Wastewater management

The sewer systems in Sanaa is over 500 kilometres long. There are two activated sludge water treatment plants in the city: the main one, in Bani al-Harith District, was commissioned in 2000 and has a daily capacity of 50,500m; the second, in al-Hashishiyah, is much smaller with a capacity of 500m and is dedicated to collecting wastewater from tankers. No damage was reported to the Bani al-Harith water treatment plant as of 2018, and it remains in operation, although overloaded and with some equipment in poor condition. The al-Hashishiyah facility has been out of operation since the start of the conflict.

Only 40% of Sanaa's population is connected to wastewater services as of 2018 (down from 45% in 2014), and over half of the population relies on private cesspits for wastewater disposal. The wastewater is then either absorbed into the ground or pumped out by either the city's Wastewater and Sanitation Local Corporation or by private services. Of Sanaa's 35 informal settlements, only two (Madhbah and Bayt Maiyad) are connected to the city's sewer system, while most of the others rely on cesspits. In one, Suq Shamlan, sewage is dumped in an open hole.
