“…In the 2022 paper "Water ATMs and Access to Water: Digitalization of Off-Grid Water Infrastructure in Peri-Urban Ghana" by Amankwaa, Heeks, and Browne [13], they explored water ATM implementation in a peri-urban Ghanaian community. The study highlighted water ATMs' incremental nature shaped by socio-material dynamics [13]. The case study emphasized the significance of a situated socio-technical approach, stakeholder engagement, affordability, accessibility, and leveraging existing community infrastructures.…”

This proposal outlines the development of a comprehensive solution to address hydration challenges through the creation of a Smart Water ATM with Arduino integration, RFID authentication, and dynamic dispensing capabilities. Traditional water dispensers often fall short in monitoring water intake and promoting optimal hydration practices. In response, our project aims to revolutionize hydration practices by integrating Arduino Mega and Uno boards into a Smart Water ATM with a Bottle Dispenser. This innovative system is designed to dispense specific water quantities based on user preferences, encourage the use of personal water bottles, display water temperature, and operate independently without the need for a water line connection. Prior to prototype fabrication, an extensive literature review and survey were conducted to understand existing water dispenser shortcomings and gather public perspectives in Singapore. The Smart Water ATM addresses identified issues by incorporating sensors to monitor water levels, dispense specific quantities, and measure water temperatures. The prototype fabrication involves designing a stainless-steel housing, 3D printing the Smart Water dispenser unit, and installing tanks, tubing, and electronic components. To enhance user interaction, the Smart Water ATM requires RFID authentication through Identity Cards, tracking daily water consumption. An LCD screen displays the dispensed water volume over the ATM’s lifespan, motivating users to be mindful of their water consumption and minimize wastage. Adjustments will be made for deployment in public spaces, such as train stations, where access to permanent water dispensers is limited. This proposal presents an innovative solution to promote enhanced hydration practices, encouraging users to adopt mindful water consumption habits.

“…The impact of the computerised billing system on revenue collection has been emphasised in the water and sanitation industry (Amankwaa et al 2021). According to Opiyo and Mwalili (2020), spot billing in water utilities enhances service delivery by eliminating human involvement and lowering the risk of fraud and billing errors.…”

Water utilities play a critical role in providing safe and reliable water services to the public. However, ensuring efficient service delivery can be challenging, especially in areas with limited resources and inadequate infrastructure. In recent years, the use of mobile technology has emerged as a potential solution to address some of these challenges. This study examines the influence of a mobile SMS bill query application on the service delivery of two water utilities, NAWASSCO and NAIVAWASCO, in Nakuru County. This study aimed to determine the influence of mobile SMS bill query applications on service delivery by NAWASSCO and NAIVAWASCO water utilities in Nakuru County. Delone and McLean's IS success model, derived from the information systems (IS) theory, guided the study. A cross-sectional survey research design was adopted to achieve this, and data were collected using a structured questionnaire. Purposive sampling was used to select 33 and 24 staff in NAWASSCO and NAIVAWASCO water utilities, respectively. The Census method was employed since the target population was less than 100. Descriptive and inferential statistics were used to analyze the data. OLS regression analysis was used to test the hypotheses at a 0.05 significance level. The OLS regression analysis revealed that mobile SMS bill query applications significantly influenced water service delivery in water utility companies (β = 0.212, p < 0.05). Water utility companies in Nakuru County should continue investing in and promoting the mobile SMS bill query application.

“…An analysis that could be used to characterize this hydraulic accessory would be to estimate the pressure drop and its coefficient of loss [13,14] with working gauge pressures not exceeding 275.79 kPa. In this way, if the loss coefficient could be known for a range of home flows in low-pressure networks, this information could serve as technical input for planning urban water infrastructure projects with low-pressure networks such as those located in developing countries and thus adapt these devices in future housing constructions such as those supported by smart city models [15,16]. Therefore, estimating the loss coefficient could be useful to project the energy requirement of pumping systems capable of supplying the precious liquid to home networks with this adapted system.…”

The potable water in residential hydraulic networks is measured using volumetric meters. However, when the water carries air bubbles or pockets through the pipes, the accuracy of the meter readings is reduced, which can negatively impact the billing that users pay for their water consumption. A check valve accessory exists that reduces the size of these air bubbles to correct the meter readings and improve the service experience. However, the device has only been tested for networks with relative pressures higher than 275.79 kPa. This research proposes to characterize the hydraulic behavior of the accessory through an experimental procedure in which the operating conditions are similar to those found in water networks in Latin America, where the networks have relative pressures lower than 275.79 kPa. The study found that the accessory significantly reduces the coefficient of loss for velocities greater than 1 m/s. The use of the device is suggested in flow regimes with Reynolds numbers close to 20,000 for operating conditions of temperatures close to 25 °C and residential pipes with an internal diameter of 20.9 mm and a flow velocity between 1.3 m/s and 1.78 m/s. This condition allows it to operate with minimal local energy loss and a low coefficient of loss, providing an improved service experience.
