Providing essential water resources from the City of Houston’s East Water Purification Plant along Clinton Drive to the City of Galena Park’s business district.

The City of Houston's East Water Program consists of 12,700 linear feet of 96-inch diameter and 1,035 linear feet of 72-inch diameter water mains.  BBI's engineering services provided the plans and specifications, final design and basic construction phase services. The project consisted of a steel pipeline installed in a tunnel system and included block valves, air/vacuum valve assemblies, pressure regulating valves (6-inch to 14-inch) for distribution system connections, and over 3,000 linear feet of distribution lines.  An additional 354 linear feet of 72-inch, 60-inch, and 48-inch large diameter water mains were installed in open cut. The construction was performed with minimal disruption of normal activity, since the tunnel shafts were located approximately 2,000 linear feet apart. 

BBI is committed to improving the quality of life within communities by implementing the very latest engineering technologies and techniques.

Comprising the initial phase of the City of Houston Northeast Water Purification Plant System, BBI designed in three phases the Northeast Water Purification System for Houston Area Water Corporation and Montgomery Watson Harza Constructors.  The technical work included design of:

• 120 million gallon per day (mgd) intake structure
• 570 linear feet of 78-inch raw water intake conduit
• initial 40 mgd raw water pumping station
• 6,355 linear feet of 66-inch raw water pipeline
• approximately 30,500 linear feet of 84-inch steel finished water transmission main
• approximately 12,300 linear feet of 42-inch ductile-iron finished water transmission main. 

The intake structure consists of an intake manifold comprised of four, dual-end 42-inch diameter screened openings which draw lake water into a 96-inch vertical intake pipe.  The pumping station will be built in three phases: Phase I has a firm capacity of 40 mgd, Phase II has a firm capacity of 80 mgd, and Phase III has a firm capacity of 120 mgd.  Both constant speed and variable speed pumps will be used.  Phase I shall consist of three 20 mgd pumps.  Two 20 mgd pumps will be added for Phase II.  All five 20 mgd pumps will be replaced with 30 mgd pumps for Phase III.  The pumps are single stage, vertical turbine pumps.  The station design consists of a 108-inch buried suction header, five 54-inch individual pump feeds and five 60-inch diameter can pump barrels.  The motors are housed in a CMU block building which contains a ten ton crane.  The 66-inch raw water pipeline connects the raw water pumping station to the water purification plant.  From the plant, design work includes installation of a 84-inch and 42-inch finished water transmission main including design of air release and drain line valves, butterfly valves, fittings, service connections, appurtenances, and utility relocations.

Designing a large diameter water main to serve citizens of Houston, BBI provided the final engineering design and construction phase services for the City of Houston's Surface Water Transmission Program.  The design of the water main consisted of approximately 9,250 linear feet of open cut 84-inch water main.   

Work to accommodate the 84-inch water main included replacing 3,080 linear feet of 8-inch water line and 4,225 linear feet of augured 8-inch sanitary sewer and sewer utility relocations.  A combination of open cut and tunnel construction was utilized, which included tunneling 160 linear feet across the Pecore Fault Zone.

Designing 12,100 linear feet of 36-inch water lines for communities located in West Harris County, BBI provided the final design and construction phase services for the West Harris County Regional Water Authority - Contract 11.  The open cut, augured and cased water main included valves, fittings, meter and pressure flow control stations, as well as appurtenances.  This design was constructed along a former pipeline easement from just south of the intersection of Keith Harrow Blvd and West Harrow Drive, eastward to just north of Langham Creek in West Harris County.

Supplying water to two Municipal Utility Districts and future water line expansion to communities along Lockwood Drive off Beltway 8 (north) in Harris County, BBI designed approximately 8,400 linear feet of 24-inch open cut, augured and cased water main.  

At the mid and end points of this Water Transmission Line, 12-inch and 10-inch lines branch off and convey water to a metering station and a pressure reducing station at each location. 

BBI coordinated and reviewed efforts performed by subconsultants, which included surveying, geotechnical, environmental, corrosion protection, and hydraulic transient analysis services.  BBI design staff also coordinated efforts with various utility Authorities in order to prevent conflicts with those utilities, as well as with various petroleum pipeline companies and a railroad company whose facilities are crossed by the water line.
