All costs and expenses incidental to the installation, connection and maintenance of a building sewer shall be borne by the lot owner. The lot owner shall take all risk of damage that may result from water settling back on his or her premises from the main sewer. Drainage piping serving fixtures which have flood level rims located below the elevation of the next upstream manhole cover of the public sewer serving such drainage piping shall be protected from backflow of sewage by installing an approved-type backwater valve. Fixtures above such elevation shall not discharge through the backwater valve. The owner is required, at his or her expense, to install the backwater valve and to keep the same in repair. The owner shall indemnify the City from any loss or damage that may directly or indirectly be occasioned by the installation of the building sewer.
