Can a submersible pump and manual pitcher pump coexist?

Such deep well "force" pumps have actually existed for probably 100 years or
more. They have been operated by hand levers or mechanical "pump jacks"
worked by motors or windmills.
Or steam engines. I think the original Cornish beam engines operated
pumps deep in the coal mines in basically this way.
