These Regulations may be cited as the Water Pollution Control (Effluent and Waste Water) Regulations, 1993.

In these Regulations unless the context otherwise requires-

"aquatic environment" means all surface and groundwaters, but does not include water in installations and facilities for industrial effluent, sewage collection and treatment;

"discharge" means spilling, leaking, pumping, pouring, emitting, emptying or dumping;

"effluent" means waste water or other fluid of domestic, agricultural, trade or industrial origin, treated or untreated and discharged directly or indirectly into the aquatic environment;

"inspectorate" means the Environmental Inspectorate established under section eighty-one of the Act;

"inspector" means a person appointed as such under section eighty-three;

"licence" means a licence to discharge effluent issued under section thirty-one;

"pollutant" means any substance or energy which if it enters or is discharged into water may cause discomfort to, or endanger the health, safety and welfare of persons, or may cause injury or damage to plant or animal life or property, or which may interfere unreasonably with the normal enjoyment of life or

property or use of property or conduct of business and those objects or substances as may inadvertently obstruct or divert the natural flow of a water course when discharged or dumped into it;

"sewage" means waste water generated by residential and commercial establishments;

"sewage system" includes sewage treatment plants;

"waste water" means water which has been used for             domestic, commercial, agricultural, trading or industrial purposes and as a result of such uses may cause water pollution when discharged into the aquatic environment;

"water pollution" means the introduction, directly or indirectly of pollutants into an aquatic environment.

(1)   A local authority intending to operate a sewage system or owner or operator of any industry licence or trade which will discharge effluent into the aquatic environment shall apply to the Inspectorate for a licence in Form WPI set out in the First Schedule and  shall pay the appropriate fee set out in the Second Schedule.

(2)    A local authority operating a sewage system or owner or operator of any industry or trade discharging effluent into the aquatic environment before the commencement of these Regulations shall apply to the Inspectorate for a licence, referred to in sub regulation (1) within thirty days from the commencement of these Regulations.

(3)    The application referred to in sub regulation (1) shall contain information relating to the quality and quantity of effluent, its treatment and such other information as the Inspectorate may require.

(1)    A person intending to withdraw water from a water course or any other source for the purpose of diluting an effluent shall apply to the Inspectorate water for a licence in Form WP2 set out in the First Schedule and shall pay the appropriate fee set out in the Second effluent Schedule.

(2)    A person who has been withdrawing water from a water course or from any other source for the purpose of diluting effluent before the commencement of these Regulations shall apply for a licence referred to in sub-regulation (1) to the Inspectorate within thirty days of the commencement of these Regulations.

(3)    The application referred to in sub regulation (1) shall contain information relating to the amounts of water required, the treatment of effluent and such other information as the Inspector may require.

5.

6.

(1)   The Inspectorate shall issue a licence to  discharge effluent in Form WP3

        of the First Schedule if -

(a)   satisfied that the applicant has adequate and appropriate facilities

       and equipment for pre-treatment and the effluent will not cause

       significant damage to the environment;

(b)   the Inspectorate had published its intention to issue the licence by

        notice in the Gazette, twenty-eight days before the issue of the

        licence.

(2)   The licence to discharge effluent into the aquatic environment shall -

(a)   conform to the conditions and standards for chemical and physical

       parameters contained in the table of standards for effluent and

       waste water, set out in the Third Schedule;

(b)   be subject to such other conditions as the Inspectorate may

       determine; and

(c)   be valid for thirty-six months and may be renewed for a like period:

       Provided that the Inspectorate may limit the validity of the licence

       for any period less than thirty-six but not less then six months

       when necessary.

(1)   The Inspectorate shall issue a licence to withdraw water from a water course or other source for the purpose of diluting effluent in Form WP4 of the

First Schedule if -

(a)   satisfied that the water being withdrawn            from the water course or

       source would not significantly affect the life of the water course or

       source;

(b)   satisfied that the applicant will treat the effluent in a manner that

        would have no adverse effect on the aquatic environment;

(c)   the Inspectorate had published the intention to issue the licence by

       notice in the Gazette, twenty-eighty days before the issue of the

       licence

(2)   The licence to withdraw water from a water course or source for the

        treatment of effluent shall -

(a)   be subject to such conditions as the Inspectorate may determine;

       and

(b)  be valid for thirty six months and may be renewed for a like period:

      Provided that the Inspectorate may limit the validity of the licence

      for any period less than thirty-six months but not less than six

      months, when necessary.

(1)   The holder of a licence under these records Regulations shall -

(a)   keep a record of the licensed activities;

(b)   submit the record referred  to in paragraph (a) to the Inspectorate

        every six months from the commencement of the licensed

        activities;

(c)   report to the Inspectorate abnormal discharge of effluent.

(2)   The Inspectorate may order the holder of a licence under these Regulations to install at the expense of the holder of the licence, metering devices and to take samples and analyze them as the Inspectorate may direct.

An Inspector may at any reasonable time enter any premises on which a licensed activity is being conducted and take samples analyze and examine materials used for the licensed activity.

The Inspectorate shall maintain a register of holders of licences to discharge effluent into the aquatic environment or to withdraw water from a water course or any other source for the purpose of diluting an effluent to make it acceptable.

Any person who -

(a)   operates or owns a sewage system or an industry or trade which

       discharges effluent into the aquatic environment without a licence;

       or

(b)   withdraws water from a water course for the purpose of diluting

        effluent without a licence;

                    shall be guilty of an offence.

(1)   If the Inspectorate has reasonable cause to believe that a person is contravening any of the provisions of these Regulations or any condition of a licence or is likely to contravene any of the provisions of these Regulations or a condition of licence, the Inspectorate shall serve an enforcement notice on that person;

(2)   An enforcement notice shall -

(a)   state the belief regarding the contravention of the Regulations or a

       condition of the licence and specify the matter constituting the
