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] Water is a life giving element as water supports all forms of life. Judicious utilization of water is a matter of concern as water is wasted in public places, offices and even in households. Many public places including houses have an unlimited supply and all the water, whether dirty, soap laden, and used for different purposed can go in drain and become drain water. Even in Hospitals, water can be wasted, whether used in surgery, in washrooms or during normal hand washing. The water in hospitals go down in the drain. Limited supply of fit water can make even more important to conserve and save the water. Therefore, there should be a check-in place for water to reuse the water for other activities and the water does not goes into the drain. Whopping 60 million litres (MLD) (approximately) water daily on average is wasted, as per a survey. This makes conservation of water, a need of the hour. A large percentage of drain water can be reused in other activities like watering the plants, washing cars and flushing. [0004] Existing solutions can include a method for recycling wastewater. A method for recycling waste water for smart living. The method includes detecting physical indicators of waste water and judging whether it meets the recycling standard. If it meets the recycling standard, enter the purifier to purify the waste water, and then enter the recycling pipeline. Physical indicators of the detected wastewater include the pH value and the value of soluble matter. Detecting the physical indicators of wastewater to determine whether it meets the recycling standard; if it meets the recycling standard, automatically opening the recycling

pipeline valve and entering the recycling pipeline. The waste water flows into the sewage tank through the sewage pipe, detecting the physical indicators of the waste water, and judging whether it meets the recycling standard. Another solution can include an automatic analyzer where the analyzer is configured to classify the water based on pollution level present inside the water. However, the existing solutions lack in-pipe drain monitoring systems, which can be installed beneath the wash basins or sinks in a household, hospitals, kitchens/ industry etc. Also, method to determine threshold level for impurities that can clog and choke the sink, and other pipes are not disclosed.
[0005] There is a need to overcome above mentioned problems of prior art by bringing a solution that facilitates in analyzing impurity and pollution level of drain water and can segregate the drain water accordingly. Further, the solution can notify user for impurity level and determining threshold values that can clog or block the pipes and sinks. The solution can include real time monitoring of drain water stored in a tank and requirement for cleaning and purification. Also, the solution can focus on in-pipe drain monitoring systems, which can be installed beneath the wash basins or sinks in a household, hospitals, kitchens/ industry etc.

[0056] FIG. 2 illustrates an exemplary view of the proposed drain water
monitoring and purifying system, in accordance with an embodiment of the
present disclosure.
[0057] FIG. 3 illustrates an exemplary view of block diagram of working
proposed drain water monitoring and purifying system, in accordance with an
embodiment of the present disclosure.
[0058] As illustrated in FIG. 2 and FIG. 3, water flows down from drainpipe
can be stored in a tank (202) which can be called a Main Tank of 1.5 Litre
(approx.), but not limited to quantity. The system (100) can a first set of sensors

and transmit values to NodeMCU which can be an Internet of Things (IoT)
device.
[0059] Information collected from the first set of sensors (102) and the second
set of sensors (104) can be stored over a cloud or a sever. Calculated purity level
of water by the controller (106) can also be stored on the cloud which can

eventually help in getting deeper insights into the information collected at any particular time frame. Along with this, a GPS module (110) can also be placed to detect location of the main tank (202) and a set of containers (204) in case of any malfunction.
[0060] In an embodiment, the NodeMCU can be configured to receive and record readings and information received from the first set of sensors (102), and the second set of sensors (104). The NodeMCU can be configured to detect level of contamination of the drain water and then initial segregation of the drain water starts. The NodeMCU can check purity level and then sends a set of actuation signal to a set of motors attached to the main tank (202) which opens t way to the set of containers (204) according to contamination level of the drian water. [0061] In an embodiment, tested water can be divided into three categories, i.e., clean water, contaminated water, and turbid water. First container (204-1) from the set of containers (204) can be of contaminated water that can go directly to water treatment plant through an already conventional sewage system. In another embodiment, a second container (204-2) can be of clean water, where the clean water can be reused as the clean water has least amount of impurities. The clean water can be stored in a tank, where the tank can include a third set of sensors like water flow sensor and water sensor.

