Civil Engineering Water Treatment System: Case Study

Problem

The water treatment system at Tuolumne Meadows in Yosemite National Park, originally constructed in 1967 and upgraded in 1984, had become outdated and inefficient. This aging infrastructure struggled to meet the needs of park employees and the growing number of visitors. The remote location, limited staff, and seasonal operation posed significant challenges to maintaining and operating the system effectively.

The specific challenges included:

• • Outdated Technology: The existing system could not efficiently handle current water treatment demands.
  • Limited Operating Staff: The remote location and limited staff made it challenging to operate and maintain the system.
  • Seasonal Operation: The system required reliable procedures for winter shutdown and reopening.

Solution

HECO Engineers developed a comprehensive modernization plan for the Tuolumne Meadows water treatment system. This included evaluating alternative treatment technologies suitable for remote sites, automating the filtration process, and integrating analytical instrumentation for enhanced monitoring. The design also allowed for future integration into the park-wide SCADA system for remote monitoring and included provisions for reliable winter shutdowns and seasonal reopening procedures. HECO Engineers devised a comprehensive plan to modernize the Tuolumne Meadows water treatment system.

The solutions included:

• • Evaluation of Technologies: Conducted a thorough evaluation of alternative treatment technologies suitable for remote operations with limited staff.
  • Design Improvements: Automated the filtration process and incorporated analytical instrumentation for better monitoring.
  • SCADA Integration: Prepared the design for future integration into the park-wide SCADA system to enable remote central monitoring.
  • Winterization Provisions: Included provisions for system shutdown during winter and seasonal operational procedures.

Results

The modernization project significantly improved the water treatment system’s efficiency and operational capabilities at Tuolumne Meadows. Automated processes and analytical instrumentation streamlined operations, while remote monitoring capabilities reduced the need for on-site staff. Effective winterization procedures ensured reliable seasonal operations, enhancing the overall functionality and reliability of the water treatment system.

The modernization project led to significant improvements in the water treatment system at Tuolumne Meadows:

• • Enhanced Efficiency: Streamlined operations with automated processes and analytical instrumentation.
  • Remote Monitoring: Increased capability for monitoring the facility from a central location, reducing the need for on-site staff.
  • Seasonal Reliability: Implemented effective winterization procedures, ensuring reliable seasonal operations.
