TL;DR: Telephone surveys and focus groups were used to identify the ways that households that have acquired tanks, either by choice or through development conditions, interact with their tank water and highlight the lack of maturity of domestic rainwater tanks as an acceptable technology.
Abstract: Over the past decade, there has been rapid installation of domestic rainwater tanks in many Australian cities in response to drought, and facilitated by subsidies and development regulations. Tanks have been portrayed as a challenge to the dominance of 'big water' and a means of elevating routine interactions with water to a practical consciousness that can stimulate lasting changes in the way that water is consumed. Telephone surveys and focus groups were used to identify the ways that households that have acquired tanks, either by choice or through development conditions, interact with their tank water. Meaning was attributed to tank water in at least three distinct ways that highlight the lack of maturity of domestic rainwater tanks as an acceptable technology. Some saw the water as a personal supply to safeguard their lifestyle against restrictions. Others understood their tanks as a personal contribution to the communal environment by reducing dependence on mains water supply. The third group regarded the tank as an extension of the water supply infrastructure. The existence of mandatory connections from tanks to internal infrastructure, such as toilet and laundry facilities, correlated strongly with the likelihood that tank water was not seen as a personal resource. Tanks perpetuate the distinction between basic water supplies and luxury water that was established during water restrictions under drought conditions.

TL;DR: In this paper, the authors examined the impact of intermittent supplied piped water on the quality and quantity of water delivered to residential taps in Hubli-Dharwad, India, when compared to continuous piped-water supply.
Abstract: In at least 45 low- and middle-income countries, piped water systems deliver water for limited durations. Few data are available of the impact of intermittent water supply (IWS) on the water quality and quantity delivered to households. This thesis examines the impact of intermittently supplied piped water on the quality and quantity of water delivered to residential taps in Hubli-Dharwad, India, when compared to continuous piped water supply. A framework for understanding the pathways through which IWS can impact water quality is first developed. The extent to which contamination occurs in Hubli-Dharwad is quantified by comparing microbial water quality throughout the distribution system in an intermittent system and a continuous system in the same city. The mechanisms affecting water quality in the IWS network in Hubli-Dharwad are identified by measuring changes in water quality over time using continuous measurements from pressure and physico-chemical sensors paired with grab samples tested for indicator bacteria. In the final chapter, a new method of measuring household water consumption in an IWS when supply durations are limited and few metered data are available is developed. This thesis showed that the intermittent supply was frequently subject to contamination in the distribution system and that households with intermittent supply consumed limited quantities of water. While these results demonstrated that converting to a continuous water supply can improve water quality when compared to intermittent supply, this conversion may not be possible in the near future for resource-constrained towns and cities. This thesis contributes to knowledge of the mechanisms causing contamination and constricting water access in IWS systems, which can help improve systems to ensure that people with piped water receive water that is reliable, safe, and sufficient.

TL;DR: In this paper, the authors present an investigation on the operation of a novel active beam system installed in an office building located in Jonkoping, Sweden, which consists of two parts: a dedicated outdoor air system (DOAS) to satisfy latent loads and ventilation requirements, and a water circuit to meet sensible heating and cooling loads.
Abstract: This paper presents an investigation on the operation of a novel active beam system installed in an office building located in Jonkoping, Sweden. The system consists of two parts: a dedicated outdoor air system (DOAS) to satisfy latent loads and ventilation requirements, and a water circuit to meet sensible heating and cooling loads. The novelty of the system is in relation to the water circuit, which is able to provide simultaneous heating and cooling through a single water loop that is near the room temperature. The energy performance of the system is currently being monitored through a number of sensors placed along the water circuit. Relevant physical parameters are being measured and data are available through a monitoring system. A preliminary analysis shows that the system is performing as designed. Results are shown for a typical week in winter, spring and summer. In particular, the supply water temperature in the circuit was between 20°C (in summer) and 23.2°C (in winter). The maximum supply/return temperature difference was found in summer and it assumed a value of 1.5 K. It is noticed that in spring supply and return water temperatures almost overlap.

TL;DR: In this paper, the authors illustrate the importance of community involvement in rural water supply projects by examples taken from the authors work in Zimbabwe and South Africa, and examine the options of commercially produced handpumps against pumps manufactured at village level, and the broader choices of borehole development, spring supply, and photovoltaic pumping.
Abstract: This paper illustrates the importance of community involvement in rural water supply projects by examples taken from the authors work in Zimbabwe and South
Africa. It further examines the options of commercially produced handpumps against pumps manufactured at village level, and the broader choices of borehole development, spring supply, and photovoltaic pumping (PVP). The principal objective of the Zimbabwe work is to
assist rural farmers to become self sufficient in food production, and to improve nutrition levels through dry
season vegetable production. However, the technology developed was also applied by the local communities to water supply.
The projects in Southern KwaZulu Natal are concerned with village water supply. The Crisis Intervention Program (CIP) aimed to provide primary water supply to communities suffering from drought and lack of infrastructure.

TL;DR: In this article, an automatic spring conveying device consisting of a left-spring supply channel and a right-spring-supply channel was proposed for conveying inner springs in the utility model.
Abstract: The utility model discloses an automatic spring conveying device. The automatic spring conveying device comprises a left spring supply channel and a right spring supply channel, wherein a pipe cavity moving device which can move up and down is arranged between the left spring supply channel and the right spring supply channel; a spring in-place sensor and a spring supply conveying hose are arranged in the left spring supply channel; and a spring conveying channel and an air channel are formed in the right spring supply channel. When automobile key switches are produced by a full-automatic production device, the device is used for conveying inner springs; manual operation is not needed, the production efficiency is improved, and the labor is saved; and the problem about conveying of springs in complicated equipment is solved.
