Evidence from South Africa”

Our education
campaign used five Information Brochures. These were handed out to treatment
households by Odi Water employees during education visits that lasted 30-60
minutes. The brochures were translated to the local language (Setswana).
Brochure 1: How to read your
water bill, Brochure 2: How to detect and
fix a water leak, Brochure
3: Tips on saving water indoors, Brochure 4: Tips on saving water
outdoors,
Brochure 5: How to read your
water meter, Baseline survey questionnaire

Interviewer Training
Field workers attended a full day
workshop in March 2012 where they familiarized themselves with the purpose of
the project and the questionnaire. We went through all questions in the questionnaire
and made sure everyone understood the information to be collected and how it
should be recorded. The workshop also included role-playing a household visit
to fine-tune the interview process. We wanted to make sure that household
visits would be as uniform as possible.
Interviewers were young people in their
early 20s. Most of them live in the survey area, and all of them have extensive
experience conducting household visits in this type of setting.
GPS coordinates were collected for the
location of each household. Households’ location relative to each-other is
important to assess any spillover effects from the education intervention.

survey
Typical housing unit and infrastructure
in the sample
Typical properties in the area are
relatively small, the average household size is 4.3 persons. Many housing units
are uniform single-family buildings provided by the government with limited
modifications made by the residents. Thus, living conditions are fairly similar
within our sample.
Each participating household has
water-using sanitation and tap(s) inside the house or outside on the property.
Consumption is metered individually by a meter located on the property and
easily accessible to the household.

Training of the
educational officers
Education officers
delivering the education program were trained by us specifically for this
project. They are employed by Odi Water and regularly make household visits in
our area of study.
The training involved role-playing a
household visit.
During the education program, education
officers were supervised by Odi Water’s marketing department.
Household visits
The education officers visited the households to
give them the education brochures. They explained the contents of each,
emphasizing a list of specific items (for example, how the dial on the water
meter should be read).
