Intro Page

We model a simple steady state catchment and drainage system with stormwater pit and pumps

A catchment is the plan area in which rain falls upon, and flows to drains that serve this catchment.

A particular township may be divided into more than one catchment, and the drains for each catchment may be connected to form a drainage system.

The rainwater collected goes to a stormwater pit and the water is pumped out either to a larger network that eventually discharges into the sea and prevents

localized flooding.

This simulation of the rain water flow is to assist in the design of storm water pit dimensions and water pump sizes
