Capability Statements

Water Supply and Sewerage

Water projects are an integral part of a nation's infrastructure and strongly influence aspects of planning and development. Through our wealth of knowledge in the fields of mechanical, electrical, and hydraulic engineering, and public health works, we are well positioned to deliver projects in this sector.

Our main areas of expertise include.

Structural systems, analysis, and design.

Infrastructure, public utilities, and municipal services.

Water supply and distribution.

Sanitation, sewerage, wastewater treatment, and disposal.

Stations, substations, and plants.

Infrastructure management, operations, and maintenance.

Cost planning, estimating, and budgeting.

Investment programming and implementation

Master planning and the assessment of future water development schemes are carried out by our planning team. Providing services from regional master
planning for the optimization of water supply to assessing the environmental impacts of a wastewater disposal facility, the team provides the expertise to
form a balanced evaluation of proposed projects.

 

Our long history in designing and supervising major water supply and wastewater projects is complemented by our ability to provide environmental services.

 

We are able to call upon our expert team of professionals equipped with state-of-the-art equipment to undertake detailed water quality assessments as part of a wider package of environmental studies. In particular, we have developed our expertise in the field of industrial water treatment. The findings of our environmental studies have played a significant part in the development of
water treatment facilities. For example, consideration of wind direction has influenced the location and design of sewage treatment works.

Water Treatment Plants

Our experience in designing water treatment plants covers the whole water treatment cycle from the transmission of water from water sources and reservoirs, the treatment plant, and dissemination via water distribution networks. Our specialist water treatment engineers can advise on water treatment techniques including clarification, filtration, desalination, water softening, flocculation, sedimentation, disinfection, chlorination ... etc. Our design solutions range from large national treatment projects i.e. greater than 1000 cu m/d to local plants serving smaller facilities. These include smaller industrial and domestic units such as light industry and food manufacturing. We understand that the needs of our clients can vary considerably depending on the end-use of the water and take this into consideration
in our designs. For example, many of our clients have different water quality requirements in terms of safety and the impact on the environment.

Sewage Treatment Plants

ACE has been involved in a number of high-profile sewage treatment plants, including the Greater Cairo Wastewater Project. Providing a multi-disciplinary team of environmental, structural, M E P, and hydraulics engineers, ACE played a significant role in rehabilitating the existing collection and conveyance system and upgrading the treatment process to meet current regulations. ACE was responsible for the environmental assessments and also provided construction supervision and management for EI-Gabal EI-Asfar wastewater treatment plant on the east bank of the Nile. The project handles an average daily flow of one million cubed meters per day with provision to increase this to three million cubed meters per day, by successive phases.

Pumping Stations

Our experience in designing pumping stations ranges from large municipal facilities such as those required for the Greater Cairo Wastewater Project, to modest developments associated with smaller residential developments. The complexity of the pumping station depends on the predicted flow that is anticipated. In designing any pump station, our engineers take into consideration, capacity, cost and ease of installation, and future maintenance requirements.

Transmission Pipelines and Distribution Mains

Transmission pipelines and distribution mains are fundamental to any water network. Using modeling the software we are able to predict flow rates through
each segment of a pipeline or network. The design of the transmission pipelines or distribution mains takes into consideration key factors including predicted
demand, local topography, soil conditions, and the requirement for pumping and gravity flow systems. 0 ur services cover the whole process of water transmission and distribution, from water collection across a catchment area to delivery to an individual property.

 

In Libya, we have installed water systems across the cities of Murzu q, Fun qui, and Tragen. ACE delivered the engineering design for pipes ranging in size from 90
mm to 300 mm, valve chambers, and connections to individual households.

ACE has provided the engineering design for new sewer systems as well as upgrading existing systems. Services include the design of the collector main, pumping stations, manholes, and delivery to the treatment plant. Large-scale infrastructure projects include sewage systems for the Orikum, Tragjas, and New Dukat villages along the Radhima coastline of Albania. This consisted of 29.9 km of collector mains with manholes, pumping stations, and a sewage treatment plant with a capacity of 8,000 m3 /day.

Storm Drainage

We have also completed a number of storm drainage networks. Designing for typical storm return periods our team has developed new networks and has
rehabilitated existing drainage systems. Detailed hydrological studies taking into account, local topography, geology, climate, and land use enable our engineers to develop drainage schemes that will protect communities from future flooding. Our experience in designing tunnels, culverts, and drainage pumping schemes enables us to tailor the design to meet local needs.

 

We have recently undertaken a number of projects in Uganda rehabilitating existing drainage channels. In Kampala, we have worked with our bridges, highways, and utility teams to develop a solution where the Lubigi Channel passes under existing highways and crosses utility corridors. As part of this program of works ACE was required to undertake a technical review of the channel stabilization techniques being proposed.

 

Throughout the project, ACE monitored the contractors' involvement to ensure that all design specifications were met.

Project Experience

Gunjur Water Treatment Plant -Gambia

A simple self-contained water supply system was designed to provide a good quality source of domestic water in sufficient quantity to meet the demands of the local population. Water requirements for agriculture, commercial use were also considered. The
water supply system including the construction of a Simple water treatment plant, Elevated storage tanks, a generator and pump station, and a distribution network. ACE was responsible for the design, tender process, and site supervision.

Greater Cairo Wastewater Project - Egypt

As part of a massive project to upgrade Cairo's wastewater system, ACE has provided a range of services from environmental impact assessments, design review of treatment plants, pumping stations and sewers, and construction management. The project included the rehabilitation of the existing collection system, building a new collection and conveyance system to expel sewage away from the city, improved wastewater treatment to meet
contemporary standards, and the reuse of treated wastewater providing sludge as a soil
conditioner/fertilizer.

Water Supply and Sanitation Project - Orikum, Albania

The project scope included civil works and procurement of associated equipment related to the construction of the water supply network and sanitation facilities in the project area. The Water Supply System included the construction of over 50km of water transmission distribution lines, water wells, water intake structures, pumping stations, storage reservoirs, and house connections. The Sewage Collection System included lying of sewerage collection networks comprising 29. 9 km of collector mains with manholes, pumping stations, and a sewage treatment plant with a capacity of 8,000 m3 /day. ACE provided site surveys, detailed design, tendering process, construction management, and defects liability monitoring.
