M/E Roundtable of water to wash their hands regardless of which faucet is turned on. Providing hot water in toilet room sinks is a good engineering practice, as warm water is necessary for proper sanitation. Also, the use of tempered water in sensor faucets is desirable in cold-weather climates. Energy would definitely be saved (as well as first cost) if hot water were not provided at places where it was not required. I think it would depend more on the climate and desires of the owner. CSE: What O&M issues are green buildings finding in the field from water-saving technology: gray water, rain harvest, no-flush urinals, etc. BANSE: Keeping flush valves in Ask the experts: no-water urinals At www.csemag.com/askthe experts, CSE gives its readers and Web visitors the opportunity to pose questions directly to the panelists. Below is a question for June’s topic, specifically about no-water urinals. “ How are waste materials from no-water urinals disposed of?” —Tony [last name withheld], mechanical engineer, Atlanta From medical to telecom to aerospace, industries with mission-critical power requirements trust Cyclon® batteries for reliable backup power. The reason is Cyclon batteries’ advanced design: Thin-plate, spiral-wound technology delivers more power over more discharge cycles. An industry-ﬁrst, valve-regulated design eliminates “dry out” failure. And rugged metal casings maintain plate compression for consistently higher voltage. For more about why so many industries rely on Cyclon batteries for dependable back-up power, visit www.enersys.com. J. PATRICK BANSE: Trap seal liquids will generally wear out or degrade through prolonged use and will be “flushed out” with the liquid urine waste. Replacement of the floating liquid layer would be in accordance with the manufacturer’s recommendations. The trap type seal is removed with a special tool and disposed of with normal solid waste products such as paper towels and related refuse. SHAWN MARTIN: Cartridges are simply discarded with traditional waste. Some manufacturers provide bags in which to place the used cartridges before disposal. Many manufacturers encourage the draining of the cartridges and recycling of the plastic. The cartridges are not classified as hazardous waste. Another option is that most sealant liquids may be discarded in the municipal waste system.
