This mixed-flow turbine boosted power efficiency by changing the flow of water to move inward and downward through the turbine, thus mini­ mizing friction and turbulence .. Francis also designed a 2-million gallon res­ ervoir in an elevated section of Lowell, and laid a 6,000-foot, 12-inch main pipe to the city proper to deliver sufficient water to fight up to two mill fires at once. Once this reservoir was operational, Francis further designed and in­ stalled a sprinkler system to furnish up to 400 gallons per minute to the roofs of the mills. This innovation was so successful that insurance companies began requiring sprinkler systems in all fire-prone areas of industrial buildings.
