▼ Traditional water supplies are reaching their sustainable limits in many areas of the United States, and throughout the world. Several water stressed areas, particularly in the Western United States, are likely to face water scarcity problems in the near future. As a result, water stressed areas are considering alternative water supplies, including wastewater and stormwater reuse, system water loss control, and demand management to ensure that ample future water can be provided. Demand management and water loss control initiatives have become more prevalent from the early 1990’s to present with 23 states now having legislative mandates for some form of demand management as opposed to 9 states in 1990. Although these initiatives are a step in the right direction, current water conservation plans are often qualitative with unreliable aggregate savings estimates, even for the most reliable indoor residential sector. Recent initiatives focused on incorporating demand management in a broader context beyond reduced water supply needs are further requiring the need to better quantify demands with higher resolution. To address these emerging needs, this dissertation presents a systematic data driven approach for evaluating parcel level water usage and demand management options for urban systems. Water usage for all water using devices is estimated using a uniform statewide property appraiser’s database combined with water utility customer billing data. Water using population is then determined with the addition of U.S. Census Block data, which is utilized to determine per capita usage rates. The potential effects of demand management are then determined directly as the difference between existing and proposed water usage after implementation. Water savings performance functions are then developed for each demand management option which are utilized to evaluate the optimal blend of demand management option. These performance functions are then utilized to evaluate the optimal blend of demand management options either to maximize net benefits or to minimize the cost of reaching a target water savings from demand management. Both linear and nonlinear formulations and solutions to these problems are presented. Additionally, explicit analytical solutions are presented based on appropriate exponential best fits of performance functions. Emphasis is placed on the residential water use sector, although generalizations to all urban water use sectors are described. Two primary case study utilities, Gainesville Regional Utilities and City of Sanford, are utilized to illustrate proposed methodologies.

▼ Unit operations (UOs) are used to manage the fate of urban rainfall-runoff particulate matter (PM) and compounds in runoff that partition to and from PM. For UOs subject to runoff loadings, computational fluid dynamics (CFD) is emerging as a design and analysis tool, albeit utilization has been primarily for time-independent flows. In contrast to the common use of steady CFD models there are few transient validated models of UOs. This dissertation aims to investigate the transient hydraulic and PM response of common runoff UOs. Utilizing a baffled hydrodynamic separator (BHS) the potential of CFD model to predict PM elution as a function of hydrograph unsteadiness is investigated. The role of mesh size (MS), time step (TS) and discretization number (DN) of particle size distribution (PSD) to simulate PM elution is examined. The impact of baffle configuration, flow rate, and hydrograph unsteadiness on hydraulic response of a rectangular clarifier (RC) is quantified through Morrill index (MI), volumetric efficiency (VE) and N-tanks-in-series (N) metrics. A stepwise steady flow CFD model is proposed and tested for transient events to predict PM separation with reduced computational overhead. The stepwise steady approach models response of a BHS and a RC to a hydrograph. The stepwise steady CFD flow model is extended to evaluate PM fate (separation and washout) in a RC and a screened HS (SHS) on annual basis. Results for BHS demonstrate MS, TS and DN significantly impact prediction of PM elution, PSDs and computational effort as influenced by the unsteadiness level. For a RC with no baffles, VE and N increase while MI decreases with flow rate. For a RC with baffles MI and N are functions of unsteadiness level and number of baffles. The stepwise steady CFD model produces effluent PM results in good agreement with measured physical model data at a significantly reduced time compared to unsteady CFD models. The coupling of a stepwise-steady CFD approach and time domain continuous simulation represents a valuable tool to estimate PM fate on annual basis. Results provide a macroscopic evaluation for finding the optimal control strategy and defining maintenance requirements to improve UO treatment.

