  • Use of generalized extreme value covariates to improve estimation of trends and return frequencies for lake levels

    One of the most important tools in water management is the accurate forecast of long-term and short-term extreme values for flood and drought conditions. Traditional methods of trend detection are not suited for hydrologic systems while traditional methods of predicting extreme frequencies may be highly inaccurate in lakes. Traditional frequency estimates assume independence from trend or initial ...

  • Scottish Water Flow Monitoring Contracts

    Scottish Water commissioned HL in 2007 to deliver two separate flow monitoring contracts to help improve the water companies understanding of the yield and low flow conditions at several water supply catchments across Scotland. One project involved the installation of reservoir level, inflow flow gauges and recording raingauge devices in nine reservoir catchments in South West Scotland. Although ...

  • Introducing pressure and number of connections into water loss indicators for French drinking water supply networks

    In France, the system of performance indicators defined within the relevant regulations does not include indicators relating to pressure, or the number of connections. So, Irstea and Veolia Water decided to create a new system of water loss indicators designed for use in France and that would take into account these parameters. The study was initially carried out at District Metered Area (DMA) ...

  • Rethinking Big Water - Is It Time For A New Approach To Municipal Water Infrastructure?

    Las Vegas has long served as a stereotype of human excess: gambling, drinking, sex, all-you-can-eat buffets. But the latest chapter is playing out away from the Strip, in the part of the valley where two decades of booming development have swelled the population to 2 million residents who rely on a dwindling water supply. Ninety percent of the southwestern U.S. city’s drinking water comes ...

  • Preventing rain water flooding case study

    SmartScan 50 helps preventing rain water flooding by providing an efficient level measurement solution in a pop. 1M city. The municipality has been struggling for years with heavy flooding of rain water during winter time that damaged large parts of the city and caused distress to its residents. As a result, a long drainage pipe was laid between the city's shore and the flooded parts. This huge ...

  • Aligning theory and measurement in behavioral models of water conservation

    Discussion in the water literature has called for research on the role of behavioral intentions in explanations of both water demand and water conservation. But previous research has suggested that individual-level motivations are not good predictors of metered household water consumption. Two possible reasons for the lack of association between intentions and actual water conservation are that: ...

  • The mystery of electronic water treatment unveiled

    The problems of scale are well known to those living and working in "hard" water areas. Scale is the undesirable consequence of water supplies becoming super-saturated with dissolved minerals.  These problems are of greater significance if found in industrial water systems and commercial buildings. Scaling problems commonly occur, even in "soft" water areas, when a fluid stream is ...
