Unwilling to risk losing what remained of Jango Fett's blood, the main source for producing the Fett clones, one of the 501st's primary objectives was to capture a container that held a sample of Fett's DNA. After storming Tipoca City and retrieving the container, the 501st brought their progenitor's blood sample to a landing platform an Imperial shuttle awaited them. From there, the shuttle took Fett's DNA off planet to safety while the 501st fought on against their rebel brethren. After gaining further ground from outside the city, the 501st went on to fulfill its next primary objective—destroying the Kaminoan life support systems in order to kill all of the rebel clones that had not yet been decanted, thus preventing the Kaminoans from raising more Anti-troopers against the Empire in the future. Despite being protected by a numerous elite ARC troopers, the rebel clones failed to prevent the 501st from killing the undeveloped clones within the facility. 
Even for Romans, private access to water came at a price. Homeowners who could afford running water paid for the service based on the diameter of their access pipe, a not entirely foolproof billing system. There are records of homeowners slyly installing wider pipes than those for which they paid. This scam led to the invention of the calix, a sleeved pipe fitted into the wall, which was decorated to prevent forgeries or alterations. They were also used in the castella aquarum, the tanks from which water was distributed to different parts of the city. Despite regulation, some Romans tried to steal water from the source and would drain off water from the aqueduct or bribe the aquarii to do so. In the first century . the senator Sextus Julius Frontinus mentioned this practice in his treatise De aquaeductu as “fraus aquariorum” : plumbing fraud.
