Piping layout and plant room plans for infinity and overflow pools
We produce the hydraulic and filtration drawings required to build infinity and zero-edge pools — piping layouts showing pipe routing,
inlet and drain positions, and plant room designs detailing equipment placement, valve sequencing and filtration sizing.
Why hydraulic and filtration drawings matter
In infinity and zero-edge pools, the visual effect relies entirely on the precision of the water circulation system. The overflow edge holds the water at an exact level — and even a small imbalance in the hydraulic circuit can disturb the surface and break the effect.
Construction drawings define the shape and levels of the pool. But without a detailed hydraulic plan, contractors cannot correctly position inlets, drains and return pipes, nor can they size the pump, filtration system and balance tank for the specific conditions of the project.
These drawings form the technical bridge between the pool structure and the equipment that allows the system to function reliably.
Pool piping layout
This hydraulic plan maps the complete network of pipes within the pool shell — from the position of each inlet, drain and vacuum socket to the pipe diameters and routing paths before the slab is cast.
For infinity and zero-edge pools, this drawing is particularly critical. The balance tank connections, overflow channel drains and return inlets must be precisely positioned to ensure even water distribution and a stable overflow line. A poorly routed pipe network cannot be corrected once the concrete has been poured.
Each pipe run is carefully planned to avoid crossings and overlaps — a precaution that helps prevent stress points in the network and potential pipe failure over time.
The different circuits — suction, return and overflow — are shown in distinct colours, allowing installers to follow the hydraulic network clearly and without ambiguity on site.

A well-designed hydraulic circuit is only as effective as the plant room that drives it.
Filtration system and plant room design
Filtration layout in the plant room — infinity pool with integrated spa, in-floor cleaning system and solar heating — Florida, USA. Client and project details have been removed for confidentiality.
The filtration drawing maps the complete system layout within the plant room (often referred to as the pump room in pool construction) — pump and filter positioning, pipe connections, valve sequencing, water treatment equipment, balance tank regulation and heat-pump bypass.
This plant room plan is produced at a scale of 1:20, allowing each component and connection to be clearly identified. Equipment is positioned in a logical sequence that follows the hydraulic circuit — from pool suction through filtration and treatment, to return — ensuring that the installation can be carried out without improvisation on site.
For infinity and zero-edge pools, the swimming pool filtration design must also integrate the balance tank regulation, the overflow circuit and the level control sensors. These elements are specifically detailed in our pump room design.
The result is a complete filtration system diagram that any qualified plumber or mechanical contractor can follow — regardless of their prior experience with overflow pools.
Beyond the drawings
Our construction drawings cover the structure, levels and edge details of the pool. The hydraulic and filtration plans complete the package — together, they give any construction team everything needed to build and connect an overflow pool correctly.”
We work with clients and contractors across Europe, the Middle East, East Africa, Southeast Asia and the Americas.
Our plans are designed to be used independently by any competent construction team. Where the project involves complex site conditions, an international context, or a team with limited experience of overflow pools, we are also available to provide technical support during construction.
