Guidelines for Planting Over Septic Systems and Septic Fields: Homeowner Guide to Planting of Trees, Shrubs, Gardens, Grasses, Ground covers over the Septic Tank, Drainfield or Leachfield. This article explains the types of plants that should or should not be planted over or near septic fields or other septic system components. Planting trees, shrubs, and even some ground covers over septic system components are causes of septic system failure in the drain field, leach field, seepage bed, or similar components. Planting fruit trees, or vegetables (or anything else edible) over the septic drainfield might produce food that is unsafe to eat: see SEWAGE CONTAMINANTS in FRUIT / VEGETABLES for details.

Planting Guidelines for Septic Drainfields, Mounds, Raised Beds, Septic Tanks and other Septic Components
The following table of native (to New Zealand) or introduced species of grasses lists species that are considered suitable for planting over an evapo-transpiration system and should be acceptable over a mound system or conventional drainfield as well. Note that other native species local to your area might also be suitable. 
Power augers or Roto Rooters™ for plumbing drains can be an effective way to remove a blockage or clog in a drain line.
But if your plumber shows you a tangle of roots when s/he pulls the augur back up the drain line, you should expect that additional repairs will be needed soon.
Even if you pull roots out of the blocked pipe section, the fact that they were in there means a tree, shrub, or other plant has invaded the area and its roots remain outside the just-un-clogged pipe. You can count on the roots re-invading the pipe (and getting at those nutrients) soon. So de-rooting a clogged drain line is a temporary fix.
