Paper format. National Examination, December 2017 — 16-Civ-B5 Water Supply and Wastewater Treatment. Three hours; closed book with one aid sheet written on both sides; an approved calculator is permitted. Question 1 is compulsory and the candidate attempts any three of the remaining four questions. Every question carries 25 marks, so the paper is marked out of 100. A partial-flow chart for circular pipes is supplied on page 3 for use in Question 5. All five questions are solved below, because the set is a study resource rather than an exam script.
