Any tanks or equipment used for hauling septage from private sewage disposal systems shall not be used for hauling hazardous or toxic wastes as defined in 567-Chapter 131 or other wastes detrimental to land application or wastewater treatment plants and shall not be used in a manner that would contaminate a potable water supply or endanger the food chain or public health.

b. Pumps and associated piping shall be installed with watertight connections to prevent leakage.

c. Agitation capability for use in cleaning private sewage disposal systems to disperse sludge and scum into the liquid for proper cleaning shall be provided.
