(a) No person shall discharge or cause to be discharged any storm water, surface water, ground water or roof run-off water to a sanitary sewer. Subsurface drainage may be discharged into a sanitary sewer with the approval of the City Manager or his or her authorized representative, provided that favorable soil and water conditions will prevent excessive drainage.
(b) Storm water and all other unpolluted drainage shall be discharged to sewers specifically designed as storm sewers or to a natural outlet approved by the City Manager and/or the State Water Resources Commission. Industrial cooling water or unpolluted process waters may be discharged, with the approval of the City Manager, to a sanitary sewer.
