Rainwater Harvesting: Solution to Water Shortages

Home » Blog » Rainwater Harvesting: Solution to Water Shortages

Fresh water is scarce in most parts of the world. When freshwater supply is available, the cost is prohibitive.    

This necessitates the need to collect and store every bit of rainwater that is available. A good installation will be operational for months or years with little to no maintenance. A cost-benefit analysis for that entire time will show that the value from such an installation far exceeds that of the costs. Therefore, for maximum economic advantage, proper collection systems and adequate storage capacities need to be installed. 

Rainwater has the properties of being free from most minerals unlike water from ground sources such as boreholes. The ever-rising population in urban areas and the inefficiencies of water distribution are common. These might lead to water shortages in domestic settings. An emphasis on rainwater collection will undoubtedly save the urban dweller from the costs involved with municipal water sources. Furthermore, the usual uncertainty that comes with the provision of municipal sources means that a better means of securing potable water is always welcome. 

Rainwater Harvesting will save you money!

Investing in a good rainwater harvesting technology will not only give you some of the best quality water but also save your hard-earned cash on this precious resource. Below are some of the major pros of a harvesting system. Also listed are any possible limitations to a harvesting system.

Major Pros of Rainwater Harvesting

The major advantage of considering the rainwater resource is its quality. Rainwater is naturally of high quality. However, there might be exceptions in areas where some sources of air contamination are present such as factories that release pollutants into the air. Active volcanic activities that discharge into the air might also decrease the quality of rainwater. However, these pollutants are often rapidly dispersed in the air and don’t tend to last too long. Some groundwater sources often exhibit great quantities of toxic minerals such as arsenic, a factor that is rare in rainwater sources.

The independence of rainwater as a source of freshwater makes it appropriate for homesteads and units that might be far from each other. Unlike piping, this independence reduces the setup costs and increases the physical ranges of installations. 

The installation of the necessary collection systems can vary from affordable materials to more expensive ones. Local materials and labor can also be applied.

Once the initial setup of the system is attained, no energy is required for the subsequent operations. A system that is installed using quality materials may easily run for several months and years with little to no maintenance whatsoever.

Unlike other systems, rainfall collection technology is often easy and can be readily performed by the user. These can include minor tweaks to the system to make it as efficient as possible. 

Disadvantages of Rainwater Collection

An installation of a rainwater system might be cost-prohibitive especially due to the relatively expensive prices of the required units. However, this cost is often only limited to the capital aspect of the entire process. 

While high volumes of precipitation might be experienced, the resultant amount of water collected might not be satisfactory if the area of the roofing is not satisfactory. Furthermore, a limited amount of rainfall to a catchment area might mean that the collection system does not perform its intended use.

The purity of rainwater means that it lacks the mineral components usually present in other sources such as spring water. The mineral-rich water is highly popular due to its alluring palatability and perceived health value. A source lacking in these essential nutrients might not be suitable to people already partaking in foods having low levels of such elements. 

These cons do not represent the situation in many environments and the advantages of exploring a good rainwater harvesting system outweigh the limitations. 

Roof Harvesting Technology can help you conserve water!

The main method of securing rainwater is through the use of Roof Harvesting Technology. The system generally involves the collection of rainwater that lands on the roofing material of a building. The water is consequently stored in suitable storage facilities such as tanks. The storage material must be properly waterproof to ensure that the water is available throughout the year. In other instances, the rainwater collected comes handy during drought periods. 

The rainfall storage varies depending on the need, intended use, the environment, and available resources among other factors. The water might be stored in sumps or wells dug entirely to serve this purpose. In areas of high elevations, the water can be utilized as a means of recharging aquifers. 

Rainwater from roofs is increasing in popularity in hilly regions where springs were predominantly used in the past. The quantity of water from such sources is increasingly becoming too low to supply the needed water demands. This might be the result of deforestation and the ever-increasing demands.

To establish a rainwater collection system in your household, you need five key components including a filer, storage tank, and gutter.
