The weather conditions in southern Poland were favorable, so the NPI welding team traveled there to line a basin. The basin, a newly dug basin, belongs to a Polish tomato producer who has multiple greenhouse locations across the country. They grow tomatoes on a total area exceeding 75 hectares. Their greenhouses at this specific location cover 45 hectares of which 39 hectares are for illuminated production. They primarily cultivate raspberry tomatoes, along with plum and cherry tomatoes, as well as seasonal cucumbers.
Water shortage
During the summers, the facility consistently faced water shortages. While a few water tanks were installed, they couldn't hold enough water to irrigate the greenhouse tomatoes during the hot and sometimes dry Polish summers. Therefore, a basin in the shape of a triangle was installed, with each side measuring over 200 meters.
Lining materials
NPI lined the basin with a total of 35,600 m2 of ENPEX FPP 1.00, divided into 15 film sheets that the NPI team welded together on site. But first, the basin was lined with 250 grams of protective felt. This felt aims to protect the film from sharp objects in the ground, such as twigs and stones.
Bank protection
After the film was installed, the NPI team also installed about 800 meters of geotextile as bank protection. Concrete tiles in ballast pockets in the sheets should keep the geotextile in place. According to NPI, it protects the film on the embankment from UV light, wind and weeds.
Tomatoes
The facility will primarily collect rainwater in the basin. The water will be guided via outlets to their irrigation system and facilitates irrigation of the tomato plants. The NPI team highlights that these tomatoes can be found in the largest retail chains in Poland.
