At one of the most prestigious universities in Asia, the main campus comprises a large number of buildings clustered within an area less than 2 km2 (1.2 mi2). Because the university was built more than a century ago, many facilities on the campus were never fitted with the proper instrumentation for energy measurement, making it difficult or impossible to monitor the performance of most HVAC systems, including the cooling system.
After having been reluctant of using clamp-on ultrasonic flow meters for energy measurement in cogeneration plants in large residential and commercial buildings, a U.S.-based engineering firm was convinced by the clamp-on meter’s strengths.
A case of legionellosis — an illness acquired from Legionella bacteria, which can grow in cooling water and potable water systems — was diagnosed at a medical retirement home.
In 2007, White House Utility District (WHUD), a water utility serving approximately 90,000 consumers and businesses in Tennessee, faced a dilemma: how to meet a projected growing demand for water within the budget and capital constraints faced by municipal and mid-sized utilities everywhere.
Like wastewater treatment plants across the country, Village Creek Water Reclamation Facility experiences fluctuations in the volume of water to be treated due to the inflow and infiltration of stormwater. During storm events, this variation can be between X and Y mgd.
Not cool enough in summer. Not warm enough in winter. Guests staying at a prestigious country club in New York state complained regularly about the air conditioning and heating of their luxury suites and apartments. The geothermal heat exchange system serving this facility had never, in fact, been fully functional.
One of the nation’s largest four-service utility providers, Colorado Springs Utilities supplies energy and water to over 450,000 people. The state-certified laboratory of the Water Quality Assurance section processes over 14,000 samples and 80,000 analytes per year from eight watersheds, seven finished water treatment facilities, 38 finished water reservoirs, four post-chlorination stations, two wastewater treatment facilities, and over 2700 miles of pipeline.
A municipal wastewater treatment plant investigated a sudden increase in fecal coliform exceedance events.
Using historical data and Seeq analytical software, Nukon calculates when sewer blockages will occur up to 13 hours before occurrence, preventing spills.
“We have too much data” is the refrain we continually hear from water utilities. It’s no surprise that managing data from multiple sources and turning it into business insights presents a daunting challenge; however, data influx does not have to be a burden. When managed well, there’s no such thing as too much data, especially if your business is implementing a big data strategy — a topic that has implications and reach beyond the scope of this paper.
