The problem

Modern canal networks should be managed according to the requirements of the operator. An increasingly important factor is the cost-performance ratio. In individual cases a business management analysis is called for. Most of the currently available systems provide very expensive overall solutions, which seldom allow for effective and inexpensive technically independent partial installations. It is not always appreciated that the technology necessary for overall solutions often involves large constructions. Successive expansion is a much better option than an “all or nothing“ decision.

The solution

HydroGuard® is not only a product but also a system for the complete management of large canals, whole canal networks as well as for individual canal sections.
HydroGuard® provides inexpensive partial solutions without compromising on function.
HydroGuard® performs many different functions and can be easily adapted and/or modified to meet the operational requirements for the management of single canals or whole networks. The main areas of application include controlled impounding and storage processes as well as the temporary detention of discharges with subsequent utilization of the impounded water for flushing the canals. An adjustable bottom outlet opening enables a continuous transfer of the pollution load to the treatment plant even during impounding.
HydroGuard® offers enormous savings potential in technology (up to 50%) and especially in the simpler and safer construction design (up to 90%) when compared with other systems.

The system

The HydroGuard® flushing and impounding protection can swivel in or out from above into the canal section at any position required. The special design of the impound plate is suitable for both underflow and flow-over.
Activation is carried out by a local PLC control with integrated measuring and regulating technology based on a program of operation.
Ascertaining respective headwater and backwater levels is standard.
Additional data such as water quantity and quality can be included for comprehensive programming and management. Any connection required to a master or central control system is standard.

Patent pending
The HydroGuard impound plate is swivelmounted and can be held in any position.
