Mary Trahan’s computer screen at the Consolidated Waterworks District No. 1 building in Houma lights up like a Christmas tree.

Those lights, which illustrate the fifth-largest public waterworks system in the state, are about to get a lot brighter.
The emergency rule sent down Nov. 6 dictates that all state water supplies must maintain chlorine concentrations of 0.5 milligrams per million gallons of water, up from previous levels of 0.2 per million.
