1981 12 18 BAWA Minutes 11218-1 MINUTES OF THE REGULAR MEETING OF THE BOARD OF DIRECTORS OF THE BAYTOWN AREA WATER AUTHORITY December 18, 1981 The Board of Directors of the Baytown Area Water Authority, Harris County, Texas, met in regular session on Wednesday, December 18, 1981, in the Conference Room of the Baytown City Hall with the following attendance : 411 Robert L. Gillette, President Harry F. Hartman, Vice President Peter R. Buenz, Secretary *Dr. Robert E. Hill, Board Member Absent : Dan M. Mundinger, Board Member The meeting was called to order and the following business was transacted: Minutes Board member Buenz moved for approval of the minutes for the meeting held November 18, 1981 ; Board member Hartman seconded the motion. The vote follows : Ayes: Board members Buenz, Gillette and Hartman Nays: None Discuss Fluoridation Board member Gillette stated that he had spoken with several persons in the medical profession concerning fluori- dation of water. Not one of those persons expressed opposition to fluoridation of water. East Harris County Medical Asso- ciation will hold a meeting in the near future. At that meeting, the subject of fluoridation will be discussed and an official letter will be forwarded to the BAWA Board. A copy of a letter from Dr. J. J. Burianek, a member of Pediatric Associates of Baytown, was furnished to each Board member. In his letter, Dr. Burianek stated that recently he had attended the Texas Pediatric Society meeting in Corpus Christi at which time all pediatricians of Texas were cautioned to check water supplies for fluoride content . Dr. Burianek pointed out that the ideal level of fluoride is approximately 1 part per million. This level is safe and will cause no mottling of teeth. The cost for adding fluoride is approxi- mately $1. 00 per year per child and prior to connecting to 411 surface water, the well water being utilized contained 1 part per million concentration of fluoride. Board member Gillette stated that he was aware that there are individuals who object to fluoridation of water, but he was unable to obtain any literature or have anyone specifically mention the reason for the objection. 11218-2 Minutes of the BAWA Board - December 18, 1981 The Administration had gathered information from the Texas Department of Health which indicated that through funds authorized by Section 317 of the Public Health Service Act , a statewide drinking water fluoridation program for selected communities having a population of 1 , 000 or more is being administered. The Texas Department of Health will provide financial and technical assistance to those selected communities which indicate a desire to participate in the fluoridation program. The financial assistance will cover the costs of equipment , supplies for two years and installation. Since BAWA has no means of daily testing of fluoride content , funds will also cover the cost of lab equipment required. Should BAWA install this equipment using these funds, 411 an on-site inspection by the Texas Department of Health will be made to ensure that proper chemical dosages and optimum fluoride residuals are achieved throughout the distribution system. The only requirement for the funding will be to maintain an optimum level of . 7 mg/1 or . 8 mg/1 and submit four check samples each month to the Texas Department of Health for analysis. A report of fluoride concentration taken daily must also be added to the monthly report which is currently forwarded to Texas Department of Health. Richard Bosley emphasized that what is being proposed will simply bring the level of fluoride within range of what it was prior to converting to surface water. When Baytown was utilizing well water, the fluoride content was over the . 7 mg/1 or . 8 mg/1 but not enough to cause mottling of teeth. Mr. Bosley also stated that he had been receiving numerous calls from pediatricians and dentists requesting information on fluoride content. These individuals have expressed concern that the fluoride content is low. Board member Buenz moved to recommend to City Council that BAWA be authorized to proceed with application for funding from the Texas State Health Department to proceed with the installation of equipment necessary to bring BAWA water back up to the recommended level of fluorides; Board member Hartman seconded the motion. The vote follows : Ayes: Board members Buenz, Gillette and Hartman Nays: None Hear Report on Changes in Treatment Process to Reduce Levels of Trihalomethanes Norman Dykes, Director of Public Works/City Engineer, reported to the Board that by 1983, BAWA must comply with EPA requirements regarding trihalomethane content . The state will begin monitoring trihalomethanes in 1982 to provide a one year test period in order to allow time for the various entities involved to comply. The State has, as a courtesy, been monitoring BAWA water. Test results from • the summer indicate trihalomethanes in excess of 100 parts per million. At that time, the Administration consulted with the Texas Department of Health and their recommendation was to follow a plan based on what other water systems had done