Project Title:

Mbarara Water and Sanitation Project (Design) | Nicholas O’Dwyer

Location:

Uganda

Client: 

National Water and Sewerage Corporation

Business Sectors: 

Water Resources/ Environment

Services (Technical Disciplines):

• Feasibility
• Preliminary Design
• Detailed Design
• Tender Dosiers

Project Objectives/ Outcomes: 

The project involves the detailed design, preparation of tender documents, procurement and construction supervision for works to the existing water and sanitation infrastructure in Mbarara in western Uganda. The project is being delivered in two stages; Stage 1 is Detailed Design and Stage 2 is construction supervision.

In terms of Stage 1 the scope of the Detailed Design includes the following works;

• Rehabilitation of the existing Water Treatment Plants at Kabale road in Mbarara (capacity of about 5,000 m³/day),
• Rehabilitation of Ruharo intake and WTP (existing capacity of about 8,000 m³/day) and extension with a new line of 8,000 m³/day,
• Rehabilitation (including NRW reduction through implementation of DMA), intensification and extension of the distribution system in Mbarara service area,
• Detailed design of approximately 20km of trunk and distribution mains ranging in size from DN150 to DN300.
• Upgrade and rehabilitation of approximately 10km of sewer networks within 3 catchments including 1 Nr. Pumping station.
• Detailed design for upgrades and rehabilitation to existing waste stabilisation ponds in the catchments of Katete, Kakoba and Kizungu.
• Detailed design for new faecal sludge treatment centre and associated effluent treatment.

Nicholas O’Dwyer carried out all civil, structural, process, mechanical and electrical designs for the water and sanitation infrastructure. An ESIA and RAP study was also carried out for the project. Procurement of the works contracts will be through FIDIC Red conditions of Contract. Nicholas O’Dwyer will provide the key experts for the management and supervision of the works which have an estimated value of $35m.

Our Role:

• Review and update of Preliminary Designs
• Detailed Design of Water and Wastewater Improvement Works
• Preparation of Tender Documents (FIDIC)
• Assistance during the Procurement Stage
• Assistance in preparation of ESIA and RAP
