SEPTIC TANK PROFILE SYSTEM REQUIREMENTS AND SPECIFICATIONS 1.General Board of Health approval required before licensed contractor installs system. Obtain Disposal Works Permit. All construction to be in accordance with Title 5 (310 CMR 1500) of the State Environmental Code. Contractor responsible for verifying all dimensions, elevations and conditions. Contact System Designer immediately if discrepancies are found. Alternatives to these specifications should be discussed with the System Designer, Tom Leue, in advance at (800) 285-4533. Property lines are approximate, based on best available information. Any required tree cutting is the responsibility of the Contractor. All wells within 150' of system are shown on the drawing. This septic system is not designed for a garbage grinder in the kitchen, do not connect one to the system or all implied warranties are voided. The contractor selected is required to be certified in this technology before completion of the work. Arrangements for on-site Manufacturer's training can usually be made by arrangements with the company representative Eric Daniels at 800-444-1359. 2.Septic Tank The septic tank for this project is to be Title 5 compliant. Install an outlet filter. Install plastic risers with sealed plastic covers to the final surface over all three access holes. 3.Piping All piping from greywater and blackwater sources to be connected to building sewer in the basement. All piping from the septic tank to the end of the system shall be 4” diameter, SDR-35 or better, except as noted on the drawings. Joints are to be sealed water tight. Place magnetic detectable warning tape pre-printed “Sewer Pipe Below” or similar wording approximately 6” above all new piping and other components installed on this project, other than leaching pads. Two feet out of distribution box pipe to be set dead level. 4.Leaching Facilities All leaching facilities to be of the size, location and brand shown on the drawings. Do not substitue brands without notifying System Designer in advance to see if it affects systems size and design. All fill materials within 12" of the leaching pads to be C-33 certified sand. All other fill within five feet horizontal of the leaching pads to be certified Title 5 sand. Do not excavate outside of the footprint of infiltration pads at the specified depth. Sand characteristics to be documented. Supplier provided Title-5 Sand Analysis shall be less than one year old. Sand suppliers shall ensure that the analysis provided to the Septic Installer is representative by following a written Quality Assurance Plan (QAP) which documents the method(s) used to ensure that a sample report represents the actual material being supplied for use. The System Designer may analyze a sample of the sand on-site to confirm Title 5 specifications. 5.Inspection A minimum of two site inspections by the System Designer are required. Notify System Designer (800-285-4533) at least 24 hours in advance of completion of excavation and before addition of sand to certify site preparation. Notify System Designer at least 24 hours in advance of completion of system construction and prior to backfill for final inspection. The System Designer shall verify the system was installed as designed and authorize the final grading. The Contractor responsible for notifying the local Board of Health for a final inspection. If the System Designer finds the system is not ready for inspection after being called, or if serious deficiencies are discovered, the System Designer must be notified to return to the job site when it is complete. There will be a charge to the Installer of $50 for each return trip, payable directly to the System Designer at the time of the reinspection. Inspection and project closeout forms are usually generated within 24 hours of final inspection by the System Designer, when all other requirements are met. Signed Certificate of Compliance forms and As-built Drawings are sent to the Installer for a signature and date. One set of forms are then returned to the System Designer for final processing. The second set of forms are for the Contractor to keep as his project record. 6.Final Grading At conclusion of work, loam and seed all disturbed areas to perennial grass mixture. Added loam may be required for adequate grass growth. Mulch slopes with hay, burlap or netting to minimize erosion. Surface over leaching facility shall be pitched so as to shed rainwater. Also pitch surface over all tanks to shed rainwater from any exposed covers. Do not allow surface water to puddle over any tank or component. Systems built late in the year, where the grass cover does not have a chance to establish itself, requires the contractor to return after spring thaw and resurface final grades and add grass seed cover as required to equalize and stabilize all disturbed areas.
