what do u mean exactly I don't understand
Answer:
Water tanks aren’t always built at an elevated height, in fact for the majority of those within Australia utilising a water tank for household purposes, the water tank is actually located beneath the level of the water harvesting source.
This kind of setup will need a pump to supply the water to the home, however interestingly there are two types of systems when it comes to pipework.
Dry Water Harvesting System
It’s called a dry system as water is not contained within the pipework apart from when water is being harvested. The greatest benefit of dry water harvesting systems is that they are simple. Your pipe runs directly from the gutter to the tank. the limitation to this kind of setup is that the tank needs to be relatively close to the home.

Wet Water Harvesting System
It’s called the wet system as there is always water within the pipework (once the first water has been harvested). The biggest benefit of the we system is that the piping can be concealed more so than a dry system. Things to be aware of are that the system can attract mosquitos so it is important to screen all pipes, and flush them after rainfall.
Another benefit is that the tank does not need to be located directly next to the house. A rule of thumb is that for every 10m away from the water harvesting source, there needs to be 0.5m of fall.
