Paper format. National Examination, May 2018 — 16-Civ-B5
Water Supply and Wastewater Engineering. Three hours, closed book, one two-sided aid
sheet and an approved Casio or Sharp calculator permitted. Question 1 is
compulsory and candidates attempt any three of Questions 2–5; every question
carries 25 marks. Marks are shown at the end of each question and the paper explicitly
invites candidates to state any assumptions they make. All five questions are
worked below, because the set is a study resource rather than a three-hour sitting.
