Septage Discharge
Septic System Management for Homeowners

If you are not connected to the City sanitary sewer collection, your home is probably connected to a septic system. A septic system is a decentralized wastewater treatment facility that biologically treats the wastewater from the home connected to it. It is important to maintain septic systems to avoid blockages, overflowing, and other possible damages to the leach field. Watch New Hampshire Department of Environmental Services' video about Septic System Management for Homeowners for more information.


Septage Discharge for Haulers

Domestic septage can be discharged at the Hall Street Wastewater Treatment Plant at 125 Hall Street. Only domestic septage may be discharged at the facility.

What Is Domestic Septage?
Domestic septage is either liquid or solid material removed from a septic tank, cesspool, portable toilet, Type III Marine Sanitation Device, or a similar treatment that receives only domestic sewage. Domestic septage does not include liquid or solid material received from commercial or industrial wastewater. It also does not include grease removed from a grease trap.

Non-domestic septage from Bow, Boscawen, and Concord may be accepted if prior approval has been authorized by our Laboratory Supervisor. It is required to request approval in advance. A list of previously authorized non-domestic sources is on file for reference.

Permit Requirement
All haulers must obtain a Septage Hauler Discharge Permit prior to discharging septage at the Hall Street Wastewater Treatment Plant. Permits are issued to haulers that meet the following requirements:

  1. Completed Septage Hauler Discharge Permit Application Form
  2. Submitted $200 permit application fee
  3. Provided an insurance certificate with the City of Concord as an additional insured
  4. Provided a payment bond (amount specified by the City of Concord). Permitted haulers will have a required payment higher of either:
    • $5,000
    • or, the amount of the two highest consecutive months of service during the 12 month period (ending April 30 of the current fiscal year) rounded up to the next $1,000 increment. Newly permitted haulers will have an estimated annual septage volume calculated at the current Outside-District rate. 

Haulers must have a satisfactory record of compliance with all conditions and requirements to receive a permit renewal. Haulers are invoiced monthly for the previous month's disposal services. The invoice is due within 30 days of the invoice date. Any account in arrears will result in immediate revocation of the haulers' disposal privileges. 

Violation of any of these permit conditions can result in the suspension or revocation of the permittee's disposal privileges.     

Manifests
Haulers must complete and return a City of Concord Septage Discharge Manifest for each source of septage on a truck load. Manifest forms are available at the Hall Street Wastewater Treatment Plant. 

Prohibited Sources

The following are all sources that are prohibited from septage discharge at the Hall Street Wastewater Treatment Plant:

1. Grease traps

Septage Discharge Fees
Effective 7/1/14, septage discharge fees are assessed for in-district and outside-district sources at a rate per gallon. In-district sources include Concord, Penacook, Boscawen, and Bow. All other communities are considered an outside-district.

  • In-District = $0.075 per gallon
  • Outside-District = $0.085 per gallon

Volumes are determined to the nearest 100 gallon increment based on sight glass readings. The minimum volume for invoicing is 500 gallons.

Receiving Procedures
Septage is only received at the Hall Street Wastewater Treatment Plant at 125 Hall Street. Septage can be received during our regular business hours, excluding City recognized holidays. 

All haulers must check-in at the lobby of the Administration Building. Follow the instructions in the reception lobby to page our staff to accept the load. Our staff will review the Septage Discharge Manifest for all required information. Any missing or incomplete information shall cause the load to be rejected.

Personnel will verify the declared septage volume by sight glass readings. The load will be charged at full tank volume if there is no sight glass available or if it is not readable. Full tank volumes will be determined from a registered tank listing of all City permitted septage haulers. Any adjustments to the original declared volume will be recorded on the Septage Discharge Manifest and verified by the hauler. Refusal to verify the adjustment will ensure refusal for the load. City personnel will sign and date the Septage Discharge Manifest and authorize the discharge.

Septage cannot be discharged without prior official City authorization.
