So we finally got our lake water system set up this season but were only able to use it for a few weeks before we had to shut everything down and evacuate due to an approaching forest fire. The system consists of a 1 HP submersible water pump that directly fills a 32 gallon pressure tank. From there it goes through a 50 micron sediment filter, a 1 micron paper filter and then through a charcoal filter. After that, the water runs up through a 3' long UV sterilizer and into the cabin. The only plumbing fixtures are a shower, bathroom sink and kitchen sink. We still use outhouses and everybody's fine with that. The system worked fine. Water pressure was good and the taste and smell of the water was decent.
When we removed the filters to shut the cabin down for the season and get the hell out of there, the 1 micron filter was completely brown after three weeks of use with 7 people staying in the cabin. I'm sure this is to be expected sucking in lake water but I am just a bit concerned that maybe we need to add a stage or two more, prior to the pressure tank to both do a better job of filtering as well as make the filters last longer. I'm fine with replacing them every season but this filter needed to be replaced now and we were planning to stay another week had we not been evacuated. Just wondering what others do to filter their lake water.
