This detailed descriptive study used a multi-disciplinary approach bridging anthropology and entomology. A multiple case study design included research in six study areas, defined as blocks. The water supply is irregular in households from both under-privileged and privileged blocks. In under-privileged households where the water supply is irregular, the frequent use of water containers such as water tanks, cisterns, barrels and pots, creates environmental conditions with a greater number of breeding areas of Aedes aegypti. In the more privileged blocks, some households choose to avoid irregularity of water supply by having their own well and pump systems.
