(2) 
Connection to other water sources.
(a) 
Consumers connected to the County water supply system shall not connect water supplies from other sources (such as, but not limited to, wells) to their house water supply system. The offer to use or the use of protective devices of whatever kind is not a basis for an exception from the provision of this rule.
(b) 
Private wells shall not be allowed when the property is connected to the water system. Immediately upon the connection to the County water distribution system, property owners shall be required to properly abandon all private wells on the property.

I. 
Changes in load. Any increase in size of meter required after the initial installation will be at the owner's expense, in accordance with the County prevailing prices. In cases where a meter is substantially oversized, the County may require the property owner to install a smaller meter at the owner's expense.
J. 
Condominiums would require separate meters and water/sewer service lines for individual tenant spaces, unless a condominium association is legally established to the satisfaction of the County Engineer for the purpose of being responsible for the single building meter, water/sewer service line, and water/sewer charges.
A. 
Calibration. Should any customer of the County doubt the correctness of the water meter readings, the customer may have said meter tested, upon written application to the Department of Fiscal and Administrative Services and by making a deposit, as indicated by the latest Fees and Charges Schedule, to defray the cost of said meter test. Should such accuracy test show the meter in question to register a flow of less than 104% of the actual flow, the customer shall bear the cost of said test. On the other hand, should the test show said meter to be registering a flow of more than 104% of the actual flow, the required deposit shall be refunded, and the entire cost of the test in this latter event shall be borne by the County.
B. 
On-site leak. Should any water customer of the County suspect a plumbing leak on the customer side of the water meter, a request in writing can be made to have a leak test performed at the premises being served.

Customer account fees. A flat fee per bill will be collected to offset the costs associated with maintaining the account. The fee amount is specified in accordance with the latest Fees and Charges Schedule.
F. 
A bill for water service is mailed directly to the property owner who is primarily responsible for payment, or, if the property is leased, to the agent or tenants a proper renter's and/or property management from the billing office is completed and signed by the owner or property manager.
G. 
A onetime fee will be included with a customer's first bill after each new customer account set up. This includes new tenants, vacancies, owners moving back into previous rentals and new owners. The fee, in accordance with the latest fees and charges, offsets the costs associated with transferring customers on the accounts.
A. 
Bills for water charges are payable from the date of posting/mailing up to the billing due date indicated on the bills. A bill for which payment is not posted on the account by the due date becomes delinquent and shall be charged a penalty as established by the County.

Service will not be restored for new owners without balances paid. Payment must be made and posted on the account before 3:00 p.m., subject to change as determined by the Department of Fiscal and Administrative Services, on Monday through Friday, in order for the water service to be restored that same day. If the payment is made after 3:00 p.m., time is subject to change, the water service will be restored during the following business day.
(2) 
Due to the unknown structural integrity and age of the premises' pipes, there is an increased risk of pipes bursting once water service is resumed after having been shut off for two days or more. Services terminated longer than two days shall require an appointment to be scheduled for service restoration, and shall require that a property owner be on-site during restoration of service to verify there are no breakages, leaks, open valves, etc., which may cause damage or high service bills.

H. 
Leaks or waste. All water passing through a meter shall be charged for at the regular rate, and no allowance will be made for excessive consumption due to leaks or waste.
I. 
Turning off water. The County reserves the right, at all times, after due notice, to shut off water for nonpayment of bills, meter nonservice, or for neglect or refusal to comply with the Water and Sewer Ordinance of Charles County. There will be a charge for the resumption of said service, as specified in § 291-19A above.

A fee determined by the department will be applied to the account for any appointment missed. Any property damage resulting from restoration of service shall be the responsibility of the property owner, whereas the County shall not be liable, as it is the property owner's responsibility to be on-site during restoration of the service to verify there are no breakages, leaks, open valves, etc., which may cause damage or high service bills.
N. 
Pressure-reducing valve required where the pressure at any fixture on a premises is found, known, or planned to exceed 80 psi, the owner or their agent shall be required to make such corrections as may be necessary to limit the water supply pressure at any fixture, appliance, appurtenance, or outlet to not more than 80 psi under no-flow conditions.
