• Natural calamities can't be prevented but the impact of the disaster on life sure can be mitigated to a certain extent by taking quick remedial action. It is seen that the unavailability of potable water after a disaster leads to consumption of water unfit for drinking rendering individuals prone to various water-borne diseases and maybe, even a full-blown pandemic in worst-case scenarios.
• The Adam’s Ale project, when implemented, would be highly beneficial to people in case of such disasters and natural calamities.
• We aim to significantly reduce the post-disaster epidemics due to water-borne diseases through this project.

The personnel from rescue team (referred to here as ‘Tester’) will be carrying ‘Testing Probes’ to check the quality of water in local water sources. If it is found fit for drinking, the location will be saved for the victims to consume water from that.

1. Operator’s side: The testing probe will be able to identify water sources safe for drinking and tag its geolocation.
2. User’s side: Victim’s mobile application will be able to identify the nearest potable water source in online/offline modes and the guide to it.

The project is divided into 4 parts:

• The testing probe will be equipped with a Multi-Sensor Array (MSA) that will be able to measure the temperature, pH, turbidity and Oxidation Reduction Potential (ORP) of the water body and follow the parameters from WHO guidelines to determine whether the water is safe for drinking.
• If yes, it will be communicated to the tester’s phone. Application there will be able to communicate the same to the server using online method.

• The data (geolocations) of the water sources will be stored in a firebase database. The read, write and fetch functions on the firebase database and calculation of distance and nearest water source is done in the cloud.

• The user side application can be used in Online as well as offline modes(Usually, there are connectivity uses after natural calamities).

The SMS Base station receives the GPS coordinates of the user via SMS and sends it to the cloud. Since we are well aware of the fact that the user is offline, we are fetching route directions and sending it back via another SMS.

• As cellular network might be disrupted in case of natural calamities, even the offline way of updating the database might not work. Hence, we have decided to add LoRaWAN feature to the testing probe in later versions of the project. Then, the base station would be able to communicate the same to the server.
• In further versions of the project, we aim to develop the application for Kai OS and other feature phones so that no one is deprived of the basic amenity (bare necessity) - drinking water.
• Backend Modification and implementation of load balancing to make Adam’s Ale available to more number of users at a time.
