P-803.1 Neutralizing device required for corrosive wastes. Corrosive liquids, spent acids or other harmful chemicals that destroy or injure a drain, sewer, soil or waste pipe, or create noxious or toxic fumes or interfere with sewage treatment processes shall not be discharged into the plumbing system without being thoroughly diluted, neutralized or treated by passing through an approved dilution or neutralizing device. Such devices shall be automatically provided with a sufficient supply of diluting water or neutralizing medium so as to make the contents noninjurious before discharge into the drainage system. The nature of the corrosive or harmful waste and the method of its treatment or dilution shall be approved prior to installation. All discharges into the public sewers are subject to regulation by the Philadelphia Water Department. The Philadelphia Water Department prohibits the discharge of any corrosive liquids, including but not limited to spent acids or other harmful chemicals that destroy or injure a drain, sewer, soil or waste pipe, or create noxious or toxic fumes or interfere with sewage treatment processes. Where treatment prior to discharge is required, liquids shall not be discharged into the plumbing system without being thoroughly neutralized or treated in compliance with Philadelphia Water Department regulations.
