There are a lot of confusing terms associated with the Uplands sewage separation project, but two of the most common acronyms that were tossed around were MSR and INI. In the hopes of lifting some of that confusion, a quick debrief:

INI or Inflow and infiltration. Essentially the water that leaks into the system from the cracks in the pipes, bad joints, manhole covers, etc. CRD has a good page on INI.

MSR or Municipal Sewage Regulation: The provincial law that governs sewage systems, both sanitary and storm. This is the law that is forcing Oak Bay to twin the Uplands sewer. The full regulations and FAQ are available online.
