P NOTICE TO GENERAL CONTRACTORS: Primary and alternate drainfield sites MUST be protected prior to and after system installation to avoid compaction of the natural soil. ALL DRAINFIELD AREAS MUST BE FENCED OFF prior to building site excavation and fencing must remain in place until final site grading. Approval to pour footings will not be granted until the Inspections Department has verified that primary and alternate sites are adequately protected. NO VEHICULAR TRAFFIC OF ANY KIND (cars, trucks, earth moving equipment, etc.) is allowed within 20' of tested drainfield sites either before or after system construction. This applies to the lot you are working on and all adjacent lots. You could be held liable for damaging sites on neighboring lots. VEHICULAR TRAFFIC CAN CAUSE SOIL COMPACTION, RENDERING DRAINFIELD SITES UNUSABLE. Evidence of traffic on drainfield sites may be cause for revocation of building permits. Damaged alternate sites must be replaced before a Certificate of Occupancy will be issued. /1-'151111/144-> A1- d Date Approved Byty or Orono Koch's Soil Testing P.O.

This mound must be pte.ssutized thetepte a pump tank ( 1000 gaffon) and a pump ( 40 g.p.m.- 161 gat/cycee- 4 cycees/day) must be instaeeed. this pump must be abet to ovetcome at feast 11 tit. of head pressure.
