Clearances for septic tank, drainfield, soakaway bed, & wells: distances to other site features: this document provides typical septic tank and field clearances. In this article a detailed septic distances table describes distance requirements between septic components (septic tank, leach field, cesspools, drywells) and other site features such as wells, water supply piping, streams, trees, property boundaries, lakes, etc.

However more strict clearances and distances than this are required between various onsite wastewater treatment system components and buildings, property boundaries, lakes, streams, wells, and so on, as detailed in the table below. Contact us with corrections or additions to this data.
This set of tables below gives distance requirements between septic components and wells, streams, trees, property boundaries, lakes, etc. Common guidelines require at least 50' clearance distance between a well and a septic system tank or 150' between a well and a septic drainfield or leaching bed but you will see that different authorities may recommend different distances.
Local soil and rock conditions can make these "rules of thumb" unreliable. See "One and Two Family Dwelling Code, Section P-2510-Combined Seepage Pits and Disposal Fields," and Table P-2504, "Location of Sewage Disposal System." Other references are cited at the end of this table.
These septic information tables give typical required clearances for septic tank, soil absorption system (SAS), etc. but you will see that different authorities may recommend different distances.
These distances are for conventional onsite waste disposal systems which specify clearances presuming that effluent is being disposed-of after minimal treatment such as is received by a septic tank or cesspool. Advanced onsite wastewater treatment systems, such as those described by Jantrania and Gross (2006), permit substantial reduction in these clearances, depending on the level of treatment achieved.
Readers will find more details about septic system clearances and issues at NEIGHBORING SEPTIC SYSTEM PROBLEMS. Also see WELL CLEARANCES for required distances between wells and septic systems and other site features.
