Tenders Are Invited For Renewal And Rehabilitation Work On Sanitation Networks

Replacement Of An Asbestos Cement Sanitation Network With A Cast Iron Network Dn 200 Mm (203 Ml); Dn 400Mm (110Ml) And Dn 500Mm (16Ml). The Manholes Will Be Made Of Xa3 Concrete Dn 1000 Mm. Also Included In The Operation Is The Replacement Of 20 Asbestos Cement Connections With Pvc Connections Dn 160 Mm Having A Rigidity Class Of 16 Kn/M² And The Replacement Of The Connection Works With Direct Passage Stools In Pvc Or Pp Dn 315 Mm. Rehabilitation Of A Sanitation Network By Continuous Cladding In Dn 400 Mm (287 Ml) And In Dn 500 Mm (590 Ml) With Re-Lining Of The Manholes By Projection Of Hydraulic Mortar. The Project Also Provides For A Civil Engineering Service For The Replacement In Place Of A Custom Prefabricated Concrete Distribution Structure. Furthermore, It Should Be Noted That The Flow Rate Of The Western Network Is Very High (Around 700M³/H), Suitable Pumping Will Therefore Have To Be Put In Place In Order To Ensure Continuity Of Service.