to reduce trihalomethanes. Based on that suggestion, Phase I of the plan was to change the point of application of 11218-3 Minutes of the BAWA Board - December 18, 1981 the chlorine. At that time, BAWA was pre-chlorinating. The addition of chlorine to water with a number of organics forms trihalomethanes; therefore, the point of chlorination was moved to the point of treatment where organics have already been removed. After this was done, the tests results were basically the same. The Administration then considered where to go with the second phase of the plan and based on comments from the State Health Department , EPA and other water systems, the decision was made to add ammonia to the water immediately following chlorination which will form chloramines. Chloramines have been found to be an effective means of disinfecting water. Chloramines combined with organics in water do not form trihalomethanes. An existing 411 chlorinator can be converted to add the ammonia. There will be a small amount of installation hook-up . A number of the lines that are in existence can be utilized, so the expense will be rather small. The installation charge submitted by A. G. Bailey Company is $4, 200 which includes complete installation, materials and labor. Ammonia is purchased in ton cylinders similar to chlorine. When utilizing ammonia to control development of trihalomethanes, 1/3 part ammonia is utilized. Mr. Dykes emphasized that this is a testing-type phase where the staff will be testing at different points of application for different concentrations and/or different combinations. Mr. Dykes stated that he would like to obtain Board consent to expend the S4, 200 and to have A. G. Bailey Company install the necessary equipment . Mr. Dykes stated that he has spoken with cities of Tyler, Huntsville, Houston and Harlingen and all have verified this method is being utilized and does work to reduce trihalomethanes. This method is also very economical . Board member Buenz moved to authorize the expenditure of funds to implement the addition of ammonia to the disin- fective process in order to reduce concentrations of trihalo- methanes; Board member Hartman seconded the motion . The vote follows : Ayes : Board member Buenz, Gillette and Hartman Nays: None Mr. Lanham reminded the Board that when the plant was being designed, Lockwood, Andrews & Newnam discussed this matter and indicated that space would be included in the plant in the event it should become necessary in the future to add facilities to treat the water by method of activated charcoal. This is a very expensive process in both cost of installation and cost to maintain . The Administration is aware of no cities in Texas that have taken that step. In response to an inquiry from the Board, Mr. Dykes stated that presently BAWA water contains 138 parts per million trihalomenthanes; safe limit is 100 parts per million. 41, Consider Change Order to Chisholm Trail Contract Rick French with the firm of Lockwood, Andrews & Newnam stated that the total change is for the amount of $11 , 905. 99. The first item is credit for return of an extra dishwasher in the amount of $1, 521. The second item is credit for restocking of check valves on backwash pump station for the amount of $8, 087. 51. The third item is on the cash allowance. 11218-4 Minutes of the BAWA Board - December 18, 1981 In the specifications, the contractor was required to allow $7, 800 for such things as carpeting, mini blinds, dedication plaque and hardware. Due to inflation this amount was exceeded in the amount of $1 , 399. 33. The fourth item is for the resistor banks for the backwash pump station, the transfer pump station and the forebay pump station which all have variable speed controls where the resistor banks are needed. During the original design phase, General Electric, at that time, was recommending that only the transfer pump stations have resistor banks located externally from the motor control center. Variable frequency drive varies the flow which was a relatively new concept and General Electric had not had a great amount of experience with this type flow. Therefore, General Electric had recommended that above a certain drive 410 the resistors be located outside the motor control center to alleviate heat build up. By the time shop drawings came in, General Electric had more experience and recommended that the smaller horesepower motors also have resistor banks located outside the motor control center to alleviate heat build up. Therefore, the consulting engineers had the resistor banks located externally for the three pump stations for which Chisholm Trail submitted an original change order of $16, 000. The consulting engineers began negotiations with Chisholm Trail and reviewed what had transpired. Upon making a detailed study of the shop drawings, the consulting engineers discovered that work had been performed unnecessarily due to non-coordination on the part of the contractor. The total change after that adjustment is $12, 665. The consultants feel that the contractor should be paid for this work since that was the additional cost for