Ashghal's national sewer network assets reached 9,707 km in 2025, up from 2,836 km in 2013. Over the same recent stretch, Qatar's water production barely moved: it stayed between 666 and 691 Mm3 a year from 2019 to 2025. Doha is served by one national water network and one national drainage network, and most of the named projects around the city sit on the drainage side.
Drainage leads the project list
Seven of the eleven major projects tracked around Doha are Ashghal sewer, treated-effluent or flood-drainage works. In June 2026 Ashghal awarded NICC about QAR 378.8m (USD 104m) to finish the trunk sewer from Sheehaniya to the Doha North Sewage Treatment Works, over 1,188 calendar days. On 8 October 2026 it re-awarded eight delayed packages to new contractors, including sewer and treated-effluent lines to Doha North, with the first package due in Q3 2027.
Two schemes awaiting confirmation
The D-Line treated-effluent main and pumping station was expected to be complete by end-2025. Its last confirmed status, reported on 28 July 2025, was under construction, and no completion has been announced. The Al Wakrah and Al Wukair sewage treatment PPP, valued at more than QAR 5.4bn in total cost over 25 years, was expected to complete all works in 2026; its last confirmed construction update dates from 7 January 2025.
Who pays for drainage
Since the January 2021 bills, Ashghal's wastewater disposal charge has added 20% to the monthly KAHRAMAA water bill, so a QAR 300 water bill carries a further QAR 60. Ashghal sells treated effluent at 25 dirham per m3 for general use, on a form dated 13 August 2025.
