two 3000 gallon cisterns ordered from National Tank Outlet in Memphis, Tennessee, were placed on the concrete pad earlier this week. The tanks, at a height of 9 feet tall and a diameter of around 8 feet were no easy task to move and get onto the pad. Students from the MSU's building construction sciences helped place the cisterns in the right spots for future plumbing. Each tank weighed in at about 400 pounds. Made out of polyethylene, the tanks can withstand a great deal of interior force from the weight of the water, as well as exterior forces such as the concrete pad.The final design and construction of cisterns were similar to that of the original design. The first cistern (one closest to the house) still consisted of a 4 inch valve with two 2 inch valves on the bottom 180 degrees from one another and the second cistern had the 1 1/2 inch valve with the two 2 inch valves same as the first cistern. The only difference was the placement of the 4 inch valve. To get maximum tank volume, the inlet was installed on the dome of the tank.
Overall success getting the tanks
in place, thanks very much to
the building construction class that helped. Now that the tanks are placed, plumbing can begin for the actual implementation of the rainwater harvesting system. Piping will be ordered by the end of the week and the installation is planned to take place the first week in December if not earlier. Thanks again to all that have helped with this project.
