Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Septic tanks and dry wells are the same thing. | Septic tanks and dry wells serve different purposes. A septic tank is designed to treat wastewater from a home or building, while a dry well is used to manage stormwater runoff. |
| Dry wells can be used for sewage disposal. | Dry wells should never be used for sewage disposal as they do not have the necessary treatment processes that septic tanks have. This can lead to contamination of groundwater and surface water sources. |
| Septic systems don’t require maintenance or pumping out regularly. | Regular maintenance and pumping out of a septic system is crucial in preventing backups, clogs, and costly repairs down the line. Neglecting this can also lead to environmental damage if untreated wastewater leaks into nearby water sources or soil. |
| All properties with septic systems need a dry well too. | Not all properties with septic systems require a dry well as it depends on factors such as soil type, slope of land, rainfall patterns etc., which determine how much stormwater runoff needs to be managed on-site through infiltration methods like dry wells or other techniques like rain gardens etc. |
| Installing either system requires no permits or regulations. | Both installing a new septic system and constructing/installing a new dry well typically require permits from local health departments/authorities who oversee onsite wastewater management practices in their jurisdiction/regional area/country/state/province etc., depending on where you live. |
