After days of rain­fall in the Nong Yai dis­trict of the Thai province of Chon­buri, the new­ly installed HydroSlide V‑type flow reg­u­la­tor was able to prove its reliability.

The ori­fice plate of the VN-type dis­charge con­troller, which has been installed in a new stormwa­ter over­flow basin, is moved ver­ti­cal­ly in front of the pas­sage open­ing by means of a float mech­a­nism. In this way, it reg­u­lates the flow auto­mat­i­cal­ly and with­out exter­nal ener­gy to the set max­i­mum flow rate.
