WATER AND WASTE WATER
Whether your business involves water resources, water supply or wastewater – we can provide you with innovative and sustainable solutions. Our dedicated consultants operate globally across all water industry sectors for all types of clients. Our consultants' capabilities include the investigation and development of water resources, the assessment of water needs and implementation of appropriate supplies, and the tractability and disposal of wastewater. We endeavour to involve stakeholders at all levels in the progression of water infrastructure projects. Our knowledge of the environmental impacts of water developments enables us to undertake projects that will improve the quality of life for beneficiaries – without damaging the environment. We deliver leading-edge services locally through our network of offices globally. From investment planning to operational support and design for capacity building, our water consultants support clients, including private investors, PLCs, and national and local governments in conflict zones and fragile and developing states.

Irrigation and drainage
We provide leading consultancy services to improve management of irrigation, drainage and water resources.
Our projects cover significant and small-scale developments, including new irrigation systems and the rehabilitation and modernisation of established methods. We closely match our well-proven technical skills with a sensitivity to agricultural, social, environmental, institutional and economic issues to develop sustainable irrigation as part of a coherent approach to improving rural livelihoods.
More important than the scale of the projects is their diverse nature. We are at the forefront of developments in participatory irrigation management through work on control of large-scale irrigation and drainage systems in Uganda, the development of economic and regulatory policy in Ghana, and on a smaller scale in Kenya and Ethiopia. We work with water users to ensure that irrigation is developed and managed to suit their livelihood strategies and takes complete account of their diverse interests.
Irrigation can be essential in poverty reduction, but this is only achieved if projects are well-managed and target the interest of vulnerable groups. We have undertaken a series of research studies to examine ways of improving irrigation management with the specific objective of ensuring that poor water users get reliable access to water – for whatever purpose they require – and can use this to improve their livelihoods.
We provide a comprehensive range of services, covering all stages in the project cycle, from identification through implementation to commissioning and future operation.
Weirs barrages
We undertake all aspects of barrage engineering including planning, site investigations, model and sedimentation studies, economic appraisal and outline design through to detailed design and implementation.
Rehabilitation
The rehabilitation of existing dams has become increasingly essential, and Halkin Group offers a comprehensive service to cover all aspects of this work.
Concrete dams
Halkin Group has been involved in the design and construction of many concrete dams throughout the world including conventional mass gravity structures and arch dam.
Wastewater networks
We deliver efficiencies through constantly developing new tools and processes to improve our services. We have automated many of our processes to ensure efficient outputs, and we utilize our internal project and program management systems to provide critical milestones are achieved.
We have built and verified numerous hydraulic models, varying complexity and size, with different drivers, project focus and catchment-specific requirements. Our models ensure the cross-fertilization of new ideas and best practices throughout. Our internal modelling procedures are regularly reviewed to ensure we utilize best practices.
Whilst we often undertake new model-building work, we must also adapt models from other organizations for future use. We have robust procedures to do this, assessing the condition of an existing model and highlighting any areas for improvement to suit the planned work and identifying risks associated with this. This allows the client to make informed decisions on, for example, future investment in survey work.
Typical work packages:
Existing model review – identification of data gaps and risk identification
Identification/planning of survey requirements (e.g. maintenance holes, CCTV including sonar surveys to determine sewer silt depth, topography, flow, impermeable area)
Procurement of survey work, including specification, on-site liaison/management and interpretation of survey data
Liaison with landowners, highway authorities and other third parties, including securing access permissions
Model verification, model improvements and upgrades
Identification of catchment needs, pioneering and solution modelling
Water quality and river impact modelling
River engineering
Environmental issues are always considered during the design process, and steps are taken to reduce any undesirable impact a scheme may have.
Much of our river engineering experience has been in relation to the study, design and implementation of flood alleviation schemes in fluvial and tidal environments. Our river engineers have worked on diversions, river training works, scour protection at bridges, river amenity improvements, river flow gauging stations and flow control structures. Our in-house experts in hydrology, hydraulic modelling, environmental impact assessment, and landscape design work closely with our hydraulic engineers in developing river engineering works.
