RE: Subsurface Sewage Disposal System Plan for 239 Granville Lane,North Andover, MA,
map 106 Parcel 66
Dear Mr. and Mrs, Gagnon,
The North Andover Board of Health has completed the review of the septic system design plans,
for the above referenced property. These plans dated May 29, 2009, final revision date of July 1,
2009, have been approved for a five (5) bedroom, maximum eleven-room home.
In accordance with local subsurface disposal regulations "Acceptable plans and any variances
shall expire two years from the date approved unless construction on the lot has begun". During
this time a licensed septic system installer must obtain a permit and complete this work, and a
Certificate of Compliance must be endorsed by the installer, designer and the Town of North
Andover.
Regulation requires that waste exit the structure through a single building sewer and local rules
require that the building sewers be in a single straight line from building to the tank. Due to
special circumstances identified by the designer the following was approved.
1) 2 building sewers are allowed
2) Bends are allowed where necessary and a single clean out is permissible.
These circumstances included the finished interior of the basement and the location and the
elevation of the gray water pipe. Each precluded full compliance to the regulation as they would
cause extreme hardship to the owner of the property if enforced.
This approval is subject to the following conditions:
1, A licensed electrician must pull an electrical permit and submit proof to the Health
Office prior to disposal works construction permit issuance.
2. As the building sewer is proposed to be moved, a licensed plumber must pull a permit
and submit proof to the Health Office prior to disposal works construction permit
issuance.
3. If site conditions are found in the field to be different from those indicated on the
design plan and/or soil evaluation,the originally issued Disposal System Construction

Phone 978.688.9540 Fax 978.688.8476 Web www.townofnorthan(lover.com
Permit is void, installation shall stop, and the applicant shall reapply for a new
Disposal Systems Construction Permit(3 10 CMR 15.020(1)).
4. It is the responsibility of the applicant and/or the applicant's septic system designer,
septic system installer or other representative to ensure that all other state and
municipal requirements are met. These may include review by the Conservation
Commission, Zoning Board, Planning Board, Building Inspector, Plumbing Inspector
and/or Electrical Inspector. The issuance of a Disposal System Construction Permit
shall not construe and/or imply compliance with any of the aforementioned
requirements.
Your effort to provide a properly functioning septic system for your dwelling is greatly
appreciated. The Health Department may be reached at 978-688-9540 with any questions you
may have.
