Lampasas Wastewater Treatment Plant

Operational Continuity in a Complex Brownfield Environment

The primary hurdle was the development of a multi-stage, 4.5-acre industrial wastewater treatment facility (WWTP) within the constraints of an active food processing plant. Key complexities included:

• Brownfield Integration: Executing construction in close proximity to ongoing operations, requiring phased work and controlled tie-ins to prevent production downtime.

• Subsurface Congestion: Navigating a dense network of existing and new underground utilities, which demanded real-time routing adjustments and proactive clash resolution.

• Strict Technical Requirements: Managing high-level segregation between power, control, and communication systems while ensuring grounding integrity and hazardous material compliance for chemical dosing areas.

• Regulatory & Environmental Hurdles: Adhering to stringent stormwater management and erosion control protocols, particularly within potential floodplain impacts.

Arcadia delivered a highly coordinated, multi-system integration that synchronized process, structural, electrical, and civil engineering. The solution featured:

• Comprehensive Process Systems: Integration of physical, chemical, and biological treatment stages, including rotary drum screening, MBBR (Moving Bed Biofilm Reactor), and dual-stage DAF (Dissolved Air Flotation) units.

• Robust Electrical Framework: Expansion of existing plant switchgear and the installation of a dedicated Motor Control Center (MCC) supporting multi-voltage distribution (480V, 208/120V, and 24VDC).

• Advanced Automation & Control: Deployment of extensive instrumentation and communication infrastructure to monitor open-air tanks and interconnected piping networks.

• Civil & Safety Engineering: Development of concrete containment for chemical storage, underground stormwater systems, and site-wide security features designed to merge seamlessly with existing plant facilities.

Through disciplined construction sequencing and proactive field engineering, the project achieved:

• Seamless Plant Integration: Successful facility startup with minimal disruption to the primary food processing operations.

• Regulatory Compliance: Full adherence to discharge requirements and environmental safety standards through a synchronized commissioning of mechanical and biological systems.

• Optimized System Performance: A validated control environment that ensures precise process tuning and reliable instrumentation across the 4.5-acre site.

• Strategic Infrastructure Growth: A future-proofed wastewater solution that supports the plant's long-term operational capacity and environmental stewardship goals.
