motor
(114) can be turned OFF.
[0054] In an embodiment, the system (100) can be configured to prevent the
motor (114) from getting damaged by controlling various operations such as dry
run, over voltage/voltage fluctuations, overcurrent conditions. Also, check
conditions for example, low voltage, high voltage, load, trip time, and
correspondingly control the motor (114)
[0055] In an embodiment, the system (100) can be password protected that
allows only authorized user to control the system (100), such as for storing
instructions, and values, timing in the memory of the controller (118).
[0056] It should be understood that the embodiments disclosed herein are
illustrative and non-restrictive in every respect. It is therefore intended that the
scope of the present invention is defined by claims, not only by the embodiments
described above, and encompasses all modifications and variations equivalent in
meaning and scope to the claims.
