Earthworks are one of the easiest, least expensive, and most effective
ways of passively harvesting and conserving multiple sources of water in
the soil. Associated vegetation then pumps the harvested water back out
in the form of beauty, food, shelter, wildlife habitat, and passive
heating and cooling strategies, while controlling erosion, increasing
soil fertility, reducing downstream flooding, and improving water and air
quality.
Building on the information presented in Volume 1, this book shows you
how to select, place, size, construct, and plant your chosen
water-harvesting earthworks. It presents detailed how-to information and
variations of a diverse array of earthworks, including chapters on mulch,
vegetation, and greywater recycling so you can customize the techniques
to the unique requirements of your site.
Real life stories and examples permeate the book, including:
- How curb cuts redirect street runoff to passively irrigate
flourishing shade trees planted along the street.
- How check dams have helped create springs and perennial flows in
once-dry creeks
- How infiltration basins are creating thriving rain-fed gardens
- How backyard greywater laundromats are turning “wastewater” into a
resource growing food, beauty, and shade that builds community, and more
- How to create simple tools to read slope and water flow
- More than 450 illustrations and photographs
Praise for Rainwater Harvesting for Drylands and Beyond, Volume

“Brad Lancaster has written the definitive how-to guide for
harvesting rainwater. Much of this information has been near impossible
to find, and we owe Brad a huge debt for assembling it so lucidly. These
universal principles work not just in drylands, but in wetter climates
too. This is by far the best resource for designing and building
Earth-friendly, low-cost solutions to help us save our most precious
resource, water.”
–Toby Hemenway, author of “Gaia’s Garden: A Guide to Home-Scale
Permaculture”
“Everyone wants to ‘go green’ lately and, usually, the expression is
followed by a plug for a new product. Brad offers a shovel instead, and
directs you, literally, not figuratively, to your own back yard. We’ve
tried some of the methods explained in this book, and they work. Even if
you’re a lazy, mediocre, vagabond gardener, like we are, they still work.
And if you don’t take the time to understand every technical detail so
thoroughly outlined in this bible of rainwater– these methods still will
work.”
–Shay Salomon and Nigel Valdez, author and photographer, “Little House on
a Small Planet”
“Get out your shovels and dance in the rain! That is what Brad
Lancaster’s second volume in his trilogy on rainwater harvesting, will
make you want to do. This outstanding book provides an abundance of
well-documented ideas and tools for sustainable living in your watershed.
You don’t have to let wasteful, polluting large-scale water systems get
you downget out, get wet, and become a positive part of the hydrological
cycle!”

Volume 2 Foreword by Andy Lipkis
“G’day! How yur
tanks?”
This four-word greeting changed my life.
Twenty-one years ago while traveling up the east coast of Australia with
my wife and infant daughter, I noticed that nearly every conversation
between rural Australians began with this question.
Instead of the automatic, “How are you?” or “Nice weather,” it was a
specific question thatonce I figured out what it meantspoke volumes
about these people’s connections: to the land, to each other, and to the
environment.
Tanks, also known as cisterns, are the very large containers that store
captured rainwater and provide rural Australians with their life support:
vital water for drinking, bathing, and gardening. Many rely exclusively
on captured rainwater for all their needs.
This one question bundled and abbreviated a collection of concerns: How
is your water supply holding out? How has the rain treated you? How are
you doing in managing your land and water? How is your family holding up?
At what state of readiness do we need to be for our community
today?
Having spent much of my life working to awaken people’s awareness and
inspire them to take personal responsibility for the environment, I was
flabbergasted at the advanced state of consciousness being expressed by
these Aussies, and I saw in that awareness an answer to the water crisis
facing cities both in my native Los Angeles as well as in arid and
non-arid lands around the world.
And for that same reason, I congratulate and thank you for picking up
this book. You wouldn’t be reading this if you didn’t have an awareness
of the need to take responsibility and action either to secure your own
water supply or help solve the larger looming problems. Whether you are
in it for selfish or selfless reasons, you are a pioneer and taking on
the role of environmental healer. You are an early adapterbecause of
climate change and other issuesto a world that is already experiencing
ever-increasing water and energy issues.
