Iowa Board of Health on Pressure Tanks
In Iowa the State Board of Health, according to advices from Des Moines, now requires that all new water works in cities and towns in the state shall meet with the board’s approval and the board’s engineer has refused to sanction construction of systems where the pressure tank is intended as a substitute for the high reservoir or tank and it is stated that there is not going to be any approval of systems which depend on buried air pressure tanks for all the force needed for fire protection. Their standard system for small cities and towns is an elevated tank with some pumping system. Recently some of the small towns in the state have installed a pressure tank system, sometimes one tank and sometimes two, with a pump worked automatically by electric power to maintain the pressure. Underwriters declared this a weak proposition in case of fire; that the wires may be broken at a critical moment. Some time ago a tentative plan for an elevated tank was approved for Alexandra, Franklin County, but now word has been received that a pressure tank has been contracted for and reports from Des Moines are to the effect that if this is found to be so the State Board of Health will take up the matter. It is also stated that similar systems have been installed at Gilbert Station, Ellsworth and some other places.
