Executive Summary The LOTT Clean Water Alliance provides wastewater Many of these projects are large-scale, span multiple treatment and reclaimed water production services years, and require substantial investment. At the for the urban areas of Lacey, Olympia, and Tumwater same time, LOTT must operate its treatment facilities in north Thurston County. LOTT’s complex system of 24 hours a day, 7 days a week, 365 days a year, to treatment and conveyance facilities represents one of ensure that wastewater is properly treated and our communities’ largest regional investments, worth cleaned before it is released into the environment. To an estimated $750 million. support all this, LOTT must carefully manage financial resources, planning ahead with a long-term view that provides flexibility to adjust to changing conditions, while minimizing impacts to ratepayers. LOTT uses a six-year financial planning period, and 2017 and 2018 represent the last two years of the current planning cycle. For 2017 and 2018, LOTT is preparing a biennial budget. LOTT’s Board of Directors approved the shift to a biennial budget format in 2016. This document outlines LOTT’s two budgets for the 2017-2018 biennium – a Capital Budget and an Operating Budget. The Capital Budget includes costs to replace, upgrade, or rehabilitate existing facilities and to build new system capacity. These projects LOTT’s complex system of treatment facilities represents one of our communities’ largest regional investments. are described in the Capital Improvements Plan, also included in this document. The Operating Budget To sustain the communities' investment in the existing contains all the costs necessary to operate LOTT’s system and accommodate future service needs, facilities and provide related services. The following LOTT operates under a continual cycle of planning, table shows a combined summary of both operating designing, and completing numerous capital projects. and capital revenues and expenses for 2017-2018.

Many of these projects are large- percentage increase in rates is consistently below scale, span multiple years, and require substantial regional and national averages. investment. LOTT revenue needs are driven primarily by the cost of this capital construction. Of the three The Projected Budget Summary table shows cost centers shown in the chart, two – debt service anticipated expenses for each biennium over the and capital expense – exist to fund the total cost of next six years. One objective over this timeframe is capital construction. For 2017-2018, LOTT’s combined to reduce LOTT’s overall debt, which would reduce infrastructure investment (debt service plus capital costs related to interest payments and help prepare costs) represents 70% of total expense, with the utility for the possibility of new loans or bonds operating costs representing 30%. that may be needed to respond to changing regulatory requirements. Continual efforts are made to identify and implement cost-saving measures. 4

Revenue, Rates, and Fee Summary LOTT’s primary sources of revenue are the monthly service rate, known as the Wastewater Service Charge, and a new connection fee, known as the Capacity Development Charge. LOTT also receives miscellaneous revenues from other sources. Wastewater Service Charge CDC Adjustment – The fee for new connections in The Wastewater Service Charge (WSC) is used to pay 2017 will be $5,579.31, increasing from $5,354.57 most of the cost for repairs or upgrades to the existing in 2016. This reflects a 3.0% increase for inflation, in wastewater treatment system, loan payments for addition to a $64.10 increase that occurs annually system-related capital costs, and operating costs. through 2019. This separate non-inflationary The WSC is assessed based on the equivalent adjustment was put into place in 2002 to allow for residential units (ERUs). The LOTT charge is included on incremental adjustment of the CDC over nearly the customers’ utility bills, which are sent out by LOTT’s 20 years, rather than applying a major one-time partner cities. Each city also assesses a separate charge increase early on. The revenue from this adjustment on utility bills for costs associated with maintaining accounts for the cost of initial projects associated their city-owned sewer collection systems. with implementation of LOTT’s Wastewater Resource Management Plan. Because 70% of LOTT’s expenses are related to capital construction, a 3% inflationary adjustment Miscellaneous Revenue based on construction industry data was planned LOTT also earns interest on cash deposits and to apply to both the WSC and the CDC rates receives revenues from miscellaneous other sources each year of the 2013-2018 planning period.

The CDC is also assessed based on equivalent residential units. 6
Wastewater Rate Comparisons The LOTT Clean Water Alliance is frequently asked why its rates are so high. Concern about the cost of wastewater services is often expressed by residents who are comparing the cost of wastewater and drinking water services, which can appear on the same utility bill, or by new residents to the community who have moved here from areas of the country with lower utility costs. Wastewater treatment is, in LOTT is a recognized leader general, an expensive business. in wastewater treatment LOTT treats an average of 13 in the state. The Budd Inlet million gallons of wastewater Treatment Plant remains one each day. The water must be of the only treatment plants treated to high standards to employing biological nutrient meet state permit requirements removal on Puget Sound. This and be safely released into the advanced nitrogen removal environment. This requires a technology is likely to be complex system of infrastructure required of most major plants – pipelines, pump stations, along Puget Sound in the treatment plants, and related future, potentially resulting equipment – that must be up in major rate increases for and running 24 hours a day, those communities.

