Best Management Practice

(BMP)• Best Management Practices (BMP) is a term use

the United States and Canada to describe a type of wpollution control !istorically the term has referred au"iliary pollution controls in the #elds of industrial

wastewater control and municipal sewage control$ win stormwater management (both urban and rural) awetland management$ BMPs may refer to a principacontrol or treatment techni%ue as well (Wi&ipedia)

• Best management practices (BMPs) describe wamanage your land or your actiities to reduce or prepollution of surface and groundwater near you ,hespractices protect your family+s health$ but also help

,he discharge0disposal of industriwastewaters can

be classi#ed as follows-• Uncontrolled discharges to the enironment

• Controlled (licensed) discharges to the enironment (watercou

possibly after pre.treatment

• Illegal$ mostly clandestine$ discharges to sewerage systems

• Controlled discharges to sewerage systems under agreement o

licence$ possibly with pre.treatment

• Wastewaters collected by tan&er for treatment0disposal

elsewhere

• 6arious approaches to e'ectie industrial wastewatecontrol are aailable such as the use of appropriatetechnology (speci#ed$ for e"ample$ as the besteconomically aailable) or the issuing of 7permits8 or

7consents8 based on olumes and %uality standards fdischarges either to sewers or directly to watercour

• Insome countries (eg United States) pre.treatmentstandardsapply to all industrial users wishing to discharge to t

sewerage system (to control pollutants that may pasthrough orinterfere with the treatment wor&s processes or whimaycontaminate the sewage sludge)

• In others each discharge istreated on its own merits irrespectie of its general orclassi#cation$ and standards are set according to the
