"Mr. Water Turtle" is an easy-to-assemble tank that stores water for daily use and disaster prevention from a well pump. It can be assembled quickly since it only requires inserting the support poles. When folded, it becomes compact and does not take up storage space in your emergency supply warehouse. You can store water from a hand-pumped well at a disaster response base in the tank and then supply it to buckets or plastic containers. 【Features】 ■ Easy assembly: No tools required, just insert the support poles ■ Easy mobility: Sturdy design allows for smooth movement ■ Comes with easy-to-use water supply and drainage hose ■ Compact storage: Folds up to save space *For more details, please download the PDF or feel free to contact us.

• Rainwater tank

We would like to introduce the Tōtetsu Rainwater Diverter and Dust Removal Device "Bunryū Type I/II." Large visible dust and debris are removed by a strainer, while contaminants dissolved in rainwater are removed by diverting the initial rainwater and discharging it externally. The "Bunryū Type I" is primarily installed at the top of the tank or on the vertical downspout. If water needs to be sent to a distant tank or if the piping is at a higher position than the diverter, please use the "Bunryū Type II (standard type)." 【Features of Bunryū Type I】 ■ Debris such as leaf litter that flows down with the rainwater is removed by the strainer at the top of the main body, and finer dust is further removed inside the main body, allowing clean rainwater to be directed to storage tanks or infiltration pits. ■ No regular maintenance is required. ■ The water diversion rate can be adjusted as desired using the "knob." ■ Its compact size does not require a special location for installation. *For more details, please download the PDF or feel free to contact us.

• Rainwater infiltration facilities

- With a check valve - Maintenanceable - No metal used - Internal structure of the valve body

• Water and sewerage pipe fittings

- Equipped with a check valve - Maintenanceable - No metal used - Internal structure of the valve body

• Water and sewerage pipe fittings

- The structure is designed to minimize direct exposure of the valve body to ultraviolet rays, resulting in excellent durability. - The upper filter prevents the intrusion of sediment and protects the valve body. - Maintenance and valve body replacement are possible, and no metal is used.

• others

- The valve ball is designed to operate flexibly and sensitively without the principle of buoyancy and a fulcrum. - Maintenance is possible - the valve ball can be replaced and internal cleaning is feasible. - It has a large drainage capacity, so there is no need for multiple installations. - Combining the side drain pipe with a management chamber enables more advanced maintenance! → For details, please contact us.

• Water and sewerage pipe fittings

Maintenance possible - After installation on site, the canopy can be removed, allowing for internal cleaning and repair or replacement of the valve body (YS-100 is not maintenanceable).

• Water and sewerage pipe fittings

- Increase the drainage effect from the drainage hole - Prevent the outflow of backfill soil and reduce the likelihood of clogging - Prevent damage from rising water channels and frozen ground - Easy to install

• Water and sewerage pipe fittings

- Simple drainage device for waterways, retaining walls, and drainage holes - Due to its three-dimensional structure, it is less likely to clog and can be easily installed by simply inserting it into the drainage hole - Effective when retrofitting weep holes

• Water and sewerage pipe fittings

The "DV-50N/DV-75" is a backflow prevention valve for drainage that is resistant to functional failures and has excellent durability. It has a large drainage capacity, outstanding shut-off performance, and is easy to maintain. It can be adjusted in length and can also be installed retroactively. It discharges water from handball courts, utility ducts, and information boxes, preventing the intrusion of groundwater. 【Features】 ■ Simple structure ■ Resistant to functional failures and has excellent durability ■ Large drainage capacity and outstanding shut-off performance ■ Easy maintenance ■ Length adjustable ■ Can be retrofitted *For more details, please refer to the PDF document or feel free to contact us.

• Manhole body

The "YS50" is a float-type weep hole that ensures a strong and reliable seal on the valve seat due to the buoyancy of a special elastic float, eliminating concerns about water leakage. During dry conditions, the float completely detaches from the valve seat, allowing groundwater to be freely discharged. Since the valve seat is oriented downward, there is no risk of mud settling and hardening near the valve seat. Additionally, the operating components are built into the drainage pipe, preventing damage from impacts caused by flowing debris and theft due to vandalism. 【Features】 ■ Reliable valve operation ■ No negative pressure during groundwater discharge ■ No mud accumulation or adhesion ■ No risk of damage or theft ■ The elasticity and strength of the float and valve seat are stable with respect to temperature *For more details, please refer to the PDF document or feel free to contact us.

• Drainage and ventilation equipment

The "Bunryu Type I" removes leaf litter and other debris that flows down with rainwater using a strainer at the upper part of the main body, and further removes fine dust inside the main body through diversion. 【Features】 <Bunryu Type I> ■ Fine dust is removed through diversion inside the main body ■ No need for regular maintenance ■ The water diversion rate can be adjusted arbitrarily with a "knob" ■ Compact design does not require a special installation space

• Tunnel construction

【Features】 ■ Complete removal effect of initial rainwater and dust ■ Maintenance is easy as the management box can be placed at a low position on the ground ■ Compatible with almost all downspouts from small to large diameters * Obtained certification for rainwater retention and infiltration products from the Rainwater Retention and Infiltration Technology Association

• Rainwater tank

【Features】 ■Above-ground cylindrical tank ■No water retention area from which rainwater can be drained from the bottom of the tank, preventing sedimentation of mud and other materials ■Capacity can be increased by connecting two or more tank units ■We recommend using it in conjunction with our dust removal equipment.

• Outdoor storage, living room, and veranda unit

【Features】 ■ Tanks can be connected ■ The positions of the water level gauge, air vent, inlet, and overflow can be specified as desired ■ In the case of connected use, there will be one water level gauge ■ By using in conjunction with Bunryu Type I, Bunryu Type II, and pipe purification filters, higher quality rainwater utilization is possible

• Outdoor storage, living room, and veranda unit

Sandbag Station ■ Protects the city from disasters such as flooding under floors and above floors caused by heavy rain. ■ Also useful for preventing slips during snowfall. ■ Available for use by local municipalities. Garbage Station ■ No odors are trapped. ■ Stores securely when not in use, and provides cooperative support when in use.
