City Council Water & Sewer Subcommittee <br />May 15, 2003 <br />Page 11 <br /> <br />there are 51 valves, and attached to each valve is an actuator that makes the <br />valve work. Mr. Campbell said that ten, out of the fifty one, are control valves <br />that modulate the flow coming out of the filter. That flow is based on computer <br />signals that are sent to the modulating valve actuator to make sure that the <br />water coming out of the filters is maintained at a proper flow rate. Mr. <br />Campbell said the old ones were piston actuated and would hang and stick. <br />He said that actually, there were two kinds, there are valve actuators that just <br />open and shut a valve, but this one actually throttles the valve and maintains <br />a certain fixed, or semi-fixed position. He said that the new ones are a different <br />kind and they are much more capable of controlling the effluent flow and this <br />is what we are putting on. He said the city is actually buying controllers <br />instead of valves. Mr. Campbell said that they are using the old valves and he <br />anticipated that they might have to replace a valve or two; but so far they have <br />not had to do that. He said some of these valves are 35 to 40 years old. <br /> <br />City Manager Malone passed out a memorandum regarding Councilman Plata' s <br />Recommendation Number Four: ~Cut operators manning the water production <br />plant from 2 people per shift to 1 person per shift". The City Manager stated <br />that the mission of the Water Treatment Division of the Utilities Department <br />is to produce potable drinking water while protecting the health of the people <br />we serve by treating the drinking water properly while meeting exacting state <br />and federal standards as encompassed in the Safe Drinking Water Act and other <br />regulations, to ensure the protection of the health and safety of our employees, <br />and to perform this task as economically as possible. <br /> <br />City Manager Malone said the size and complexity and operating conditions <br />for the water treatment plant in Paris, Texas, at Lake Crook are considerably <br />different than those of the facilities in cities that have been furnished by <br />Councilman Plata for comparison purposes. He noted that the representatives <br />of OMI, in making their presentation, advised that each city's operation was <br />different. <br /> <br />City Manager Malone stated that there are very good reasons why the Utilities <br />Department is staffed as it is. He said that staff size has developed over many <br /> <br /> <br />
