The surface water penstock shall be located at the junction manhole of the Al Waab SW network and the Al Aziziya Street SW network. The manhole No. SW13/3/28 is connected downstream to a 1400mm diameter pipe leading to Al Forousiya street at one end and to an 800mm diameter pipe to Al Aziziya network, while an 1000mm diameter pipe upstream is coming from Al Waab Street SW network. The proposed surface water penstock shall be installed inside the manhole at the 800mm diameter pipe connection to the Al Aziziya SW network. During the rainy season, the surface water penstock shall remain closed at all times to prevent flooding on Al Aziziya Street.

The Contractor shall supply, install and configure the operating system of the penstock at the existing SR124 Pumping Station through a proposed RTU-01 with necessary power supply as shown on the drawing EDS1511/EL/402 Rev. D00. Accordingly, the scope of work includes the supply, installation, testing, and commissioning of the surface water penstock at the junction of the Al Waab and Al Aziziya surface water networks, including but not limited to all necessary civil, electrical, mechanical and instrumentation works all as per the drawings and specifications.
