The Mérida Water Distribution Ring System

Ayesa performed the following work for this project:

A perimeter ring of 15.7 km in length, made from ductile cast iron, DN 600 mm, PN-16 (Class 30). A perimeter pump to provide pressure to the ring. A pump at Proserpina to replace the current pump, which was in poor conditions.

2.2 km-long piping from Proserpina, made from ductile cast iron, DN 500 mm, PN-16 (Class 30) A new reservoir at Proserpina, which can hold 5000 m3 of water and has a maximum water height of 4.5 m. N-V East and N-V West branch pipelines, both made from ductile cast iron, DN-400, and measuring 2.4 and 3.7 km in length. These take water from the ring and supply various urban areas in Mérida with water. The second branch pipeline also supplies the reservoir at Calamonte. Connections with Mérida's water supply network.

Unique features:

Jacking of 22 pipelines of between 10.40 m and 66 m in length to cross roads, railway lines, the San Lázaro Aqueduct and the Albarregas River channel. This was achieved by means of a metal pipe jacking system which used a rotating system with ø800 and ø1000 metal pipes.

The north and south crossings over the Guadiana River were achieved using directional drilling with polyethylene pipes. This involved the following characteristics:

  • South crossing: 354 m, ø713 PE/PN-16.
  • North crossing: 426 m, ø713 PE/PN-16.

Four areas of Mérida's water supply network with low pressure were identified in order to be supplied directly from this ring. For this purpose, 15 switching, by-pass and regulation chambers were built.

Current challenges and Ayesa’s solutions

Ensuring water management is sustainable and able to deliver enough water of adequate quality requires a multidisciplinary approach combining aspects such as hydrology, river hydraulics, quality and the environment. To do this, we use technology, innovation and software for simulating fluids and processes. In the hands of our experts, who cover all the fields involved in this area and seamlessly pool together their knowledge, these tools ensure we offer our clients services synonymous with excellence.

The trust our clients place in us is further strengthened by our outstanding track record as a technology-driven engineering company. We are constantly one step ahead and at the forefront of hydraulic engineering, something we achieve by using innovative techniques and having the very best people in the field. Our professionals are able to easily grasp and meet the unique needs of each project. Our solutions place the uppermost importance on respect for the environment and always have a social purpose, something we believe all engineering projects should achieve.

Our expertise and technology

We bring our experience, expertise and technology to the entire water management cycle, from water planning through to operations and maintenance for all kinds of infrastructure.
Highly specialised multidisciplinary teams
Our teams are highly specialised in all areas of hydraulic and environmental engineering.They confidently take on new challenges, such as mitigating the effects of climate change and ensuring the sustainability of infrastructure.
Applied innovation
At Ayesa, we go to great lengths to offer the very best service. That’s why, over the past decade, we have worked hard to become a leading global pioneer in the development of infrastructure using BIM methodology in accordance with ISO 19650. This also allows us to include other emerging technologies in our designs, such as drones, artificial intelligence and big data.
Sustainability and efficiency
Sustainability is particularly important and a key part of our designs, our aim here being to minimise environmental impact and maximise energy efficiency. We also include life cycle analysis methodologies as well as environmental impact assessment and certification in our designs.
