This project involves the electrical rehabilitation of an approximately 50 year old primary pump station.  As a sub-consultant to CP&Y, GEI designed the upgraded 4160V, 480/277V and 208/120V electrical distribution systems This includes the replacement of all of the high service pump and well pump starters, high service pump motors, power panels, low voltage transformers, lighting, pressure instruments, level instruments and flow instruments.  The existing SCADA system PLC is also being replaced. GEI also provided emergency design services for the fire damage to the motor control center that occurred prior to the start of this project.

 

Project: Emergency Electrical Engineering Services For Basin Fire Damage (Basin Pump Station)


Basin Pump StationLocation: San Antonio, Texas
Owner: San Antonio Water System
Client: San Antonio Water System
Duration: 2012
Construction Cost: $507,216

Grubb Engineering was contracted by SAWS for emergency engineering services after a fire damaged part of the existing indoor motor control center (MCC).  The plant was only half operational after the fire.  Another fire occurred during the design that resulted in the complete destruction of the entire MCC.  As directed by SAWS GEI expedited the design of a new temporary replacement to part of the MCC so the plant could be put back on line. The new MCC was located in a new prefabricated building that can be relocated if needed in the future.  GEI’s technical services team provided assistance to the contractor that installed the new equipment.  GEI continued the design as part of the Basin Pump Station Improvements Project – Phase I which, among other improvements, involves the replacement of entire MCC that was damaged by the fire.

power engeratorGrubb Engineering was involved as a sub-consultant in a project that involved a 7.5MGD expansion of the Medio Creek WRC facility.  As part of the preliminary engineering work, the existing plant was investigated for possible electric distribution and control upgrades.  The expansion included electric power distribution, cutting edge local control and security system.  Investigation of electric utility service alternatives was conducted as part of the design. The control system automates many plant functions and allows for operator control of certain functions onsite. The total estimated load for this project was 1500kVA which included a full backup power generator system. The project included the design of a new lift station to serve both the new and existing plants. The lift station has pumps with VFD’s and soft starters.  Project is complete.

Mission Pump Station

Project: Mission Pump Station Improvements
Location: San Antonio, Texas
Owner: San Antonio Water System
Client: San Antonio Water System
Duration: 2008-2013
Construction Cost: $11,842,000

This project involved the complete redesign and replacement of the existing 4160V electrical, instrumentation, SCADA, security and control systems. Construction was completed in 2012.

Grubb Engineering was the Prime Consultant for this project and had several specialized sub-consultants. The existing switchgear, MCC, ductbank system and SCADA system were analyzed to determine condition and salvage value. GEI designed the replacement of the existing 4160V electrical distribution including medium voltage MCCs to new high service pump motors and low voltage MCCs to new well pump motors; designed both local controls and SCADA controls for all pumps; designed high service pump discharge valve controls as well as controls for flow control valve; designed power distribution and controls for replacement chlorine and fluoride feed systems; designed generator backup for chemical feed systems to include chlorine scrubber system; and designed SCADA system complete replacement and security upgrades at this 60+ year-old, 68 MGD facility.  GEI’s sub-consultants design work included the replacement of piping, well head rehab and pump building renovation.  The tank rehabilitation project for this location was completed as a separate project by GEI as a sub-consultant which required extensive coordination between projects.

The pump station involved special attention since it was located inside an existing building with many space constraints. GEI meet with CoSA officials and coordinated the design of the building upgrades with them. Special equipment and permitting was needed since the building expansion included chorine gas storage. The site is located in the San Antonio River Improvements Overlay district which required special attention.
