SuDS system — Figueira da Foz
Sustainable drainage system (SuDS) with a capacity of around 400 m³ installed in Figueira da Foz. Hidrostation supplied the polypropylene HidroCrate 45T modules and provided on-site engineering support during assembly. The modules sit on a base wrapped in geotextile, with integrated inspection chambers for maintenance. Purpose: to retain rainwater and release it in a controlled way, reducing surface runoff and relieving the drainage network during heavy rainfall events.
Grease separator — RoTerra 50.000L
Delivery of a 50.000-litre RoTerra 2450 underground tank that will operate as a grease separator. Made of HDPE, around 10,85 metres long and 2,4 metres wide, with three Ø600 access points and telescopic shafts, it arrived on site in a single piece and was unloaded and positioned with an excavator. Its oval shape and reinforcing ribs give it the strength needed to be buried, and the lightness of polyethylene makes transporting and placing a volume of this size much simpler.
Rainwater harvesting — 3× RoDrive 40.000L at Porsche Centro Porto
Rainwater harvesting system with three 40.000-litre RoDrive underground tanks supplied to Porsche Centro Porto, for a total capacity of 120.000 litres. Each high-strength HDPE tank is around 8,5 metres long and has two self-levelling telescopic DN600 access shafts. Designed to be buried under traffic areas, they withstand truck traffic of up to 40 tonnes without a concrete cover slab — a light, quick-to-install solution for an urban site with limited space.
Rainwater harvesting — 2× RoDrive 65,000L
Rainwater harvesting system with two interconnected 65.000-litre RoDrive tanks, for a total of 130.000 litres. The two high-strength HDPE tanks, around 29 metres long as a set, were joined by PE d200 pipework welded by electrofusion, with DN400 inlet and outlet, a DN250 overflow and DN600 access shafts with cast-iron covers. Buried under asphalt paving, they withstand truck traffic of up to 40 tonnes without a concrete cover slab.
Attenuation system — Polytechnic of Coimbra
Stormwater attenuation system with a capacity of 56 m³ installed at the Polytechnic of Coimbra. Made up of HidroCrate 45T polypropylene modules assembled on site, wrapped in geotextile and fitted with integrated inspection chambers for maintenance. Purpose: to temporarily retain rainwater and release it in a controlled way, relieving the drainage network during heavy rainfall.
Flexible Tanks — Waking Life Festival
Installation of flexible tanks for the Waking Life Portugal festival. Total capacity: 30.000 litres of non-potable water, 50.000 litres of non-potable water and 30.000 litres of drinking water.
SuDS system — Foz do Arelho
Sustainable drainage system (SuDS) with a capacity of 50 m³ installed in Foz do Arelho. Infiltration and attenuation system made up of approximately 180 units, wrapped in geotextile and fitted with an inlet filter. Purpose: to attenuate and infiltrate rainwater, reducing surface run-off and supporting aquifer recharge.
SuDS system — Cadilhe dos Santos
Sustainable drainage system (SuDS) with a capacity of 26 m³ at the Cadilhe dos Santos premises. Made up of approximately 100 units, with an inlet filter and geotextile. The system is fully operational, with satisfactory results in reducing surface run-off.
30m³ underground water tank
Installation of a 30m³ water tank buried directly in the ground, with an installation time of just 1 day. Built in high-density polyethylene (HDPE) — light, strong and easy to handle. The telescopic covers allow a quick finish with an excellent final result. The 30.000 litres of water are available to make up for water shortages during the driest periods.
Infiltration system — Ponta Delgada Hospital
Sustainable drainage system installed at Ponta Delgada Hospital in partnership with the company Sousa e Garcês. This installation helps reduce the impact of heavy rainfall and protect the environment, preserving the natural permeability of the ground.
Rainwater harvesting system — Cercipeniche
Supply of a 10.000-litre RoTerra rainwater harvesting system to Cercipeniche, an institution supporting people with disabilities and/or difficulties with adaptation and social inclusion. Estimated annual water reuse: 500.000 litres.
Rainwater tank — RoTerra 2×12.000L
Installation of a rainwater harvesting system with 2 RoTerra tanks in HDPE, with a total capacity of 24.000 litres. The system has mesh inlet filters (down to 0,35mm) for garden irrigation, washing paved areas and toilet flushing.
