Run  some 220V wiring in pvc underground (licensed electrician) to power a good pump if you have space/amperage reserve in your electrical panel. 220V requires less current to run than a 120V for the same power, so it's more efficient.This guy has a lot of good videos on diy yard drainage systems.

Also, I would be very concerned with thinking you can DIY your first renovation.

Hello,I have a property with a tenant that I inherited when I purchased the property..She is an older woman with adult children that, at one point, moved in with her without notifying me.We've got that all cleaned up, but now she is adopting a 2yo child.It's a noble act, but how does this effect me as the owner?

It looks really solid and the roof sheathing and everything else looks very clean and dry.

It looks like the pump is connected to an ABS (plastic) drain pipe going into the ground and that like should not be clogging, at all, if the pump is working properly.Every plumbing system with a pump needs a high number of clean-outs to access the pipe so you can clean the pipes with the proper equipment.
