"Rain water harvesting"

Download file to see previous pages The rainwater harvesting systems involves three main elements that are collection system, conveyance and storage system. The type of harvesting system rely on the magnitude as well as the nature of the catchment area. Simple roof water catchment is one of the collection systems used in many households whereby cistern, pipe and appurtenances are the materials used in roof water collection system. Second is the large systems that are made for the large institutions such as stadiums, schools among other facilities. The system appears complex as ground and roof water is preserved in underground reservoirs. Roof water systems for the higher buildings are another rainwater harvesting technique. In this system, roof water is often designed for collecting rainwater and the water is stored in a different cistern. Land surface catchments are regarded as the simplest way of harvesting runoff water as compared to rooftop catchment. Lastly, is the collection of storm water in urban areas whereby the storm water is subjected to various contaminants? In this catchment, maintaining the catchment clean is the central aim of the system and thus it entails consideration of water pollution control.The collection of the rainwater using gutters is determined by the material used in water harvesting that can affect the efficiency of the system. For example, the low-pitched roofs do not lose much water like steep-pitched roofs. The materials used in water harvesting and the location of the storage facility affect the efficiency of the system operation. ...Download file to see next pagesRead More

Organ Harvesting
...Organ Harvesting Organ harvesting refers to the practice of removing usable organs from someone who is dead so that they can be transplanted into someone else. There is some dispute over the proper term for this procedure, since it involves delicate ethical and personal issues for many individuals. Some people may prefer the term “organ donation,” which indicates that the organs were willingly surrendered to benefit other people (What is Organ Harvesting?) Organ harvesting or organ trading is a controversial topic because of the serious ethical issues involved in it. Medical science has recently succeeded in replacing defective kidney and heart like human organs with...

Energy Harvesting
...(Golding, 1976). Energy harvested from the wind largely depends on siting of the wind farm. 2.3 Hydroelectric Hydroelectric systems create energy by harvesting energy by force of water. Water is collected in a dam or a reservoir. The water near the bottom of the reservoir is forced by the pressure of the water above it to be channelized with great kinetic energy. Furthermore, the gravitational potential energy adds up to this energy as the water falls from a height. This water is fed to the turbine. The kinetic and potential energy of this water is used to turn a turbine. The turbine...

Almond Harvesting
...Almond Harvesting What are Almonds? Almonds are essentially stone fruit that are normally eaten as nuts. Almonds are seen to grow inside the inedible fruits produce by the almond tree and are closely related to plums and peach. An almond’s composition and growth has often been likened to that of a peach pit. The climatic condition of most of the counties in the United States is seen to be quite unsuitable for almond production and California is perceived to be one of the few states in the country that has a suitable enough climate where these trees are able to thrive and the only state in which they are commercially grown (UC. College of agriculture 174). Harvesting Almond Orchards in the United States...

Roof Rain Water Harvesting
...Water Engineering - Rain Water Harvesting Introduction Roof top rainwater harvesting refers to the process of collecting, conveying, storing and distributing the natural water for various non-potable applications. The objectives of such type of installations are to compensate for the reduction in the volume of water due to large scale building construction process. As the construction of car park requires large area of covered space it could limit the infiltration of rainwater which other wise would have infiltrated into the ground and enriched the prevailing ground water table. The various applications...

Acid rain
...The Month Acid Rain People’s economic activity in the 20th century caused serious pollution of the planet with various waste products. The air basin, water, and soil in the areas of large industrial centers often contain toxic substances that significantly exceed the permissible level. In the recent decades, environmental contamination and the breakouts of related diseases have become more common. To describe this phenomenon, experts and media began to use the term “environmental crisis” (Mangun and Henning xii). The global environmental crisis is the result of the complex industrial and agricultural activities of modern civilization. It appears to change the characteristics of the environment on a...

Analyse the impact of implementing rain water harvesting systems on the stormwater system
...a great impact on both the vegetation and the organism within the ecosystem. This report, therefore, analyzes the impact of rainwater harvesting systems such as cisterns and rain barrels on stormwater as a solution to help reduce the volume of stormwater runoff and prevention of pollution to the existing stormwater. The basic components of residential and small commercial scales are; gutters and downspouts, catchment surface (roof), storage tanks, delivery systems, and water treatment for portable systems (Texas water development board 2005). Field observation is an integral part in the analysis. In analysis, identifying indicators can help in measuring the efficiency...

Acid rain
...ACID RAIN Acid Rain Acid rain is defined by Kumar as a term used to de "Any precipitation which has a value less than 5.6,the PH of uncontaminated water".1 In most cases, Kumar notes that acid rain falls under a PH of between 5.6 and 3.5.2 It is important to note that evidence of acidic precipitation appears after a few days and long distances from the origin. Acid rain can be prevented through a number of ways in future. According to Casper, acid rain can be prevented in future is by switching to sources of energy that emit low levels of carbon.3 Combustion of fossil fuels is considered one of the major causes of acid...

...technology to ensure the water is safe for human consumption (JFC n.p.). The availability of different sizes makes the system ideal for areas without water security. The installation process is cost efficient as the tank can be backfilled with pea-gravel instead of backfill. Furthermore, the assembling of the tank can take place on-site, and the assembly instructions provided eliminating the costs of hiring a crane. The Stormsaver provides high-quality rain harvesting systems at competitive prices. It provides its services for domestic and commercial use. Testimonials from users of the system argue that the installation has halved their water bill, and...

Rainwater Harvesting
...Rainwater Harvesting Introduction Rainwater harvesting is a technology that is used to collect rainwater from hard surfaces in response to water scarcity. The water is collected on surfaces such as rooftops and stored in home-made barrels or large underground reservoirs for later use in domestic consumption or farm irrigation. Rainwater Water is harvested in many regions due to variability in rainy season where some areas receive a minimal amount of rain that makes the practice crucial. The water is harvested using pots, jars and engineered technologies such as using pipes to direct...
