Deep Expertise in Organic Waste and Sludge Treatment

In 2018, The World Health Organisation stated that "every dollar invested in sanitation will bring a six-fold return in lower health costs, increased productivity and fewer premature deaths."  With this in mind and the introduction of several E.U. directives, the importance of cost-effective sanitation has never been higher. Ayesa has delivered wastewater treatment, storage, and conveyancing projects in Ireland, the U.K., and the Middle East. Our proven track record has helped government agencies, municipalities, utility companies and contractors develop and manage wastewater networks and treatment plants.  Ayesa currently sits on the framework for Irish Water, the national utility provider for Ireland. We provide detailed engineering services from concept through to commissioning, with expertise in whole-life costing and sustainable and energy-efficient design.  Our consulting services ranging from green/brownfield development of wastewater assets through concept design, retrofitting and process refinement. 

Our wastewater experts consult on the following:

  • Process selection and design
  • Wastewater treatment and optimisation
  • Wastewater pumping stations and conveyance
  • Wastewater Storage Design
  • Discharge licensing

We develop robust solutions that address existing and future challenges such as seasonal variance and headroom, tightening environmental restraints and specific industrial treatment requirements.  Some key projects for our water team include the Blanchardstown Regional Drainage Scheme, which serves a population equivalent of 150,000, the Arklow Wastewater Treatment Plant, that will provide treatment capacity of 24,000PE with potential to expand to 36,000 PE.  We are also providing process and civil design for a 37,000m3/d Industrial Wastewater Treatment Plant at the Jazan Industrial City development in Saudi Arabia, an economic city, based on the philosophy of symbiotic development in the Red Sea.
