MA PHIT- Wastewater Certificate Program, Session 5
Non-Conventional DesignsSituation SolutionSoil too wet for percolation test Sieve test and analysis (upgrades
only) – part of Local Upgrade Approval (LUA)
Upgrade plan does not meet all Title 5 standards
Local Upgrade Approval or Variance*
Project is proposed for over 2,000 gallons per day
Assessment of the soil and ground-water conditions and pressure distribution (PE must be designer)
Domestic garbage grinder Oversize/multi-compartment septic tank and SAS
Upgrade is costly and waivers to standards are being sought
MassDEP Cost Guidance

Non-Conventional SolutionsSituation SolutionCannot meet new construction requirements of Title 5
Variance*
Shared system or components Application and approval processNitrogen concerns Nitrogen loading and aggregationVariation from design flow table Site-specific flow determinationSevere limitations to conventional treatment

Nitrogen Concerns Nitrogen is a pollutant of concern in potable
drinking water, and in coastal embayments which are not well flushed

Design Flow Variations Title 5 has a table for standard facilities but
sometimes this table is not relevant. A site-specific assessment must be made, for design purposes. Examples?
