Essay On Rainwater Harvesting

INTRODUCTION
It is widely known that water covers up to 70% of our planet's surface. However, we have never
been able to have enough fresh water to meet our demands. Up until now, 1.1 billion people
worldwide still lack the access to usable water sources and a total of 2.7 billion find water scarce
for at least one month of the year. (WWF) Even in a centralized industry area, the main water supply
system sometimes not able to meet the demand.
Water crisis is now a global problem. Since the 1950s till this present date the population of world
has increased into double. The use of water is increasing but the sources are constant for safe
water. The world is facing an overall of deficit of fresh water. Therefore, the need to find an
additional water resource is inevitable.

ADVANTAGES AND DISADVANTAGES OF THE PROJECT
In times of such crisis today, rainwater harvest is indeed a blessing. However, there is no perfect
solution for a reality problem.
Below we are going to highlight some advantage and disadvantages of rainwater harvesting.
Advantage
1.Rain water harvest relieves pressure on other water sources. In a small community such in rural or
mountain area, rainwater supply can co–exist with other sources and can act as a supplement to
them. (CEF, 2013)
2.Safe, drinkable reserved rainwater can be the solution when there is a calamity or an outbreak of
safe water. It can help us prevent many diseases and epidemic to spread wide during water crises due
to the use of unclean, contaminated water.
3.Storing excess rain water during rainy season can help reduce the possibility of. Drainage
overload can also be prevented by keeping drinkable fresh water from the rainwater. Furthermore,
water from flood can also be well taken care of and utilized by the rain harvesting system.(GDRC,
2015)
4.It can help reduce soil erosion during rainy

Rainwater Harvesting: Conserving Water at DHS
Decatur High School uses water for numerous tasks on a daily basis. Whether its watering schools
lawns, washing animals at the Ag building, watering greenhouse plants, or cooking in the cafeteria
and washing one's hands; DHS could not function without the readily available supply of water.
Unfortunately, water has become scarcer in Texas over the past few years, because of extreme
drought conditions. Due to the limited supply of water in Wise County and surrounding areas,
DHS should install a rainwater harvesting system. People often take water for granted, assuming
that it will always be readily available. They see endless pictures of beautiful lakes, rivers, and
oceans that have an abundance of crystal clear water on websites such as...show more content...
In the same way, Georgia Tech created a 6000–gallon collection system that waters landscape and
allows over flow to travel to a nearby pond ("Old Civil"). These two schools are merely examples
of the hundreds of schools seeking to make a positive impact on their environment. At CHRIS Kids,
a foster care system in Atlanta, Georgia, a 19,400–gallon collection tank was built to provide water
for irrigation. Property manager Harold Moreau stated "We use those gallons of water for our
irrigation. The property has a lot of natural vegetation, and with the readily available source of
water from the cistern, we're able to water accordingly as well as reduce costs, because we're not
taking in any city water to use for our irrigation program"("CHRIS Kids"). Building a proper
rainwater system can be rather expensive upfront; however, many organizations offer funding to
assist with the cost and in the long run, the benefits will outweigh the cost that was spent to build
it. According to the Texas Water Development Board, a typical collection system for a home will
cost between eight to ten thousand dollars ("Frequently Asked Questions"). While this sounds like
an outrageous price to collect a small amount of water, systems can actually collect a lot of water
from only a little amount of rain. The average rainfall in Austin is 32 inches annually, but homes
can collect up to 34,000 gallons of water per year ("Frequently Asked

The list below are some creative and innovative solutions to water scarcity. Very basic technology,
such as rainwater collection, water filtration, building wells and water desalination can be some
solutions, but they are not included in this list, as it is already very common and many countries

PUR Packets (for cities/towns with contaminated water) The PUR packet is a small pack of
powder that can quickly turn 10 liters of dirty water to clean and drinkable water. Developed by
P&G and the U.S. Centers for Disease Control and Prevention (CDC), the PUR packet removes
pathogenic microorganisms and suspended matter, making previously contaminated water clean.

