Any person, owner or reputed owner having any interest in any property against which the board seeks to make a service and benefit charge under this chapter, may object thereto. All such objections must be in writing and filed with the board before the hearing is commenced upon the roll containing such properties and must state clearly the grounds of such objection. Objections not made within this time and in this manner shall be deemed conclusively to have been waived.
