In the city of Sana'a, the municipal water supply consists of both public and private water
supplies. In 1993, the public water supply produced around 17.8 × 106 m3 providing 43
per cent of the city's population with a per capita consumption of about 120 1 d-1,
including 35 per cent that was not accounted for. Groundwater from the NWSA wellfields
(Figure XIII.3) is of good quality and meets the World Health Organization (WHO)
drinking water guidelines. Nevertheless, chlorination is usually applied as a safety
measure in the distribution network. Private water supplies, which depend on
unmonitored private boreholes in the city, some of which also draw from the Tawilah,
were estimated to have produced 6.7 × 106 m3 in 1993. Although the private water supply
is supposed to cover 57 per cent of the city's population, the high price of the water is
suspected to reduce the per capita consumption to about 35 l d-1.
