== Composite manholes == Composite ([[fiberglass]]) manholes are commonly used in applications where infiltration, exfiltration, or corrosion by [[hydrogen sulfide]] (from [[sewer gas]]) are a concern, or where structures need to be factory integrated into a manhole before placement. In these manholes, the entire underground enclosure is constructed of some composite material, in addition to the cover. Structures that can be integrated into composite manholes include: * Flow inverts<ref name=" Manhole inverts ">{{cite web|url=http://www.containmentsolutions.com/wp-content/uploads/LIT-MAN-Manhole-Brochure.pdf|title=Manhole inverts|publisher=Containment Solutions|access-date=2013-03-07|archive-url=https://web.archive.org/web/20150403115417/http://www.containmentsolutions.com/wp-content/uploads/LIT-MAN-Manhole-Brochure.pdf|archive-date=2015-04-03|url-status=dead}}</ref> * [[Flume]]s<ref name=" Flow measuring flumes ">{{cite web|url=http://www.openchannelflow.com/products/manholes/flow-monitoring/flumes|title=Packaged Fiberglass (FRP) Flume Manholes|publisher=Openchannelflow|url-status=dead|archive-url=https://web.archive.org/web/20130325002625/http://www.openchannelflow.com/products/manholes/flow-monitoring/flumes/|archive-date=2013-03-25}}</ref> * Drop structures from higher elevation flows to lower elevation discharge pipes * [[Weir]]s<ref name="Manhole weirs ">{{cite web|url=http://www.openchannelflow.com/products/manholes/flow-monitoring/weirs/|title=Packaged Fiberglass (FRP) Weir Manholes for Flow Monitoring|publisher=Openchannelflow|url-status=dead|archive-url=https://web.archive.org/web/20130919084241/http://www.openchannelflow.com/products/manholes/flow-monitoring/weirs/|archive-date=2013-09-19}}</ref> * Storm water screening structures<ref name=" Storm water structures ">{{cite web|url=http://www.openchannelflow.com/products/manholes/storm-water/|title=Fiberglass (FRP) Storm Water Manholes for Initial Oil, Grease, Sediment, and Debris Collection|publisher=Openchannelflow|url-status=dead|archive-url=https://web.archive.org/web/20130307132910/http://openchannelflow.com/products/manholes/storm-water/|archive-date=2013-03-07}}</ref> * [[Sewage]] grinders<ref name=" Sewage grinders ">{{cite web|url=http://www.openchannelflow.com/products/manholes/grinder/|title=Fiberglass (FRP) Grinder Manholes integrating grinders from JWC, Franklin Miller, MonoFlo, and more|publisher=Openchannelflow|url-status=dead|archive-url=https://web.archive.org/web/20130828234339/http://www.openchannelflow.com/products/manholes/grinder/|archive-date=2013-08-28}}</ref> * Energy absorbing structures to dissipate undesirable flow stream turbulence or velocity<ref name=" Energy absorbing structures ">{{cite web|url=http://www.openchannelflow.com/products/manholes/energy-absorber/|title=Fiberglass Energy Absorbing Manholes for Controlling Excess Line Velocities|publisher=Openchannelflow|url-status=dead|archive-url=https://web.archive.org/web/20130307131247/http://openchannelflow.com/products/manholes/energy-absorber/|archive-date=2013-03-07}}</ref>
