This post is a collection of some Spanish wastewater-related vocabulary (I've previously done something similar in Arabic).

I've been trying to increase my knowledge of Spanish. This has been partly inspired by travelling and partly by my company having some projects in Latin America. I've been using the app Duolingo on my phone, but that doesn't cover the kind of technical vocabulary that is relevant to the latter reason.

One of my co-workers loaned me this glossary; I've selected the words/phrases listed below from it to study.

* There are many different kinds of pumps and valves, so I've included the pages with those terms for reference rather than listing them all.

"Bombas":

"Válvulas":

The above list has 80 terms in total. There were none starting with Q or X that were relevant, which reflects letter frequencies. I should have noted whether each term in Spanish was masculine or feminine, and whether they were nouns, verbs, etc. (most are nouns).

The glossary was published in 1998, so there are not many terms related to MBR (biorreactor de membrana) technology. I've also added a few extra terms (using Google Translate) that also weren't entries in the glossary:
