Hello All; Residing here on the East Coast of the United States of America, we also get some very high tidal surges and peak flow riparian events. To offset disruption of our POTWs, we have adapted "bypass flow retention systems" which collect the overflow during storm events and restricts this excess fluid volume from the treatment mainstream. Of course, the volume data is different in every location and calculations, projections, and models need to be integrated to compensate for all possible system volume overflow scenarios. The excesses are incorporated back into the mainstream slowly, so as not to interrupt the processes or the regulated flow. This course of action has been proven very successful here at Baltimore over the last several decades ! I hope this may help you in abating a very serious water process problem in New Zealand.
