how can we harvest rain water??
what are the major components of the rain water harvesting system
do we need a permit??
people have been harvesting rain water for 1000's of year. It is a clean cheap and easy way to supple water to plants, animal and people drinking water
There are different types of rainwater systems on the market. Large and small from small collectors in the garden
to domestic storage for a house, we can also get large storage tanks such things as offices or schools. There are two different types of systems,
Direct systems and Gravity rainwater systems. We will start with the direct system first.
Direct
The Direct System, the rainwater is pumped directly to the draw off from the rainwater storage tank. When the storage water tank is running dry there is a small automatic charge. Main water is then feed into the storage tank or into a unit, to ensure the system never runs dry. The main advantage of this system is that rainwater is delivered to the appliances at main pressure.
Gravity
Gravity system has a reserved stored water tank in the event of any problems with the main water supply. The gravity system requires a header tank in the attic space the water from the
header tank will then flow by the means of gravity to the appliances The system will always draw from the rainwater supply first, before switching over to main water in the event of there being no
rainwater in the storage tank.
Direct Rainwater
when rainwater runs off your roof system and in to a gutter it follows down to a storage tank of some kind aka cistern, rain barrels or even a pond, which can be reused
What are some pros and cons??
Pros
-free water
-takes load of the municipality
-stop run off
-dose not require alot of upkeep
-low to no coast to run
-stops or slows flooding
Cons
-high coast to install large systems
-water that could of gone back in to the water supply
-water is not safe to drink if filter is not added
how much does it cost $?
Anywhere from 200$ for a home made system up to 100,000 $ for a large commercial system but typically 3,000 -10,000$ for a single family home.
odds are you have harvested water in some way before, and didn't know that you were.
what is xeriscaping??
Xeriscaping refer to landscaping and gardening in ways that reduce or eliminate the need for supplemental water from irrigation. It is promoted in regions that do not have easily accessible, plentiful, or reliable supplies of fresh water, and is gaining acceptance in other areas as climate patterns shift. Although xeriscaping may be an alternative to various types of traditional gardening,
storage tank
are built to hold large amounts of water for a period of time well not being used. they can hold anywhere from 1000 liters to 300,000 for bigger buildings such as school or offices. they can be placed above ground or below, but it is best to be stored under ground because it will stay cool and dark, which will stop any growth of bacteria.
Filtration
the filtration is important part of the system because everything will go through the filter before it passes into the the storage tank. the filter is responsible for blocking any debris, or dirt particles that is passed through with the rain water, giving clean water into the tank.
pump set
the pump will draw water into the tank with a float filter, which will be pumped to all the outlets in the property, and the pump must always be protected from dry running or it will wear it self out and stop working.
permits are need for all types of system, all storage tanks need to meet plumping code and must be far way from any sewage
who can i call to install a system??

what strategies can i use in a landscape
water can be stored in landscapes too, from ground water, rain barrels that look a like pots to a small or lager pond. This also a type of storage tank for the water. This water can be used at any time and is a great way to stop run off and flooding
what type of plants materials are best for my system
plant life well take water way from your system and or damage it, using the right plant and right soil that will not need to alot of water to produce or grow will increase the amount of water that will gather. Also using sand or rock under your lawn insure fast and easy drainage.
alternative methods
rainwater can be used for a lot of different system. we can cut coast inside and out side of the house. inside we can wash are landry, flush or toilets and wash are dishes with it even take a shower. outside we can use rain barrels to water are lawns, wash are cars, water the plants all for little to no coast
