Sewer mains are extremely important and require a lot of coordination with your local city or town. The cost to install a sewer line may or may not fall directly on you, but regardless it's good to be informed about the different factors that can impact installation cost. It's crucial to use a professional if your city isn't doing the installation. A licensed professional can help walk you through the process and explain the sewer pipe installation cost for your municipality and home. Here are some factors that might come into play with the cost to install a sewer line.

Housing type

The type of home you live in–stand alone home, townhouse, or part of a housing tract–can affect the cost to install a sewer main line. Some stand alone houses may be responsible for the cost to install a sewer line. In other types of homes, it can be part of city services or a HOA's responsibility, which would be part of a fee. It's important to look into how your city handles sewer issues, and how your neighborhood fits into that plan.

Red tape

Anything sewer-related requires city permits and regulations. These types of permits will add to sewer main pipe installation. If your city isn't in control of your installation, then the professional you work with will need to ensure that everything is covered in this regard. Make sure to figure out who will need to procure the proper permits when talking to your professional before beginning the project.

Distance to connector line

The distance between your home and the connector line will impact the cost to install a main sewer line. The further away it is, the more pipe that will need to be installed, which will raise both materials and labor costs.

Obstacles

Anything that might get in the way of digging will increase installation cost. This means any landscaping or trees will need to be removed before construction can start. Any concrete will also need to be removed. The costs to replace and fix these areas after installation will be additional costs to you to consider.

Existing pipe

If you're replacing an old sewer line, then installation can be more complicated. The existing sewer line might be below your gas line, which would increase sewer pipe installation cost. Digging out old pipe and replacing it can increase the cost to install a sewer line. Another option is the slip lining process, which inserts a smaller pipe within an existing pipe. This is useful if a full excavation becomes impossible due to what's built on top of the existing pipe, or if there are other existing utility lines. This will also raise the cost to install a sewer line.

HOW LONG WAS THE PIPE, LINEAR DISTANCE, AND DIAMETER OF LINER?

That sounds closer to what the Waste Management people told us in a town hall. I was wondering if this was just the connection charge and not the pipe to the road like I thought it was. We were told it was $1500 to just tap in plus we had to run the pipe from the house to the tap in point. We have to hook up a 164 year old house that just has various pipes going to the river. We might have to plumb the whole house again to accommodate this which is going to be even more costly but it is the responsible thing to do so we aren't dumping raw sewage into the river.

Easy. Lets see how it works out
