DRP flow regulator | Rainwater Flow Regulators
Due to the irregular nature of rainfall and the associated flow changes, rainwater flow regulators called DRP manufactured by NavoTech are mainly used in the construction of rainwater drainage systems with water retention and storage systems, where the sewage system and installed WOD-KAN devices may be exposed to periodic hydraulic overloads, which may cause their improper operation or damage and thus environmental damage.
DRP flow regulators can be installed in ROK retention tanks, NT-BAS drainage chamber systems, and overflow systems.
NavoTech's proprietary solutions in DRP regulators ensure flow equalization and positively impact the operation of existing stormwater drainage systems. The DRP rainwater flow regulator can be installed directly in retention tanks or in an intermediate well at the reservoir outlet. Thanks to the use of these materials in the production of DRP regulators, they are resistant to aggressive environmental conditions, do not corrode, and do not require additional protective coatings or any maintenance.

NavoTech offers rainwater flow regulators with nominal flow rates ranging from 0,5 [l/s] to 500 [l/s]. For larger flow rates, regulators are available upon request. They are manufactured from high-density polyethylene (PE-HD) or acid-resistant stainless steel.
The following elements of rainwater management produced by NavoTech are dedicated to work with DRP rainwater flow regulators:
- retention reservoirs YEAR,
- water pumping stations NAVO,
- drainage chambers NT-BAS,
- check valves ProFlex i return flaps KP.
DRP rainwater flow regulators by NAVOTECH are products made entirely of PE. Their main advantage is the material that is neutral to the environment.
The capacity range of devices from 0,5 [l/s] to 250 [l/s] allows to meet the needs of the most demanding investors and users.
The rainwater flow regulator can be installed in wells, at the outlets of retention reservoirs and other unusual sewage systems.
Thanks to its design, the device does not require any internal maintenance, and there is no need to disassemble the flow regulator for service.
Devices selected individually
There are various mounting options for DRP regulators. You can screw them:
- to the bottom of the tank,
- to the tank wall,
- flange stub,
- bare spigot.
Rainwater flow regulators can also be extrusion-welded. We consider every installation option, and our engineers can custom-design the device to meet the investor's requirements.
