Water Distribution Competition
(Hosted at Port Rex)
Rudi Scheepers, from Arcus Gibb (a local Civil Engineering Consulting Company), presented a Power Point Presentation of the critical situation that South Africa is facing daily due to our shortage of running water. Whole towns have been without water for quite some time and only up until a few weeks ago have they got running water in their taps again. Mr.Scheepers emphasized the need for the harvesting of water. By this, he meant that Jo-Jo tanks or similar containers need to be installed to catch excess rain water and store it and use it in time for various household needs.
And thus we come to the Water Distribution Competition to fix such problems.
Teams from participating schools are given 3 random points on a board with a horizontal grid or network of 4 points x 4 points. These 16 points could represent a block of flats , a small complex of town houses or an industrial area. All the residents of the preferred area need to receive the same amount of water at any given time.
Participating teams are supplied with 12 x 6mm plastic pipes, 12 x 3mm plastic pipes, a container full of all kinds of connectors and reducers as well as a bucket that contains 3 litres of water hanging from a stand much like the one used to hold a drip in hospital upright. After making sure that all air bubbles are eliminated, the contestants need to distribute 1 litre of water to each of the 3 buckets of water on the grid in one hour. Three attempt are allowed in one hour and should a team be fast enough to complete the third run, they are awarded 50 bonus points. Some of the buckets may contain more than 1 litre of water or less when their 3 litres of water run out. The contents of the 3 buckets are then measured and any bucket that contains less or more than 1 litre will incurr penalty points -1 point per millimeter irrespective of whether the buckets contain less or more than 1 litre.
These are the rules and format of the Water Distribution Competition.
