CHAPTER 33

SEWER AND SEWAGE CODE

SANITATION AND MAINTENANCE SERVICE

SECTION A.

Sewer Permit Required. No person shall make any connection with any public sewer, either directly or indirectly, without first having obtained the proper permit and paid the required fee.

Application for Permit. An application for a permit to connect to any sewer, inside the corporate limits of the Reservation, must be made in writing by the owner, who must state the location of the property to be served, the lot and block numbers, also for what purposes the premises to be served will be used. After application has been approved by the Sanitation Maintenance Service, a permit will be .issued upon payment for each connection to be made either directly or indirectly with the Sanitation Maintenance Service Sewer System.

No person except a Master Plumber or a Pipe layer shall be permitted to make the connection or do any work in the streets or alleys.

If it is found necessary to tap a sewer at any other place that where a "Y" has been placed, the Sanitation and Maintenance Manager must be notified and the break into or tap must be made under the supervision of the authorized Sanitation Maintenance Service Representative. No sewer work shall be covered until it has been inspected and approved by the authorized Sanitation Maintenance Service Representative.

Returns. All Master Plumbers and Pipe layers shall, within forty-eight (48) hours after making a connection with a sewer, make a return to the Sanitation Maintenance Service Office, certifying thereon that the connection covered by the permit was made according to Sanitation Maintenance Service ordinances, and show the exact location (as-built drawing) of the connection, also the size, length and location of the service. The Sanitation Maintenance Service may refuse to approve any more connection permits for any person who has failed to make a return within forty-eight (48) hours for any previous water tap or sewer connection.

Sewer Connections at Owner's Expense. All sewer connections from the public sewer to the user's property shall be laid and constructed by a Master Plumber or Pipe layer, and the Sanitation and Maintenance Service shall not be responsible for any expense in connection therewith.

Owner's Duty To Maintain Private Sewer Lines and House Connections . If any person shall fail to properly maintain a private sewer line or any house service sewer line, the supply of water may be shut off from the premises served as provided for in the Water Code.

Sewer Tampering. No person shall open any manhole or catch basin along any sewer without prior authorization from the Sanitation Maintenance Service.

Receiving Stream - shall mean that body of water, stream or water course receiving the waters discharged from the sewage treatment pond or the watercourse formed by the effluent from the sewage treatment pond.

Sanitary Sewer - shall mean a sewer that carried sewage or industrial wastes and to which storm, surface or ground waters or unpolluted wastes are not intentionally admitted.

Sewage - shall mean the water-carried human, animal and household waste in a community or private drain. Such term may include ground water infiltration, surface draining and industrial wastes .

Sewage Treatment Works - shall meaty the arrangement of devices and structures for treating sewage, industrial waste and sludge.

Sewage Works - shall mean all facilities for collecting, pumping, treating, and disposing of sewage; namely the sewage system and the sewage treatment works.

Sewer - shall mean a pipe or conduit for carrying sewage or other waste liquids.

Sewage System - shall mean the network of sewers and appurtenances for the collection, transportation, and pumping of sewage and industrial wastes.

Sludge - shall mean any discharge of water, sewage or waste exceeding a concentration or flow greater than five times that of the average twenty-four hour discharge from the person, which is discharged continuously for a period longer than fifteen minutes.

Suspended Solids - shall mean solids that either float on the surface of, or are in suspension in water, sewage, or other liquids and which are removable by laboratory filtration.

Unpolluted - such terms shall mean unaffected by sewage or industrial wastes.

Pretreatment of Industrial Wastes - where required, in the opinion of the Sanitation Maintenance Service, the owner shall provide, at his own expense such preliminary treatment or handling as may be necessary to:

(a) Reduce BOD to 300 ppm, IDOD to 100 ppm and suspended solids to 350 ppm.

(b) Modify the objectionable characteristics or constituents to come within the maximum limits provided for in the preceding paragraph.

(c) Control the quantities and rates of discharge of such waters or wastes over a twenty-four hour day and a seven day week.

Plans, specifications and any other pertinent information relating to proposed preliminary treatment or handling facilities shall be submitted for the approval of the Sanitation Maintenance Service. No construction of such facilities shall be commenced until approval is obtained.

Discharge of Wastes - Generally. Except as provided in this Chapter, no person shall discharge or cause to be discharged any of the following described wastes or waters into any public sewer.
