Water Services:

This is the egov application, which helps and gives flexibility to municipal and citizen to handle the water service like apply for water connection, search water connection. The application will go on different stages that state can verify by given roles, If that role can take the action then the application will go to the next state. Based on the state, citizen will get notification (SMS and in-app ). Citizens also can pay for application fees or employees can collect the fee for the application.

The setup of the Application is as follows

Requirements:

• Knowledge of Java/J2EE(preferably Java 8 version)

• Knowledge of Spring Boot and spring-boot microservices.

• Knowledge of Git or any version control system.

• Knowledge of RESTful Web services.

• Knowledge of the Lombok library will helpful.

• knowledge of eGov-mdms service, eGov-persister, eGov-idgen, eGov-sms, eGov-email,eGov-user, eGov-localization, eGov-workflow-service will be helpful.

Functionality:

1. Apply for water connection.

2. Searching for water connections.

3. Apply for Property creation.

4. Can take different action based on state (Workflow)

5. Notification based on the application state.

Setup and usage:

The Application is present among the municipal services group of applications available in the eGov-services git repository.  The spring boot application needs the Lombok* extension added in your IDE to load it. Once the application is up and running API requests can be posted to the URL and ids can be generated. 

• in case of IntelliJ, the plugin can be installed directly, for eclipse the Lombok jar location has to be added in eclipse.ini file in this format  javaagent:lombok.jar

Indexer config for water-service:

• The indexer provides the facility for indexing the data to elastic search.

Setup:

1. Write the configuration for water service. The structure of the config file is explained later in the same doc.

2. Provide the absolute path of the checked-in file to DevOps, to add it to the file-read path of egov-indexer. The file will be added to the egov-indexer's environment manifest file for it to be read at the start-up of the application.

3. Put indexer config file to the config repo under egov-indexer folder.( )

4. Run the egov-indexer app, Since it is a consumer, it starts listening to the configured topics and indexes the data.

config Keys:

      iv) fieldMapping: Contains a list of configurations. Each configuration contains keys to identify the field of the input JSON that has to be mapped to the fields of the index json which is mentioned in the key 'indexMapping' in the config. Has the following keys:

1. inJsonPath: JSONPath of the field from the input.

2. outJsonPath: JSONPath of the field of the index json.

        v) externalUriMapping: Contains a list of configurations. Each configuration contains keys to identify the field of the input JSON that are to be enriched using APIs from the external services. The confiugration for those APIs also is a part of this. Uses the following keys:

1. path: URI of the API to be used. (it should be POST/_search API.)

2. queryParam: Configruation of the query params to be used for the API call. It is a comma seperated key-value pair, where key is the parameter name as per the API contract and value is the JSONPath of the field to be equated against this paramter.

3. apiRequest: Request Body of the API. (Since we only use _search APIs, it should be only RequestInfo.)

4. uriResponseMapping: Contains a list of configuration. Each configuration contains two keys: One is a JSONPath to identify the field from response, Second is also a JSONPath to map the response field to a field of the index json mentioned in the key 'indexMapping'.

Modify connection:

After connection activation or legacy connection, we can edit the connection. This process based on defined workflow. Any action is based on defined roles on the action level. For edit connection, we need to upload some supporting documents and mandatory info.

Workflow config for edit connection:

Notification :

Notification will be sent to the property owners and connection holders based on different application states.

Capturing connection holders :

We can add connection holders to the water connection which will be the owner of the connection. We can fill the connection holders' details or we can just make the property owner to the connection holder.

The connection holder will get notification based on a different state of the application. We are pushing the data of the connection holders in the user service too.

Multiple Road Type Support
We can add road cutting details of multiple roads to the water connection. For each road which goes under cutting process we have to fill their road type details and road cutting area.
Based on this information, application one time fee estimate is calculated.

Water Calculator Service - Technical Document

This application is used for creating meter reading, searching meter reading, updating existing meter reading, calculation of water charge, demand generation, SMS & email notification to ULB officials on-demand generation and estimation of water charge(one-time cost) which involves cost like road-cutting charge, form fee, scrutiny fee, etc.

Billing Slabs:

Criteria :

1. connection type

2. building type

3. calculation attribute

4. property usage type

The combination of the above can be used to define the billing slab. Billing Slab is defined in mdms under ws-services-calculation folder with the WCBillingSlab. The following is the sample slab.

If all criteria will match for that water connection this slab will use for calculation.

Estimation:

For application one-time fee, the estimation will return all the related tax head based on criteria. For estimation, all configuration is present in ws-services-calculation.

1. FeeSlab.json

2. PlotSizeSlab.json

3. RoadType.json

All the above master configuration is used for estimation.

