Section 69: Superintendent of water or sewer department

Section 69. If a town votes under section twenty-one to have its selectmen act as water and sewer boards, water commissioners or sewer commissioners, the selectmen may appoint a suitable person to act as superintendent of the water or sewer department or designate the superintendent of streets so to act if the town has voted to have its selectmen appoint such officer, who, subject to the control of the selectmen, shall have all necessary powers therefor.

Templeton voted to have independent and separate from the selectmen, elected sewer commissioners.

Templeton Sewer department is an enterprise fund operated department.

Templeton Sewer department is not listed in the FY 2019 general fund budget / spending plan.

Sewer users or rate payers, along with other fees (tipping fees)  cover the costs of operating the sewer department, with oversight of the Sewer department is handled by elected Sewer commissioners.

Why else would the selectmen and the Town Administrator speak of indirect costs [such as "charging" the Sewer department if sewer collections were to be handled at town hall in the treasurer/collector office?]
