I live in Cancan and the system for water storage is an 1100 liter plastic water tank on the top of the second story of the house. The city pressure that supplies water (7pm-10pm daily) no longer provides enough pressure for the water supply to reach the holding tank on the roof. A temporary solution has been to connect a water pump at the street level to pump the supply to the tank on the roof. The roof tank does not provide enough pressure for the 3 bathroom and the washing machine, so I have a pressure pump installed between water tank and the main supply line to the house. When the tank is full all works well, but now that the city water supply has no pressure (4 months now) I am looking for an alternate water storage set up. Can I put a tank in the ground, and if so where then do I need to install the pressure pump. Will I still need a holding tank on the roof and if so, then do I need the pump to get the water to that level. I a perfect world I would like just 1 tank at ground level with whatever connection I need to make for pressure to the house.

If you are going to use a booster pump (like you are presently using), I would put the tank on the ground where the city water could probably fill it, doing away with the need for the first pump. YOu will need to be sure there is a check valve between your tank and the city water supply, which no doubt is already there. If that check valve is there, you can connect your booster pump for the house between the tank and check valve.
