Project overview
The model shows a building with a sloped roof, gutters feeding a downpipe, a first-flush diverter, a filtration chamber and a percolation pit cut away so the layers of gravel and sand are visible. Water poured onto the roof travels the whole path, so the process is demonstrated rather than described.
The first-flush diverter is the part most school models leave out and the part judges most often ask about. The first few minutes of runoff carry dust and bird droppings off the roof; diverting them protects the stored water. Including it, and being able to say why, immediately distinguishes the project.
It is a strong topic for Surat specifically, where heavy monsoon runoff and groundwater depletion are both visible local issues, so the model connects to something the student and the judges can see around them.
Features
- Complete path from roof to recharge shown in one model
- First-flush diversion included and labelled
- Cut-away filtration chamber with visible media layers
- Water can actually be poured through for a live demonstration
- Printed labels and flow arrows sized to read from a metre away
How it works
- 1Water poured onto the roof runs into the gutters and down the downpipe.
- 2The first portion is diverted into the first-flush chamber and held there.
- 3Once that chamber fills, the remaining flow passes on to the filtration chamber.
- 4It percolates down through gravel, charcoal and sand into the storage tank.
- 5Overflow from the tank is directed into the cut-away recharge pit to show groundwater replenishment.

Questions about this project
Can water actually be poured through it during the exhibition?
Yes — it is built to be demonstrated with water. A collection tray and a jug are worth taking with you so the table stays dry.
How big is the model?
Typically around two feet wide so it fits a standard exhibition table and can be carried. Tell us if your school has set a size limit.
