Benefits

Less sand, lower costs

The pipes rest on only 35 cm of filtering sand vs. 60 cm for regular installations

Smaller mound

As it requires 25 cm less sand, the mound is shorter.  If the limiting layer of your site is elevated, you’ll have a smaller, lower-profile hump on your land.

Better water distribution

The PVC pipes inside the Advanced Enviro))Septic distribute the water over the entire length of the field rather than just at the start
