House Connection Manhole

房子连接人孔是什么意思？

A house connection manhole is a manhole made in support of a large house connection, such as that for a 12-inch sewer line. Typically, house connection manholes are new construction.

Prefabricated manhole units are purchased and assembled on site. The installation of the manhole unit requires street-level excavation to access the appropriate sewer main. The installation of the lateral, if not extant, can be performed trenchlessly.

A house connection manhole isn't common. Most household connections are a simple riser, curb, or spur connection made by way of handholds. House connection manhole, however, is required when a large (such as 12 inches) lateral connects to the sewer main. Typically, these connections are required by larger multifamily development.

Prices for new prefabricated manholes vary but may exceed $2000. The cost of installation and other incidentals also varies and who pays for this additional manhole (labor and materials) may vary from jurisdiction to jurisdiction.
