One more way we help you innovate.
In Nigeria the norm for water is to pump water from your well into a holding tank and gravity feed it into your house. The more complicated systems use multiple pumps /tanks and a pressure pump to get water into the house.
This creates it’s unique challenge and solution. The water inside your well is as clean as can be. You expend energy to remove it from the ground and store it in a tank and then use a pressure pump to send it into the house. The energy used can be as much as 3 kw. Each pump is between 1 and 1.5 hp. The other problem that you encounter is algae that grows inside your storage tanks. I am sure you remember washing your tanks every 3 to 6 months and the dirt that comes out of it plus the hassle and pain involved.
The reasons people use gravity to create pressure is because of the poor power situation in Nigeria. This is no longer a valid excuse.
