Wastewater flow measuring devices shall be maintained in good working order.
In cases where water meters are used as a basis for billing wastewater service, the terms and conditions for testing meters and billing adjustments shall be as provided in PSC Order No. 2076, relating to service governing water utilities.

System expansion, even within the certificated area, shall not commence without approval of the plans by the Department of Natural Resources and Environmental Control (DNREC Reg. 4.06).
3.1.1 If the construction of an extension involves the acquisition of a private right-of-way, then the prospective customer or developer shall attempt to secure the right-of-way and deliver it to the utility free of cost before construction of the extension is started. If, however, it is not reasonably possible for the prospective customer or developer to secure the right-of-way, and the construction of the extension involves the utility’s incurring expenses for right-of-way easements, such costs shall be added to the total cost of the extension.
3.1.2 Utilities are required to incorporate the terms and conditions applicable to contributions in-aid-of construction and refundable advances in their tariff rules and regulations.
3.2 Wastewater Plant Operation. The utility's wastewater plant shall be constructed, installed, maintained, and operated in accordance with current engineering practices in the wastewater industry, to assure, as far as reasonably possible, continuity of service, uniformity in the quality of service furnished, and the safety of persons and property, in compliance with relevant DNREC and Health Department regulations and policies.
3.3 Wastewater Plant Inspection. Each utility must adopt and file with the Commission a program of inspection of its wastewater plant in order to develop a capital improvement plan. The frequency of the various inspections shall be based on the utility's experience and accepted good practice. Each utility shall keep sufficient records to give evidence of compliance with its inspection program.
4.0 Operation
4.1 System Safety Program. Each utility shall exercise reasonable care to reduce the hazards to which its employees, customers, and the general public may be subjected. A safety program should be adopted by each utility, fitted to the size and type of its operations.

5.1 Application For Service.
5.1.1 Rate Schedules. If applicable, each utility shall assist the customer or applicant in selecting the most economical rate schedule. If, after the selection of a service line diameter, the customer determines that a different size service is needed, the full cost of the new service or other facilities requested by the customer will be the responsibility of the customer.
5.1.2 Customer Notification. Customers affected by a change in rates or service schedule classification shall be notified by the utility.
5.1.3 Tariff Notice. Each utility shall keep in each office of the utility where applications are received, a copy of its currently approved tariff available for public inspection at any reasonable time.
5.1.4 Meter Reading. Every customer served by a wastewater utility shall be informed of the method of meter reading if meters are in place for billing purposes.
5.1.5 Interest on Deposits. When a utility's tariff requires or permits the collection of a deposit from customers, the utility shall pay interest on all such deposits at the rate of six percent (6%) annual simple interest. Interest shall be computed from the date of receipt of the deposit by the utility.
5.1.5.1 Interest on deposits shall be credited to the account of the depositor annually, at the time the deposit is returned, or when service is terminated, whichever is sooner; and
5.1.5.2 Deposits shall cease to draw interest on the date service is terminated, on the date the deposit is returned, or on the date that notice is sent to the depositor's last known address that the deposit is no longer required.
5.2 Billing Statement Adjustment. If wastewater service is billed on the basis of metered water usage, billing adjustments shall be calculated on the premise that the meter should be 100% accurate. For the purpose of a billing adjustment, the error in registration of the meter shall be calculated and applied as specified in the meter test rules of the wastewater utility tariff or PSC Order No. 2076 governing minimum service standards provided by public water companies.
6.0 Front-end Capital Contributions
Front-end capital contributions shall be required from all new connections to recover, at least in part, the cost of constructing conveyance, treatment, and disposal facilities incurred by the utility where applicable.
