TCEQ Restrictions
According to the TCEQ, Emergency Preparedness Plan, 290 Subchapter D, a water distribution system shall maintain a minimum pressure of 35 pounds per inch square at all points of the distribution network, in addition to a minimum of at least 1.5 gallons per minute per connection. The distribution network was modeled and as previously mentioned, a hydraulic analysis was performed with the five different materials. As shown in the topographic profile, the highest point of elevation is 4119.0 feet at the centerline of the proposed pipe. Thus, the lowest pressure is expected to occur at this point. Figure 6 shows the pressure obtained for the five different materials from station 72 + 00 to 80 + 00 where the lowest pressure was expected to occur.
