April 10, 2018 — Modification to Wastewater STD DTL S-501 .1 & S-701 : Riser Height Wastewater Manholes

Denver's Department of Transportation & Infrastructure Wastewater Management crews have been supporting Street Maintenance by raising and lowering manholes for their paving operations program. We are requesting that all City and County of Denver Project Managers either in Design or during the submittal process modify the maximum riser height according to the redlined STD DTL S- 501.1 & S-701. This applies to areas that are within the City and County of Denver right-of- way.

The modification will minimize the need for the Wastewater Management crews to plasma cut the ring to lower the manhole and they will be able to simply remove the two risers to obtain the depth required for milling operations. This also eliminates the need to haul additional equipment and has a significant effect on reducing the time it takes to prepare the road for Street Maintenance paving operation.
