In the past two issues, we have reviewed definitions of sewage tanks and the design considerations for septic tanks. This month we begin a two-part series on the steps to follow for a good tank installation.
Any installation procedure should start with safety requirements. All excavations should comply with OSHA standards and must be done so as to prevent sidewall collapse. This means keeping the spoil pile at least two feet back from the edge of the excavation.
Proper shoring or excavation boxes should be used where necessary, or the sidewalls must be excavated back at the proper angle for the soil
Placing the Tank
Proper installation procedures can ensure that the septic tank and related piping remain intact and provide long, reliable service
