Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Rooftop Runoff for Water Supply A theoretical approach was developed in an attempt to answer the first of the three ques tions. In figure 1 vector P' represents the rainfall; its length is proportional to the rain fall amount passing through a unit area normal to the flow path. The angles p and a are its direction with respect to the horizon and a reference meridian, respectively. A rain gage, with its opening in a horizontal plane, will receive P' sin d units of rainfall. The angle a will not affect the catch. Place a sloping roof in this same rain-flow field and determine the unit rainfall catch of the roof. Let a horizontal element of the roof be the reference meridian. The direction of the horizontal component of the rainfall vector with respect to the meridian is a. The angle of the rainfall vector with respect to a horizontal plane is y}. The slope of the roof is S. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Water is the essential resource that is becoming extremely scarce worldwide. The 21st century will further stress all available water resources through the growth and expansion of developing nations. It is not only the quantity of cheap water that is being depleted, but the quality of these waters is being endangered. Florida is an example where rapid development and an exploding population are competing for shrinking groundwater resources. Current water use does not address the use of alternative supplies and reuses in the United States. The objective of this research was to determine a strategy for augmenting existing water supplies with alternative sources that could be developed economically. Having reviewed numerous alternative sources, it was determined that runoff from roofs potentially provides a source that might meet the augmentation requirement for a small community of a population of 30,000 or less. This research has shown that the quality of water collected from five different roof surfaces meets the drinking water standards and will not degrade the current quality of the main source of water supply. This work not only required the collection of hydrological data from the roof systems, but chemically and biological analyzes samples for contaminants. Since rainfall events vary periodically and in duration, 100,000 meteorological events were analyzed for wind speed, relative humidity, rainfall intensity, and the rainwater runoff across five roofing surfaces to analyze variables that contribute to the effects on the water quality of the source. The model establishes the economics and the public health value of this water. The research assesses the local regulatory aspects of using the water with the outcome of a working objective and rational decision matrix that will permit agencies to select an optimal and safe utilization of the water sources.

Download or read book Rainwater Tank Systems for Urban Water Supply written by Ashok K. Sharma and published by IWA Publishing. This book was released on 2015-05-15 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rainwater tank systems have been widely adopted across the world to provide a safe local source of water in underdeveloped rural areas, a substitution for mains water for non potable end uses in water stressed urban areas, as well as providing flooding control in monsoonal climates such as Korea, or combined sewer systems such as Germany. The importance of these systems in cities has grown, as water managers seek to provide a range of decentralised solutions to supply constraints of current water supply systems, whilst reducing the impact of urban development on the natural environment, and increasing resilience to the impacts of climate change. Rainwater tank systems are now often implemented under integrated urban water management (IUWM) and water sensitive urban design (WSUD) philosophies, which take a holistic view of the urban water cycle. Rainwater Tank Systems for Urban Water Supply is based on a comprehensive, multi-million dollar research program that was undertaken in South East Queensland (SEQ) Australia in response to the Millennium drought when the water supply level in the regions drinking water dams dropped to 17% in July 2007 and the area came close to running out of water. In particular, the book provides insights and detailed analysis of design, modelling, implementation, operation, energy usage, economics, management, health risk, social perceptions and implications for water quality/quantity of roof water runoff. The approaches and methodologies included in Rainwater Tank Systems for Urban Water Supply inform and validate research programs, and provide insights on the expected performance and potential pitfalls of the adoption of rainwater tanks systems including: actual harvested yield and resulting mains water savings, optimal sizing for rainwater storages and roof collection systems, expected water quality and implications for managing public health risks, modelling tools available for decision support, operation and management approaches of a decentralised asset at the household scale and community acceptance. The book is suitable for use at undergraduate and post graduate levels and is of particular interest to water professionals across the globe, who are involved in the strategic water planning for a town, city or a region. It is a valuable resource for developers, civil designers, water planners, architects and plumbers seeking to implement sustainable water servicing approaches for residential, industrial and commercial developments.

Download or read book Using Graywater and Stormwater to Enhance Local Water Supplies written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-07-30 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chronic and episodic water shortages are becoming common in many regions of the United States, and population growth in water-scarce regions further compounds the challenges. Increasingly, alternative water sources such as graywater-untreated wastewater that does not include water from the toilet but generally includes water from bathroom sinks, showers, bathtubs, clothes washers, and laundry sinks- and stormwater-water from rainfall or snow that can be measured downstream in a pipe, culvert, or stream shortly after the precipitation event-are being viewed as resources to supplement scarce water supplies rather than as waste to be discharged as rapidly as possible. Graywater and stormwater can serve a range of non-potable uses, including irrigation, toilet flushing, washing, and cooling, although treatment may be needed. Stormwater may also be used to recharge groundwater, which may ultimately be tapped for potable use. In addition to providing additional sources of local water supply, harvesting stormwater has many potential benefits, including energy savings, pollution prevention, and reducing the impacts of urban development on urban streams. Similarly, the reuse of graywater can enhance water supply reliability and extend the capacity of existing wastewater systems in growing cities. Despite the benefits of using local alternative water sources to address water demands, many questions remain that have limited the broader application of graywater and stormwater capture and use. In particular, limited information is available on the costs, benefits, and risks of these projects, and beyond the simplest applications many state and local public health agencies have not developed regulatory frameworks for full use of these local water resources. To address these issues, Using Graywater and Stormwater to Enhance Local Water Supplies analyzes the risks, costs, and benefits on various uses of graywater and stormwater. This report examines technical, economic, regulatory, and social issues associated with graywater and stormwater capture for a range of uses, including non-potable urban uses, irrigation, and groundwater recharge. Using Graywater and Stormwater to Enhance Local Water Supplies considers the quality and suitability of water for reuse, treatment and storage technologies, and human health and environmental risks of water reuse. The findings and recommendations of this report will be valuable for water managers, citizens of states under a current drought, and local and state health and environmental agencies.
