Okla. Stat. tit. 19, § 19-892: Tolls and charges

For the purpose of defraying the expenses of the organization of

the district and the care, operation, management, repair and

improvement of the property purchased and works constructed,

including salaries of officers and employees, the board may fix

rates of tolls and charges for the use of such system as they may

deem expedient and may change such charges from time to time and the

monies so received shall go into the general funds of the district.

Such tolls or charges shall be payable either monthly or quarterly

as determined by the board of directors and shall become delinquent

thirty (30) days after they are payable and after delinquent shall

be a lien against the separate lots or tracts of land connected with

the sewerage system. The board of directors shall certify any

delinquent tolls or charges to the county treasurer on or before the

1st day of September of each year which shall be collected as other

delinquent taxes are collected.