Following are the exemptions and taxes that are calculated:

• Form fee

• Scrutiny fee

• Meter charge (For metered connection)

• Other charges

• Road cutting charges

• One time fee

• Security charges

• Tax and cess

Water Charge and Tax:

Water charge is based on billing slab, for water application charge will be based on slab and tax based on master configuration.

Interest:

Below is a sample of master data JSON for interest :

Penalty:

Below is a sample of master data JSON for penalty :

Round Off:

If the fraction is greater than equal to 0.5 the number is round up else it’s round down. eg: 100.4 will be rounded to 100 while 100.6 will be rounded to 101.

Adding Adhoc penalty or rebate:

The only employee can apply for a penalty or rebate for an existing connection. As an employee, I can update or add the penalty and rebate of a connection. This applied penalty or rebate will be added or updated in existing demand as tax heads. For configuration, we have to add the tax head in TaxHeadMaster.json file.

Demand Generation:

Once water is sent to calculator it’s tax estimates are calculated. Using this tax head estimates demand details are created. For every tax head, estimate demand generates function will create a corresponding demand detail.

Whenever _calculate API is called demand is first searched based on the connection no or application no and the demand from and to period. If demand already exists the same demand is updated else new demand is generated with consumer code as connection no or application no and demand from and to a period equal to financial year start and end period.

In case of the update if the tax head estimates change, the difference in amount for that tax head is added as new demand detail. For example, if the initial demand has one demand detail with WATER_CHARGE equal to 120

After updating if the WATER_CHARGE increases to 150 we add one more demand detail to account for the increased amount. The demand detail will be updated to:

RoundOff is bill based i.e every time bill is generated round off is adjusted so that payable amount is the whole number. Individual WS_ROUNDOFF in demand detail can be greater than 0.5 but the sum of all WS_ROUNDOFF will always be less than 0.5.

Employee UI Guide:

SEARCH APPLICATION / CONNECTION

• Once an Application is created (INITIATED state in Workflow), the application number can be used to search the application. There are several other criteria’s that can be used to search the application.

APPLY FOR NEW WATER AND SEWERAGE CONNECTION

• All the application once INITIATED can have can have until CONNECTION ACTIVATION can have multiple actions buttons. An with selected roles can forward the application with a specific action to the next stage or can make corrections to it using EDIT.

A water application has been INITIATED (The First Stage in Workflow)

• All the applications that has been created once can be submitted (SUBMIT_APPLICATION state in Workflow), by either searching them in using their application number or employee can continue to the next stages and add all the fields required and they will be able to submit the application. Once an application is submitted, they will be redirected to a screen depicted in the below image.

A water application has been SUBMIT_APPLICATION (The Submit Application in Workflow)

Here they will get an option to Download and Print the application, which they have just submitted. An employee can create both Water and Sewerage application at once.

VIEW APPLICATION & CONNECTION DETAILS

• Here an Employee can edit the application, VERIFY AND FORWARD the application to the next stages, REJECT, SEND BACK TO CITIZEN who has applied for this connection. These actions that are seen in the below image, appear only for employees having a specific role which allows the employee to take the below actions.

• From the options provided in the above image, if the employee clicks on EDIT, it will be redirected to the apply screen where the employee will find the details of the application when it was last updated. The employee can click other option as well. It can also click on one of these options after editing the application and then it can do whatever that the employee deems right for the application.

Note: The employee will only get these options if it is authorized to take any of such actions provided in the above image.

• On successful completion of any of the above processes, the employee will be redirected to the below screen. The messages may change based on the actions clicked. Here the action that I have taken is VERIFY_AND_FORWARD. It can be any of the action provided in the above image.

• On successful completion of all the states triggered from the actions taken, the employee will reach to the action as PAY. On click of Pay, the employee will be redirected to the below screen. Here the employee can generate receipt of the amount collected from citizen. Employees will be able to see the PAY option, if they are authorized to Collect Payment from citizen.

• Once the payment is collected, the employee will be redirected to the below screen. Here employee can download and print receipt.

• Once payment has been accepted and the receipt has been generated, the employee can go to search and search the application based on application number. The employee will find the application in Pending Connection Activation state, similar to what is show in the image below. If the employee is authorized to activate the connection, it can activate the connection.

• After the connection has been activated, employee can go to the search and search the connection based on connection number, as shown in the image below.

• After getting the search result as in the above image for the activate connection, the employee can see the details of the connection (Water or Sewerage) after clicking on the connection number in the Consumer No. column. The connection details looks like below, where the employee can find all the details related to the connection created.

Employee can also download and print the connection details if required.
