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

Wet Processing Plant Design

Project Outcomes/Objectives

The land surrounding AuVert’s Condoto site is rich in precious metals. Formerly mined for platinum, the old operation did not fully maximize the resources onsite so precious metals remained in the ground, something AuVert wanted to capitalize on with its new wet processing plant.

The AquaCycle™ water management system recovers up to 90% of the water used throughout the process. On average, the CDE and AuVert approach uses 77% less water than traditional methods, without using any toxic chemicals.

This ensures the water supply won’t become contaminated and unsafe for the neighboring community. The AquaCycle™ and EvoWash™ technology has also provided flexibility to enable the plant to process variable clay-bound feed material with a high percentage of fines.

Our Role

At the front end of the process, AuVert employs the world-class R2500 – a durable hopper, feeder, and scalping screen which conditions the feed material prior to further processing by breaking down tough clay-bound materials and scalping large boulders to provide a consistent feed to the processing plant optimizing production throughout.

It also employs the AquaCycle™ thickener water management system for water storage and recirculation around the plant, which is needed for this remote location in the Colombian jungle.

The tail end of the process features CDE’s flagship EvoWash™ technology – a compact, modular materials washing system which integrates a high-frequency dewatering screen, sump and hydrocyclones to provide unrivaled control of the slimes cut point.

Project Outcomes/Objectives

Detailed Design and Construction Supervision of Water and Sewerage Networks in the towns of Chingola, Chililabombwe and Mufulira within Zambia’s Copperbelt Province. The project will ultimately serve an estimated population of about 1.1m inhabitants. The services were executed in two phases:

Phase 1: updating existing outline designs; carry out detailed designs for the agreed technical options and obtaining necessary permits; providing detailed cost estimates; preparing the technical content of the Bidding Documents for the selection of a 3 no. works Contractors for the Rehabilitation and Expansion of the Water and Sewer Networks; preparing 3 no. FIDIC Red Book Contract Documents and supporting the evaluation of the technical aspects of bids. The detailed design includes 67km of bulk water pipelines, 133km of water reticulation network, 87km of sewerage network, 6 no. pump stations and 22 no. reservoirs.

Phase 2: Construction supervision of the above.

Our Role

Environment Impact Assessment (EIA)
Surveys (Topographic and Geotechnical)
Detailed designs of water networks and sewer networks
Preparation of Tender Dossiers (to EIB Standards)
Procurement of Works Contractors
Contracts Management and Site Supervision

Project Objectives/Outcomes

The Lusaka Sanitation Program aimed to increase access to sustainable sanitation services to Lusaka’s residents especially the urban poor and strengthen Lusaka Water and Sewerage Company’s (LWSC) capacity to manage sanitation services.

The program aims to address one of Zambia’s most binding constraints to economic growth through infrastructure investment in Lusaka, the rapidly urbanizing capital.

There were 3 components to this project:

1) CSE-08: Collection System Expansion Emmasdale and Chaisa, Ngwerere Sewershed – Construction of 18 km of gravity sewers of diameter 160 to 500mm.

2) CSE-23: Collection System Expansion Kafue Road, Manchinchi Sewershed – Construction of 10 km of sewers of diameter 160 to 500 mm and 3 No. pump stations and provision of access to sanitation to 132 No. commercial enterprises.

3) CSU-05: Upgrade of Ngwerere West Interceptor, Ngwerere Sewershed – Construction of 4 km of sewer interceptor of varying diameter.

Business Sectors

Services (Technical Disciplines)

CDM Smith engaged UtilityAR to provide wearable technology and a software platform in the form of smart glasses. The smart glasses allow users to access information that they need to complete their work and to link them with specialist colleagues and advice when needed.

Augmented Reality smart glasses can project information onto the inside of the lens of the glass to allow the wearer to see it while still seeing the real world. The integrated forward facing camera allows for video and image capture.

Project Objectives/Outcomes

CDM Smith explores ways to engage field staff with senior specialists. With a global workforce it can be challenging from a time and expense perspective for specialists in different locations across the globe to travel to site and advise less experienced staff. The use of the forward facing camera on the smart glasses allows a staff member on site to communicate with a specialist anywhere in the world. The specialist sees what they see and can provide advice/instruction and discussion on best practice/next course of action. The specialist can even provide on-screen mark ups to assist with clear communication.

Our Role

CDM Smith now routinely use the smart glasses on the majority of its sites to provide a more efficient service to its clients, to contribute to its quality management systems and to assist with staff engagement across the company.

The glasses are particularly useful in times or areas of restricted travel. In addition their use can be quantitatively assessed in terms of their carbon offset where travel to site from different parts of the world is no longer necessary (in some use cases).