In yet another illustrative embodiment, the GPS unit (110) can help in detecting location of the system (100) in case of any malfunction.
[0064] In an illustrative embodiment, the first set of sensors (102), and the second set of sensors (104) can be configured to determine quality of the drain water. In another illustrative embodiment, a pH sensor can be used ot determine pH of the drain water. A pH scale can be used to measure acidity and basicity of a liquid, where readings can range from 1-14 where 1 shows most acidic liquid and 14 shows most basic liquid. pH measurement can be used to segregate the drain water and use for further propose according to the pH level. [0065] In an illustrative embodiment, total dissolved solids (TDS) sensor can be configured to determine number of solids dissolved in a pre-determined quantity of water in ppm (parts per million). For example - TDS values of different types of water: Pure water: 80-150, Tap water: 250-350, Groundwater: 500-1000, Seawater: around 30000, but not limited to the given values. According to level, drain water is segregated and used for further use. In another illustrative embodiment, Gravity: Analog Dissolved Oxygen Sensor can be used to measure dissolved oxygen in water, to reflect water quality.
[0066] In an illustrative embodiment, Turbidity sensors can measure amount of light that can be scattered by suspended solids in water. As amount of total suspended solids (TSS) in water increases, water's turbidity level (and cloudiness or haziness) also increases. In another illustrative embodiment, Waterproof Ultrasonic Obstacle Sensor can provide information on objects between distance range of the main tank (202), so if there is any other substance or thick liquid like ketchup, blood which comes along with the water can be detected and the water can be segregated.
[0067] In an illustrative embodiment, water sensor can detect water level inside the set of containers (204) and can gives signal to the NodeMCU which with help of the cloud can notify Admin over SMS/Email and Push

Notification(in case using App). In another illustrative embodiment, water flow sensor can calculate amount of water flowing through the second container (204-2), and the third container (204-3) and can send to the NodeMCU. Further, NodeMCU can stores all the information on the cloud. The NodeMCU can helps in collecting the information and analyzing quantity of water to be saved daily. The information can also be used to track down industries and individual bodies that exploit life-sustaining element water.
[0068] In an illustrative embodiment, the drain water monitoring system (100) can help in monitoring drain water on basis of impurities present inside the drain water. The drain water monitoring system (100) can include various types of sensors such as Ph sensor, turbidity sensor, waterproof ultrasonic obstacle sensor, Gravity: analog dissolved oxygen sensor and TDS sensor to evaluate water purity and give values to the Node MCU (an IOT device). The information collected from the sensors can be stored over the cloud. Hence, the calculated purity level of water can also stored on the cloud which can eventually help in getting deeper insights into the information collected at any particular time frame. The GPS module (110) can also be provided to detect the location of the system (102) in case of any malfunction.
[0069] In an illustrative embodiment, the drain water can be classified or segregated into three different categories including contaminated water, clean water and turbid water. The segregated water can be treated or disposed on basis of impurities present in the drain water. Contaminated water goes to the water treatment plant through conventional sewage system. Turbid water can be cleaned through natural filters such as charcoal, alum and filter papers. Clean water can be directly used for different purposes.
[0070] As used herein, and unless the context dictates otherwise, the term "coupled to" is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms "coupled to" and "coupled with" are used synonymously. Within the context of this document terms "coupled to" and "coupled with" are also used

euphemistically to mean "communicatively coupled with" over a network, where two or more devices are able to exchange data with each other over the network, possibly via one or more intermediary device.
[0071] It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context.

[0072] While the foregoing describes various embodiments of the invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof. The scope of the invention is determined by the claims that follow. The invention is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the invention when combined with information and knowledge available to the person having ordinary skill in the art.
