Average Cost of Installing A Water Main
One of the first things you should realize before planning to install a water main is that costs can vary significantly from project to project. The type of pipes used and the distance between the water supply and the home plays a large role in the final expenses, and you should focus on your specific project when planning for the budget. However, you may find it helpful to know that, on average, the cost of installing a water main runs between $2,061 and $2,833.
Determining the Appropriate Pipe Material
As mentioned above, the type of pipe used to convey water between the water supply and the home is something important to consider. If you live in a warmer climate where freezing temperatures are less of a concern, for example, then PVC pipes are the most affordable option. Copper is another popular material, but it can't be used for piping in places where certain elements in the soil cause corrosion.
Applying for Permits Before You Begin
Before you begin any step of the installation process, you or your professional team will need to apply for a water main permit. Generally, these are based on the length of the water main, which means that the further you are from the water supply, the more expensive the permit will be. The smallest water mains, measuring 200 feet, may only cost $150 for the permit, but longer main permits can cost as much as $1,400 in some locations.
Additional factors to keep in mind might include obstacles between the water supply and your home and whether there is any concrete or pavement in the way.
