IWS Completes Design-Build of Texas Wastewater Treatment Plant
PROJECT TYPE: Private Utilities, Residential Development
SERVICES: Construction, Design-Build, Engineering, Permitting, and Start-up
TECHNOLOGIES: Activated Sludge, Membrane Bioreactor (MBR)
SUSTAINABLE / WATER REUSE: Landscape / Subsurface Irrigation
Sustainable Solution Meets Budget Constraints
Integrated Water Services, Inc. (IWS) successfully completed the design, construction, and start-up of a new wastewater treatment plant for the Lerin Hills Subdivision in Kendall County, Texas. This facility was engineered to handle flows up to 110,000 gallons per day, with start-up turndown capacity of 11,000 gallons per day. Upon completion, the plant was transferred to the Lerin Hills Utility District for ownership and operation, serving the subdivision’s residents.
Challenges Faced:
- Meeting stringent Texas Commission on Environmental Quality (TCEQ) tertiary discharge limits.
- Designing a wastewater treatment system that accommodates future growth while being cost-effective for the client’s budget.
- Project complexity demanding precise coordination.
Solutions Implemented:
- Secured project with a cost-effective, collaborative design that met all discharge requirements.
- Deployed a complete mix activated sludge wastewater treatment system with an ISO disc cloth media filter for advanced tertiary treatment.
- Installed a comprehensive, turnkey system that was fully compatible with the existing collection system.
- Managed the entire project lifecycle, from design and construction to site improvements and system start-up.
Outcome and Impact:
- IWS delivered a wastewater treatment plant with a capacity of 110,000 gallons per day (GPD), with turndown capability to 11,000 GPD.
- The plant met the TCEQ’s stringent discharge limits for BOD of 5 mg/l, TSS of 5 mg/l, ammonia of 1 mg/l, and phosphorus of 0.5 mg/l.
- IWS’s cost-effective solution satisfied the client’s budgetary requirements.
Key components of the treatment system include:
- Aeration Chamber
- Mechanical Clarifier
- Sludge Holding Chamber/Aerobic Digester
- Iso-Disc Cloth Media Filter for membrane filtration
- Disinfection Equipment
- Post Aeration Tank and Pump System
These units work together to achieve efficient nutrient and organic matter removal, essential for water quality improvement. Additionally, sedimentation tanks and sludge treatment systems ensure compliance with environmental standards, while minimizing the environmental impact of the operation.
In addition to site improvements and the concrete pad, IWS oversaw the start-up of the treatment facility, collaborating closely with Ashbrook Corporation to ensure seamless operation. The project highlights IWS’s commitment to renewable energy and innovative treatment solutions for wastewater treatment facilities.
Abel Godines, the owner’s representative for LH Devco, Inc. was pleased with the project. “IWS really made this a smooth project, from working with the site civil engineer and completing the design, to constructing the system, and then doing the start-up. This was a complex project and needed creative thinking to provide a solution for the budget we had. IWS added value to the project and I would highly recommend them for future projects.”