Collector (for cities/towns with lack of water) Lima, Peru is one of the driest places on Earth and
over 700,000 people have no access to clean water. However, Lima's atmospheric humidity is over
90 percent. Therefore, Peru's University of Engineering and Technology (UTEC) thought of a way to
turn the humid air into clean and drinkable water. They built a humidity–collecting billboard in the
Bujama District of Lima. Electricity from the city's power lines runs the five condensers inside the
billboard. When air contacts the cooled surfaces of the condensers, the air also cools, and the water
vapor in the air condenses into liquid water. After

Rainwater harvesting is the accumulating and storing of rainwater for reuse before it reaches the
aquifer. It has been used to provide drinking water, water for livestock, water for irrigation, as well as
other typical uses. Rainwater collected from the roofs of houses and local institutions can make an
important contribution to the availability of drinking water. See also first flush. Contents [show] |

1.1BACKGROUND
Rainwater harvesting system (RWHS) is a direct collection of water from roofs and other purpose
built catchments. It is also as the collection of sheet runoff from a made–man ground or natural
surface catchments and rock catchments for domestic, industry, agriculture and environmental use
(Abdul Hamid & Nordin, 2011). Normally, RWHS is depended to the size of the roof catchment
area and the available rainfall. RWHS usually have six components. There are the catchment area,
gutter and downspout, a filtration system, a storage system, a delivery system and a treatment
system. According to (M. Martim & W. Watkins, Jr, 2010, pp. 2000

The government is trying to promote the application of RWH systems in buildings, houses, mosques
and others. Therefore, the RWH systems are not considered as a new phenomenon.
The RWH systems apply an environmental friendly design. People throughout Malaysia lack enough
knowledge of knowing the benefits RWH systems. Within the support and effort of government in
promoting the application of RWH systems, the numbers of buildings and others using the RWH
systems increased.
The establishment of National Hydraulic Research Institute of Malaysia (NAHRIM) make people
aware to study how the importance of RWH systems actually. Based on NAHRIM, approximately
RWH systems begun implemented during of drought crisis in 1998 which brought unpleasant water
supply disruptions for Klang Valley folks.
Although, the application is still ongoing, the implementation of RWH systems in building offices
not widely use. This implementation is executed more on green building offices. From these
circumstances, it seems like RWH systems only competence to the green buildings because RWH
systems is non environmental impact and it design for green. Here, we will look how far
differences of efficiency RWH System between green building and non green building on this study.
Besides, RWH systems are described as water and energy efficiency that had further explained in

How To Write A Fog Harvesting Essay
Water is the biggest necessity for all humans to have on this earth. Every person needs water in
their body to be able to live. Other than drinking, water has many more uses that people take
advantage of. It is used for cooling machinery, it can be used as a source of power, to water crops,
and much more. Unfortunately, not everybody has access to a stable water source. Right now,
several states such as California, Nevada, and Oregon have severe drought. Many people are
unable to use a toilet because they don't have the amount of water needed to flush it. In fact, 1.6
million people in America don't have any sort of access to indoor plumbing at all.. Seeing how big
of a problem it is, many states have already taken action through various methods to obtain more
water. More operations have begun to obtain more water from different sources, and many states
have employed methods to clean dirty water and give it to the people. Despite these efforts, the
reality is that there are still too many people without access to water, and the level of drought that
some of our states have is too much. There is one method that has been used within a minor scale in
some other countries that requires some more attention, which is called fog harvesting. Fog
harvesting is a method that should be used much more in areas that lack water because it is
environmentally friendly, is easy to construct, requires no constant attention or care, and it simply
provides a great amount of water. As shown

Rainwater Harvesting
Introduction:
In today's world, the scarcity of water due to global warming and climate changes is a major
problem. This cannot be reduced just by introducing water restrictions, it is necessary to collect and
store water in order to use them during droughts and situations where the supply of water is limited.
For this purpose, many cities have decided to build rainwater harvesting tanks in order to collect and
store rainwater for future use.
Rainwater can be used in various ways including watering gardens, toilet flushes, household chores
etc. Though, it is not advisable to drink rainwater, it can still be used for cooking after being boiled
or cleansed.
This report will include investigating several things such as the sizes of the tanks required for a
certain volume of water, the volume of water that should be used during different times of the year
and so on.
Through this task, common questions like– What is the capacity of rainfall that my roof can catch?
How often does rainfall occur? / What is the average rainfall in my area? What dimensions of the
tank would I need, to save a certain amount of water? How much water would I need for a certain
period of time? Would be answered
Answers
To prove: 1mm of rain that falls on 1m2 of surface = 1 litre of water in the tank.
L.H.S= 1 mm of rain on 1m2 of surface
Volume/ Capacity = h*A
= 1mm * 1m2
= 0.001m * 1m2 (Since 1mm= 0.001m)
= 0.001m3
1m3 = 1000 litre

