The Details

What you need

This permit serves to protect the public's health and welfare through the control of any product or operation that comes into contact with public drinking water. These products and operations must be controlled to prevent contaminants from leaking into the drinking water as well as to ensure that the products and operations work as designed. This permit consists of an approval for the installation of one type of MassDEP approved vending machine or point-of-use (POU) treatment device or point-of-entry (POE) treatment device at 1 to 9 locations on the same distribution system. Legislative authority for this permit is stated in MGL Chapter 111, Section 160A. Regulatory authority for this permit is stated in 310 CMR 22.04 and 310 CMR 22.23 of the Drinking Water Regulations.

Public Water Systems (PWS), facility owners, manufacturers or their designated representatives seeking approval for the installation of one type of vending machine or POU/POE treatment device at 1 to 9 locations on the same distribution system must apply. If 10 or more vending machines or POU/POE devices are to be installed on a distribution system, see application WS 35. POE devises that are installed solely to enhance the aesthetic quality of the drinking water, and meet the minimum requirements detailed in 310 CMR 22.23 (6), are not required to apply for this permit.

In addition to this permit, it may also be necessary to apply for other MassDEP water treatment permits, e.g. WS 21, 22, 23, 24, 25, 28, 29, or 34.
