What is the difference between an approval and a permit?
An approval allows a new water or wastewater treatment facility, reclaimed water facility, or reuse water system to be constructed, or an existing facility or system to be modified. A permit allows a facility or system to be operated.

For example, when the engineering plan review process for a new water treatment plant project is completed an Approval to Construct certificate is issued to allow the construction of the plant to commence. After construction of the water treatment plant is completed an Approval of Construction certificate is issued and the treatment plant is allowed to be operated as stipulated by the conditions of its permit.
