Sewer Maintenance Hole
Functions of a Maintenance Hole
A maintenance hole provides several functions, such as to,
- conduct inspections
- connect two sewers when there is a change of grade or alignment or size
- provide a junction where two or more sewers meet
The useful life of a sewer maintenance hole will vary considerably due to a range of environmental factors. A life of 50-100 years is typical in some areas.
