the sewerage collection network, pumping stations,
raising mains and irrigation network. The design &
supervision consultant for both the contracts are
M/s. Khatib and Alami with Metcalf & Eddy.
Sewerage Network:
The construction contract of sewerage network
collection system in Bausher is awarded to M/s. Sino
Hydro Corporation, China for RO. 57.8 million after
a very thorough tendering process. The Construction
Contractor (Sino Hydro) has established its office
in Muscat and in the process of completing

mains from Azaibah PS to Al-Ansab STP and Treated
Effluent Network for irrigation purposes in the
area. It also includes all electrical works at the
pumping stations and control & automations work.
Al-Ansab STP:
This part involves building a new sewerage treatment
plant adjacent to the existing STP. The STP is
designed to handle 53,000 m3/day of sewerage.
Due to the size of this plant and the fact that it
will be the monitoring center, Distributed Control
System (DCS) and Supervisory control and Data
Acquisition system (SCADA) will be installed to
control & monitor all the remote stations /
facilities; build operation center which covers
offices, warehouse & staff accommodation with all
related facilities which will enable the operator to
monitor and supervise the entire process.
Al-Ansab plant is based on using the Membrane
Bioreactor (MBR) Technology which is considered as
one of the leading technologies in the Industry.
Once commissioned, Al-Ansab plant will be the
largest of its kind worldwide using the MBR
technology. The plant capacity is 53,000 m3/day.
The Contractor, M/s. Galfar Engineering &
Contracting Co. LLC has started the construction
activities.
Darsait STP Upgrade:
The up-grading works of Darsait STP is nearly
completed. This major rehabilitation project was
carried out to replace the ageing equipments with

process structures.
The upgraded plant capacity is 21,000 m3/day
compared to 14,000 m3/day earlier.
M/s. Khatib & Alami with Metcalf & Eddy and Bahwan
Contracting Company are the Design & Supervision
Consultants and Construction Contractor for this
project respectively.
Darsait Network Extension:
