Unfortunately, the plan cannot be approved until the following items are corrected. The specific section in Title 5: 310 CMR 15.000, or North Andover regulation that is not met by this design follows each item where applicable. 1. The septic tank and pump chamber shall each have a note specifying that each riser/manhole be childproof(310 CMR 15.221, 15.228(2) and 15.231(5)). 2. The depth of the leach trenches in the site plan and the typical leach trench end section conflict with each other as they call for a depth of V and 16", respectively. The depth of the trench must be changed as needed to be consistent throughout the design plan. 3. Depict inlet tee inside the distribution box. Please feel free to contact the office or Mill River Consulting at 978-282-0014 with any questions you may have. We look forward to working with you to obtain a wastewater treatment and dispersal system which will be in compliance with all regulations and assure protection of public health and the environment of North Andover.