Rainwater collection can help minimize the demand for water that gardening makes during the
hottest, driest periods. Rain barrels are a great way to capitalize on this free source of water.
Reasonably priced and easy to install, gardeners are advised to take a look at utilizing rain
barrels. Rainwater collection for use during dry spells is not new technology; rainwater has been
being collected for over 2,000 years. This ancient technology has found new life among today 's
green gardeners. Costs of municipal water are rising and drought restrictions now face many areas
of the United States. While the average American may not be inclined to install a large cistern in
their yard, rain barrels provide a reasonably priced and easily installed option that produces a nice
supplement to traditional water sources. Water is a much valued and often taken for granted natural
resource. Water is essential to life, human, critter, plant and other. Many Americans turn on the tap,
leave it running for whatever their intended purpose, such as brushing one 's teeth, and never give a
thought to the big picture of water shortages around the world. Often gardeners turn on their
sprinklers with not much thought beyond their knowledge that their plants need a thorough
soaking. It may seem to some that water is in abundance. Lakes and rivers may dot the topo map
of your region. However, consider these facts. Though 70% of the Earth surface is water only 2.5%

Advantages And Disadvantages Of Rooftops
In Cairo, Manshiet Nasser is a prime location for Zabbaleen which are local collectors of garbage.
They are supposed to recycle the city's waste and they recycle as much as 80% of the collected
refuse (Simpson, 2016). Most of the rooftops at this area is used as a space for storing, segregating
garbage, and processing Garbage where it is considered as a valuable resource of income and
business. Residence and work areas are attached to one another.
In downtown Cairo, Zamalek, and some other areas. Many rooftops are used as residence
especially in the areas where the buildings' rooftops do have previously service rooms for drivers
and maids' Focusing more on such areas, it's also considered as suitable living areas(s) for many
families that couldn't find the suitable homes, especially with the shortage of housing units. Having
these rooftops with basic conditions of living standards, prime location among the city, is not a bad
idea to be hosting many residents.

5.1. Green roof definition.
A green roof is defined as a living roof at the top of a building which is either partly or totally
covered with vegetation and a growing medium and underneath it is a strong and water resistant
membrane. Some additional layers are sometimes included in it as well like root barrier along with
a system of irrigation and drainage. Plants are grown on the top of the roofs and this helps in the
replacement of vegetated footprints which were lost while constructing the

In 2012, Campisano and Modica created a dimensionless methodology for the best design of
domestic rainwater harvest systems. From these studies, it can be proved that the previous research
had poorly designed the intake of the rainwater harvest systems. The size of the designs of rainwater
harvest systems were kept in small communities. They also lacked consideration of all metropolitan
catchments varying in special capacity and quality of the systems. The second category in rainwater
harvest systems is simulation and evaluation of the effectiveness. First the research included
evaluating the possible potential for safe to drink water savings by using rainwater in residential
areas. The second thing that was in the research was estimating nonpotable household potential. With
the performance of storage type, and investigating the potential benefits from sharing rainwater
harvest systems with neighbors by using rainfall data. Establishing the probabilistic relationships
between storage capacities and deficit rates of rainwater harvest systems was some of the next things
that were used to consideration. These studies weren't really considered for the surface and sewer
flowing after rainwater. There are many studies evaluating the performance and reliability if

Why Is Tap Water Better Than Rainwater
Rainwater and Tap Water
For many years, commoners debated whether tap water or rainwater is better for the growth of
plants. These waters have different levels of salinity and different PH levels. The higher level of
the salinity, the lower chance of plant growth and vise versa . The lower level of the salinity, the
higher chance of plant growth. Also the lower PH level, the higher chance of plant growth. The
higher PH level, the lower chance of plant growth. Rainwater is better for the plant's growth due to
the lower level of salinity and the lower level of PH.
According to Freshly Squeezed Water (1), an organization that fits filtration systems in homes and
businesses, tap water contains more salinity than rainwater (FreshlySqueezedWater 1). Salinity is not
good from plants because it can absorbs the plant's water which can be very harmful to its growth.
Tap water also contains arsenic, radium, aluminum, copper, lead, mercury, cadmium, and fluoride.
Fluoride can build up in the plant's tissues which can lead to defects in photosynthesis. Due to the
fluoride within the water, tap water is not a good choice for plants. Also many...show more content...
Ken Rubin 1). Acid rain is rainfall that contains acid from atmospheric pollution. The amount of acid
in rainfall differs from where the rainfall is from. Dr.Ken Rubin wrote on how acid rain affects
plants. Acid rain affects plants differently due to the makeup of the plant's tissues and the makeup
of the soil. This effect is neither good nor bad depending on the makeup of the plant and the soil.
Dr.Ken also stated that the excess acid in soil can dissolve soil substrate, leading to erosion. This is
very harmful to the growth of the plant's because erosion can lead to the absence of nutrient within
the soil. Rainwater can have a harmful effect on the growth of the plant due to acid

