There is a broken section of the vehicle apron that requires attention to make it safe. It appears to be because of consolidation settlement of the sewer main beneath the apron. A number of years ago [in early 1990's] the TDC placed the Maratoa relief sewer along Hirangi Road and parts of the line backfill settled over time. This appears to have happened beneath this section of the vehicle apron and now it has broken because of lack of subsoil supporting. It may be prudent to check the sewer main itself to see if there is any ingress into the pipe and that water from the surface has not found a way into the sewer main and eroded soil into the pipe. Some backfill is needed to immediately to make the berm area safe.
