Conference Program - WateReuse Association

WATER REUSE &DESALINATIONBRIGHT AS THE FLORIDA SUNIn 2005, the Hotel used about 18.5 million gallons ofwater, with a daily average of just over 50,000 gallons perday (gpd). Although toilet and urinal flushing are acceptableapplications of recycled water under California Codeof Regulations Title 22 Water Recycling Criteria, the citywas initially only approved to distribute recycled waterfor landscape irrigation prior to preparation of an engineeringreport. However, even before the use wasapproved for the project, the hotel went ahead andinstalled dual plumbing of the main lobby restroomswhile upgrading the restrooms and adjacent banquetfacilities.Hotel Sofitel is deserving of the title “Customer of theYear” because of its proactive approach in expanding thesafe use of recycled water beyond the common uses.Although in the end the health department did notapprove the use of recycled water in the hotel swimmingpool and commercial dishwasher, the hotel’s requestchallenged regulators to consider new applications thatmay appear in the future. With four approved recycledwater applications, the hotel has more onsite uses thanany other Redwood City customers.WateReuse Person of the YearAndrew Salveson, P.E., Project Manager, Carollo Engineers(Walnut Creek, CA)Nominated by: Patrick Bollman, P.E., AquionicsAndrew Salveson’s contributions to the water reuseindustry have often come in the form of research. He hasserved as the principal investigator on multipleWateReuse Foundation research projects focusing ontreatment technologies. He also has worked on variousdisinfection planning and design projects and has performednumerous full-scale and pilot-scale performanceevaluations of disinfection systems. Mr. Salveson’sresearch has included performing virus, bacteria, andhydraulic testing in accordance with the National WaterResearch Institute (NWRI)/Awwa Research Foundation(AwwaRF) UV guidelines. All projects have included regulatoryinteraction for the permitting of the facility andfor the permitting of the technology with the CaliforniaDepartment of Health.Mr. Salveson’s cutting edge work has often pushed theboundaries. For example, though the NWRI Guidelinescall for flow velocity profiling and comparison foraccepting full scale designs, Mr. Salveson’s data collectionand testing allowed him to develop an alternative calledCheckpoint Biossay, which has gained acceptance amongregulators and the water industry. The Checkpoint Bioassayis practical, cost-effective, far superior to flow velocityprofiling, and helps protect public health through properequipment implementation at each site.Mr. Salveson is well respected and highly regarded for hisunderstanding of the importance of water reuse and theregulations that drive its importance. He is used by majorUV manufacturers in conducting validations for reuseand especially in meeting the NWRI Guidelines. Thoughhis work with UV occupies a majority of his investigations,he has spent time exploring other areas ofdisinfection including pasteurization and ozonation.Recent findings have suggested that the combination ofmultiple disinfectants and chemicals improves overalldisinfection performance.WateReuse Person of the YearLauren Walker-Coleman, Water Reuse Specialist,Florida Department of Environmental Protection (Tallahassee,FL)Nominated by: Florida Water Environment Association’sWater Reuse CommitteeLauren Walker-Coleman has served Florida as a WaterReuse Specialist for over eight years. She has been aprime contributor to Florida’s award-winning WaterReuse Program (accolades include WateReuse Institutionof the Year and EPA’s 2006 Water Efficiency LeaderAward). She makes numerous presentations and hasauthored numerous technical papers dealing with a widerange of subjects related to water reuse. Ms. Walker-Colemanmanages and produces DEP’s annual reuseinventory and was a contributor to the development ofthe WateReuse Association’s National Databse of WaterReuse Facilities. She also manages DEP’s Pathogen MonitoringDatabase and the Pathogen Monitoring Program.She has served on advisory committees for severalWateReuse Foundation research projects and has managedseveral DEP-funded research projects dealing withpathogen issues.Ms. Walker-Coleman is an effective member of Florida’sReuse Coordinating Committee and has participated inseveral rulemaking activities associated with water reuse.12
