Water Harvesting Solutions
Commercial buildings can save millions of gallons of potable water each year by harvesting rainwater, greywater, stormwater, and condensate for non-potable applications such as toilet flushing, irrigation, and cooling tower make-up. Wahaso provides complete design/build water harvesting solutions services, consulting with engineers to determine the best strategy for a project and fabricating a fully integrated system.
The FEMP identifies rainwater as a legitimate water source and recommends it for people who cannot access municipal water. Harvesting rainwater is a suitable alternative way of fulfilling all your water needs. We recommend that you explore as many options as necessary so you can use them for more applications around the home without paying any extra bills.
People in arid regions do not have a choice but to harvest rainwater. However, you would be surprised to learn that even people living in apartments and townhouses still prefer to use it to complement their primary water supply system. The practise of rainwater harvesting has gained a lot of traction over the years, and technology continues to evolve so that the water is cleaner, fresher and suitable for multiple applications around the home.
FAQ Harvesting Rainwater
How Safe Is The Water?
In theory, rainwater should be safe to drink. Many of us enjoyed playing in the rain during childhood and did not develop any issue from drinking it straight from the sky, even if it did not pass through prior filtration or treatment.
It is not recommended that you drink it, especially if you are harvesting it from the roof, because the water has come into contact with contaminants from the surface and may develop harmful bacteria if it sits in the storage tank for too long. Rainwater in urban areas has more contamination, such as smog, dust, bird poop, and dust looming in the air and on surfaces. The better way around this is to run the water through a filtration system, to remove the visible solid material and the more minor elements that are just as harmful.
Treatment After The Rainwater Harvesting Process
The more traditional way of treating rainwater is to boil it after passing it through a sieve. The more professional way is to pass it through several filters to eliminate all kinds of compositions depending on what surfaces it passes through. Some common ways of treating the water include:
- Revere osmosis to reduce the number of solid sediments
- UV purification to kill waterborne organisms like viruses and bacteria
- Carbon filtration to get rid of unwanted chemicals
Boiling your rainwater will not do much but kill the live organisms and also transform the chemicals into more intense compositions.
Legality Of A Rainwater Harvesting System
It is not always legal to harvest rainwater, but many counties and municipalities do not impose such restrictions because the benefits of collecting far outweigh any possible risks. Most authorities that restrict harvesting have a good reason behind the rules, such as their wish to prevent contamination and ensure the safety of their people. The rules of drinking rainwater are different in every area. Still, the bottom line is that you should install a professional harvesting system to be on the safer side of the law and have a positive health status.