Your experience, persistence, and success in this new wave of rainwater
harvesting may lead the way to wide-scale systemic adoption and
implementation in cities around the world.
Rainwater capture is transitioning from an individual act of personal
survival and self-reliance, to one that is replanting seeds of community,
interdependence, resilience, and sustainability.
The local and global world water situation is becoming urgent. As humans
in first world nations, our consumption and waste of natural resources is
generating sufficient pollution and depletion to damage and impair the
healthy functioning of nearly every natural system on earth. These
ecosystems are our life-support infrastructure for clean, abundant, and
safe water, as well as food, oxygen, and a stable climate. Reversing the
degradation requires a profound transformation of individual and communal
perspective and behavior.
Instead of believing that government and centralized systems are in
charge of the environment, we must shift to the other end of the spectrum
where individuals, families, households, neighborhoods, villages, and
towns take personal and collective responsibility and see that they are
the managers of the ecosystem and their natural life support systems. In
this emerging paradigm, government can and must provide information,
guidance, feedback, resources, incentives, and systems that enable people
to utilize their passion, compassion, creativity, and other energies to
help out on an ongoing basis.
If the issues above aren’t reason enough, it is important to realize that
harvesting rainwater is a crucial means of fighting global warming and
preparing our homes, families, neighborhoods, and communities for the
coming consequences.
As you read this book, you’ll find that rainwater harvesting practiced as
prescribed herein is really watershed and ecosystem stewardship. In
sculpting your landscape and creating water capture systems, you will be
restoring, revitalizing, or mimicking natural systems such as forest
watersheds; as such, you’ll be repairing the ecosystem and laying the
foundations of your community’s sustainability. And you will be a leader.
Any change you make on your home can become a demonstration and model
that othersyour neighbors, elected officials, or government agency
staffwill be able to study and copy.
As president of TreePeople, a nonprofit organization I founded 37 years
ago, I like to say that we are helping nature heal our cities. Our work
is to inspire people to take personal responsibility and participate in
making their cities sustainable urban environments. Our prime focus is to
support people in designing, planting, and caring for functioning
community forests in every neighborhood in Los Angeles (at the time of
this writing, one of the world’s least sustainable megacities).
Forests are natural sustainability infrastructure. Trees are THE basic
earthwork. Amongst other things, trees and forests, and the highly porous
and mulched soil beneath them, capture, slow, filter, store, and recycle
rainwater, and thereby recharge streams, groundwater aquifers, and
springs. They provide protection from droughts, floods, and
pollutioncleaning the water so it’s drinkable and usable. Trees and
forests sustain life. Unfortunately, when most cities were created, the
land’s original watershed functionality was unwittingly destroyed. The
idea behind functioning community forests is to plant trees and manage
the land in cities in a way that mimics natural forests, bringing water,
protection, and resources back to urban residents. However, since
urbanization has sealed so much of the land with buildings, roads, and
parking lots, simply planting trees and creating green spaces often isn’t
enough to make up for the lost watershed. By adding additional rainwater
harvesting technologies that are designed to mimic nature, such as
earthworksinfiltration pits, swales, and cisternsit is possible to
replace the watershed and ecosystem functions that were lost.
The magnitude of the water crisisand the opportunitybecame clear to me
in 1992, when the US Army Corps of Engineers proposed to spend half a
billion dollars to increase the capacity of the Los Angeles River by
raising the height of its concrete walls. The Corps determined that the
Los Angeles area had been so overpaved that, instead of soaking into the
ground, rainwater from a 100-year storm event would rush off all the
paved and sealed surfaces so quickly that it would overwhelm the river
and flood the nearby cities of southern L.A. County.
