Answer:
Disadvantages of Rainwater Harvesting. 1. Unpredictable Rainfall: Rainfall is hard to predict and sometimes little or no rainfall can limit the supply of rainwater. It is not advisable to depend on rainwater alone for all your water needs in areas where there is limited rainfall.
Answer:
Disadvantages
1. Unreliable rainfall:
Isn’t it just always the case that right when you need something it suddenly isn’t there? Rain is no different, and it can’t be relied upon to fall exactly when it’s needed. However, here in the UK we shouldn’t worry too much. You are unlikely to spend very long periods of time without plenty of rainwater to use.
2. Starting costs:
Installing a rainwater harvesting system can be costly, with systems ranging from the low hundreds to the low thousands in cost. Similarly to solar panels, costs can be recovered in 10-15 years depending upon the rainfall and the system’s sophistication.
3. High-energy Maintenance:
Rainwater harvesting tanks will take a lot of looking after, and even if this doesn’t cost much in terms of money it can become a chore. Systems can be infiltrated by rodents, algae, and insects, and can become breeding grounds for all sorts of creatures if not properly maintained.
4. Chemical roof seepage:
Some kinds of roof coverings will seep chemicals which will prove harmful to plant life if the water is used to sustain it.
5. Storage limits:
You may find that you cannot store all of the water you would like to, and this could mean having to tailor your water usage to the capacity of the tank.
