For the purpose of this title certain words and terms are defined as follows:
"Domestic sewage"
means water which has been used for washing and flushing waste products from the home;
"Equivalent of domestic sewage"
means wastes not constituting a greater load of oxidizable organic material and settleable solids or otherwise constituting a greater loading or burden upon treatment plants, or otherwise requiring greater, more or different treatment, care and attention than domestic sewage;
"Industrial wastes"

(Prior code § 26-1)
The sewage disposal system of the city and the county sanitation district No. 2 were constructed and are operated and maintained primarily for the disposal of domestic sewage.
The disposition of industrial wastes shall be permitted through the sewage systems only to the extent that the same may be done without interfering with the ability of said systems to dispose of domestic sewage. Industrial wastes shall not be permitted in said systems to an extent or of such a character as to cause overloading of the. carrying capacity or of the treatment capacity of said systems, or of such character or quantities as to cause damage to the facilities thereof. Said sewage disposal systems must be operated in such a manner as not to constitute a nuisance or to cause odorous or other objectionable conditions along transmission lines or in the vicinity of treatment plants and other facilities of said systems.
(Prior code § 26-2)
Before any person discharges industrial wastes into the municipal sewers of the city, it shall be the duty of such person to first apply to, and obtain from, the city engineer a permit therefor.
(Prior code § 26-3)
Application for permit to discharge industrial wastes in the municipal sewer shall be made in writing to the city engineer and shall contain the following information:
(1) 
Name and address of applicant;
(2)

(1) 
That there is unused carrying and treatment capacity not necessary for the disposition of domestic sewage of the city;
(2) 
That the amount and character of the wastes proposed to be discharged by applicant is such that the same can be transported and treated in such a manner that an effluent will result which complies with all applicable state laws and regulations, and which, in the opinion of the city engineer, will not result in a nuisance nor any objectionable or unpleasant odors along the pipe fines or in the vicinity of treatment plants and other facilities;
(3) 
That such wastes will not result in damage to pipe lines and other disposal facilities, he shall issue to applicant a permit, as requested.
(Prior code § 26-5)
The city engineer, in his discretion, and toward the end of fulfilling the intent and purpose of this chapter may grant an application in part only, and may prescribe conditions with respect to discharge of such wastes into such sewers, and may require treatment thereof by applicants before granting a permit.
(Prior code § 26-6)
In the event of demands upon the sewer systems by several applicants which in the aggregate exceed the surplus capacity of such systems, the city engineer shall prorate among the several applicants the available carrying and treatment capacity upon an equitable basis, taking into consideration the total amount of industrial wastes of each applicant and the character and quantity of such wastes.
(Prior code § 26-7)
In the event that after the granting of a permit, as provided for in this title, it shall develop by reason of increased flow of domestic sewage, or for any cause whatever, that the discharging of such wastes in pursuance of such permit, causes the carrying or treatment capacity of said systems to be exceeded, or causes a nuisance or objectionable or unpleasant odors or conditions along the lines or in the vicinity of treatment plants or other facilities, or resulting in damage to pipelines or other facilities then, in his discretion, the city engineer may revoke the permit, or may impose further conditions with respect thereto, toward the end of remedying such conditions.
