The Details

What you need

The purpose of these approvals, except tight tank approval, is to ensure that alternative Title 5 systems, which have substitute or alternative components for one or more elements of a conventional septic system, can provide the same or a higher degree of environmental and public health protection as a conventional system.

  • WP 57 establishes an approval process for MassDEP review of proposed Recirculating Sand Filter installation where nitrogen reduction is required (see 310 CMR 15.214) for new construction, or proposed installations of RSFs for remedial use to serve facilities with design flows of 2,000 gallons per day or greater.
  • WP 64b establishes an approval process for MassDEP review of alternative systems proposed for piloting on a specific site. Piloting is intended to demonstrate that the proposed technology is likely to provide a level of environmental protection at least equal to that of a system designed and built in accordance with Title 5.
  • WP 64c establishes an approval process for MassDEP review of alternative systems proposed for remedial use on a specific site. A Remedial Use approval is intended to demonstrate that the alternative system is likely to improve conditions at an existing facility served by a failed, failing or nonconforming system.

You must apply for these approvals if one of the following applies to your project:

  • WP 57: Any individual, business or organization desiring to install a recirculating sand filter, in accordance with the Department’s Approval for Remedial Use for RSFs (310 CMR 15.202, 310 CMR 15.214).
  • WP 64b: Any individual, business or organization desiring to install an alternative system for piloting (310 CMR 15.003 and 310 CMR 15.285).
  • WP 64c: Any individual, business or organization desiring to install an alternative system for Remedial Use that is required to obtain prior MassDEP approval (310 CMR 15.003 and 310 CMR 15.284).
