Disinfected water from the CCB supplies the reclaimed water pump station. Chlorine Contact Basin 2 has two parallel plug-flow chlorination basins, each with gates at the influent and effluent ends of the basin. Either or both sides of the CCB may be in service as required to treat the plant flow. To properly operate the CCB and to provide chlorinated water to the Reclaimed Water Eastern Delivery System, the gates within the CCB must be functional. The effluent sluice gate on the western half of Chlorine Contact Basin 2 has an inoperable gate actuator and cannot be operated normally. The required repair will involve replacing the actuator and associated electrical items. We have reviewed the proposed costs and are of the opinion the costs are reasonable and fair.

Justification for approval of the PCM is presented in the following paragraph. The current design includes a turbidimeter that measures turbidity downstream of the reclaimed water pump station. Since flows have increased over the last year, treated water quality concerns related to fecal coliform counts have risen. The turbidimeter is required by the Texas Commission on Environmental Quality; however, it is not considered an accurate predictor of potentially high fecal coliform counts in the reclaimed water. Since fecal coliforms correlate better to Total Suspended Solids (TSS) than turbidity, it was recommend by CP&Y and agreed to by plant staff to add a low concentration TSS meter, which will provide operators more enhanced monitoring of the water quality in the reclaimed water system. We have reviewed the proposed costs and are of the opinion the costs are reasonable and fair. Please feel free to contact me should you have any questions. Sincerely yours, CP&Y, Inc. Michael F.
