Water supply

The water supply system is connected to most districts in the city. Basically, most of the poor households have access to the system. However, access to the water supply system is different between the central and peri-urban districts. In the peri-urban districts in this study, 73.1 per cent of the poor households can access the water supply. The others are using safe water taken from a well or purchase it from a water supply service, especially in some distant districts, such as Cu Chi and Can Gio. In the central districts, 88.8 per cent of households are accessing safe water and 10 per cent are using well water (table 8).

Sanitation and environment

The drainage system in the central districts seems more complete than in the peri-urban areas. The proportion of poor households in the central districts connected to the domestic drainage system is high, at 89.2 per cent, while in peri-urban districts, only 60.9 per cent of the poor households is connected to the system. The rest directly discharge their wastewater into a canal, pond or surrounding grounds. In addition, poor households suffer from flooding, which has increased around the city recently. About 18.9 per cent of the poor households live in a tide-flooded area, and 34.5 per cent live in a rain-flooded area; 13.4 per cent get flooded due to rain combined with high tides. This phenomenon takes place more frequently in the peri-urban districts than in the central districts.

Although the peri-urban areas have more open spaces, the drainage capacity is slower than in the central districts. This is partly because the sewers in these districts have not been fully completed. Some poor households in the study report being flooded for three to four days and that they must pump the water out of their house. Several of the houses are located on lowland or the foundation is lower than the road surface and neighbouring houses. As a result, when it rains, their house floods, and the water remains stagnant while slowly draining out. In these areas, the studied households report that the water takes 11-13 hours to drain, but in the central districts, it takes only three to six hours (figure 4).
