of clogging. The floor drains need not be more than 2 inches since they carry only water. A grease trap should be provided for waste water flowing from the sink to the main disposal line (this grease trap will have to be cleaned at periodic intervals of 30 to 45 days). WATER SUPPLY To further conserve on costs, the oneinch water supply pipe (copper or galvanized) that comes off the main line could be left outside of the partition that faces the inside wall of the storage room and run underneath the back counter of the refreshment stand. The only portion of water pipe not recommended for exposed installation would be that supplying the drinking water. In frame construction, this should run through the studs (by boring a lJ/2-inch hole) and the partition, with an elbow protruding for hooking up later. This will avoid the possibility of having someone pull the pipe off the wall after you are in actual operation. As indicated on the plan, to get water to the outer counters for refreshment operation and cleaning, the one-inch pipe line will have to be dropped below the finished concrete floor grade and come up out of the floor at its desired location. The same applies to the floor drains, the top of which must be provided for in the roughing-in of the plumbing, so as to make the top come even with the finished poured concrete flooring. TEMPORARY SUPPORT If you are concerned about supporting your inside partitions and the weight of the roof, until plumbing and electrical lines are in, it is well to build up beneath the studs with concrete blocks, wedging them tightly at distances of every 3 or 4 feet with small pieces of lathe or wood blocks. These can be removed when your floor is poured. The same applies to the placement of your tank. This can be set up on concrete blocks wedged in on each side to keep it from moving in any direction. You are then in a position to tie in your well with your storage tank to provide water for the workmen on the premises with a small gasoline motor pump to get enough supply. Another procedure is to arrange for the position of the 2-inch main that will come out of the tank to hang from the ceiling, but not to place your tank, using a hand pump set up on top of the casing. In any event have jour local board of health check the water before the workmen drink it.