installation. There were no additional equipment costs because General Electric provided the equipment at no additional costs to BAWA. The fifth item is for electrical surge resistors. In the specifications for instrumentation some surge protection was specified. There was a high rate of failure; therefore, Bristol, the instrument manufacturer, recommended the use of a new product to eliminate surges and protect the instruments more efficiently. The consulting engineers concurred with that recommendation; additional surge protectors were installed for a change of $1 , 574. The final item is for repair of backwash pump bearings. One of the backwash pumps had a rag that was caught and wrapped around a propeller which did some damage to the bearings in the pump shaft . The amount of charge for this work is $5, 876. 17. When this work was being performed a cap was left off the motor which allowed water to seep into the motor and a bearing was ruined. The contractor replaced that bearing at his own expense. The backwash pumps had already been accepted when the other problem occurred making the problem BAWA' s responsibility. The total amount for change orders mentioned represent an add of $11 , 905. 99. The amount for total change orders for the entire contract is $251, 254. 08 or less than 2. 4% of the original contract costs. The typical amount for orders for a contract of this size is from 3% to 5%. *Dr. Hill present . 410 In response to an inquiry from the Board, Mr. French stated that the rag in the propeller was not a warranty item and since no one really could say how the rag came to be wrapped around the propeller, BAWA would be responsible. Board member Buenz moved to approve the change order amount of $11, 095. 99; Board member Hartman seconded the motion. The vote follows : 11218-5 Minutes of the BAWA Board - December 18, 1981 Ayes: Board members Buenz, Gillette, Hartman and Hill Nays: None Hear report from Lockwood, Andrews & Newnam, Inc. Richard Llewellyn , representative of Lockwood, Andrews & Newnam, Inc. , reported that the pressure test on the last portion of the transmission line was passed on December 15. The consulting engineers will be inspecting the interior of the transmission lines beginning the week of December 28. Angleton is presently working on cleanup items. There has been some problem with damage to butterfly valves which BAWA has taken the initiative to remove and replace one such valve and another has been ordered. Once internal inspection is completed, the line will be closed. Mr. Styner reported that Angleton has notified the consulting engineers that the line will be ready for inspection and that an answer is expected by December 22 . The engineers will respond that interior inspection will commence on December 28. There are approximately Si miles of interior pipe left to be inspected. The inspector will be looking for improperly reinforced joints, as well as mud and trash. If the inspector finds those conditions, the contractor will be requested to rework that particular joint . The treatment plant is essentially completed. The only problem with the plant is the problem with waterproofing. At present , the consulting engineers are working on that problem and attempting to determine the cause of the waterproofing failure and what can be done to correct the problem. Presently , there is 2% retainage on the contract which amounts to $210, 000. The consulting engineers recommended that the retainage be reduced to $50, 000 which would be sufficient to cover additional work that may be required. Board member Hartman moved to authorize the reduction in retainage to $50, 000; Board member Buenz seconded the motion. The vote follows : Ayes: Board members Buenz, Gillette, Hartman and Hill Nays: None Consider Award of Bids for Purchase of One 3/4 Ton Truck and One 1/2 Ton Truck The Board had been furnished tabulations of bids for 3/4 ton and 1/2 ton trucks. Copies of tabulations are attached to the minutes as Attachments "A" and "B" respec- tively. Bids were taken for one 3/4 ton truck with warning 410 light and roof spotlight options. The low bidder was Baytown Motors with a base bid of $9, 077. 12. The total bid with all options is $9, 276. 62. The Administration recommended low bidder. The other bid received was for 1/2 ton truck with options of air conditioning, heavy duty springs and tool box. Low bidder was Baytown Datsun with a base bid of $6, 545. The total bid with all options is $7, 451. The Administration recommended low bidder. The 1/2 ton truck will be utilized by the plant superintendent which is the reason for air conditioning and the fact that a smaller truck was ordered to conserve on fuel. 11218-6 Minutes of the BAWA Board - December 18, 1981 Board member Buenz moved to accept the Administration ' s recommendation to purchase the 1/2 ton and 3/4 ton trucks with options from the low bidder in each case; Board member Hill seconded the motion. The vote follows : Ayes : Board members Buenz, Gillette, Hartman and Hill Nays: None Adjourn There being no further business to be transacted, the meeting was adjourned. 1 4, / Peter R.
