If any customer shall move from the premise where service is furnished, or if said premise is destroyed by fire or other casualty, the consumer shall at once inform the Director of Public Works who shall cause the sewer service to be shut off from said premise. If the customer should fail to give notice, the customer shall be charged for that period of time until the official in charge of sewers is otherwise advised of such circumstances.
It shall be unlawful for any person to discharge or cause to be discharged any stormwater, surface water, groundwater, roof runoff, surface drainage or unpolluted industrial process waters into the sanitary sewer.

A. 
In the event of a customer of the Municipal Sewer Department discharges an unusually large amount of waste daily, an unusually large amount of grease or oil or waste with an unusually high biochemical oxygen demand, the Director of Public Works may require said customer to install interceptors or other preliminary treatment equipment to reduce the objectionable characteristics of the waste to within such maximum limits as he shall prescribe subject to the review of the Council. All preliminary treatment facilities shall be purchased and maintained continuously in satisfactory and efficient operation at the customer's expense.
B. 
Nothing herein shall be construed to prohibit a special agreement or arrangement between the Council and an industrial concern whereby an industrial waste of unusual strength or character may be accepted by the municipality for treatment subject to additional rental fees or other charges.
Entrance into a manhole or opening for any purpose except by authorized persons is hereby prohibited. It shall be unlawful to deposit or cause to be deposited in any receptacle connected with the sewer system any substance which is not the usual and natural waste carried by the sewer system.
The Director of Public Works or his authorized agents shall have free access between the hours of 7:00 a.m. and 6:00 p.m. to all parts of each premise and building which is connected with the sewer system to ascertain whether there is any disrepair or violations of this chapter therein. It shall be the duty of every customer of the Sewer Department to answer all questions concerning the sewer and use thereof.
Any customer feeling aggrieved by reason of any controversy with the Director of Public Works or with the city itself over a sewer billing statement may present his or her grievance to the City Clerk. The City Clerk shall have the authority to adjust or compromise any billing statement in an amount not to exceed the amount set from time to time by City Council per customer per annum. Should the customer still feel aggrieved, after adjustment, compromise or refusal to adjust or compromise by the City Clerk, then the customer shall pay such charge under protest, in which event the City Clerk shall write on the receipt given such customer the words "paid under protest." Such customer may then present his or her verified claim in the manner provided for presenting claims to the City Council for a refund of the amount so paid under protest. Such claim shall then be considered by the Council in the same manner as other claims against the municipality. Any customer who feels aggrieved by being required to pay for the resumption of sewer service after the same shall have been shut off, may protest in the same manner as set forth herein.
[Amended 5-5-1998 by Ord. No. 1264]
Any person who violates any of the prohibitions or provisions of any section of this chapter shall be deemed guilty of a misdemeanor.

A. 
Construction of all new or replacement subsurface wastewater disposal systems must be approved and permitted by the City of Papillion Building Inspector. Building permits for new residences and/or other facilities proposing discharge of wastewater to a subsurface disposal system must include specific data to verify probable successful performance of the system. All applications for permits which propose subsurface wastewater disposal systems will include the following information:
(1) 
Certified report of percolation tests and seasonal groundwater level test hole results. The percolation test results (absorption rate of ground-disposed liquids) must be the basis for the design of all proposed drain field installations, replacements and extensions of laterals. All percolation tests must be conducted by qualified personnel.
(2) 
Site maps, including the location of system components, the building being served and other site improvements such as buildings, driveways, drainage ditches and natural watercourses, public or private water wells in the area, the location of percolation test holes and test boring holes (minimum boring depth shall be 10 feet below natural grade to determine groundwater presence) and cross-sectional drawing of the proposed system and spacing of laterals and the reserve area. Where there are site conditions such as steep or highly variable topography, potential natural waterway obstruction and/or other unusual conditions, additional data must be provided with the site map. These data include such items as the location and elevation of the high seasonal groundwater or other circumstances which create a need for extraordinary design (e.g., full or partial mound systems, dosing systems, stepped distribution systems, drain fields remote from site which are either gravity fed or dose pumped, etc.), spot elevations of the existing ground or contour maps, finished floor elevations of the lowest floor being served by the sewer, septic tank invert and outlet elevations, distribution box elevation, drainfield invert elevations and, as applicable, mound cover elevations, dosing calculations and other data that may be requested. The purpose of these data is to ascertain probable acceptable performance of the proposed wastewater system.
B. 
Site evaluation is the key to drain-field success. Where difficult sites such as those described above are considered, the system must be designed by a registered engineer. All testing, site layout, system design and construction shall be done to Nebraska Department of Environmental Quality Standards: Title 124 - Rules and Regulations for the Design, Operations and Maintenance of Septic Tanks.
C. 
"Qualified personnel" is defined as those who are registered professional engineers or persons who have received special training in conducting percolation tests and are knowledgeable in the design, installation, operation and maintenance of septic tank and subsurface disposal systems and State of Nebraska rules and regulations govern the same. A certificate of attendance at a Nebraska State Department of Environmental Quality organized wastewater treatment workshop or similar equivalent training may be used to meet qualification requirements.
D. 
Proof of qualifications may be provided before or at the time of application of the permit. The city will maintain a register of qualified personnel authorized to perform such work within the city's jurisdiction.
E. 
Except for currently registered professional engineers, all persons seeking listing as a qualified person will provide the City Building Inspector a copy of a certificate of completion of germane, specialized training similar to that cited above. The City Building Inspector will determine the acceptability of all specialized training.
