All persons owning property upon streets where paving is to be laid
shall lay connecting pipes from the sewer, gas and water mains to the curbline,
under the direction of the City Engineer, where not already provided, at their
own expense. If such connections are not made within 20 days after service
of notice, the same shall be done by the City and the cost collected, with
a penalty of 10%, from the owner as a municipal lien against real estate.
However, this shall not apply to those persons who already have effective
water and gas connections or who now have, or are about to have, sewerage
to other adjoining streets or alleys than the one to be paved.
It shall be unlawful for any person to open or use any drain in such
a way that the same is discharged upon any public street, alley or highway
of the City, except in unsewered districts.
