If the water main layer is a line feature class and you have access to ArcGIS Desktop with an Advanced License level, one workflow would be to first run Feature Vertices To Points with the Mid Option to establish a point feature class of the midpoints, then run Split Line at Point.

Feature Vertices To Points—Data Management toolbox | ArcGIS Desktop

Split Line at Point—Help | ArcGIS for Desktop

Info on splitting line features:

It is good answer if he has advanced license.

Feature Vertices To Points
Available with Advanced license.

also split line at point available with Advanced license.

Also, I have access to Basic version of ArcGIS but can get access to Standard or advanced if needed

How many pipe segments does you have in the layer?

Because of having basic license. I have a long solution.

Frist . create 6 fields

2 for start line X and Y coordinates

2 for mid point line X and Y coordinates

2 for end line X and Y coordinates

Second Calculate geometry , for each field.

Third use XY To Line—Help | ArcGIS Desktop twice.

-->one time, make start X and Y in the tool for start line coordinates fields, and make end X and Y in the tool for mid line coordinates fields.

--> second time, make start X and Y in the tool for mid line coordinates fields, and make end X and Y in the tool for end line coordinates fields.

Finally use Append—Help | ArcGIS Desktop tool to make the two output in one layer, or copy and paste in edit session.

Note.

except from this curve line and circle lines. because mid point will not be intersect the line

use split button in Edit toolbar.

Does it work?

The advanced GIS workflow worked for me and took about 10 mins. I didn't try the basic method.
