be cleaned as often as, in the opinion of the Health Commissioner,
they become a nuisance and dangerous to public health.
All applications for the cleaning of vaults and cesspools shall

agent. A deposit of $100 shall be made on orders for cleaning cesspools
and cleaning vaults, against the cost of performing such work for

will be charged for and a bill rendered, and a rebate will be made
if the cost is less than the amount deposited.
