The riser section has alternately adjacent threaded sections and grip sections in appropriate areas along the riser for height adjustment of the sump in that, at a desired height, the riser section may be cut off to conform to that desired height. To form the sump the riser section is threadably engageable with the base, the access cover is threadably engageable with the riser section, and the inspection cover is threadably engageable with the access cover.
