You could put screens in the ground around the basements. Problem might be the sand not being pourous enough to pass water quickly enough to make a difference.
Putting in multiple points and tying them together makes for a lot of fittings which is bad in any suction line. There will always be suction leaks, no matter how small and they will cause problems.
If it were mine, I would try to sink a bunch of points, tie them together and run them into a catch basin underground at an elevation that the points can run into it with gravity alone. Then pump with a submersible Sump or Sewage Pump to a drainage area.
