FUNDING SOURCE: Funds are available in account number 200-43360-534-0 BACKGROUND: The Environmental Protection Agency promulgated two new drinking water regulations that impact the City's water treatment plant on December 16, 1998. The rules are the Interim Enhanced Surface Water Treatment Rule (IESWTR) and the Disinfectant By Product Rule (DBPR). The City must comply with the requirements of both regulations by January 1, 2002. IESWTR is the extension of the original Surface Water Treatment Rule and will impose more stringent finished water turbidity requirements. The new finished water turbidity requirements are 0.30 NTU (nephelometric turbidity units) maximum finished water turbidity in 95% of samples / month and no turbidity readings exceeding 1.0 NTU. Additionally, rigorous monitoring of filter operation is required. Except for the additional monitoring Grapevine's plant currently performs in compliance with this new rule. The requirement for decreased disinfectant byproducts will impact the operation of the Grapevine plant. One of the major requirements of the rule is the removal of certain total organic carbons. With the current technique, the City's treatment may not meet the required percent of total organic carbon removal. The City may use "enhanced coagulation" or other treatment processes such as "ozonation" to remove the required percent of total organic carbon. May 10, 2000 (2:21 PM) This study will evaluate the water treatment plant process to determine the possible effects of these regulations on the plant's operation. The objective of the plant evaluation will be to assess different treatment methods to meet the total organic carbon removal and other upcoming regulation requirements. Also, taste and odor problem reduction and manganese reduction will be evaluated. Freese and Nichols has designed all three phases of the Grapevine Water Treatment Plant and is very familiar with the treatment process. They have performed similar studies for the cities of Arlington, Longview, Beaumont, Fort Worth and Tarrant Regional Water District. Based on Freese and Nichols' familiarity with the Grapevine Plant and vast experience statewide conducting similar studies staff recommends approval of the contract. /MS 0:\agenda\051600\Eng.Serv_V TP.agm May 10, 2000 (2:21 PM) A C E N T U R Y O F S E R V I C E FREESE•NICHOLS February 9, 2000 Mr. Matt Singleton Assistant Director Public Works/Operations City of Grapevine P.O. Box 95104 Grapevine, Texas 76099 Re: Proposal for Implementation of Two New Safe Drinking Water Acts (SDWAs) Regulations City of Grapevine Water Treatment Plant OFF99041 /GP64/ 1160 Dear Matt: As discussed on Friday, February 4, 2000, Freese and Nichols, Inc. is pleased to submit this proposal for providing professional engineering services to the City of Grapevine for the implementation of two newly promulgated Safe Drinking Water Acts (SDWAs), especially the total organic carbon (TOC) removal requirements of the Disinfection Byproducts Rule (DBPR). PROJECT UNDERSTANDING On December 16, 1998, the EPA announced two new drinking water regulations, the Interim Enhanced Surface Water Treatment Rule (IESWTR) and DBPR, which may impact the City's water treatment plant. The City must comply with the requirements of both regulations by January 1, 2002. The IESWTR is the extension of the original Surface Water Treatment Rule (SWTR) and it will impose more stringent finished water turbidity requirements. The new finished water turbidity requirements are: 0.30 NTU maximum finished water turbidity in 95 % of samples per month and no turbidity readings exceed 1.0 NTU. Also, the IESWTR will require rigorous monitoring of the filters. The requirements for the DBPR are relatively complex and they %vill impact the City's water treatment plant. One of the major requirements of the DBPR is removal of certain total organic carbon (TOC). With the current treatment technique, the City's treatment may not meet the required percent of TOC removal. The City may use "enhanced coagulation" or other treatment processes such as "ozonation" to remove the required percent of TOC. The other major requirements of the DBPR are: 1) more stringent limits of total trihalomethanes (TTHMs) and total haloacetic acids (THAAs), 2) disinfection profiling and benchmarking, and 3) more rigorous monitoring and reporting. We recommend that the treatment plant processes be evaluated to determine the possible effects of these regulations on the City's water treatment plant operations. The objective of the plant evaluation will be to evaluate different treatment methods including ozone to meet the TOC and other upcoming regulations requirements. Also, the taste and odor reduction by ozone treatment will be evaluated. Freese and Nichols. Inc.
