The San Antonio Water System's (SAWS') C-13 - Broadway Corridor Wastewater project is an important step in SAWS' implementation of its Wastewater Master Plan created to reduce overflows throughout the system. The project is located in SAWS' Central Sewershed, which collects wastewater from the central area of San Antonio (including downtown) and transfers it to the Dos Rios Water Recycling Center (WRC). Six unique alignment alternatives were developed. Each of the alternatives was compared against a set of criteria to determine the most preferable option. These criteria included: cost; constructability; permitting concerns; utility coordination; environmental concerns; cultural resources sensitivity; and impact to local businesses, construction conflicts, traffic control, and pavement repair. A combination of rehabilitation and new construction was determined to best meet the project criteria. To aid in the optimization, a hydraulic model using InfoWorks CS (version 10.0) was developed for the project. A total of eight InfoWorks model networks were created and evaluated. By performing the alternatives evaluation and developing the InfoWorks model, the project team was able to reduce the cost of the sewer improvements from the original conceptual cost of $46M to the current estimated cost of $26.5M. Additionally, this combination of new construction and rehabilitation of existing lines greatly reduces potential disturbances to the historical and central business districts of downtown San Antonio. © 2013 American Society of Civil Engineers.

When you prepare the Thanksgiving meal, do you ask each person to make a dish of their choosing, with no coordination for an overall cohesive meal? Probably not. Most likely, you plan, because you want everything to fit together. Now imagine a water utility with different departments like water quality, finance, and administration. Most water utilities have high energy costs, so each department needs to manage and reduce its energy use – but typically there’s no plan to synchronize these efforts. With such a piecemeal approach, the utility may get overall energy savings, but it’s not maximizing the potential to meet ambitious efficiency goals or reduce power costs. Enter the Energy Management Plan (EMP), a tool that sets up an organization-wide strategy for energy use. By creating a coordinated vision, an EMP establishes clear efficiency goals and gives departments the flexibility and direction for meeting them. That’s what this summer’s EDF Climate Corps fellow focused on at Tarrant Regional Water District (TRWD), which supplies water to 2 million users in the Fort Worth area. The TRWD fellow found opportunities where an EMP could improve the utility’s energy efficiency and management, leading to potential savings and less wasted water. Energy is a high cost for water utilities. It takes a lot of electricity to treat and distribute water, on top of fueling the offices and facilities. In many cities, water-related energy costs can be 30 to 40 percent of their total energy bill. With energy efficiency alone, those costs could be lowered by 15 to 30 percent – representing thousands of dollars. Installing low-water clean energy like solar or wind at a water utility could further bring down electricity costs. But these initiatives aren’t going to start themselves. That’s where an EMP comes in. Basically serving as a road map, an EMP gets all departments working toward the same goal: reducing energy use and costs. It also helps prioritize the most cost-effective projects, such as targeting a high-energy pumping station for equipment upgrades or establishing leak-detection programs to reduce wasted water (and associated wasted energy). Further, when water utilities identify high-energy-use pain points in their systems, it could potentially lead to partnerships with electric utilities, which might even help pay for major energy efficiency projects. As opposed to most water utilities, many electric utilities already have energy efficiency programs and funds dedicated to meeting those goals. But if an electric utility has been offering efficiency programs for years, it may have exhausted the low-hanging fruit and need to explore new options, such as efficiency through water conservation. By pairing up, both the water and electric utilities could maximize available efficiency and water conservation funds, helping each side reduce its energy use. California is a pioneer in this type of partnership. Improving energy efficiency can not only lower costs and save energy, but save water too. That’s because many of the resources we currently use to make energy – like coal and natural gas – require a significant amount of water. The U.S., for instance, gets nearly 90 percent of its power from fossil fuel-fired and nuclear power, which accounts for nearly half of the country’s total water withdrawals. Therefore, cutting energy use indirectly cuts water use. With a changing climate, many cities and areas will face increased water stress that could put additional pressure on electric systems. Plus, as the population grows, demand for water and electricity increases. Finding opportunities to protect water supplies – like through energy and water efficiency – will be critical. TRWD operates more than 150 water facilities, and most of the energy it uses is for moving water from East Texas. The utility is committed to lowering energy costs – currently there are about a dozen different programs aimed at doing so. Our EDF Climate Corps fellow’s main mission this summer was to develop a plan to streamline operations and consolidate TRWD’s energy achievements and goals into a cohesive energy management plan. These recommendations can help TRWD improve overall operational and energy efficiency, and they exemplify what EDF Climate Corps does best: find ambitious yet achievable goals to reduce energy use and expand clean energy deployment. Future iterations of an EMP could include increased use of self-generation clean energy (e.g. solar panels) to further reduce TRWD’s energy demand. In fact, this summer, another EDF Climate Corps’ fellow for San Antonio Water System (SAWS) – San Antonio’s municipally-owned water utility – not only identified energy-efficiency savings for the utility, but also evaluated the feasibility of onsite solar generation, of which SAWS is already a national leader. No one wants a Thanksgiving meal of only side dishes. But that imbalance is what many water utilities currently are working with: They may have some sort of process to reduce energy use, but lack a comprehensive utility-wide energy agenda. Rolling small or piecemeal programs into a larger EMP could increase operational efficiency, lowering costs while saving water and energy. Texas is a great example of a state with water utilities ready to embrace the rewards of cohesive energy plans, and we look forward to seeing progress over the coming years.

