Welcome to Muninsight, Canada's largest consulting firm dedicated to helping municipalities make strategic decisions using best practices in engineering economics and project management. As an entry-level project engineer, you will be working remotely for the first few months of your job. But you are still an essential part of the Muninsight team. We've been asked by the City of Saskatoon to choose between two new water reclamation options. They've provided us with a fairly complete set of documents, so you don't need to look around for information beyond what's included here. The turn-around for this assignment is fairly tight - 72 hours. But that should be more than enough time for you to complete your calculations and develop some guidance for the City of Saskatoon. Remember, this is your first impression for us, and our first impression for the client, so take the time to edit and fine-tune your language. I've provided you with fairly strict word limits. They don't have a lot of time to read the details, so make sure you explain the necessary information succinctly. That will mean a bit of time editing your text to make sure it is informative and clear. For your first assignment, you've been tasked with comparing the following two processes.
