Are water tank overflow pipes always needed?

Diverting additional downpipes often causes the inflow capacity to exceed a water tank’s overflow capacity during heavy rain.

  • Water tank overflow outlets or pipes are required to be fitted with either mosquito proof mesh or a flap valve. The mesh typically has an open area of about 55% which presents a flow restriction within the overflow pipe.
  • Many water tanks are designed with very high overflow outlets which severely reduce a tank’s mitigation and discharge capacity.
  • Water tank manufacturers rarely if ever provide information about a tank’s overflow capacities.
  • An organic film floats on the tank’s water surface during and after rain. This often gels to the overflow mesh during overflows, causing an increased flow restriction.
  • Overflow pipes are often costly to install.
  • Downpipes diverted along walls are ugly.
BUT height adjusting SUPADIVERTAs to downpipes can eliminate the need for a water tank overflow pipe!
Fit supadiverta so overflow pipe not required on tank

  • A SUPADIVERTA height adjusted on a downpipe with the top of the reservoir wall 2 cm below the bottom of the tank’s overflow outlet will overflow back to the stormwater system when the tank fills.
  • If no other downpipes drain to the water tank’s top meshed inlet, there is no need for a water tank overflow pipe!
  • Deleting or capping a water tank’s overflow outlet increases storage capacity. It also allows the Supadiverta to be fitted higher on the downpipe to generate increased head pressure.
  • If a tank already has an overflow pipe connected and a downpipe diverts to the tanks top meshed inlet, additional downpipes can be diverted to the tank by Supadivertas without affecting the tank’s overflow capacity.
  • Using Supadivertas which divert rainwater to stormwater when the tank is full reduces sediment build up.
  • House brick mortar lines or weatherboards can be used as a ‘line of sight’ when fitting a Supadiverta.
  • Subject to slope, locating a tank away from the house is no longer difficult and expensive.
  • SUPADIVERTA diverts water, not downpipes.
  • Neater and cheaper rainwater harvesting.

Any number of downpipes can be harvested by this method
