Sec. 118-191. Special structures and details.

(a) Manholes. Manholes shall be required at the junction of two or more six-inch or larger lines. In consideration of building sewer length and waste characteristics, a manhole may be required on the upper end of a building sewer greater than four inches in size. Connection of a five-inch or larger building sewer to a city sewer shall be accomplished by means of a manhole. Manholes shall be constructed at spacings not to exceed 300 feet and at changes in alignment or grade on building sewers six inches and larger.

(b) Sand traps. Connection of vehicle washing facilities or other grit producing discharges to the city sewer shall be preceded by a sand trap. The sand trap or any open grating must be located so as to completely exclude the possibility of rainwater entering the sewer. No connections may be approved to the city sewer which will allow the entrance of rainwater into the sewer.

(c) Grease interceptors. Grease interceptors or traps shall be required for the proper handling of liquid wastes containing grease in excessive amounts, except that such interceptors shall not be required for private living quarters or dwelling units. All grease interceptors shall be routinely maintained to prevent the discharge of grease in excess of 100 mg/liter to the city system.

(d) Control manhole for observing, sampling, measuring industrial wastes. When required by the director, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole together with such necessary appurtenances in the building sewer to facilitate observation, sampling and measurement of the wastes. Such manhole, when required, shall be accessibly and safely located, and shall be constructed in accordance with plans approved by the director. The manhole shall be installed by the owner at his expense and shall be maintained by him so as to be safe and accessible at all times.
