n.— «Grit pits are pits about 10-feet-by-10-feet wide that run under main sewer lines and catch debris filtered through the main line. The purpose of the plastic-walled pit is to collect debris that would normally accumulate inside the main sewage lines, causing backups and overflows.» —“Grit pits to help with sewer debris” by Luke E.
