I am not native english speaker and I'm currently writing my PhD thesis on economics. The research question is whether water suppliers are minimizing their costs. However, my problem is that I seem to repeat the phrase "water suppliers" too much, and I'd like to introduce some variation.
So far, I've been using these names:
- Water utility companies
- Water suppliers
- Water utilities
- Water companies
I'm not entirely sure that all of them are correct. What other names would you recommmend me to use?
Also, I often use the words "firm", "enterprises", and "company" once it is clear they're water suppliers. Are these terms correct in the context of water suppliers? Take this phrase, for instance: "the prices faced by this firm are smaller than the rest of the companies." It feels a bit awkward for me to say that phrase when talking about water suppliers.
I am still on an early stage of the writing, so I can change the style completely if needed. Thanks in advance for your responses.
