About This Product

■Nagaoka screen used everywhere・Groundwater is generally of good quality, has little change in water temperature, and has characteristics such as not requiring large-scale water storage or supply facilities for water intake.
・Widely used for domestic water, industrial water, agricultural water, etc.
- With the advent of wire-wound screens based on our proprietary technology, it has become possible to design water wells efficiently.
・In the field of groundwater intake, we have established the technology for Nagaoka-type water collection wells by leveraging our internal technology and know-how.
・Water intake from shallow wells and underground drainage canals can be significantly increased, and water intake can also be restored by repairing existing facilities.
- Screens for deep wells can be designed with opening widths that match the geological strata, and by using a ring-based screen with a high opening ratio and high strength, efficient and stable well drilling is possible.

■The optimal design matches the aquifer, allowing for stable groundwater intake due to its high strength and long life.・Water intake from the entire thickness of the aquifer
・Less water sampling loss and high water intake efficiency
・High opening ratio and extremely large water collection area
・Strong structure makes it resistant to earthquakes
・Slow inflow speed allows for long-term stable water intake

■2012 Water intake technology won the Excellence Award at the IWA-PIA World Convention and the Grand Prize at the East Asia Convention.In 2012, in the small project category of the International Water Association's (IWA) Innovative Technology Award System (PIA), the project to regenerate wells with reduced water intake, ``An optimal solution for water shortages using high-efficiency screens,'' was awarded the Honor Award ( (Excellence Award), won the Grand Prize at the East Asia Convention.
