About

Project Overview We are developing Fishing Heaven Resort in Málaga, Spain — a pioneering eco-tourism and sportfishing destination. Phase 1 includes a 90 × 40 m exotic fishing lake inside a 100 × 60 m dome, supplied by a hybrid RAS (recirculating aquaculture system), rainwater harvesting, thermal buffer tanks, and smart refill systems. All technical infrastructure is above ground and must integrate seamlessly with heating, PV, and AI control. What We Need We are seeking a Plumbing / Water Systems Designer to create coordinated designs for: • RAS piping (2 × 200 m³/h lines with redundancy) including pumps, valves, filters, oxygenation, and degassing. • Thermal buffer integration (2 × 100 m³ tanks) with CO₂ heat pumps and under-lake heating grid. • Rainwater harvesting system (50,000–100,000 L tanks, UV disinfection, booster pumps). • Preheated well water buffer with geothermal/heat pump coil. • Overflow, drainage, and sludge discharge management. • Plumbing layouts integrated with dome structure and architectural drawings. 5+ years’ experience in plumbing/water systems design (industrial, aquaculture, or resort projects). • Proficiency with AutoCAD MEP / Revit / Plant 3D or equivalent. • Strong knowledge of pumps, filtration, water treatment, and pipe hydraulics. • Ability to deliver clear drawings and specifications for construction. • English communication skills. Nice-to-Have • Experience with RAS (recirculating aquaculture systems) or aquaculture water management. • Knowledge of renewable energy integration (heat pumps, thermal buffers). • EU project documentation familiarity.
