Incremental List of Parameters

The following is an incremental list of the parameters we plan to track as part of the water index. We shall continue to add parameters until we finalise a stable index.

Request Praja members to review this list, focusing on
* Any broad category that has not been covered.
* Any parameter that has been left out.

To add to the list,

edit this wiki page and enter your suggested parameter(s) under the sixth category (Additonal Parameters). Please enter clear and concise parameters/descriptions. Rap on the knuckles for vagueness. :)

The first five categories form the initial list. Additonal parameters suggested by Praja members form the 6th category:

1. Pipe Water

    a. Hours of Supply

    b. Coverage - Percentage of households having a bwssb connection.

    c. Unaccounted for Water- Calculated by measuring the amount of water that BWSSB bills to the amount of water that it supplies.

    d. Slum Coverage - Percentage coverage in slums. BWSSB mandates that every household in a slum must be given a water connection.

    e. Pressure -  The normal pressure of pipeline supply should be upto 3 meters from ground level. i.e Water should be able to reach an overhead tank on the first floor without any pumping by the house owner.

    f. Residual Chlorine

    g. Other Quality parameters as outlined in BIS-10500
 

2. Ground Water

    a. Number of borewells

    b. Depth of borewell

    c. Depth to which the borewell is dug

    d. Depth of Water table

    e. Quality as prescribed in BIS-10500

3. Surface Water

    a. Number of tanks/lakes

    b. Storage capacity

    c. Water Level

    d. Number of tanks under repair by LDA and other agencies; status of work

    e. Presence/Absence of Wildlife - Whether people can spot wildlife around the lake.

    f. Hyacinth-

        i. Presence of hyacinth

        ii. Percentage of lake covered with Hyacinth.
 

4. Sewage

    a. Coverage

    b. Collection Ratio

    c. Capacity of Treatment Plant

    d. Revenues Generated

    e. Personal/Community sewage treatment facility
 

5. Rain Water Harvesting

    a. Number of structures Targetted by BWSSB/ Number Done

    b. Storage/RWH Installation

    c. Ground water recharge/RWH Installation

6. Additional Parameters (added by Praja members)

    a. Infiltration v/s runoff

    b. Sources for water

    c. Water recycling (quality, supply, cost, etc)

    d. Cost/subsidy

    e. Per capita std. requirement / demand vs. availability

    f. On lakes: no. of treatment plants, recovery of cost from surrounding establishments / apartments / homes / industries. again, recycling data

    g. financial viability of BWSSB as part of the index. Key questions would be (1) Are the operational expenses fully covered by revenue, what is the status of the infrastructure - are there huge upcoming capex requirements
