The catchment area of the surface that directly receives the rainfall. This can be an open ground, courtyard or terrace. The water received is then transported from the catchment area though water pipes or to the storage area. In the pipes, the rainwater is passed through the first flush, as the water may contain contaminants from the atmosphere and the catchment roof. Subsequently, it is to remove color, turbidity and bioforms which may be found. Filters can consist of a charcoal filter, sand/gravel filter, PVC pipe filter or a sponge filter or a of these.

Correct answer: storage
Explanation: The speaker says "system of collection and storage". The word comes after "and", so you need a word for a thing used to keep water.
Meaning: "storage" means a place or container to keep water.
Wrong options:
- storige: It has "i" where the word has "a". Write "storage". Only the exact spelling gets the mark.
- store: "store" is a close word, but it ends in "e". The speaker says "storage", which ends in "age".
Correct answer: comprises
Explanation: You hear "The catchment area comprises of". You need a word that means includes, and it has s at the end.
Meaning: "comprises" means includes or is made up of.
Wrong options:
- comprizes: It has "z" where the word has "s". The right spelling is "comprises". Every letter must be correct to get the mark.
- comprise: "comprise" has no "s" at the end. The speaker says "comprises", so write the "s".
Correct answer: drains
Explanation: Listen for "water pipes or drains to". The word is a thing that takes water away, so watch the ai spelling.
Meaning: "drains" means pipes or channels that take water away.
Wrong options:
- dranes: It leaves out the "i" and it adds an extra "e". The right spelling is "drains". Every letter must be correct to get the mark.
Correct answer: filtered
Explanation: On the recording you hear "it is filtered to remove". The sentence already happened to the water, so the word ends in ed.
Meaning: "filtered" means cleaned by passing through a filter.
Wrong options:
- filterd: It leaves out the "e". Check the letters: "filtered". A small spelling mistake loses the mark.
- filter: "filter" is missing the ending. The speaker says "filtered", with "ed" at the end.
Correct answer: combination
Explanation: Listen again to "a sponge filter or a combination". The word is for mixing items, so do not forget the tion ending.
Meaning: "combination" means a mix of different filters.
Wrong options:
- combiation: It leaves out the "n". Check the letters: "combination". A small spelling mistake loses the mark.
