Extra efficient cleaning without external water supply, with or without external power. Made of stainless steel and the plants are nearly maintenance-free. Flushing lanes in tanks up to 120 m as well as flushing lanes in channels up to 200 m have been built.

The NEUHOLD rainwater infiltration system consists of light-weight, plastic, semi-circular shells with the capacity to buffer and infiltrate rainwater from sealed surfaces into the ground. The semi-circular shells have a 100 % buffering capacity and compared to gravel, the infiltration ditches need less than 1/3 of conventional space. Rainwater can pass freely through the bottom and infiltrate the ground through holes in the side of the tunnel.

Stops unpleasant odour, high reliability because of use of high-quality material (stainless steel and high-quality plastics PE-HD). high durability of filter material (if required, filter material can be changed - this will be necessary after approx. 5 years). No tool necessary for installation, complete sealing between filter and sewer manhole by the sealing at the outside of the filter.

NEUHOLD backwater flaps are used in connection to surface, sewer and process water systems.Water discharging from the pipe opens the flap, however when the head increases on the downstream side, the flap is pressed against it`s seal, preventing backflow. Backwater flaps require only a small head in the pipe to open the flap, as HDPE floats in water - the backwater flaps are fitted with a counterweight to balance the flap correctly.

Our flood protection walls are made of aluminium alloy for the application for fixed walls, or mobile walls and they are designed for easy and simple installation and dismantling.
