Approved Title 5 innovative/alternative technologies

MassDEP must approve alternative septic systems for use in Massachusetts.

Table of Contents

Overview

Under the Title 5 Regulations (310 CMR 15.000), MassDEP must approve an innovative/alternative septic-system technology before it can be used in Massachusetts. There are 4 categories of approval:

  • General Use systems will provide a level of environmental protection at least equivalent to that of a conventional on-site system designed in accordance with Title 5.
  • Provisional Use approval is intended for evaluation of alternative systems that appear technically capable of providing levels of protection at least equivalent to those of a standard on-site disposal system.
  • Piloting is intended to provide field-testing and technical demonstration to determine if the technology can or cannot function effectively.
  • Remedial Use systems improve existing conditions at a particular facility or facilities served by a failed, failing, or nonconforming system.

Please note that MassDEP approval does not constitute an endorsement of any specific technology.

In each case, the system owner must follow the inspection and testing schedule required by the approval. Contact the manufacturers listed for schematics of these technologies. 

In addition to the approval categories listed above, Title 5 also allows the use of effluent tee filters at the outlet of the septic tank in lieu of an outlet tee.

In 310 CMR 15.000, Title 5, Best Available Nitrogen Reducing Technology is defined as having the capability to achieve effluent TN levels of 10 mg/L or better. There are currently no technologies with General Use approval that achieve that performance standard. Currently, all of the denitrifying technologies with General Use approval have a TN approval limit of 19 mg/L. Per Section 15.002 of Title 5, there are two alternative routes to determine BANRT in this situation:

  1. "An alternative system with the lowest Total Nitrogen effluent performance value certified by the Department for general use when the Disposal System Construction Permit application is filed and has been approved for the type and design flow of the facility where it is to be used; or" 
  2. "An alternative system(s) granted provisional approval by the Department pursuant to 310 CMR 15.286 or an alternative system(s) approved by the Department for piloting pursuant to 310 CMR 15.285; provided that for an alternative system(s) granted provisional approval or an alternative system(s) approved for piloting such system(s) is approved for the type and design flow of the facility and has a Total Nitrogen performance value less than or equal to 10 mg/L; or, if no system(s) with a Total Nitrogen performance value less than or equal to 10 mg/L has received general use approval, then a system(s) with a Total Nitrogen effluent performance value less than or equal to the lowest alternative system(s) certified by the Department for general use pursuant to 310 CMR 15.288 when the Disposal System Construction Permit application is filed."

Per 310 CMR 15.215(2)(g), The Department may allow the use of technologies that do not meet the Best Available Nitrogen Reducing Technology definition in the event of significant supply or market limitations.

All Technologies Approved for Use

Approved for General Use

Through broad field use in Massachusetts or other states, alternative systems with Certification for General Use will provide a level of environmental protection at least equivalent to that of a conventional on-site system designed in accordance with 310 CMR 15.000 through 15.296. These systems can be used anywhere a conventional Title 5 system can be installed. The system owner is required to have inspection and testing performed as required by the approval on a regular schedule. All alternatives in other categories of approval could eventually be certified for General Use. Contact the manufacturer for schematics of these I/A technologies.

Approved for Provisional Use

This category is intended to evaluate, under actual field conditions, alternative systems that appear technically capable of providing levels of protection at least equivalent to those of a standard on-site disposal system. These systems are generally approved for nitrogen reduction but can be approved to evaluate reduction of other parameters. The system owner is required to have inspection and testing performed as required by the approval on a regular schedule throughout the Provisional Use period. Each Provisional Use technology shall install at least 50 systems pursuant to its approval. These systems can be installed for new construction or on remedial sites to replace a failed system. Contact the manufacturer for schematics of these I/A technologies.

Approved for Piloting Use

Piloting is intended to provide field-testing and a technical demonstration to determine if a particular alternative technology can or cannot function effectively. Technology is only approved when the Department has determined, based on relevant technical data, that the proposed alternative is likely to be capable of a level of environmental protection at least equivalent to that of a system designed in accordance with 310 CMR 15.100 through 15.293. These systems are generally approved for nitrogen reduction but can be approved to evaluate reduction of other parameters. Up to 15 systems can be installed and tested for a minimum of 18 months. The system owner is required to have inspection and testing performed as required by the approval on a regular schedule throughout the Piloting period. Contact the manufacturer for schematics of these I/A technologies.

Approved for Remedial Use 

Remedial Use-approved alternative technologies are used to improve existing conditions at a particular facility or facilities served by a failed, failing or nonconforming system. The alternative system shall have evidence of effective past performance for at least one year of general usage in another state and will provide a level of environmental protection at least of a system designed in accordance with 310 CMR 15.100 through 15.293. The alternative can be used where there is no increase in design flow at the facility. The system owner is required to have inspection and testing performed as required by the approval on a regular schedule. These systems can only be installed on remedial sites to replace a failed system. Contact the manufacturer for schematics of these I/A technologies.
