Method for Installation of PEHD Manholes

- a technical report with 29 self-explanatory Figures -


1. HDPE Manhole & Chamber Design

PEHD Manhole and Chamber design stipulates various manufacturing configurations dependent upon actual site conditions. A number of factors including water table height, depth of cover and backfilling materials have significant impact on base configurations.

Where PEHD Manholes and chambers will be installed in areas with high ground water levels, a double bottom construction is recommended, which has to be filled with liquid concrete at the job site. In the case of the double bottom type there are two openings in the upper bottom one is for the filling of the liquid concrete and one is for the venting during the filling process. These openings need to be closed after filling and hardening of the concrete with covers.
