City of San Antonio River Water Treatment Plant (Zoo)
The importance of the San Antonio River to the physical health and economic health of the City of San Antonio is almost immeasurable. Clean, attractive, and inviting water in the San Antonio River and the River Loop and its extensions must be maintained using sustainable and cost effective features and best management practices. To assist in protecting the quality of the water in the San Antonio River, Klotz Associates is assisting the City of San Antonio with planning, design, and construction of a water treatment plant to disinfect dry weather flows discharging into the San Antonio River from the San Antonio Zoo. The San Antonio Zoo discharges about 1,700 gallons per minute or about 2.5 million gallons per day of water to the San Antonio River during dry weather. The discharge from the Zoo contains high levels of bacteria which contribute to water quality degradation in the river. Environmental clearances and regulatory permits will be required to implement the project.
The Ultraviolet Disinfection process will be housed in a water treatment plant adjacent to the Zoo outfall. The peak plant capacity will be 3.88 mgd (for “dry weather” flows) with stormwater being by-passed around the plant.
Design was completed in 2011, and construction is expected to be completed in 2012.
City of Houston Sanitary Sewer Relief Tunnel, Houston, Texas
Klotz Associates was responsible for the preliminary and design phase services of sludge transfer facilities from White Oak, Northwest, Turkey Creek, and West District sewage treatment plants. The Team designed an extension of a deep tunnel that was needed. The design included 127,000 linear feet of force main construction with materials analysis and utility coordination. Klotz Associates managed the construction phase, traffic control, and odor control system as well.
City of Palestine Water Treatment Plant Improvements, Palestine, Texas
Klotz Associates was selected for making improvements to 9.5 mgd Water Treatment Plant which would increase the raw water pump capacity and provide a variable speed pump to stabilize flow through the plant. Klotz Associates added flow split facilities coming into the plant and replaced chemical feed systems at the river and plant while adding variable speed flocculator drives. The replacement of effluent weirs coming out of the sedimentation basins was evident as well as the replacement of filter media and the rework of backwash facilities. The improvements upgraded the plant safety while the rework to the operations and chemical feeds greatly improved the taste and odor of the water. Klotz Associates replaced plant controls to allow for more automated and uniform control. The overall plant capacity was increased to 13 mgd with additional sedimentation and filter facilities
North Harris County Regional Water Authority - SCADA Project, Houston, Texas
This project included planning, design and construction phase services for a supervisory contract and data requisition (SCADA) system for 53 separate locations within the Authority's 2010 Water Transmission System. The project was done on a fast-tracked basis using a High Technology Procurement process. This assignment under our On-Call Contract provided consulting services related to SCADA and organizational / operational issues in the Authority.
San Patricio Municipal Water District, Water System Expansion, Ingleside, Texas
The San Patricio Municipal Water District (SPMWD) is a wholesale water provider to municipal and industrial users in San Patricio and Aransas County, Texas. SPMWD embarked on a multi-year program to meet the needs of a growing industrial and municipal demand for water. This multi-year program included planning, design and construction of the upgrade of existing facilities, and design and construction of new facilities. Klotz Associates was responsible for management of other consulting firms throughout the duration of the project including:
- Planning of required treatment facilities and related infrastructure based on population projections from municipal users and input from area industries for future water needs.
- Process study and design to support the re-rating of the SPMWD existing conventional treatment plant from 6 to 9 MGD. The project included negotiation with the TCEQ
- Process evaluation for a new 9 MGD treatment plant to provide potable water to the SPMWD’s municipal and industrial water customers. The study evaluated several candidate technologies and included bench and pilot scale testing. Membrane filtration was ultimately selected for the new treatment plant.
- Hydraulic analysis and design of new transmission lines
- Led meetings with various stakeholders and the TCEQ
- Design and construction management of the new membrane filtration plant, known as “Plant C.” This plant was one of the first membrane filtration plants for potable water in the state of Texas. The plant included sedimentation as membrane pretreatment, membrane filtration utilizing microfiltration membranes, chemical feed systems, ground storage tanks, modification to existing clearwells, high service pump station, and new transmission lines.
The project included several subconsultants all operating under separate contracts to the SPMWD (civil, architectural, electrical, geotechnical, surveying, environmental, construction inspection and construction materials testing) as well as managing specialty teams in various offices of the prime consultant.
To meet project deadlines, the project was divided into three separate equipment procurement contracts and four construction contracts.