By contrast, drinking water system at the Martin Way services are considerably less Reclaimed Water Plant, expensive. This is due to the fact that our region which was one of the first membrane plants in the enjoys a stable supply of high quality groundwater to state producing Class A Reclaimed Water. This same meet drinking water needs. This water requires only technology is now being developed by several minimal treatment. Rates for drinking water and for communities in our region to meet ever more wastewater services can seem disproportionate, but stringent treatment requirements, and will likely are mainly due to the vast differences in the amount require significant increases to their rates. and complexity of treatment involved in each. LOTT conducts an informal survey every few years Part of the cost of wastewater treatment comes from to see how its residential rates compare with other our communities’ location along Puget Sound. The communities. Some utilities, like LOTT, use a flat rate U.S. Environmental Protection Agency (EPA) requires structure and others use a volume-based structure. To states to comply with the federal Clean Water Act even out the different structures, all of the surveyed by identifying water bodies that do not meet water rates were compared using LOTT’s basis for an quality standards and developing action plans to equivalent residential unit, which is defined bring those waters into compliance. Puget Sound, as 900 cubic feet (or 6,732 gallons) of wastewater and more specifically, Budd Inlet, are water quality per month. The current survey, conducted in 2016, impaired. The Washington Department of Ecology has shows that our monthly charges are lower than placed stringent requirements on LOTT to reduce the the average. Given LOTT’s lower than average rates, amount of nitrogen and biochemical oxygen demand and the advanced treatment already provided, (BOD) discharged into Budd Inlet. LOTT was the first, LOTT ratepayers are receiving a high value for the and until recently, the only plant along Puget Sound investments they are making. LOTT strives to ensure that was required to treat wastewater to advanced its service charges are reasonable and affordable, and secondary standards to remove additional nitrogen is meeting that objective when compared to other from the water. This high level of treatment adds utilities in the region. technological complexity and cost to the operation of LOTT’s main treatment facility. 7

Cost Allocation Operating costs are paid out of Wastewater Service LOTT is currently conducting a cost of service Charge (WSC) revenue; capital projects and debt analysis to update the basic unit of measurement, the service are paid from both WSC and Capacity equivalent residential unit (ERU), and to review the Development Charge (CDC) revenues. The allocation cost centers and cost allocations currently employed between these funds depends on the type of project in LOTT’s accounting practices.

Over time, the two funds are reviewed to ensure that system costs and new capacity costs are applied to the appropriate projects. The estimated costs and revenues are balanced over the life of the Capital Improvements Plan, and the Board of Directors reviews these costs each biennium to determine if adjustments are needed. Future Capital Improvements Plans may include projects that are demand-driven, rather than capacity-driven. 9
LOTT works to make the most of staffing levels, realigning workloads and resources to create efficiencies. Cost Control LOTT operates under a set of core values that includes managing financial resources in a responsible, sound, economical, and equitable manner. Toward that goal, LOTT actively manages projects and programs to identify efficiencies and cost-savings, minimize expenses, and limit the need to increase rates. Cost control takes vigilance and effort, and is an integral aspect of how LOTT does business. LOTT cannot prevent the rising cost of supplies and labor, but makes every effort to minimize capital and operational costs through a variety of efforts, including: • Asset Management – The Asset Management • Energy Reduction Efforts – LOTT is working Program inventories LOTT’s equipment, processes, toward a goal of 5% reduction in total energy and systems to proactively identify and schedule use by 2018, and is well on the way to meeting needed repairs and replacements. This program that goal. Through extensive work with Puget protects LOTT’s assets and extends their useful life.

Capital Improvements Planning LOTT operates under a National Pollution Discharge equipment assets that must be maintained properly Elimination System (NPDES) permit that is issued to keep the plant running. Asset management is a by the Washington State Department of Ecology proactive approach to sustaining the plant and LOTT’s for the U.S. Environmental Protection Agency (EPA). other infrastructure, allowing the utility to keep ahead LOTT must meet all permit requirements, as well as of needed maintenance and avoid unexpected, and expectations of federal and state agencies regarding potentially catastrophic, system failures. responsible utility management. The EPA has developed the Capacity, Management, Operation, and Capacity-related data is modeled in a geographic Maintenance Performance Program Plan, requiring information system (GIS) to develop population wastewater utilities to demonstrate that they have growth forecasts and predict associated wastewater a comprehensive, long-term plan for maintaining flows and loadings spatially throughout the system. existing utility infrastructure and meeting future This information is used to develop a three-part system needs. LOTT meets that expectation through Capacity Report, which helps identify and prioritize development of an organizational Performance Plan capital projects for inclusion in the Capital every six years, and through continual review and Improvements Plan.

Capital Project Categories CIP Overview and LOTT’s Capital Improvements Plan is built around Organization four major project categories. Understanding these categories, and the types of projects within them, is The Capital Improvements Plan (CIP) represents all key to understanding how they are funded. major capital projects in the foreseeable future. It is revised each biennium based on updated capacity reports, asset management evaluations, and other System Upgrades changing conditions. System Upgrade projects include improvements to existing facilities. Upgrades are necessary to replace The CIP is divided into two sections – short-term and outdated equipment, improve efficiency, and in some long-term. Each section is summarized in a table. cases, to meet higher water quality standards. One • 2017-2022 CIP – This six-year CIP groups projects of the public values guiding LOTT’s operations is to by category. It includes a Capital Budget column maximize use of existing facilities before building showing anticipated spending for 2017 and 2018 new ones.
