Everyone that came told us we needed a new septic mound. Did some research and found Aero-stream...I am so glad I did. The mound was wet smelled like sewage and the grass was extra long and dark grass is curtain areas of the mound from the sewage fertilizer it. 6 months later, no super green growth spots, no wet spots and most of all no smell. Even after 2 weeks of rain the mound was super dry! A true money saver!
