Project Description:

Damage assessment and proposal for rehabilitation works of the capital city water supply system

  

Main Features:

MAIN STRUCTURES:

  • No. 5 intakes from spring

  • No. 70 main wells

  • No. 2 treatment plants

  • No. 19 urban storage tanks

  • No. 22 pumping stations

  • Supply network (L = 50 km)

  • Distribution network (L = 1'170 km)

 

PRE-REHABILITATION:

  • Water resource = 250'000 m³/d

  • Network losses = 60%

  • Supplied population = 1'700'000 inh.

  • Per capita water consumption = 60 l/cap/d

 

POST-REHABILITATION:

  • Water resource = 350'000 m³/d

  • Network losses = 35%

  • Supplied population = 1'800'000 inh.

  • Per capita water consumption = 120 l/cap/d

  

Engineering Service:
  • Inspection of the intakes and of the main supply structures

  • Inspection of the pipelines in the areas of visible losses

  • Hydraulic study of the network in order to divide the whole area in hydraulically homogeneous systems

  • Identification, programme and cost estimation of the rehabilitation works

  • Supervision during rehabilitation works