Components of the roof top rainwater harvesting system
The illustrative design of the basic components of roof top rainwater harvesting system is given in
the following typical schematic diagram/
The system mainly constitutes of following sub components:
В§ Catchment
В§ Transportation
В§ First flush
В§ Filter
The surface that receives rainfall directly is the catchment of rainwater harvesting system. It may be
terrace, courtyard, or paved or unpaved open ground. The terrace may be flat RCC/stone roof or
sloping roof. Therefore the catchment is the area, which actually contributes rainwater to the
harvesting system.
Transportation
Rainwater from rooftop should be carried through down take water pipes or drains to storage
/harvesting system. Water pipes should be UV resistant (ISI HDPE/PVC pipes) of required capacity.

Water from sloping roofs could be caught through gutters and down take pipe. At terraces, mouth of
the each drain should have wire mesh to restrict floating material.
First Flush
First flush is a device used to flush off the water received in first shower. The first shower of rains
needs to be flushed–off to avoid contaminating storable/rechargeable water by the probable
contaminants of the atmosphere and the catchment roof. It

Stormwater Harvesting
Stormwater Harvesting projects typically cost millions of dollars. With the larger the scale of the
scheme, the larger the costs of funding, but in return millions of litres of water can potentially be
saved annually [4]. Having said that, there are still millions of dollars invested into unprecedented
pilot projects which inevitably become invaluable learning opportunities to determine which means
can be utilised best as being the most cost–effective. Developing successful Stormwater Harvesting
schemes are reliant upon pilot projects which can provide specific guidance by means of producing
new ideas and principles. However, there are a few constant elements that are generally common in
all Stormwater Harvesting schemes developed, which will be discussed below.
In a typical Stormwater Harvesting scheme, there are several stages that are critical to the process.
Unlike basic "Rainwater Harvesting", which simply involves collecting the water runoffs from roofs,
Stormwater Harvesting incorporates several common elements across the varying methods which
include the collection (harvesting) of runoff water from drains, treatment, storage and distribution
into urban areas [1].
Harvest
Stormwater is harvested from a water source (e.g. drain).
If the source is owned by a private owner or government body sector, a licence will need to be
attained.
Treatment
The harvested stormwater is treated to a water quality level that is

The Pros
What are the pros and cons of such an approach from the perspective of various stakeholders? The
pros from such a law would be that people would not be exposed to such dangerous products.
Consequently, symptoms such as nauseas, vomiting, or cancer would lower among people because
they would not be a result of these products. Another pro is that the environment would be safer
throughout the world if the products were to be banned in other countries as well. Also the fact that
Amvac would not be sued anymore because it would not sell such dangerous products. The fact that
several animals would have the insects that were being killed back in their food chain.
The Cons
If the United States was the only country to ban these products, one of the cons would be that it is
not ethical to sell these dangerous products to another country. Another con would be that the

The Importance of Rainwater Producing
Rainwater producing is the accumulation and deposition of rainwater for reuse beforehand that up to
groundwater. Also, is a method of collection and storage of rain water in external (reservoirs) or
groundwater below the external of the earth beforehand you become capitulated as external runoff.
Architects and builders are nowadays routinely constructing arrangements to make sure we uphold
water stocks. A little of the arrangements most oftentimes installed at the nowadays are those
projected for rainwater harvesting. In easy words, this has been projected to arrest and storage
rainwater that falls on the external in order to be reused in the houses and in the business.
Uses contain water of the park, water for livestock, indoor warming of the residences and water for
irrigation intentions etc. Rainwater that has been amassed of the surfaces of houses, tents and innate
institutions, or from specially coordinated spans of earth, might make an vital contribution to
drinking water.( Anon, 2009 )
It is a style to rise the nutrition of groundwater across storage rainwater innately, by rooftop water
producing, packaged to engraved wells (Thompson,2010 ). From the main goals of rainwater
producing is:
Supplement internal water needs.
To face the producing demand from water
To amass rainwater.
To supply water to garden.
To craft awareness concerning rainwater producing system.
