Efficient minimum night flow analysis using Bayesian inference
This study examines a plan for efficient leakage investigation to decide the number of survey-subjected water meters in the Option A method, which requires considerable manpower and expense, along with possible civil complaints, among the possible methods for determining the minimum night flow. The Bayesian approach was adopted, and the prior distribution of night use and water supply pipe ...

Investigations into under-registration of customer meters in Palermo (Italy) and the effect of introducing Unmeasured Flow Reducers
Abstract: During the last two years, Palermo Water Utility and Palermo University have been investigating the under-registration of customer meters installed upstream of private storage tanks and the effect of introducing Unmeasured Flow Reducers (UFRs). The first series of tests consisted of measurements (inlet pressure, tank inflow, tank outflow) for two individual users located in different ...

Domestic Metering - Do we understand all the issues as we move into AMP 4?
Untitled Document The number of domestic properties in the England & Wales currently paying for water by volume, i.e. via a water meter, is about 25%. Current projections estimating the number of households paying for water by meter in each company by 2030 is between 35% and 90% depending on the company. The rate at which meter penetration is expected to ...

How to Read a Water Meter in the USA
Water meter reading doesn't have to be complicated. The first thing you need to do is locate your water meter. If you live in the Northern United States where winter temperatures drop below 32 degrees Fahrenheit, you might be surprised to know that it's actually in your house. Check your basement near your furnace or hot water heater. In colder regions of the United States, water meters are ...

Advancing household water-use feedback to inform customer behaviour for sustainable urban water
Sustainable water management is increasingly essential in an age characterised by rapid population growth, urban and industrial development and climate change. Opportunities to promote conservation and water-use efficiencies remain attractive in directly reducing water demand. Smart water metering and the provision of detailed water-use feedback to consumers present exciting new opportunities ...

How to Read a Water Meter to Detect a Leak
After examining your last water bill, you’re worried that you’re using too much water, or worse, you have a water leak in your home. And you’re not alone. According to the EPA, 10 percent of homes in the US have leaks that waste 90 gallons or more each day. You’ve already instituted a 5-minute shower rule and your sprinklers are on timers. You’re thinking you must ...

Smart Water Metering Market in Asia Pacific to surpass US$ 300Mn by 2024
The Smart Water Metering Market in Asia Pacific Market is set to grow from its current market value of more than $85 million to over $300 million by 2024; as reported in the latest study by Global Market Insights, Inc. Invariable need to limit consumptions levels, dictated by a host of national policies concerning sustainable water utilization will drive the APAC smart water metering market size. ...

Case Studies Demonstrate the Implications of Metering Errors
General anomalies that occur in the management of apparent losses are identified and include determination of apparent loss indicators that fail to take into account both the random and bias errors inherent in metering. Estimating the volume of water losses that could be attributed to meter errors is also incorrectly assumed to be equivalent to the error limits (i.e. envelope) stipulated in ...

What is a water audit and how does it benefit your business?
A preliminary desktop water audit is the first step to saving you money on your water bills. There are many different charges and tariffs that make up your water and waste water bills for example: – Water Volume charges Waste water volume charges Water meter standing charges Waste water meter standing charges All of the above vary according to site water and waste water volumes ...

How Does a Water Flow Meter Work?
A water flow meter is a device that measures the amount of water flowing through a pipe. There are several water flow meter technologies to choose from depending on the water measurement application, maintenance requirements, and budgetary terms. Each of these types of water flow meters has a unique principle of operation, specific application benefits, and overall cost-of-ownership. The ...

Assessing the relevance of intervening parameters on the per capita water consumption rates in Brazilian urban communities
ABSTRACTThe determination of the per capita water consumption is an essential step in the design of water supply systems. The present paper examines the influence of several variables on the per capita water consumption, based on 96 different towns in the Brazilian state of Minas Gerais. The set of samples was categorised firstly into five different classes and three distinct population intervals ...

A mathematical model to evaluate apparent losses due to meter under-registration in intermittent water distribution networks
Apparent losses consist of water volume drawn from the network, consumed by users but not paid for. Those due to water meter under-registration were evaluated by means of a mathematical model able to analyse the complexity of intermittent supply systems with private tanks. This supply scheme is very common in the Mediterranean area where unexpected water shortage often happens and intermittent ...

Stakkabox ultima connect chamber - Case study
THE CHALLENGE The Water and Sewer Department in Arlington, Virginia had a specific problem area behind a commercial plaza. The difficult location of a loading dock was causing trucks to damage the area’s 3-meter pits. Drivers had to make tight turns when coming and going, harming the curb where the meters were located and affecting the local commercial plaza and businesses. Arlington ...

Estimating residential water demand in the absence of volumetric water pricing
Rapid population growth has significantly increased the magnitude of water shortages in California. Although water shortages already exist, some of the state's utility systems are still not providing their residents with financial incentives for water conservation. Instead of using water meters to charge households according to their actual water usage, they are charging a flat fee for unlimited ...

Sound recording to characterize outdoor tap water use events
Obtaining disaggregated water use at the home typically involves expensive smart metering. In this study, water use events at the outdoor tap were captured using recorded sound. Outdoor taps at 10 homes were fitted with small-sized microphones and digital sound recorders. Sound files recorded over a 1-month period were used in the analysis. In the preliminary analysis, a human operator ...

Consumption estimation with a partial automatic meter reading deployment
Automatic water meter reading (AMR) is now the best kind of technology to supply real time information on water consumption. Complete equipment of a district metered area enables the assessment of the total consumption of a finite size population, for a time scale sometimes as short as an hour. However, its cost for generalization can generate high capital expenditures (CAPEX), unaffordable for ...

Pro-poor water service strategies in developing countries: promoting justice in Uganda's urban project
Water service to the urban poor presents challenges to political leaders, regulators and managers. We identify technology mixes of yard taps, public water points (with and without pre-paid meters) to meet alternative constraints, and reflecting populations served and investment requirements. Three investment scenarios have different implications for improving water access to over 400,000 citizens ...