It was at that moment that the “How Yur Tanks?” lessons clicked for me. I
wondered how much of our 14.7 inches (373 mm) of average annual rainfall
we were throwing away each year, and whether we could use that half
billion dollars for cisterns to capture and use that precious rainwater,
just like the Australians. I asked the county’s flood control engineers
and they dismissed the idea, stating that replacing the river walls would
require installing a 20,000-gallon (75,800-liter) tank at each of one
million homesan expensive and impossible task. The local water supply
and stormwater quality agencies had similar responses to my questions.
The idea was too expensive for their individual missions and budgets and
would require what they all considered to be completely unacceptable
lifestyle changes on the part of the public. In the process of these
discussions, however, I learned that our average rainfall, if harvested
and used appropriately, could replace the portion of our imported water
that we use for landscape irrigationroughly half of the one billion
dollars worth of water the city of Los Angeles IMPORTED every
year.
What seemed impossible to the agencies was perfectly logical to me.
Having participated in design and deployment of LA City’s extraordinarily
successful curbside recycling program that now serves 750,000 households,
the magnitude of the task didn’t worry me. I researched and found out
that the separate water-related agencies had separate, unconnected plans
to spend a combined $20 billion in the next decade or so to upgrade or
repair their respective systems, yielding only “band-aids” with no
overall improvement in sustainability of the region.
So, I began designing a 20,000-gallon (75,800-liter) cistern that could
safely fit in a small urban yard without compromising anyone’s lifestyle
or posing any threat during our occasional earthquakes. It turned out to
be a modular 2-foot-wide, linear, recycled food-grade plastic tank that
could replace the fence or wall that separates most urban and suburban
residential properties. Further, I proposed to outfit all the tanks with
wireless remote-controlled valves and pumps that would enable flood
control, water supply, and stormwater quality officials to centrally
manage the multitude of independent tanks as one highly adaptable storage
network.
The networked mini-reservoirs could thereby perform at least triple
service for potentially less money than all the agencies’ separate
projects. By adapting all the areas’ landscapes to become functioning
community forest watersheds, my system was intended to produce multiple
additional benefits such as creating tens of thousands of new
green-collar jobs, saving copious amounts of electricity (by reducing air
conditioning needs with well-placed shade trees AND reducing the pumping
required to import water over the mountains into Los Angeles), reusing
all garden and landscape biomass and prunings on site as mulch, creating
a new local plastic recycling industry product and market, and creating a
disaster-resilient backup local water supply.
This was a lovely and compelling vision, but no one in an official
capacity took it seriously. I realized I’d need to do something to prove
that the idea was feasible, both technically and economically. That
notion turned into a six-year program of design, feasibility, and
cost-benefit analysis that became known as the T.R.E.E.S. Project
(Transagency Resources for Environmental and Economic Sustainability). It
involved hundreds of engineers, landscape and building architects,
foresters, scientists, and economists who collaborated to create a book
full of designs and specifications (Second Nature, TreePeople, 2000) to
retrofit or adapt every major land use in Los Angeles to function as
urban forest watersheds. Other team members spent two years conducting a
rigorous cost-benefit analysis. And finally, we built a demonstration
project, adapting a single-family home in South Los Angeles. The story of
the T.R.E.E.S. Project, including all of its major partners and
participants, is told at
www.treepeople.org/trees
.
The demonstration site, known as the Hall House (named for its owner,
Rozella Hall), had a relatively simple set of interconnected earthworks
designed to capture, clean, store, and use rainwater from a massive storm
event, and prevent any of the rainwater or biomass from leaving the
property and thus being wasted. We built berms around the lawns,
installed a mulched swale, put in a diversion drain to pick up driveway
runoff and carry it to a sand filter under the lawn, fabricated and
installed two modular 1,800-gallon (6,822-liter) fence-cisterns which
were fed by rooftop rain gutters through a filter, then connected to the
irrigation system, and finally, planted a trellis “green wall” of
climbing roses to shade and cool the house’s sun-heated south-facing
wall. We also removed 30% of the lawn and replaced the remaining turf
area with drought-tolerant grass.