▼ In several areas of Florida, alternative water supplies, reuse water, and water conservation are being considered as a means to ensure ample water can be provided in the future. In particular, system water loss and residential indoor usage estimates are two important aspects of water conservation programs which are currently based on simple approximations. Methods tested for estimating system water loss analyzed current water audit practices as part of a water conservation plan. One approach is to use the latest version of the American Water Works Association (AWWA) audit software, coupled with the 2009 edition of the AWWA M36 handbook, which was developed to estimate water losses. The AWWA audit and M36 handbook are useful, but different performance indicators need to be used to incorporate these procedures in water conservation plans. Water loss was then analyzed as a potential quantifiable management option in Florida, showing that Florida utilities could estimate their water losses using AWWA procedures with special attention to metering all key water use components. The AWWA software Version 4.0 includes a procedure for developing a Validity Score for the audit based on the input data quality. This scoring system is reviewed and recommendations are made for a Florida specific validity scoring system. Indoor usage methodologies for Florida were evaluated based on analyzing previous studies and test bed sites in Alachua and Hillsborough counties in Florida. Residential indoor water usage cannot be directly determined for most Florida utilities, but can be approximated based on a detailed review of end use studies that measured individual water using events. Toilets were shown to be the largest usage of indoor water in single family homes. Older homes tend to have more indoor water usage per person than newer homes due to fixture efficiency. However, newer homes use more total indoor water due to their larger size. Finally, future single family residential indoor water use patterns can be estimated based on trends in per capita water use and the expected rate at which less efficient devices will be replaced. Water utilities can accelerate this replacement rate by offering incentives to their residential customers. ( en ) Advisors/Committee Members: Heaney, James (committee chair), Koopman, Ben L.

▼ Title: Parcel-Level Methodology for Estimating Commercial, Industrial and Institutional Water Use This thesis presents a new methodology to estimate commercial, industrial, and institutional (CII) water use based on evaluation of parcel-level customer attribute and water use billing databases. The Florida Department of Revenue (FDOR) and Florida County Property Appraisers (FCPA) databases provide the heated building area and customer classifications for every CII parcel in the state of Florida. Linking this parcel-level attribute data with parcel-level water use billing data provides a major improvement in our ability to estimate CII use. Existing methods typically use the number of employees as the best single indicator of the size of the activity. Employee data is available periodically through the U.S. Census or private surveys. Census data is not available at the parcel level and survey data are expensive to collect. Evaluation of alternative measures of size that are contained in the FDOR/FCPA databases and customer billing data indicate that heated area is the best single measure of size to use across the 55 CII two-digit FDOR land use categories, or subsectors. It is relatively straightforward to link the FDOR and FCPA databases for utilities because the water management districts provide information on utility boundaries. The more difficult challenge is to link these parcel-level databases with the utility s customer billing database. The level of effort depends on the type of billing system and whether common fields are available to create the necessary relational databases. Only a few Florida water utilities are known to have merged these databases. The base case for this analysis is Hillsborough County Water Resources Services and Gainesville Regional Utilities that provide a relatively large sample of 3,205 CII parcels of which 69% are commercial, 10% are industrial, and 21% are institutional. Property and parcel attributes of this sample dataset including heated area distributions were evaluated at the subsector level and compared to the state-wide totals of CII parcels, to gain a sense of the representativeness of the sample. Then, monthly water use was analyzed to estimate average, base, seasonal, and May peak water use per CII parcel. Finally, water use coefficients expressed in gallons per square foot of heated area per day were developed for each of the available FDOR CII subsectors. Knowing the water use coefficient and the total heated area for each FDOR subsector, it is simple to estimate their total water use. The availability of the FDOR/FCPA databases provides a major improvement in our ability to estimate CII water use. The quality of these estimates will continue to improve as more utilities link their billing data with the FDOR/FCPA databases.

▼ In 2005, public water supply in Florida accounted for an average 2.5 billion gallons per day of fresh water withdrawals. A large percentage of this water is used to irrigate urban landscapes. The purpose of this study is to develop methods for estimating average and peak water use rates for outdoor water use in urban areas. These estimates are used to support the development of water conservation planning methodologies that are being developed by the Conserve Florida Water Clearinghouse. This study uses locally available and statewide available data to show how trends in home construction and in-ground irrigation have led to higher water use in single family residences (SFR) built after the mid 1980s. Irrigation water use coefficients are presented as inches of water per unit of irrigable area for three classes of users: accounts with in-ground irrigation systems that are reported to the property appraiser, accounts without sprinklers, and accounts with separate irrigation meters. Additionally, SFR accounts that substitute potable water with alternative sources was estimated for the study area. The Alachua County Property Appraiser s database was used to extract detailed information on irrigable area, impervious area, pervious area, and the presence of in-ground irrigation in each SFR parcel. This information was used in conjunction with a novel, k-means clustering, approach for hydrograph separation of indoor base and seasonal irrigation water flow, based on the peak and average of single metered monthly billing records from October 2007 to September 2008. The disaggregated irrigation use was then compared using property appraiser groupings denoting in-ground irrigation and year built. A k-means clustering algorithm was used to determine whether irrigators use potable water or irrigate with a substitute water source. An application rate was calculated for the accounts that use the potable system to irrigate. Results for Alachua County confirm previous studies, which show that indoor water use can be estimated as a steady state rate with an average daily flow of 65 gallons per person per day. Additionally, irrigation is a variable rate with an average peak month use of 684 gallons per day per account and an annual average use of 320 gallons per day per account from October 2007 to September 2008, for the subset of customers that irrigate. The median irrigable area for homes using the potable system for irrigation was 10,383 square feet. Thus, the expected water use coefficients, for the Gainesville observations, are: an annual average of 1.5 inches per month per square foot of irrigable area and a peak rate of 3.1 inches per month per square foot of irrigable area. The occurrence of in-ground sprinkler systems in new homes has increased from 10% of homes in the mid 1980 s to 80% of homes built in 2007. In-ground irrigation homes make up 27% of the cumulative housing stock as of 2007. This cumulative percentage is expected to increase if the popularity of in-ground irrigation remains at current levels.

