And the production of leachate was 0.8 m3 / day. Levels of waste treatment unit COD= 8960mg / l and BOD5 = 3968.293 mg / l, after going through the waste treatment plant to be COD= 298.67 mg / l and BOD5 = 88.18 mg / l. From the processing of these three levels in an alreadymeets the standard group III cross section pond 03/91.Keywords : Water leachate , storage ponds , COD and BOD5.]]>
