TYJT was responsible for the Treated Water Transmission System portion of the contract, which included the booster stations, water treatment plants, service centers and remote sites. The design scope included field verification, preliminary design, final design and providing assistance with field installation, calibration of instruments and start-up.

The pre-field verification consisted of the following tasks, submittal of access request and equipment shutdown schedule and gathering all available documents that pertain to the station. Field verification consists of the following tasks, verification of the process and instrument drawings (P&ID), gathering data for all existing instruments, assessing the instrument for proper installation, verifying instrument calibration, trace field wiring and develop control documents, produce field sketches of the existing cable and conduit and layout of the proposed new cable and conduit. Pictures are taken of the equipment and instrumentation at the station for future reference.

The preliminary design package consisted of the following, control narrative, process and instrument drawings, instrument list, DCS input and output list, loop diagrams, cable and conduit schedule.

The final design package consisted of the following, control strategy, process and instrument drawings, instrument list, DCS input and output list, loop diagrams, cable and conduit schedule, graphic templates, ovation RTU and ROS equipment layout, instrument data sheets for purchase equipment, and conduit layout. Interfacing the new SCADA system with the existing/new instrumentation and process equipment. Providing procurement specifications, calibration ranges and set points for the new/existing station instruments.

TYJT engineers were on site during field installation of the new DCS and provided assistance with the identification of wiring and terminations. The engineers played a key role during the phase over and start-up of the DCS at each facility. All equipment and instrumentation was checked for the correct wiring and terminations at the piece of equipment and at he DCS. During phase over, each piece of equipment and instrumentation was tested for proper functionality first locally, then at the local DCS Remote operator Station (ROS) and then at the System Control Center ROS.

Status of Project:
The project is substantially complete and has been in operation since July 2005.
