Paper format. National Examination, May 2017 — 16-Civ-B5 Water Supply and Wastewater Engineering. 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. All five questions are solved below, because the set is a study resource rather than an exam script.
