That the City Council approves the agreement between the City of Georgetown, Texas and TIPS Incorporated Engineering, for services related to the installation of radio control and monitoring telemetry equipment on existing water distribution systems, and all backup information attached hereto and incorporated herein as if fully set forth at length. SECTION III. That the Mayor is hereby authorized to execute the installation agreement and City Secretary to attest. PASSED AND APPROVED this /Uh day of Vvb-U , 1989. APPROVED: MAYOR ATTEST: CIT RETARY IPS INCORPORATED i i Mr. James Briggs, Director May 24, 1989 Public Utilities City of Georgetown j P.O. Box 409 Georgetown, TX 78627 Dear Mr. Briggs I Per verbal inquiry forwarded by a mutual associate, Mr. G. Michael Click, find enclosed a proposed bill of materials for the hardware and an estimate of the engineering services required,~ in TIPS estimation, to upgrade and modernize the communications capability and control. reliability of the Park Water Plant and related pumping station{s} in the Georgetown area;- viz: o Computer Hardware . .'. . . . . $12,000 o Radios & Antennae . . . ... . . $ 6,000 o Isolation & Interface Hdwr $ 3,000 I o Software Configuration . $18,000 j o Installation & Startup . . . $ 3,000 o Training & Documentation . $ 2,000 Est Total . . $44,00 The proposed hardware will significantly reduce the electro -mechanical complexity of the .existing installation by eliminating signal converters, telephone telemetry devices, strip chart recorders, and other maintenance - intensive items. By reducing the total number of components, the network of inter -connecting wiring will be reduced thus eliminating much of the antenna effect that now leads to equipment damage and malfunction during inclement' weather. Thus, overall system maintenance will be reduced. The proposed upgrade equipment is microcomputer -based. As a result, a flexible interface to your existing PC will be provided to facilitate usage reports, time -tagged alarm reporting, and spread -sheet based analyses of operations to thus enhance. the overall usability of the system. The proposed platform will eliminate electrical interference effects that• now impact the current system by utilizing: state-of-the-art opto-isolation devices and surge protectors in`'key "areas of theinstallation. i 1 2700 Porker Drive • Georgetown, Texas 78628 • (512) 863-3653 • (800) 242-8477 Georgetown Water system Proposal May 24, 1589 Page 2 The software on the system will be configured to provide, in addition to the aforementioned reports,secure clock -driven routines to control pumping activity to take advantage of lower electrical rates during off-peak hours. Many energy management systems that TiPS has worked with in times past provide this functionality. The enclosed proposed bill of materials and estimated casts for the system hardware will provide microcomputer - based control equipment for three locations: (1) Downtown; (2) Park. Ground storage; and (3) Central Plant. Communication coordination will take place at Central Plant so approximately 40`% of the computer hardware will reside at that location with the rest split between the other two locations. Prolog Corporation is presented ,as a potential' supplier of the computer hardware because. (1) Quality reputation as evidenced by 5 -yr warranty on their boards; (2), Compatibility with existing PC software; and (3) Experience by TIPS in utilizing Prolog solutions over last 15 years. TIPS' warrants its software to be defect free for one year from the systems commissioning date based on project specification parameters and mutually -accepted performance criteria. Radio communications per the attached hardware' specification will provide reliable data flow and control coordination with outlying points. Full duplex units will be located at 4 sites (Ref Drawings Attached) including a master station located at Central Plant:. Satellites include: (1) James Street; (2) Downtown; and () Park Ground Storage. Future expansion capability is ensured by adding satellite units. Othercomputerand interface subsystem suppliers that offer products that could be adapted to Georgetown's requirements include ADAC Corporation, Hewlett 'Packard, Action' Instruments, and IBM (Industrial Gearbox).' Some suppliers of radio systems include Repco, Inc (407-843-8484) and Granger, Inc (408-432-3265). A number of firms offer optically -isolated interface modules such as OPTO-22, Crydom, Gordos, and Moore Industries. Independent of the source of hardware supplier there emerge four ideas central to the success of the proposed installation: (1) utilization wherever possible of optical isolation to stop the propagation of electrical disturbances'; (2) computer-based data acquisition and analyses to monitor and/or control operations; (3) Data interchange between computers and remote sites via radio to ensure timely and accurate information dissemination; Georgetown Water System Proposal May 24, 1989 Page 3 and (4) proper power and grounding practices to protect equipment. The details on the implementation of these four central ideas will be issued in a detailed specification a the first phase of the project. As part of the specification, a step-by-step switch - over procedure on converting from the present system to the new system will be presented so as to minimize installation impacton on-going operations. The specification will include an operator training plan. Final system documentation including computer software listings will be provided on magnetic media and/or on -size interconnect and logic drawings. Find enclosed a brochure about TiPS, Incorporated that explains in some detail the background of the Company and its direction. As control engineering in the chemical and related industries is a mayor focus of the company, TiPS is confident it can bring to bear the talent and experience to make a difference to your operations. TiPS has been fallowing the troubleshooting activities of Mr. Click and has consulted with Mr. Click' in an effort to provide continuity and backup to his efforts. In closing, TiPS stands ready to provide the support and systems integration services to ensure a quality installation for the City of Georgetown and would welcome the opportunity to discuss this proposal in more detail.

Engineering, located in Georgetown. These individuals were very helpful in reviewing our current system and making recommendations to upgrade and modernize to a more state-of-the-art system of water system control. The proposal that is attached, shows a break down of costs and other information related to the telemetry equipment that we are proposing for your approval. As you will note, this particular equipment also allows us to take advantage of lower electric rates by the use of energy management. This particular system also allows the City to add and delete stations at various points in the system with relative ease, therefore not looking us into a small monitoring network. After thoroughly reviewing the proposal as presented and investigating the background performance of this equipment, I am convinced that this operation will be the most effective fop control of our water system today and into the future. TIPS INC. Engineering, has also mentioned that they would assists the City in locating another water utility that has extensive capital outlays in telemetry equipment matching our old equipment. This will assist us in finding a buyer for this equipment, and the expected price we would be able to receive for our equipment, was approximately 80% • list which is in the range • $25,000.00* Therefore, City staff recommends the installation of new telemetry equipment as proposed by TIPS INC. Engineering, for the lump sum amount not to exceed $48,000.00. Funding Source: Water Capital Projects attachments
