Water Quantity

% of households with at least 15 litres of safe water for drinking, cooking and personal hygiene per person per day

The indicator assesses the proportion of households whose members collect a sufficient quantity of safe water for meeting their needs (the amount of 15 litres is based on the Sphere Standards).

Collect the following data by conducting individual interviews with a representative sample of the household members responsible for water collection:

 

RECOMMENDED SURVEY QUESTIONS (Q) AND POSSIBLE ANSWERS (A)

(ask the following question only if you have not asked it in the previous sections of the questionnaire)

Q1: How many children and adults currently live in your household? 

A1: ............ specify the number of children 

 

Q2: What container do you most commonly use for collecting or storing water?

A2 - specify the container's volume: ............ liters

  

Q3: How many of such water containers do your household members use per one day for drinking and cooking?

A3: ............ specify the number of containers 

 

(ask the following question only if you have not asked it earlier)

       

Q4: During this season, where do your household members collect water for drinking and cooking?

A4: _

1) tube well or borehole 

2) protected shallow well 

3) protected rainwater collection system

4) piped water/public tap 

5) protected spring 

6) packaged or delivered water

7) emergency water treatment systems

8) surface water source (river, stream, pond, puddles, unprotected spring) 

9) unprotected/ open shallow well

10) cart with small tank/drum

11) tanker-truck

12) other: ................................

NOTE: Only options 1 – 7 count as “safe water sources”

 

Q5: How many of such water containers do your household members use per one day for personal hygiene?

A5: ............ specify the number of containers 

 

To calculate the indicator's value, take the following steps:

   1) count the number of households that are able to access at least 15 liters of water per person per day and their drinking water comes from safe water source(s)

   2) divide this number by the total number of respondents

   3) multiply the result by 100 to convert it to a percentage

1) Read Sphere's Water supply standard 1: Access and water quantity for a detailed breakdown of the minimum water requirements (per person) for the three main purposes - drinking, cooking and personal hygiene. 

 

2) According to the Sphere Standards, “safe water” is defined as meeting the following two requirements:

• there are no faecal coliforms per 100ml at the point of delivery; and

• there is a free chlorine residual at the tap of 0.5mg per litre, and turbidity is below 5 NTU for piped supplies, trucked supplies, and any water provided when there is a risk of a diarrheal epidemic

...

3) Ensure that the data collectors count all people who currently live in the household, including people who are not regular household members, such as internally displaced persons.  

 

4) Ensure that the data collectors are familiar with the main types of water containers the respondents use and know their volume (number of liters).

  

5) ECHO's list of its Key Result Indicators (KRI) uses a different water supply indicator: "number of people having access to sufficient and safe water for domestic use". ECHO's guidance on the use of this indicator is available below. 

 

6) BHA phrases the indicator differently, as "estimated safe water supplied per beneficiary in liters/person/day" and "average liters/person/day collected from all sources for drinking, cooking, and hygiene". Further information is provided in BHA's guidance Emergency application guidelines below. 

 

7) For emergency livestock water needs, refer to Livestock Emergency Guidelines and Standards.
