sewer overflow is the responsibility of the property owner, and will refer the name
and address of the property owner to CDPHE for action.
Private sewers and pump stations are intended to serve only site specific
developments, (i.e., shopping centers, business parks, campuses, golf courses,
special area plans, condominium developments, subdivisions where the
subdivision approval process includes special permission from the City Council
for the sanitary sewer system within the subdivision to remain private, etc.) and

property not abutting on the line of such sewer, the City Council shall cause such
cost to be zoned in such manner as to include all benefited property according to
the benefits derived. The cost to be charged to the City, if any, shall be
determined by the City Council according to the extent and use of such extension
