Nacala Boreholes, Transmission Mains, and Distribution Centres | Nicholas O’Dwyer 

November 10, 2020/in Environment, Water Resources

Project Title: 

Nacala Boreholes, Transmission Mains, and Distribution Centres | Nicholas O’Dwyer

Location:

Nacala, Mozambique

Client: 

Fundo de Investimento e Património do Abastecimento de Água (FIPAG)

Business Sectors: 

Environment, Water Resources

Services (Technical Disciplines):

  • Preliminary Design
  • Detailed Design
  • Tender Dossiers
  • Procurement
  • Construction Supervision

Project Objectives/ Outcomes: 

The Nacala water supply distribution system is supplied by two sources. The first source is a dam on the Muecula River some 30 km south west of the city. The reservoir has a storage capacity of about 4.4 million m³. The dam was rehabilitated and raised to expand the capacity of the reservoir to facilitate a supply increase from 7,200 to 10,000 m³/day.

The second source for the distribution system is the Mpaco and Mutuzi (I and II) well fields. These well fields have a total of ten boreholes with flows between 1,080 and 2,400 m³/day each, resulting in a combined capacity of 13,920 m³/day. Further groundwater investigations indicated that the sustainable capacity of this second source was 23,000 m³/day. This project provided for the construction of the following works: Development of 22 No. Borehole sources together with collection systems; 2 No. 200m³ RC collection reservoir and 1 No. 100m³ RC collection reservoir; 4 No. High lift Pumping stations; Approximately 10km of 350mm and 17km of 200mm transmission mains; 2,000m³ service reservoir and 250m³ water tower; Extensive mechanical and Electrical works.

Our Role:

  • Preliminary and Detailed Design of Groundwater Abstraction Systems, pumping stations, Transmission Mains
  • Design review of Distribution Centre and Water Tower
  • Preparation of Tender Dossiers
  • Review the Environmental Management Plan (EMP) prepared by the Contractor
  • Supervision of the construction, commissioning and hand-over of the Schemes
  • Monitoring the Contractors design progress in accordance with the Contractual Programme
  • Instructing and monitoring the Contractor regarding compliance with health and safety precautions
  • Review of payment applications and approval of all eligible payments for the Employers action
