Abstract

The estimation of wastewater flows is a fundamental requirement in the
design of successful wastewater systems. The sizes and capacities of all
major components are dependant on the predicted amount of wastewater
flow that will originate from the contributory areas within the proposed
catchment.
The reliability of flow estimates depends on the accuracy of many
assumptions. These include the future water demand and resultant
wastewater production, population growth or decline, population density
variations, socioeconomic changes, land use changes, and the maintenance
of the wastewater system infrastructure. It is essential that the wastewater
system has adequate capacity for peak wet weather flow, but can also
function satisfactorily at minimum flows without operational problems
(Great Lakes Upper Mississippi River Board of State Sanitary Engineers
1978, p. 12).
The Colombo formulae (1) and (2), is a theoretically derived formula used
to predict peak wet weather flow in separate wastewater systems. This
formula has been by Melbourne Metropolitan Board of Works and Sydney
Metropolitan Board of Works since the late 1960s (Coulsen, J 2004, pers.
comm., 15 June), and is currently used at Gippsland Water. -- Complete abstract not reproduced here: see main document for complete abstract.
