# Why will a lone pair from H2O not attack a C+ atom in elimination reaction?

In step three of reaction between H2SO4 and alcohol, why will the H2O attack the H atom instead of the C+ atom? they both have positive charge and in nucleophilic substitution reactions the c+ atom is attacked. (Image taken from chem guide )

If $$\ce{H2O}$$ attacks the $$\ce{C+}$$ atom, it will produce the original alcohol back. No chemical effect.
