A thorough, balanced, informative and educational book about reducing water consumption, reusing "clean" water (aka greywater) and the importance of conserving waterways... and best of all, this is for your average person. We use potable (drinkable) water for everything from flushing toilets to watering plants - and then treat it all the same as sewage, resulting in overuse of chemicals and general water waste. Does anyone see a problem with this? The author did. Part I of this book (the first 3 chapters) explains the "why", while Part II explains the "how", for catching, harvesting and storing both greywater and rainwater, including how to create raingardens and install irrigation systems.

You're not expected to know anything about this topic at the beginning, so definitions, examples and explanations are provided in an easy-to-read and memorable format, completed with clear and annotated illustrations, before/after examples and inset tips. If, for instance, you're more interested in different types of toilet than in the problems caused by dams, you can quickly find the sections most relevant to you.

The facts of our American water usage may be surprising or even shocking to you, and some of the methods to reduce wastage are shocking in their simplicity. (You may also be reading it thinking, "People have to be told to do that?" but you'll still find points of interest and easy-to-implement ideas, though you may need to compromise on some if you share your space, and others may make you back away slowly.) Tips are often grouped and graded for ease of implementation as well as cost, making comparison and decision-making a breeze, and she recommends some good places to begin.

This book seems to cover everything you need to know, including some side notes and relevant conversions for those who live in colder climates or who can't easily think in gallons per week. It's not heavy on science/math, but includes enough to be of interest and to help you calculate your water and watering needs while planning any changes. It even includes tools and parts lists and "been there done that" advice to smooth your path and prevent mishaps during installation, along with case studies to show real life applications.

The author is aware that greywater systems may be illegal in your state (and indeed had to work to change the laws in her own), so do check the laws in your area and be mindful when making changes!

The substantial "Resources" list at the end of the book gives plenty of websites and books for every topic mentioned, including some beginner's guides on landscaping and plumbing to get your skills up to par if you're not as handy as you'd like. The Water-Wise Home can provide you with reference material and projects for many years, as you gradually make changes and improvements to your house and landscaping. It's going on my to-buy list.

Recommended for the environmentally-conscious, conservationists, people who want to know more about the workings of their home, those trying to reduce their dependence on the existing water/sewer system, and people seeking to reduce their water bills.

At first glance, I thought this might be another DIY book on frugal and sustainable ways to save some water. We already have the low-flow toilets, harvest rainwater, and try to plant it places to best use the natural terrain and conserve.
What I wasn't expecting, and what is hidden in the title, is becoming Water-Wise. Not just for your home, but everyone in your home becoming wise about the water table and system in your area.
This is a wonderful, cause-effect-solution book that is easy to read, well illustrated and extremely informative.
You won't find a list of ten projects to save you some water. But you will find a detailed complete home and landscape walk-through that will help you prepare, establish, and implement ways to get the whole family on board saving water.
This isn't just about cutting your water bill, this is about sustainability and environmental impact and change that we can all take part in.

For people who are already sure they can and should do more about water than turning off the tap while they brush. Laura Allen is one of the original Greywater Guerrillas and their early publications were galvanizing and energetic--but also a zine-mare of missing pages and cut-off photocopies. inspired action, but not confidence. here, though, we have all the diagrams and formulae you can shake a pipefitting wrench at, along with the calm, accepting tone of people who have dealt with major diy and lived to tell about it. Very sensible section on rain-barrel design.

Great resource for anyone wanting to make even a minimal change in their water use. And if you want to REALLY commit, the author has information on composting toilets and urine-saving techniques. Ewwww! There are discussions pro and con on all the different systems as well as drawings and graphics to help you set-up and get on board. She has the experience and authority to write about this topic and can call on the authority of other experts in this new field of water conservation.

The Water-Wise Home is the most thorough, yet readable resource for people interested in conserving water at home. Ms. Allen show all of the currently available options, including DIY options, for greywater systems, low water use appliances and toilets, rainwater reclamation, and composting toilets. There is a large section on water conscious landscaping with and without using greywater. Though readers can tell that most of the information is aimed toward those living on the West Coast, it is certainly applicable to anywhere in the US.

Awesome resource - make someday happen TODAY!

Great book full of practical questions answered: when, where, how, why, what, who, which -- EVERYTHING. Includes legal stuff and more. If you are to get one book on this topic at all, I highly recommend this one! Oh, and there are diagrams, too, for the visually inclined. So no excuses, if you've always thought that someday you might just want to do all this. Someday is today. Get it. NOW.

This is a really great resource for learning about water use in your home and how to use less or use smarter. The author really knows what she is talking about. There is something for everyone to think about in this book from someone just wanting to save a little money and use less water to someone ready to go all out and make major changes to their home. It was an interesting read.

I received a free copy of this book through a Goodreads giveaway.

A lot of useful information. Unfortunately, the greywater system would never pass code where I live. I will pickup a copy of this book again once I purchase property and can plan the system from the start.

I got this book from goodreads fist reads. It is a wonderful resource if you own a home but if you rent, live in a condo/apartment/etc or have no yard most of this book cannot be used. One of the nice things is that this is just about as self contained a resource as you can possibly get.

Great resource though.

Absolutly the number one between my non-fiction books I have read in 2016.

This book has several tops:
1) Ebook - I never saw e-book technically well organized like this. It is so structured and well designed, it was a pleasure to read it on the e-book device. Hyperlinks, references, fonts, illustrations, paragraphs. Very, very nice. This book is definitely not only quick conversion from its paper version.

2) Content - this book is full of knowledge, practice. You are not the plumber? So far. Never mind, you will be, the book will teach you. Author has a deep knowledge from real installations and the book proof it. Many tips like "do not do it this way as in few years the pipe will broke"...

3) Illustrations - never saw so beautiful hand-made illustrations in non-fiction book.


As you will see, some people live modern and comfortable lifestyles relying on a mere 8 inches of annual rainfall.


The author maybe could not imagine, this book will read by people around the whole world, not only in USA. Sometimes she talks a little bit about different weather zones (freeze, snow, too hot), but the problem NO 1 is called "units". If I am reading about yards, feet and gallons, I can make some approx. conversion in my head to meters and liters. But if the author is using sophisticated equations for water supply of your tree, where you put several input values, it uses some operators and constants and you get the water amount... The only solution is rewrite whole equations into meters, liters - and use new constants. Also thanks to units being out of my comfort zone I read this book several months instead of several weeks. Maybe in next version of this nice book - I prefer both units, e.g "5 inches (12.7 cm)".