Then, on a hot August day in 1998, we invited our agency partners,
numerous public works officials, and the news media to see the
demonstration house. We handed them umbrellas and unleashed a 1,500-year
flood event, pumping and spraying on that one house 4,000 gallons (15,160
liters) of water in ten minutes. Officials huddled in stunned silence as
they watched the water fall and flow, pooling in the bermed lawns and
cistern. They saw that none of the water flowed to the street and
stormdrain system. They saw how, in that one instant, their annual
billion-dollar burden of separate infrastructure systems and needs were
elegantly bundled and handled. The result: no stormwater pollution, no
street flooding, no greenwaste, dramatic water and energy savings, more
attractive landscape, and potentially thousands of new jobs.
The head of LA County Public Works’ flood control division couldn’t
contain his enthusiasm and proclaimed that the simple elegance meant this
demonstration could be easily replicated. A day later, after he and his
staff reviewed both our engineered designs and cost-benefit analysis, he
called me: “I’m sorry. We didn’t understand. We think you’ve cracked it.
Your idea needs to be deployed throughout the whole county, but it’s
going to cost more and take more time than you think. But despite that,
we need to begin scaling this up immediately. We’d like to try this idea
to solve one of the county’s most persistent urban flooding
problems.”
That was the beginning of the Sun Valley Watershed project, located in
the City of Los Angeles’ San Fernando Valley. After a successful two-year
feasibility study, the County Public Works Department launched a thorough
“stakeholder-led” watershed management planning and environmental impact
analysis. Six years later, both the plan and environmental report were
approved; construction of the first project began within a few weeks. The
plan calls for the retrofit of 20% to 40% of the watershed’s 8,000 homes,
and installation of a diverse network of earthworks. The earthworks mix
ranges from simple to complex, beginning with tree planting, pavement
removal, mulching, and berming. On the more complex end, the projects
will include installing street swales, and school watershed parks that
replace asphalt play yards with permeable greenspaces above large
underground infiltration systems and cisterns. Details of the Sun Valley
Watershed Plan, progress and planning process are available at
www.SunValleyWatershed.org
.
The Sun Valley Watershed planning process informed and transformed many
of the participating agencies and organizations and inspired others who
followed the process. For example, Los Angeles County Public Works formed
a new, integrated Watershed Management Division. The City of Los Angeles
Bureau of Sanitation launched and completed its first ever Integrated
Resources Plan for Water. And among several cities outside the Los
Angeles area, the City of Seattle initiated its Salmon Friendly Seattle
program, which seeks to restore viable salmon habitat throughout the
metropolitan area by revitalizing watershed and forest functionality in
all the city’s neighborhoods.
There are several keys to the projects’ successes so far:
1) we demonstrated that these adaptations represented acceptable and
attractive lifestyle changes that would be politically palatable;
2) we demonstrated with rigorous engineering that they were technically
feasible, safe, and capable of solving pressing problems;
3) we demonstrated that they were economically feasible by identifying
multiple outcomes and benefits that altogether would over time save money
for the assembled funding partners; and
4) we engaged and educated all the stakeholders from both the community
(including children) and relevant agencies.
This story is far from over. As it continues to unfold it presents a
variety of political, jurisdictional, and regulatory issues and problems
that we work to resolve. My initial vision was that so much water and
money could be saved by local governments that agencies would help
individuals and businesses cover the costs of installing and maintaining
the systems on their properties. That is now happening in some cities,
such as Santa Monica, Seattle, and Houston, that are giving grants for
cisterns and water-saving landscapes.
As we confront growing water-quality and supply issues, plus the
increased threat of flooding and weather-related calamities, it is
increasingly urgent that we find ways of adapting our homes,
neighborhoods, towns, and cities to become climate change and disaster
resilient. You have a huge role to play in protecting your household and
region by personally implementing some of the water-harvesting practices
detailed in this book. If you do this, and make yours a demonstration
project, you will help prove that it is feasible and attractive for your
region. You will make it more politically palatable, so your local
politicians can pass laws, change ordinances and codes, and make
resources available to help others implement on a wide scale. And then,
collectively, we just might tip the balance and put our nation on the
road to a healthy, just, and sustainable future.
Dig in and have fun.
