The diameters of siphon pipes to be cleaned and inspected range from 6-inch to 48-inch and include both single and multi-barrels. Available siphon information, along with maps and as-builts, are found later in these specifications. The Company shall verify the sizes and configurations of each siphon and report any discrepancies to the as-builts to Charlotte Water. Cleaning schedules will vary, as required, and may include the need to perform services during nights, weekends, and/or City observed holidays.
