- Rainwater harvesting is the accumulating and storing, of rainwater. It has been used to provide drinking water, water for livestock, water for irrigation or to refill aquifers in a process called groundwater recharge.
- in dryland areas, which means formerly abandoned and degraded lands can be cultivated, and additional crops can be grown on small patches of irrigated land owing to better rain water retention (Pretty 1995; Reij 1996), and improving water productivity of crops (Morison et al. 2008).
- Collection of both runoff and rainwater for various purposes, such as irrigation or fountains.
- try: make an effort or attempt; “He tried to shake off his fears”; “The infant had essayed a few wobbly steps”; “The police attempted to stop the thief”; “He sought to improve himself”; “She always seeks to do good in the world”
- an analytic or interpretive literary composition
- An attempt or effort
- A short piece of writing on a particular subject
- A trial design of a postage stamp yet to be accepted
- a tentative attempt
- A large or overwhelming quantity of things that fall or descend
- precipitate as rain; “If it rains much more, we can expect some flooding”
- Moisture condensed from the atmosphere that falls visibly in separate drops
- water falling in drops from vapor condensed in the atmosphere
- drops of fresh water that fall as precipitation from clouds
- Falls of rain
rain water harvesting essay – Rainwater Harvesting
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 225 illustrations and photographs

rain water harvesting essay
These instructions also explain how to lower your water consumption by pointing to internationally acclaimed water conservation products, and showing how to offset your use of publicly treated water with a home constructed DIY cistern system that uses harvested rainwater as a supplementary water source.
With over 58 illustrations, example calculations, and tabular rainfall references , these instructions explain how to identify how big your cistern should be and how much water you can realistically expect to harvest.
Starting with one rain barrel and adding to it in a methodical manner, your rain harvesting can grow from a simple garden supplement to a large reservoir that can supply a significant amount of water for your garden, lawn, and non-potable water needs. Like a rain barrel on steroids, this simple approach recovers usable rain water instead of watching it run down the drain.
