Simple Wastewater Treatment for Off-grid Water System

When I got back from being away for the winter I found that my water pump was no longer able to pump water out of my cistern. In my house, I drink and use rainwater caught off my gutters and stored in an 1100 gallon cistern underground. In this video, I try to figure out why I'm not getting any water. Was it the -18°F temps over the winter or something else that caused the problem?
