basement waterproofing question?

I live in a house in a flood zone. On heavy rains my basement use to flood. I had an indoor french drain waterproofing system installed. For 11 years water has been constantly coming into the pit for the sump pump. I burned out 9 pumps. The pump shoots out water every 5 minutes. There is a heavy sewer smell coming from the area of the pump. The sewer line is not broke. How do i get rid of the smell and also how do i stop the water from coming in?
