Do You Need a Waterline Replacement?
Your main waterline is built to last decades, but corrosion, soil movement, and tree root intrusion can cause it to deteriorate faster. Here are some common signs your waterline may need replacement:
- Sudden drop in water pressure
- Unexplained water bills that keep rising
- Discolored or rusty water
- Wet spots or puddles in your yard
- Frequent leaks or pipe repairs
- Visible corrosion on exposed pipes
If you’re experiencing any of these issues, it’s time to have your plumbing system professionally inspected.
Main Waterline Replacement Process

Traditional vs. Trenchless Waterline Replacement
When it comes to replacing a damaged or aging waterline, you’ll typically have two main options: traditional or trenchless replacement.
- Traditional methods involve excavating a trench along the entire length of the pipe, which can disrupt landscaping, driveways, and walkways. While effective, this approach often results in longer project times and higher restoration costs.
- Trenchless waterline replacement, on the other hand, uses advanced techniques like pipe bursting or pipe lining to replace or reinforce the pipe without digging up your yard. This method is faster, less invasive, and often more cost-effective in the long run. It’s ideal for properties with established landscaping or hardscape features.
At Ongaro & Sons, we evaluate your property to determine the best method—ensuring minimal disruption and long-lasting results. Whether traditional or trenchless, our goal is to restore your water supply with precision and care.
Trenchless Pipe Bursting Process
The trenchless pipe busting process begins with a camera inspection so we can properly assess your current waterline. Then, we will dig two small holes at both ends of the pipe’s location so we can feed a steel cable underground through your waterline.
Our team of experienced professionals will use the appropriate tools and equipment to simultaneously break apart the old pipes and replace them with new piping.
