SURCHARGING
Surcharge calculations are now usually required fot networks in two forms.
1 - Surcharge to free flowing outfall.
2 - Surcharge to a level above outfall soffit ( usually 1m )
MASTERDRAIN has the capability, not only to perform these calculations quickly and accurately without pages of unwanted data found in other design packages, but also to provide indivdual hydrographs for manholes on the network , enabling the designer to monitor the performance of each manhole individually and to produce additional textual or graphical output to demonstrate the performance of his network.
