BAWA is a water authority created by the Texas Legislature to supply water for the City of Baytown (City) and surrounding communities. BAWA services a total of eight customers with the City as the largest customer, generating approximately 87% of BAWA's annual sales. BAWA is a separate legal entity; however, it is considered a component unit of the City. Since it began operating, BAWA has not experienced shortages of its raw water supply to the plant or interruptions of service to its customers. REVENUES The 2018-19 proposed budget estimates sales of $13,816,896 for an average of 13.5 million gallons per day (MGD). Fluctuations in rainfall amounts can significantly impact actual sales. The existing rate structure of $2.74 per 1,000 gallons for the City of Baytown and $2.78 per 1,000 gallons for customers outside the city will increase to $2.82 and $2.86 respectively, effective October 1, 2018. This would cover the increased cost of operations, including debt service, the purchase of raw water, and provide funds for future capital projects. This increase in rates is expected to generate $398,565 in additional revenue. EXPENDITURES Total operating expenditures for the proposed 2018-19 budget are $6,791,521 which is an increase of $75,773 from the 2017-18 budget. An increase of $333,593 over current year estimate in the untreated water supplies is included in the budget due to the City of Houston's raw water supply contract. This budget includes a transfer of $350,000 to the General Fund for an indirect cost allocation to reimburse the City for administrative services such as Human Resources, Fiscal Operations, Legal and Information Technology Services. Highlights of major operating changes are as follows: • Increase in personnel services $ 43,699 • Decrease in supplies (16,863) • Increase in maintenance 1,000 • Increase in services 47,937 • Increase in capital outlay 85,000 • Increase in transfers out -capital improvements 3,790,159 Raw Water Supply Cost BAWA purchases raw water from the City of Houston. The raw water supply contract with the City of Houston is in effect through the year 2040, and sets the maximum amount of raw water to be delivered to the BAWA plant at 20 MGD without penalties. The surcharge for water purchased over the 20 MGD is nominal at this time. BAWA received notice of a rate increase (2.8%) from $0.6821 to $0.7012 effective April 1, 2018. The annual rate adjustment is intended to help cover the City of Houston's cost increases that impact the provision of safe, clean drinking water and the collection and treatment of wastewater. This includes operational costs as well as the costs involved in repairing portions of the City of Houston system's aging infrastructure. Exhibit "A" BAYTOWN AREA WATER AUTHORITY MAJOR BUDGET ISSUES FISCAL YEAR 2018-19 Debt Service - The transfer to cover the debt service requirement for the proposed 2018-19 budget is $2,429,518. The Authority awarded a construction contract to build the BAWA East Water Treatment Plant and due to the length of time for construction, 27-36 months, the Authority chose to issue bonds in two parts. The combination of bonds and operating funds totaling $28 million, was issued for the first year. The second issue, $18 million in bonds, will be issued in the fiscal year 2018-19. CAPITAL IMPROVEMENT PROGRAM The Capital Improvement Program for BAWA is funded through the issuance of revenue bonds, grants, and revenue from operations. BAWA East Water Treatment Plant '$6,016,617 Development of a six (6) million gallons per day (MGD) surface water treatment plant south of Interstate Highway (IIT) 10 and west of SH 99 along the Coastal Water Authority (CWA) Barbers Hill Canal. The design will provide for the ability to expand the plant based on future water demands and allow the plant to convert to salt water treatment (desalinization) ensuring long term viability. Construction is expected to begin in October 2017. Annual Operating Impact: Non -Operational for FY2019 High Service Pumps $923,138 Replace all four high service pumps with new pumps. The new pumps will have a firm capacity of 24,000 gpm (34.5 MGD) at 175 -ft TDH. Annual Operating Impact: Preventative maintenance cost projected at $15, 000 for FY2019. Filter Scour $1,114,000 This project will provide more efficient backwash with 40-50% less backwash water and will extend the life of the filter media. (Cost savings less energy and water use) Annual Operating Impact: No anticipated operating cost for FY2019. East Transmission Line $1,650,000 This is for the design of the transmission line that will go from the new Water Treatment Plant to provide water to the City Annual Operating Impact: No anticipated operating cost for FY2019 5 Exhibit "A" BAYTOWN AREA WATER AUTHORITY MAJOR BUDGET ISSUES FISCAL YEAR 2018-19 WORKING CAPITAL In order to maintain fiscal stability, governmental entities maintain a working capital balance to meet daily liquidity needs. Appropriate levels of working capital vary from entity to entity based on the relative impact of particular circumstances or financial conditions. Working capital is defined as current assets (e.g., cash, investments and accounts receivable) less current liabilities (e.g., accounts payable). In the 2018-19 proposed budget, BAWA's working capital level at year end is projected to represent 235 days of operating expenditures; a contingency line item of $75,000 is provided; plus we are able to transfer out $5,790,159 to BAWA's Capital Improvement Project Fund (CIPF). The $5,790,159 will be available for funding future capital projects. 6 Exhibit "A" 3070 BAYTOWN AREA WATER AUTHORITY — PROGRAM SUMMARY Program Description BAWA operates and maintains a 26 Million Gallon per Day (MGD) surface water treatment facility. It has a projected raw water flow of 13.25 MGD and projected finished water flow of 13.5 MGD for fiscal year 2017-18. BAWA currently serves 8 surrounding area customers, including the City of Baytown, which uses 87% of BAWA's production. Operations personnel ensure the facility's compliance with the Texas Commission on Environmental Quality's (TCEQ) Rules and Regulations for Public Water Supplies. BAWA provides its customers with high quality, safe drinking water and consistent water pressure for fire protection. Major Goals • Maintain water quality necessary to be classified as "Meeting Optimum Corrosion Control" by TCEQ. • Maintain "Superior Public Water System" status. • Maintain standards for the Texas Optimization Program - a voluntary program through TCEQ that promotes the optimization of surface water treatment plants, by identifying and addressing the various factors that limit performance in order to lower the risk of waterborne disease. • Develop and maintain a staff of highly trained water professionals through continuing education classes and hands on training. Major Objectives • Produce 13.5 MGD of finished water. • Maintain finished water turbidity (haze measurement) consistently < 0.1 NTU. • Maintain compliance with all TCEQ and EPA regulations.
