Phase II routine inspections are due by June 7, 2018.

On-Lot Sewage Management Program (SMP) Background

At their December 2, 2013 meeting, the Westtown Board of Supervisors approved Ordinance 2013-3, establishing the On-Lot Sewage Management Program (SMP), which requires that all on-lot sewage systems be properly maintained. This program is mandated by the Department of Environmental Protection (DEP) and is intended to help avoid the problems such as environmental health hazards and contamination of our shared groundwater resources, that can result from poorly maintained and malfunctioning sewage systems.  The ordinance can be viewed here: 2013-3 On-Lot Sewage Management Ordinance.

As set forth in Resolution 2013-16 (Resolution 2013-16 OLM Phasing schedule) adopted by the Board of Supervisors on December 1, 2013, the SMP was implemented in an initial cycle of four 9-month phases over a period of 3 years.  Property owners were required to have a comprehensive initial sewage system inspection completed within the schedule for the phase assigned to each property.  The initial cycle of the program ended December 7, 2016, and the results of the first cycle of the SMP were reported to the DEP.  The phasing map can be viewed here: SMP Phasing Map.

On-Lot Sewage Management Program (SMP) Guidance Booklet

All property owners with on-lot sewage systems should read the On-lot Sewage Management Guidance Booklet. This guide explains the background of the program and includes detailed information about on-lot sewage systems, system maintenance, and the specific program requirements. Please read the guidance booklet thoroughly before contacting the Township with any questions.

Routine Sewage System Inspections

The initial cycle (Cycle 1) of on-lot sewage system inspections ended December 7, 2016.  Thereafter, the On-Lot Sewage Management Program (SMP) requires that every system undergo a routine inspection in successive three-year cycles using the SMP Routine Inspection Report.  This means that each system must have a less comprehensive inspection completed once every three years according to the phasing schedule below.

Phase Start End
1 December 8, 2016 September 7, 2017
2 September 8, 2017 June 7, 2018

A map showing the inspection phases can be found here SMP Phasing Map.

Cycle 2 ends December 7, 2019, cycle 3 will end December 7, 2022, with successive cycles every three years thereafter.  The SMP Routine Inspection Report must be completed by a contractor (inspector) certified by the Pennsylvania Septage Management Association (PSMA) hired by the property owner.  This report is to be completed, signed, and submitted to the Township within thirty (30) days of your inspection.  For a list of PSMA certified inspectors, click here:

Routine Pumping

In addition to submitting the SMP Routine Inspection Report once every three years, the SMP requires that each on-lot sewage system be pumped out at least once during the 3-year cycle.  When the system is pumped, the inspector will be able to observe and record the information required on the SMP Routine Inspection ReportIt is highly recommended that system pumping be done at the same time as the routine system inspection.  If pumping is done at the same time as the inspection, a receipt from your pumper should be attached to the SMP Routine Inspection Report.  If pumping is done at another time, then you must submit a copy of the pumping receipt to the Township within 30 days of pumping, but no later than December 7th, 2019.

Note that pumping more frequently than once every three years may be recommended by your PSMA certified inspector to maintain your on-lot sewage system in good working order.  However, for the purpose of the township’s reporting requirements, evidence of only one pump out in each three-year cycle is required, regardless if your system is pumped more frequently.
