Riventa Finds Potential Savings in Las Vegas

11 March 2021

Las Vegas Valley Water District’s (LVVWD) mission is to optimize its water distribution, and Riventa has identified potential savings of 12% - equating to USD $254,000 per year. Utilizing its leading-edge thermodynamic FREEFLOW technology, Riventa monitored pumps at the Hacienda Water Pumping Station (WPS), a strategic part of the district’s network, which is also part of the Southern Nevada Water Authority (SNWA). 

Previously, it had not been possible to accurately assess the efficiency of the seven fixed-speed drywell pumps, which transfer potable water to a regulator tank at another site – but Riventa soon established that savings of 7.4% (equivalent to USD $154k per year) would result from refurbishing four of the pumps.

Savings of at least 4.8% (USD $100k per year) could also be achieved through pump scheduling at Hacienda WPS, which was built in 1981, with assets upgraded in 1996.

Initial data findings showed that the least efficient pump was used the most during the first 2-weeks of the project period. Using all data, Riventa made real-time recommendations for pumping combinations, based on demand, finding savings of 4.8% (USD $100k per year) that could be achieved through pump scheduling. Three pumps required no maintenance, while four were deemed priorities for refurbishment, which would deliver further savings of 7.4% (USD $154k per year).

While providing further training, Riventa is also collaborating with LVVWD’s operations team to customize a control-room interface. This will ensure that real-time information from FREEFLOW.
