The type of the station will be type 1 as the flow is less than 100 I/sec.

The pumps are selected to delive 「 the required flow at calculated total head. Pumps are of submersible type with non-clogging mixed-flow impellers. Pumps and motor drives are selected to satisfy the final design flow. The internal diameter of the wet well will be 3.2 m as shown in tender drawings.

5.3 Holding tank

A temporary holding tank is to be constructed in the north side of ADPTV. The holding tank is divided into two compartments. It will be furnished with inlet pipe receiving flow from the discharge chamber In addition, outlet pipe will be provided and furnished with end cap/plug to allow for future connection once the planned sewerage treatment plant is completed and operated

If there has been a 汜 vision to design ordered by the ADDC after approval of the shop drawings and after ordering the materials, consideration will be made on paying for the resulting surplus materials based on the ADDC's and/or ADDC's acceptance of a properly documented claim.

The responsibility for assessment of Materials Quantity is with the CONTRACTOR CONTRACTOR does not have to wait for either processing his shop drawings or quantity authorisation by the ADDC and/or ENGINEER, for ordering materials once the material data sheets are approved. Any material that becomes surplus, due to over estimation by the CONTRACTOR will not be paid for and such materials will be the property of the CONTRACTOR

It shall be the CONTRACTOR's sole responsibility to orde 「 a certain amount of material necessary for the uninterrupted completion of the WORKS to compensate for material losses due to cutting of pipes , wastage, at no extra cost to the ADDC

The TENDERER shall include extra costs, if any, associated with part ordering of materials.
