Meme­lakha land­fill chal­lenged with leak­ages of leachate

Although the ex­ist­ing Meme­lakha land­fill has reached its sat­u­ra­tion point but the Thim­phu Thromde of­fi­cial said that it will not re­lo­cated the land­fill else but will rather ex­tended the ex­ist­ing land­fill with con­struc­tion of leachate tanks.

Along with the waste in the land­fill, the big­gest chal­lenges faced by the land­fill are the leak­ages of the leachate ( the black wa­ter) which is com­ing from the waste. Thim­phu Thromde, Chief Envi- ron­ment Of­fi­cer, Mr. Tsh­er­ing Pen­jor, said that be­cause the land fill is lo­cated in the gorges and two hill slopes are con­verg­ing at the base, so all the rain wa­ter are con­nect­ing to the waste dump­ing site. That’s way there are lots of leak­ages of leachate.

For that he added that in col­lab­o­ra­tion with Ja­pan En­vi­ron­men­tal and San­i­ta­tion Cen­ter ( JESC), the Thim­phu Thromde has con-

structed four leachate tanks and gabion wall to pro­tect the waste fol­low­ing down­stream, small san­i­tary land­fill, black topped the ap­proach roads to­wards the land­fill. The pro­ject was han­dled by JESC.

In the south of the land­fill with one tank which did not serves the pur­pose , the Thromde has had dug one pit ad­ja­cent to the ex­ist­ing land­fill, which also could not serve the pur­pose which is next to the road side now have con­structed the another RCC cham­ber. The of­fi­cial added that with this mech­a­nism put in place this year his year the leak­ages of leachate will not fall on the road.

In the north another 1, 50,000 liter ca­pac­ity of tank has been con­structed. “The leachate gen­er­ated from the waste is not a re­ally prob­lem but over­flow be­ing trig­gered by the rain es­pe­cially dur­ing the sum­mer sea­son, that’s the big­gest prob­lem”, said the Chief En­vi­ron­ment of­fi­cer added.

But with re­gards to the re­lo­ca­tion of the land fill, through this pro­ject, small area ad­ja­cent to the ex­ist­ing land fill which will serve the dual pur­pose of re­in­force­ment wall of pre­vi­ous land­fill and land­fill as well.

Through the study done by the Ja­pan In­ter­na­tional Cor­po­ra­tion Agency ( JICA), it shows that the ex­ist­ing land­fill can be ex­tent pro­vided the Na­tional En­vi­ron­ment Com­mis­sion (NEC) pro­vides the nec­es­sary clear­ance as NEC clear­ance is manda­tory and nec­es­sary.

Mean­while, he also added that the Thromde has started op­er­a­tion of the trans­fer sta­tion at Ngabe Rongchu which will re­ally re­duce the waste load of the ex­ist­ing land­fill.
