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.

■Deep wellThere are 4 types of water intake screens for deep wells to suit different uses.
Among these, the "Ring Base Screen" is a screen that has earned high trust in terms of its aperture ratio and strength.

■High aperture ratioBecause Nagaoka Screen has a high opening ratio, it is less likely to become clogged and has approximately 10 times the water intake efficiency compared to strainers such as slit pipes. The slot width (gap) of the screen can be freely designed to suit the aquifer, making it possible to meet a wide range of market needs.

■High strengthDue to its high strength structure, it is strong enough to withstand deep installation depths, is resistant to earthquakes and other disasters, and is resistant to rust.

■Sand control technology"Sand control technology" that only takes in water without moving the sand in the sand layer around the screen prevents clogging and enables 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.
