Global Water Stewardship
Ramboll auditors provided two to four days of onsite auditing services at each facility, including a review of historical water usage/cost data, walkthroughs of major water consuming processes, identification of gaps in flow metering/monitoring, and discussions on previous water reduction initiatives. At the completion of each audit, Ramboll submitted a report providing a breakdown of water intake/discharge accounting, a comprehensive water usage schematic, and recommendations for improvement opportunities with order-of-magnitude cost estimates for implementation and payback period. Identified opportunities varied for each site and encompassed a full spectrum of water uses, such as:
- Segregation and recycling of relatively clean rinse streams through reverse osmosis
- Optimization of/reduction in landscaping irrigation systems
- Replacement of boiler/steam vacuum system with mechanical vacuum and cogeneration facility
- Reduction of cooling tower evaporation with hybrid wet/dry units.
