Safe Water Network, IndiaDrinking Water Access for Reporting Purposes

Document providing summary of data sources and principles of arriving at the finalpopulation with drinking water access.

1. Source of Population Data

1.1 We establish population of each of the target village from the Ministry of Drinking Water and

Sanitation (MDWS) website http://www.mdws.gov.in/. When we click on the “view habitation details

of your village” link, we are taken to the following website:

http://indiawater.gov.in/imisreports/Reports/Profile/rpt_SearchProfile.aspx?Rep=Y. This process is being followed

since 2009 when we initiated the program.

1.2 We also initiated cross checking the village population data from the Census website

www.censusindia.gov.in. The specific link for finding the village data is

http://www.censusindia.gov.in/Census_Data_2001/Village_Directory/View_data/Village_Profile.aspx. This website

provides us individual village population as per 2001 census as the data of 2011 Census is yet to

be uploaded. This process is being followed since 2013.

1.3 The final check for the addressable households (HH) or population is based on the installed plant

capacity and the available number of hours of power in the village. From our experience, we find

that the water usage per capita per day (LPCD) in peak summer is about 2 LPCD. Hence we

believe that only 1200 HH can be serviced using one plant. However, the average population per

HH varies and we take the local average population per HH as the multiplier for arriving at the total

access population. If there are more than one plant per village, the addressable households will be

divided by the number of plants in the village.

1.4 If there are more than one plants in a village, the total number of households will be divided by the

number of plants existing in the village.

2. Principles of calculating Access

Households

2.1 Average of MDWS and Census households is considered.

2.2 Where Census data is not available, the MDWS data is considered.

2.3 If the number of households are larger than 1200, then we consider 1200 households as

addressable households.

Population per HH

2.4 Average of MDWS and Census population per household is considered.

2.5 Where Census data is not available, the MDWS data is considered.

1.3 Participatory Rural Appraisal (PRA) is also carried out in the villages where the above data seems

incorrect by physical verification during our field visits. This is generally the case when the two

adjacent habitations are merged due to expansion of their natural boundaries. Our field personnel

therefore carry out physical mapping through a PRA exercise which in some cases uses Google

Maps software. The outcome of the PRA mapping exercise is thereafter certified by the Safe Water

Network India Head of Operations. This is only carried out in case the actual population derived

from the MDWS or Census sites are far lower than the claimed population by the local villagers

who are interested in carrying out the program in their village.

1.4 The final check for the addressable households (HH) or population is based on the installed plant

capacity and the available number of hours of power in the village. From our experience, we find

1.5 If there are more than one plants in a village, the total number of households will be divided by the

number of plants existing in the village.

2. Principles of calculating Access

Households

2.6 Average of MDWS and Census households is considered.

2.7 Where Census data is not available, the Average of MDWS and PRA is considered.

2.8 In the absence of Census or PRA data, we consider MDWS households data.

Population per HH

2.9 Average of MDWS and Census population per household is considered.

2.10 Where Census data is not available, the Average of MDWS and PRA is considered.

2.11 In the absence of Census or PRA data, we consider MDWS population data.
