Using 555 timer I can control the water pump...when water reaches to minimum level (push to break) pump starts and when water level reach to maximum level (push to make) pump will turn off

Not a bad design, a couple of things to consider though, 1. A 6v motor on a 5v power supply will probably have trouble starting under load. 2. The reason the switch has to be held in is that the system time clock is set to a low time, it needs to be about 400 ms/s, this setting will also allows the motor to be seen to rotate. 3. The motor can get up to speed faster if the EM Time constant is wound back a fair bit. 4. Both transistor base resistors could be a lot larger. 5. The circuit function is a lot easier to understand if it is tidied up a bit. http://everycircuit.com/circuit/4765401873645568
