Book Description
Modern Potable Rainwater Harvesting 2nd Edition is a major expansion and rewrite of the first edition by the same title. This book shows how to design, build, and maintain a rainwater system that consistently and reliably provides clean drinkable water to your whole house. This water is orders of magnitude cleaner than typical public water supply or well water simply due to the fact that source water is distilled water from the sky rather than ground water polluted with all kinds of toxins. Rather than trying to purify polluted water at high mass flow rates demanded of entire cities, a rainwater harvester maintains distilled water purity with low continuous flow through inexpensive filters and disinfection systems. This book discusses advanced oxidation processes (AOP), disinfection, biofilm control, filtration, plumbing and pumps, electronic controls, water testing, and system management using a spreadsheet. System sizing using a spreadsheet and local average rainfall data found on the Internet is discussed. How to survive droughts is discussed. How to build a low-cost high flow rate prefilter and motor-driven first-flush valve is taught. This valve is controlled by an Arduino microcontroller that receives inputs from a digital rain gauge, water level sensors, and user selection of first flush amount. Instructions are provided for building capacitive tank level sensors. Various types of digital rain gauges are discussed, including tipping bucket rain gauges (TBR), capacitive sensor gauges, and acoustic resonance gauges. The section on TBR gauges shows how to build a constant drip rate calibrator for TBR gauges with common plumbing hardware. Three different types of common capacitive gauges are discussed. Temperature compensation of the variation of dielectric constant with temperature or speed of sound in air is discussed, using both hardware and software. Three essential electronics controls are discussed including; a transfer pump controller, an Arduino-based pressure pump runtime monitor, and an Arduino-based first flush valve controller. C-code Arduino sketches are provided. Wireless control of the rainwater system is discussed, using a Raspberry Pi computer interfaced with the Arduino microcontroller through Xbee transceivers. Python source code for a GUI interface running on a Raspberry Pi is provided. Mathematical equations are necessarily provided for systems design, but a reader comfortable with algebra and trigonometry, or first-year calculus should have no trouble with the math. This book contains a vast amount of technical details on rainwater harvesting not found in any other book. Although primarily geared toward the self-taught DIY person, this book can be used in the classroom to teach potable water professionals.

Book Description
Rainwater Harvesting for Drylands and Beyond, Volume 2, 2nd Edition is a how-to guide enabling you to “plant the rain” by creating water-harvesting “earthworks” or “rain gardens.” Earthworks are simple, inexpensive strategies and landforms that passively harvest multiple sources of free on-site water including rainfall, stormwater runoff, air conditioning condensate, and greywater within “living tanks” of soil and vegetation. The plants then pump the water back out in the form of beauty, food, shelter, wildlife habitat, timber and forage, while controlling erosion, reducing down-stream flooding, dropping utility costs, increasing soil fertility, enhancing the soil carbon sponge, recharging groundwater and springs, and improving water and air quality. This dramatically revised and expanded full-color second edition builds on the information in Volume 1 by showing you how to turn your yard, school, business, park, ranch, and neighborhood into lively, regenerative producers of resources. Conditions at home will improve as you simultaneously enrich the ecosystem and inspire the surrounding community. Learn to select, place, size, construct, and plant your chosen earthworks. All is made easier and more effective by the illustrations of natural patterns of water and sediment flow with which you can collaborate or mimic. Detailed step-by-step instructions with over 550 images and expanded water-harvesting principles or guidelines show you how to do it, and plentiful stories of success motivate you so you will do it!

Book Description
Modern Potable Rainwater Harvesting shows how to design, build, and maintain a rainwater system that consistently and reliably provides potable water that is orders of magnitude cleaner than typical public municipal water. The book covers advanced oxidation processes, disinfection, biofilm control, filtration, plumbing, electronic controls, and water testing. Electronic schematics of essential control circuits are provided. Plumbing diagrams for both on-grid and off-grid systems are provided. Proper pump sizing for a given storage capacity is discussed. The book shows how to use a spreadsheet to properly size storage capacity based on actual rainfall data, collection area, and assumed daily usage rate. Mechanical design and fabrication details of key components are provided, such as automatic first flush divert valves, a rainwater pre-filter, disinfectant injection, and a water level sensor. The book contains unique information not found anywhere else, some of which disputes the teachings found in other sources. As one book reviewer put it, "I thought I knew everything there is to know about rainwater harvesting, but this book is lightyears ahead of anything I've seen." The book is not written by an armchair theoretician, but by an actual practitioner who has successfully maintained a system on his own private residence, as the only source of potable water, for several years. The book also demonstrates how private rainwater harvesting stimulates real water conservation, as opposed to the futile efforts of governments and public utilities.

Book Description
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.
