While in the progress of construction of any sewer or stormwater drain in the City, the contractor engaged in such construction may erect standpipes, at suitable locations, upon the request of any owner of property abutting on the particular section indicated in the request for such standpipe.
No such standpipe shall be erected at the expense of the City, but it shall be at the expense of the property owner requesting such installation.
Such standpipe shall be brought to such height as is proper for the drainage of the property and is suitable to the owner of the property.
Such standpipe must be erected before backfilling takes place.
Such standpipe must be erected under the supervision of the Director of the Bureau of Plumbing who is then inspecting sewer connections during the progress of the work.
Before entering into any agreement with a property owner for the erection of a standpipe and before beginning construction thereof, the contractor shall file a written stipulation with the Commissioner of the Department of Public Works to the effect that:
The performance of such work would not hinder, delay or be advanced at any time by the contractor as reason for delay in the construction for the sewer.
The standpipe would not in any way contribute to the inadequate functioning of the sewer.
No direction given by the Director of the Bureau of Plumbing regarding such standpipe shall be offered at any time by the contractor as a reason for delay in the construction of the sewer.
By undertaking such private work under City inspection, it would in any manner operate as a modification of the contract under which the contractor is constructing the sewer or stormwater drain for the City.
