Serving Southern California since 1978

Our Process

In the entire forty-five years we’ve been in business, Caliagua has worked very hard at one thing; earning the trust of our customers. People say we’ve done a pretty good job of that. We’ll let you be the judge. Take a look at some of the great customers we’ve had the pleasure to partner with over the years. Then take a look at some of the projects we’ve done for them and listen to what some of them have had to say about their experiences with us.

If you have a water treatment or sewage lifting project in or around Orange County, we’d like to add you to our list of customers we’ve been serving well for all these years and by all means feel free to get ahold of us!
