Supporting a Safe, Clean, Sustainable Supply of Water

Water scarcity and resilience issues are affecting utilities more than ever.  We offer companies expertise in securing and protecting water supplies as well as addressing existing infrastructure and operations via a multi-disciplinary approach.  Our interconnected network of over 250 experts located in Ireland, the UK and the Middle East brings together diverse skills, experience and insight, to turn obstacles into sustainable solutions.

The provision of potable water, the treatment of wastewater, drainage networks, tunnelling and conveyance and resource management are the core competencies of the Ayesa water engineering group.  We work with government agencies, municipalities, water utility companies, industry regulators and contractors to develop specialised solutions for large infrastructure projects.  We approach complex infrastructure projects by applying holistic assessments incorporating multiple factors, including catchment area, existing assets/service performance, demand variance, socio-economic and environmental constraints and opportunities, stakeholder management, and the presence of appropriate governance and regulatory control systems.

At Ayesa we are looking for opportunities to add value – we innovate,  increase efficiency and improve resilience and maintenance.  Whether that is collaborating across stakeholders, combining our collective expertise to find economies of scale or improving design concepts to add efficiencies and value.  Our aim is to connect across project stakeholders creating a teamwork culture, where safety is paramount and we always strive to understand the project from the client's point of view.  

Whether it’s designing pump stations buried deep within the ground, or building in complex terrain, designing storm tunnels in busy urban centres, flood mapping for prevention and planning, you will find Ayesa engineers striving to make that difference.
