Storage Type & Location:
Rainwater harvesting storage is located above ground, below ground, or
partially buried. In deciding what storage is best for you, the key
factors are cost and aesthetics. Other factors such as grade, allocated
space, and underground geology can be a factor as well.
Above ground tanks require the least amount of excavation which can
reduce costs dramatically. These can be hidden behind trees or placed
away from the home. Many people also use quality above ground tanks as
features that complement their landscape design.
Partially buried is a variation in the installation of above-ground
tanks, where the tank is placed slightly in the ground, usually going a
quarter to halfway up the tank.
Generally, in-ground tanks require a larger footprint. Excavation costs
can be significantly increased when rock is encountered. In-ground tanks
vary in their load-bearing capacity from riding lawn mowers to cars to
semi-trucks. Because it allows the ability to use the space, this is an
attractive option for many rain harvesters.
Note that precast concrete tanks are limited in size and poured concrete
tanks are obsolete. If used, concrete tanks should be coated on the
inside to protect against deterioration caused by the slightly lower
P.H. of rainwater. These tanks are not suitable for potable water.
Therefore, we highly recommend that all installations should be consider
throughoutly. Your system can be much more efficient and cost less by
this method.
For Residential Area:
Harvesting in residential area usually range from small to medium due to
need and financial capacity. There is no need of a big and costly
collecting system. We recomend these following products:
Common vessels used for very small-scale water storage in developing
countries include plastic bowls and buckets, jerry cans, clay or ceramic
jars, cement jars, old oil drums, empty food containers, etc. For larger
quantity a polyethylene tank will do just fine, you can also consider a
low profile plastic tank.
Pumps in this area is usually the 1 pump type, but you can also consider
a 2 pump one. Controller doesn't need to be
complicated, just simple buttons and high safety.
Filter can vary based on use, for irrigation, flushing toilet or washing
cars, you just need a basic one to clear out harvested water. To fit for
any potable need you will need to spend little or more on some devices,
choose wisely.
For Commercial Area:
Commercial area harvesting rarely appear in a small range, for long term
purpos high durability products are selected:
An underground system is the most suitable for this area, choose a
durable tanks like polyethylene, fiberglass,
bolted−steel or modular storage, which is the most
used in commercial applications.
A 2 pump type is require for water to reach its place, controller must
be able to control all system and safe, filter can vary.
