Committee hears that poor siting and neglected maintenance are main failure modes for drip systems

Terry described common installation and maintenance failures that reduce system longevity: plowed drip lines across drainage swales, exposure from head cuts, and installation in closed depressions that pond after heavy rains. He warned these are often not soil-quality failures alone but errors of site selection and follow-up.

"It got so bad that the head cut, that water passing through that drainage way, started to eat back up into the drip zone," Terry said, describing a site where the drip zone was progressively undermined. He recommended correct siting, ongoing maintenance, and appropriate bonding to ensure fixes when conditions change.

Committee members asked whether these problems persist. Terry said he hopes the number is lower now but emphasized ongoing monitoring and realistic reserve/duplication capacity are prudent when communities rely on decentralized systems.
