A separate, smaller reservoir with its own conditions and a lot of older equipment.
Installations here trend smaller and older than on Lake Norman proper. Lighter loads mean drives last, and the practical constraint moves from wear to parts: older lifts are more likely to need a component that is no longer made.
Where a part is genuinely obsolete, the honest conversation is about adapting or upgrading a subsystem rather than pretending a like-for-like replacement exists.
Obsolete components on older lifts, where like-for-like replacement may not exist.
