First I had to find a water source that wouldn't freeze in the winter. I have a small creek that runs in Spring and Fall but dries up in the Summer. I have a friend that witches water and loves good micro brew beer. I invited him up to sample my latest batch and suggested he bring his witching sticks. He walked the creek bed and found a strong signal about 3ft from the creek center. I bought a drive point and started hammering it into the magic spot. I hit water at 3ft and kept driving down to 12ft. I then brought in a backhoe and dug down 12 ft and installed some concrete cistern rings. The water even in the middle of Summer stays above half full. I now needed a way to get the water out of the cistern and into something the animals could drink from that wouldn't freeze. I started by building an insulated box around an 80 gallon water tank. I built a small box inside to house a deep cycle lead acid battery. I used cedar shavings for insulation around the tank and hard styrofoam cut to fit in the metal cover I had bent at a local heating and air conditioning contractor.
To get the water from the cistern I purchased a 2.5 amp, 12 volt, Rule brand bilge pump and float switch. I placed the pump well below the surface where it would be covered with water year round. I then plumbed it up and into the 80 gallon tank. The float switch was mounted on a adjustable mount so I could keep it 12" below the surface as the water level changed with the seasons.
I then poured a level slab right next to the cistern, placed the insulated tank, and attached a pole made from electrical conduit to hold my solar panel made with earth4energy plans. The bilge pump runs when the water level trips the float switch pumping about 15 gallons of water from the cistern into the tank. The tank has an overflow at the top that exits the side of the box so the tank doesn't run over. This cycle happens about every 30 minutes in the winter which keeps the water from freezing. Yahoo! With this set up you need to trade batteries about every two weeks due to the shorter days in Winter. You could extend the time by adding another solar panel, or wind generator for more electric input. Be sure to use a charge controller between the solar panel and batteries so they don't over charge. In the Summer I wire the system to a switch that connects when it gets dark so it only runs at night. It then has all day to charge and I never have to switch batteries. This allows me more time to make beer. Yahoo!

How Do You Keep Animals Watered at 20 Degrees Below Zero With No Electricity?
It was so cold that the lawyers had their hands in their own pockets. Flashers were describing themselves. It was also cold enough that the ice on the pond froze to 18" thick. To thick for the cows and horses to break through. I trudged down to the pond morning and night to break the ice so they could drink. This I believe is punishment for some horrible deed I must have committed in a past life. Ta Da, Michael Harvey and earth4energy to the rescue. I needed a solution and I found it in Michael's guide to building your own solar electric systems. Here's my solution.
