Explore how utility locating for ADUs extends beyond gas and electric, ensuring seamless sewer connections as well. Uncover essential insights for successful installations.

Accessory Dwelling Units (ADUs) are all the rage these days. You’ve probably seen those cute little houses popping up in people’s backyards, right? People are realizing how great it is to have extra space at home, whether it’s for family, making some extra cash with renters, or just having a sweet home office. And you’re a seasoned professional contractor ready to build a gorgeous, functional ADU for your client. You have everything you need: the blueprints, the permits and the crew with that can-do attitude.

But hold up before you start digging! You know that you’ve got to figure out where all the utilities, sewer line and any other hidden underground gremlins are buried. And when it comes to connecting your new ADU to this subterranean network maze, things can get tricky, fast.

That’s where the magic of utility locating comes in.

Utility Locating Beyond Gas and Electric: Sewer Line Connections

Now, since you’ve done a bunch of building projects, you are keenly aware that using a professional utility locating service is a necessity for a successful build. But, for a successful outcome of your ADU project, there’s a lot more to it than just marking gas and electric lines. You must have a utility locating pro that also has an in-depth knowledge of locating and inspecting sewer line connections! It’s like the difference between dancing in a bright ballroom and dancing in a dark minefield with a blindfold on.

These skilled technicians are detectives with cool gadgets, sniffing out the hidden stuff to make sure your ADU project goes smoothly and safely. We’ll get more into how they pull this off in a bit.

Blueprint Blind Spots: Why You Need More Than Just a Pretty Picture

So, you might be thinking, “I have a good set of blueprints that shows everything. I’m good.” Think again. While they might show you the general location of where the sewer line and utilities are, it’s really kind of like a blurry photo – lacking details. For instance, they don’t show you the crucial details like:

Camera & Sonde
  • Exact position of the sewer line. Imagine digging a trench for your sewer line and not finding it where the blueprints say it is and you just keep digging and digging, wasting time, money and energy.
  • Material and size of the sewer line. Those blueprints might not tell you what the sewer line is made of – PVC? Clay? Cast iron? – or if it changes from one material to another and, if so, where. This is all is crucial information you need to tie into the line.
  • Depth of the sewer line. They don’t show you how deep the sewer line is or where it’s deep enough to get the right gradient (slope) to connect the ADU to the line. Have you ever had plans that show the connection point is only 20 feet away from the ADU, only to find out that spot is not deep enough for the right flow and had to trench another 50 feet to get to the right depth? Whoa!

So, if you’re thinking about skipping utility locating and relying only on the blueprints, buckle up, you might be in for a bumpy ride. Those missing details can make or break your ADU project.

Utility Locating Can Save Your ADU from Plumbing Hell

So, what’s a savvy contractor to do? Some might wonder why they should use a utility locator to find a sewer line. Why not just use a plumber? Well, not all plumbers have the right equipment to locate a sewer line. But if they do, that’s all they’ll find for you. A utility locator will not only have the proper equipment to locate and inspect your sewer line, but they’ll also find any other utilities in your path.

The Dynamic Duo: Sewer Camera + Sonde

Among the arsenal of locating equipment a private utility locator has, the real magic is in the dynamic duo of a sewer camera and a sonde:

Camera & Sonde
  • The All-Seeing Eye. A sewer camera is like a waterproof GoPro that that acts as your real-time underground explorer, providing a live, visual inspection of the sewer line’s internal condition. Think of it as a colonoscopy for your pipes – not pretty, but essential for detecting cracks, blockages, and other potential problems.
  • The Navigator. A sonde is a gadget that is the camera’s trusty sidekick. It is connected to the camera and sends out a signal that shows you where and how deep the sewer line is, also in real time.

Now, imagine combining the visual info from the camera with the positional accuracy of the sonde, all documented for your reference. That’s the true power of a skilled utility locator, ensuring you not only find the sewer line, but also understand its condition so you can connect to it the right way.
