BexarMet Water District Hill Country Water Works Pump Station #2, San Antonio, Texas

BexarMet Water District Hill Country Water Works Pump Station #2 is a new project for Klotz Associates in the Hill Country, where they have needed the water as much as we have in Houston, if not more so.  We are finalizing the scope, but ultimately we are going to redesign a pump manifold to increase the efficiency of a High Power Pump Station.

City of Seguin Water Line Project, Seguin, Texas
Klotz Associates is working on the scope but is planning to design approximately a mile worth of 12-inch water main to attach to existing 8-inch main.  There will be a bore under a TxDOT roadway.  The line is proposed within a fully developed area.

Austin Clean Wastewater Program – West Rim Wastewater Line, Austin, Texas
Klotz Associates provided preliminary professional engineering services into constructing a maintenance access road, five creek crossings, and eight manholes and demolishing two lift stations for an existing wastewater line that had been experiencing major overflowing problems. The Preliminary Engineering Report researched the replacement of eight iron bends in the pipe with eight manholes. There were also sections of asbestos concrete line that had to be removed with special care. The Report also involved coordination between many governmental departments such as the City of Austin, Texas Parks and Wildlife, the Texas Historical Commission, and the U.S. Army Corps of Engineers.

City of Houston Rehabilitation of Beltway Wastewater Treatment Plant, Houston, Texas

Klotz Associates provided Phase I, II and III engineering services for rehabilitation of the Beltway Wastewater Treatment Plant.  The project included new aeration systems and blowers, extensive electrical work including new medium voltage distribution to both blower buildings, rehabilitation of the chlorination and de-chlorination systems and rehabilitation of the Return Sludge Pump Station.  Replacement and rehabilitation of the blowers required careful planning and design of a sequence of construction to allow the plant to remain fully operational during construction activities. Our experience with large blower rehabilitation and replacement on this project has prepared us to effective and efficiently perform the blower replacement required for the Sims North WWTP project. Construction of this project was completed in early 2008.  The final construction cost was 4.6% under the bid amount.  The Kalluri Group was a major subconsultant to Klotz Associates on this project, providing electrical and instrumentation and control engineering.

San Jacinto Water Authority Woodlands Division Sanitary Sewer Rehabilitation, The Woodlands, Texas

Klotz Associates has assisted the San Jacinto Water Authority, Woodlands Division with their sanitary sewer rehabilitation over several years. Klotz Associates provided engineering consulting services in the evaluation phase, design phase and construction administration and construction observation stage.

City of Humble Water System Model & Water Plant Improvement, Humble, Texas
Klotz Associates’ scope for this project included modeling the City’s water system, topographic survey, geotechnical, electrical work, structural design, complete design including plans, specifications and cost estimates, bid phase services, and construction phase services.

Klotz Associates’ understanding of the City’s system and their needs at Water Plant No. 7 made this a successful project. We solved the right problems with the funding that was available to the City at the time, and the water system model allowed us to fine-tune the pump station design for future needs. Our consistent contact with the TCEQ on the regulation changes and requirements has kept the City ahead of the game on necessary changes to their disinfection systems and take-point requirements.

Klotz Associates prepared the design for improvements to the City of Humble’s Water Plant No. 7. The work was done in two phases. The first phase of the project included the construction of a 1.0 million-gallon prestressed concrete ground water storage tank and a temporary pump station. This phase of the project also included the demolition of two hydropneumatic tanks and three bolted steel water tanks. The second phase of the project included the construction of a new pump station at Water Plant No. 7 to upgrade the pump sizes.

Tomball Design of Southside Utilities, Tomball, Texas
Klotz Associates designed the largest infrastructure project the City of Tomball has undertaken to date. The Southside Utilities Project included almost 4 miles of 12-inch water line, 3 ½ miles of 4- and 6-inch gas line, and more than 3 miles of 18- to 30-inch sanitary sewer from 8 to 30 feet deep. A 12-foot diameter triplex lift station at the South Wastewater Treatment Plant also was part of the design. Project construction began in February 2004; its completion is anticipated in Spring 2005.

Aside from the size of this project, the real challenge was coordination with multiple jurisdictions and affected stakeholders. A Texas Department of Transportation (TxDOT) highway, construction by the Harris County Flood Control District, a railroad track, a radio tower, and countless invaluable trees were adjacent to project construction. Dozens of homes and businesses along the alignment of the utilities were affected, and continuous access to each had to be maintained during the 14-month project.

Klotz Associates prepared design that was functional, practical and cost efficient. The firm also managed coordination with numerous entities, business owners, and property owners to make this job a success.
