Narrative description of Project:

  • Due to the dyna­mic deve­lop­ment of the Tuni­si­an eco­no­my, Tuni­sia is con­fron­ted with increa­singly important quan­ti­ties of was­te. In the com­ing years, it is esti­ma­ted a con­ti­nu­al increa­se of was­te quan­ti­ties of 4 to 5%.
  • In this con­text, KfW deci­ded to fund a new pro­ject “Inte­gra­ted manage­ment sys­tem for muni­ci­pal was­te in the Med­jer­da Val­ley”. Muni­ci­pal was­te inclu­des hou­se­hold was­te and assi­mi­la­ted sewa­ge sludge, slaugh­ter­hou­se was­te, indus­tri­al was­te, earth exca­va­ti­on and medi­cal was­te.
  • The aim of this pro­ject is to deve­lop and imple­ment a was­te manage­ment con­cept for muni­ci­pal was­te for the Med­jer­da Val­ley (area of 16,000 km²) for a time hori­zon of 20 years (collec­tion, trans­port, trans­fer, tre­at­ment and recy­cling, land­fil­ling). The pro­ject was divi­ded into 3 steps:
  • Pha­se 1: Cur­rent situa­ti­on ana­ly­sis (SWM sys­tem, eva­lua­ti­on of was­te data and was­te ana­ly­sis)
  • Pha­se 2: Con­cept stu­dy and design
  • Pha­se 3: Fea­si­bi­li­ty stu­dy and design for appro­val for two sce­n­a­ri­os (only land­fil­ling and was­te tre­at­ment with land­fil­ling)
  • Accord­ing to the stu­dy, the popu­la­ti­on in the pro­ject area in 2009 amoun­ted to approx. 647,000 inh­a­bi­tants for an annu­al was­te pro­duc­tion of 150,000 t / year. Until the year 2033, an increa­se of the pro­duc­tion of muni­ci­pal was­te to 253,000 t / year is plan­ned for a total popu­la­ti­on of 836,000 inh­a­bi­tants in the pro­ject area.
  • The fea­si­bi­li­ty stu­dy has com­pa­red two sce­n­a­ri­os: the first one con­s­i­de­ring only land­fil­ling and the second con­s­i­de­ring the tre­at­ment of was­te and land­fil­ling. Final­ly, the stu­dy has recom­men­ded the second sce­n­a­rio. This inclu­des the con­struc­tion of two new regio­nal land­fills at the sites of “Erro­u­ma­ni” in the nort­hern of the Med­jer­da Val­ley and “Les Sali­nes” in the sou­thern of the Med­jer­da Val­ley. In addi­ti­on two tre­at­ment faci­li­ties (MBT), one on each land­fill site, have been plan­ned for the tre­at­ment of the who­le was­te quan­ti­ties, and 38 trans­fer sta­ti­ons in the pro­ject area. Bet­ween 2014 and 2033, the plant of “Erro­u­ma­ni” will accept 2,461,072 tones of was­te and the plant of “Les Sali­nes” 1,713,623 tones. The cho­sen lining sys­tems for both land­fills is a com­po­si­te liner (com­pac­ted clay liner + HDPE geo­mem­bra­ne). Leacha­te gene­ra­ted of each land­fill will be trea­ted direct­ly on site.
  • The next step (Pha­se 4 expec­ted in 2014) will be the was­te sys­tem detail­ed con­struc­tion design for the land­fills and MBTs, the pre­pa­ra­ti­on of ten­der docu­ments (con­tract con­di­ti­ons, tech­ni­cal spe­ci­fi­ca­ti­ons, drawings, sup­porting docu­ments) and the assi­s­tan­ce with the award of con­tract.
