If I Choose to Tap Into a Water Line, Will I Have the Option of Retaining My Well?

Yes, you are allowed to continue using your well for outdoor, non-domestic water use. However, these sources cannot be cross-connected or used for indoor, domestic use. So, in essence, you must have two separate piping systems: one for inside use, the second for outside. You must also have a backflow device installed to prevent cross-contamination of the public water system.
