stormwater vault maintenance ideas???
(OP)
This stormwater vault is 22,800 sqft under the parking areas for 100yr floodplain compensation. The trouble is that it needs to be only 2.5 ft. deep which raises a flag about maintenance to everyone(not tall enough for someone to move freely around inside). I need some ingenious ideas about maintenance procedures and design(manholes etc.). Thanks!

You should have a minimum of 2 access points for ventilating the area and for emergency escape routing.

In terms of meeting the maintenance needs, consider:
1. Regular cleaning and sediment removal: plan enough removable grates that the areas between the grates can be pressure jetted, and construct the floor of the vault with some slope so that gunk can be jetted to sumps, which could be vactored.
2. Sumps & flow control risers: requires overhead access opening (standard 2' diameter manhole lid could work).
3a. Structural inspections: This would be tough with a low ceiling vault. Video survey might be the way to go
3b. Structural repairs: If settlement or damage to the structure could occur, then it might be necessary to repair the structure. This is where removable top slabs would be useful.
Talking and coordinating with the party responsible for maintenance should be part of the design.

You know sometimes the result of the analysis is that because of time, money, space or other annoying elements of reality, the project won't work. Maybe in this case, the problem is keeping the mud out of the tank, rather than creating access to remove it once it is in there. How about one or more easily accessible settling ponds to collect sludge before overflowing the water into the tank area? If they are lined like swimming pools it really won't matter if they are poking down into the water table.
