Architecture & Engineering – Elite zero-edge pool engineering in Bahrain

Balancing engineering and entertainment

Completed in 2007, this ambitious project marks a major milestone for us as international infinity pool designers, representing our very first – but certainly not last – zero-edge installation in the Middle East. The brief for this private resort in Bahrain was exceptionally ambitious. The client – a prominent local businessman who pioneered major regional developments – required an aquatic complex capable of handling heavy bather loads during large events without sacrificing architectural elegance.

The estate’s courtyard presented a dense grove of mature palm trees and a varied topography that ruled out a standard rectangular layout. Rather than clearing the landscape, the design evolved into a 20-metre free-form pool whose irregular contour wraps around the existing trees, drawing its shape directly from the site.

That sinuous perimeter produces the property’s defining feature: 60 linear metres of zero-edge detailing. In the arid, high-temperature climate of the Middle East, engineering an overflow channel of this scale requires absolute mathematical precision to maintain an unbroken water horizon that mirrors the sky. The complex operates as a unified private resort experience, integrating a dedicated children’s lagoon, a circular spa, and a private hammam facility directly adjacent to the main terrace.

Overcoming extreme coastal conditions

Building an overflow pool in Bahrain means confronting severe environmental constraints. The site presented a high seawater table, highly corrosive salt air, and summer temperatures regularly exceeding 50 °C.

During excavation, excessive seawater infiltration required an immediate redesign of the structural foundations. The engineering team added specialised waterproof membranes and advanced sub-base drainage systems to isolate the concrete shell from the aggressive water table. The extreme salinity of the local water supply also dictated a complete upgrade of all mechanical components. Standard valves and pipe connections were replaced with marine-grade specifications to prevent long-term corrosion.

Craftsmanship at the overflow edge

Achieving a perfect mirror effect across a 60-metre free-form perimeter demands exacting craftsmanship. Any deviation greater than 1 mm at the overflow lip would interrupt the continuous sheet of water. The local contracting team worked in precise sections under close supervision by Morana, using laser levels in the early mornings when wind conditions were perfectly still.

The custom overflow slot detail was executed by cutting 3 cm-thick granite slabs on-site to match the exact radius of the pool’s curves. Two separate granite coping stones conceal the gutter, leaving a 1 cm gap between them for the water to disappear flush with the deck.

Modular filtration and hydraulic strategy

High-end pool architecture relies entirely on invisible engineering. Where a standard approach might use a single oversized pump, this project employs a modular configuration with three separate 25 m³/h units operating on a single filtration circuit.

This multi-pump strategy offers three operational advantages:

• Energy efficiency – during cooler, quiet months the estate managers can shut down one unit to reduce energy consumption.
• Peak capacity – when hosting large events all three pumps run simultaneously to manage the higher hydraulic demand.
• System redundancy – if one pump requires maintenance the remaining units keep circulation and the overflow functioning, avoiding a total shutdown.

The balance tank was sized strictly on the cumulative pipe-return volume – the quantity of water that flows back into the pool when the pumps stop and the hydraulic circuit drains. This approach replaces the common but unreliable method of estimating surge from bather displacement, and ensures the tank absorbs the full returned volume without overflow or air ingestion at pump restart.

International project management from Europe

Morana’s 18-month presence in the Gulf region provided first-hand knowledge of the local supply chains, construction practices, and climatic constraints specific to the Middle East. That operational experience directly informed every technical decision on this project – from material specifications to site scheduling around extreme summer temperatures.

The hydraulic network and structural details were designed from Europe, with ultra-detailed technical drawings at millimetre-level tolerances serving as the sole reference for local construction crews. A targeted logistics strategy addressed regional import constraints: local contractors handled material procurement, while high-end technical components were sourced through a professional distribution platform in Dubai. Morana supervised the critical construction phases through timed site visits, covering the structural pour, the mechanical integration, and the final commissioning of the automated systems.

The complex has operated continuously for over two decades with no structural intervention – a direct result of the upfront engineering rigour applied to every detail from foundation to overflow edge.
