City of Ramsey Local Water Supply Plan <br />Low Flow Fixtures/Appliances - Plumbing fixtures and appliances that significantly reduce the <br />amount of water released per use are labeled "low flow". These fixtures and appliances use just <br />enough water to be effective, saving excess, clean drinking water that usually goes down the <br />drain. <br />Maximum Daily Demand - The maximum (highest) amount of water used in one day. <br />Metered Residential Connections - The number of residential connections to the water system <br />that have meters. For multifamily dwellings, report each residential unit as an individual user. <br />Percent Unmetered/Unaccounted For - Unaccounted for water use is the volume of water <br />withdrawn from all sources minus the volume of water delivered. This value represents water <br />"lost" by miscalculated water use due to inaccurate meters, water lost through leaks, or water <br />that is used but unmetered or otherwise undocumented. Water used for public services such as <br />hydrant flushing, ice skating rinks, and public swimming pools should be reported under the <br />category "Water Supplier Services". <br />Population Served - The number of people who are served by the community's public water <br />supply system. This includes the number of people in the community who are connected to the <br />public water supply system, as well as people in neighboring communities who use water <br />supplied by the community's public water supply system. It should not include residents in the <br />community who have private wells or get their water from neighboring water supply. <br />Residential Connections - The total number of residential connections to the water system. For <br />multifamily dwellings, report each residential unit as an individual user. <br />Residential Per Capita Demand - The total residential water delivered during the year divided <br />by the population served divided by 365 days. <br />Residential Water Use - Water used for normal household purposes such as drinking, food <br />preparation, bathing, washing clothes and dishes, flushing toilets, and watering lawns and <br />gardens. Should include all water delivered to single family private residences, multi -family <br />dwellings, apartment buildings, senior housing complexes, mobile home parks, etc. <br />Smart Meter - Smart meters can be used by municipalities or by individual homeowners. Smart <br />metering generally indicates the presence of one or more of the following: <br />• Smart irrigation water meters are controllers that look at factors such as weather, soil, <br />slope, etc. and adjust watering time up or down based on data. Smart controllers in a <br />typical summer will reduce water use by 30%-50%. Just changing the spray nozzle to <br />new efficient models can reduce water use by 40%. <br />• Smart Meters on customer premises that measure consumption during specific time <br />periods and communicate it to the utility, often on a daily basis. <br />• A communication channel that permits the utility, at a minimum, to obtain meter reads <br />on demand, to ascertain whether water has recently been flowing through the meter <br />and onto the premises, and to issue commands to the meter to perform specific tasks <br />such as disconnecting or restricting water flow. <br />55 April 7, 2017 <br />