▼ This dissertation includes both theoretical and empirical research in economic efficiency. The first chapter theoretically evaluates how to design procurement models when two agents may have better information than the principal about their production costs and about the similarity (i.e., correlation) of those costs between agents. The results indicate that if the uncertainty about the correlation is not severe, the principal should design a contract as if she knew that correlation is the lowest possible. The drawback with such mechanism is that the high-cost agent earns rent if correlation is high. In contrast, if the uncertainty about the correlation is more severe, the principal should not tailor the solution to any of the potential correlations. This contract reduces the rent of the high-cost agent if correlation is high by giving rent to the low-cost agent if correlation is low. Although the welfare level may be different, the characterization of the results holds when both agents observe the correlation and do not report it, as well as in the case where only one agent observes and reports the correlation to the principal. Finally, when the probability of the low-correlation setting is very small, the principal may find optimal to exclude the high-cost agent from the contract if correlation is low, allowing her to achieve the socially optimal situation if correlation is high. The second chapter empirically evaluates the relative efficiency of different type of water and sewerage operators in Brazil. The analysis consists of a cost comparison between public and private operators, and between state-level and municipal-level operators. In a first stage, a cost function is estimated utilizing a fixed-effects panel data model. In a second-stage, the firm-specific costs from the first stage are explained by means of firm-type indicator variables. The results illustrate that water and sewerage provision in Brazil is characterized by substantial economies of scale, indicating that state-level provision is economically more efficient. The results also show that there is not an economically significant difference between the costs of private and public firms.

▼ The research presented here addressed two aspects of stormwater prevention. The first aspect was the elimination of stormwater through retention basins. Infiltration rates were measured by Double Ring Infiltrometer (DRI) within 40 basins in Alachua, Leon, and Marion counties. Measured rates were compared to designed rates to determine whether basins were operating as designed. The 40 basins were equally divided between residential and Florida Department of Transportation land uses. Texture analysis was also performed on soil samples taken from each infiltration location; soil types ranged from sand to sandy clays. Eleven of the 40 basins were also instrumented with monitoring equipment to measure drawdown rates. Three basins did not adequately store water to determine drawdown rates. However, 6 of the remaining 8 basins had drawdown rates less than DRI rates while the other 2 basins were not statistically different from DRI rates. This indicated that subsurface conditions were controlling basin drawdown rates. DRI rates frequently varied by at least an order of magnitude within basins. Based on DRI rates, 16 (40%) basins had rates less than their designed rates, 10 (25%) had rates equal to their designed rates, and 14 (35%) basins had rates greater than their designed rates. Additionally, FDOT basins had a higher proportion of basins with greater DRI rates than residential basins and coarser basins were also more likely to have DRI rates greater than designs. Greater size and diversity of vegetation resulting from less frequent maintenance in FDOT basins may have resulted in a higher proportion of sites with rates equal to or greater than designs. The second aspect is stormwater generation. Traffic during construction has been shown to compact soils, resulting in reduced porosity and infiltration rates and increased runoff. In agricultural settings soil amendments have been found to counteract compaction effects. Two soil amendments (compost and fly ash) were evaluated for mitigating compacted soils. Forty-two lysimeters were filled with two soils (Orangeburg Sandy Loam and Arredondo Fine Sand) overlaying a drainage layer of quartz stone. Runoff was directed into collection tanks and volumes were recorded. The soils were compacted to levels representative of observed levels found in North Central Florida based on bulk densities and infiltration rates. Runoff and leachate samples were analyzed for nitrogen species and orthophosphorus. Incorporating fly ash did not significantly reduce runoff. Tillage to at least 10 cm decreased runoff compared to compacted soils. However, adding compost treatments did not significantly reduced runoff compared to just tillage.
