This old ferro cement tank was built back in spring of 1980. The primary builders were my brothers Matt and Tom. They had never actually built one by themselves before, however, they had helped a neighbor to build one a few months earlier. My brothers were not afraid of failure. They needed water storage, and this was in an era before the easily had plastic tanks were on the market, so they just launched this project. All in all, considering this was the first one of four to be built in our neck of the woods, it has done remarkably well. The biggest mistake, was deciding to build the cement lid right onto the tank. For many practical reasons, this was a natural decision, and one for which no one could predict the natural consequences. Because of the intense exposure to the sun, the cement would absorb the heat of the rays, and unfortunately begin to expand. Since the lid was solidly connected to the sides by multiple rods of 1/2 inch steel, as the roof expanded so did the walls causing cracking and water leakage across the entire tank. In the evolution of tank building, it was found that building the tanks with a redwood roof that was added after the fact proved to be a far superior design. This past summer, the original contractor, Matt, had a chance to redefine this tank in a new and modern manner. With great time and effort, the cement roof was cut away, and the walls were allowed to free stand. Foundation wire was wrapped around the entire tank, and then galvanized 1/2 inch wire was fastened to the foundation wire to make a very strong barricade. My brother Mark assumed the time consuming task of wiring the galvanized 1/2 inch wire to the foundation wire, and this took many hours of listening to Van Morrison with a pliers in hand. But accomplished it was, and then the real party began. A crew of six showed up one Saturday morning, and the tank was re plastered with two coats. This took the bulk of the day, and lots of sweat. After the cure, Matt applied a coat of Thoroseal to the outside, and then the water began flowing. As you can see from the picture, it holds over 9,000 gallons of water rather successfully. Maybe a roof will follow down the road. But for now, we all are happy that our efforts were successful.
