(MENAFN- Gulf Times) Infrastructural works across Qatar, notably in Doha and its immediate surrounds, have received a major fillip with the Public Works Authority (Ashghal) on Sunday awarding 11 contracts worth QR6.58bn.
Nearly 83% of the contracts awarded went to either Qatari-owned companies or their joint ventures.
The major works to be undertaken in coming weeks include those to be implemented as part of the Inner Doha Re-sewerage Implementation Strategy (Idris). They are aimed at building and improving vital drainage infrastructure for the country's southern region.
The QR10.9bn Idris programme, whose works started in 2012, is expected to be completed in 2019. The scheme includes a major deep tunnel sewer network and advanced sewage treatment works.
At the signing on Sunday, three contracts were awarded as part of the Idris, which together were worth nearly QR3.22bn. The work on the main trunk sewer of the Idris will start in the third quarter of 2015 and expected to be completed towards the end of 2019.
The QR965mn project covers mainly the three northern segments in the Doha area.
The second contract of approximately QR1.065bn covers the central segment of the main trunk sewer and the third, worth QR1.123bn, includes the construction of the southern segment of the main trunk sewer.
Speaking at the meeting, Ashghal president and senior engineer Nasser Ali al-Mawlawi said many more essential infrastructure projects - being implemented in the next few years to develop and improve the connectivity and related infrastructure to such mega projects as Doha Metro, Lusail Light Rail, Hamad Port in southern Doha and three economic zones - are under different stages of construction.
When completed, the Idris programme will provide a long-term waste water treatment solution to meet the agricultural needs and requirements of Doha, Al Wakra and Messaieed.
The programme is being implemented to upgrade and expand southern Doha's sewerage infrastructure even while meeting the needs of the country's growing population.
The tunnelled interceptor sewer and advanced sewage treatment works being built as part of Idris will meet the long-term demands of southern Doha for the next 50 years. It will eventually do away with more than 35 existing pump stations, Ashghal president said.
The construction works include a nearly 70m deep terminal pump station.
The programme's conveyance system covers a distance of over 40km of deep main trunk sewer and over 70km of lateral interceptor sewers.When completed, the advanced sewage treatment plant on the southern side will have an initial capacity to handle 500,000 litres a day.