The San Antonio Water System's (SAWS) Brackish Groundwater Desalination Program is designed as part of a strategy to meet San Antonio's water needs over the next 50 years while reducing dependency on more vulnerable water sources. The Texas Water Development Board has confirmed that a vast supply of brackish groundwater, more than 300 million acre-feet, exists in our region and has yet to be fully developed. According to the 2012 State Water Plan, which examines Texas' projected water demands and resources through 2060, 3.5 percent of the new water supplies to be developed by 2060 will be provided by desalination.1 SAWS has elected to employ reverse osmosis (RO) membrane technology for desalination of brackish groundwater from the Wilcox Aquifer in South Bexar County, Texas. The Texas Commission on Environmental Quality (TCEQ) requires that all membranes be approved for use for each specific water source by providing historical qualification or pilot testing. SAWS began performing pilot testing in 2008 to confirm the performance of membranes from three different membrane manufacturers and, therefore, provide procurement and operational flexibility for the full scale desalination facility. A consultant performed demonstration scale testing on one manufacturer's membrane and SAWS performed testing on the other two with in-house staff. SAWS primary goals in the pilot testing effort were to obtain a TCEQ capacity rating and approval of the use of membranes from three manufacturers for the full scale facility and to evaluate certain pre-membrane processes. However, SAWS derived additional benefits from the piloting work. Analysis of the pilot testing results enabled SAWS to form some conclusions towards performance variances among manufacturers. The pilot study also produced unanticipated results in the clean-in-place performance on the membranes of two manufacturers that merited additional testing and scrutiny. © 2013 American Water Works Association.

The San Antonio Water System (SAWS) serves more than 1.6 million people and more than 465,000 water customers in the greater San Antonio area and surrounding counties. Over the last several decades San Antonio has experienced rapid population growth, the integration of the Bexar Metropolitan Water District, regulatory withdrawal limitations, and increasing drought restrictions that have put a strain on the Edwards Aquifer, San Antonio's primary water supply. SAWS has been working to meet the increased water demand through a strategy of conservation, reuse, and investments in new water supply resources. The Regional Carrizo Program (RCP) is a water supply project that was developed through a cooperative regional partnership with the Gonzales County Underground Water Conservation District, the Schertz-Seguin Local Government Corporation (SSLGC), and the Gonzales County Water Supply Corporation. Through this unique partnership, the project will convey up to 12,688 acre-ft of Carrizo Aquifer groundwater to Bexar County, which represents the largest non-Edwards water supply in SAWS' history. This paper will focus on the planning, design, and construction for one of the most challenging components of the RCP: fast-track design and construction of the 11.5 mile, 36-in. diameter water delivery pipeline (WDP). The WDP will transmit water beginning in the City of Schertz and traverse through three counties and four cities, terminating at an existing SAWS pump station on the northeast side of San Antonio. Challenges faced during the planning phase included route selection through urban residential and industrial areas, future road expansions, drainage channels, new land developments, and numerous utilities. Unique design elements included provisions for construction of a pipeline within drainage channels; acquisition of easements from more than 60 landowners; and multilevel coordination with counties, cities, state agencies, and utility owners. Construction challenges included urban construction, extensive bore/tunnel crossings, two interstate highway crossings, railroad crossing, unforeseen utility conflicts, new development, a major creek crossing, expedited submittal reviews, coordination of pipeline tie-ins and testing, interior inspection of 11.5 miles of 36-in. steel pipeline, and oversight of multiple installation crews to meet the program schedule. © 2014 American Society of Civil Engineers.

Over the last several decades, San Antonio has experienced rapid population growth. The San Antonio Water System (SAWS) currently serves more than 1.6 million people in Bexar County Texas as well as parts of Medina and Atascosa Counties, and has over 460,000 water customers. With the integration of the Bexar Metropolitan Water District, regulatory withdrawal limitations, and increasing drought restrictions that have put a strain on the Edwards Aquifer, SAWS has had to increase its water supply and system flexibility. SAWS has been working to meet the increased water demand through a strategy of conservation, reuse, and investments in new water supply resources, and will increase system flexibility with the Water Resources Integration Plan (WRIP). Currently, the Twin Oaks Aquifer Storage and Recovery (ASR) facility in South Bexar County allows SAWS to store excess Edwards Aquifer water from the east side of San Antonio. That water can then be recovered from the ASR during periods of high demand, significantly increasing SAWS operational flexibility. The ASR Pipeline, completed in 2004, is currently the only conduit between the ASR and SAWS' distribution system; moving water into the distribution system during production mode and reversing flow to inject water into the ASR well field in recharge mode. Since future water supply facilities will produce a constant base flow, additional flexibility is needed for continued recharge of the ASR. The WRIP will provide that flexibility. The WRIP consists of approximately 45 miles of 48" to 60" diameter steel pipe and two associated pump stations, extending from the ASR to west San Antonio. The WRIP will be constructed in two phases and will ultimately convey up to 75 MGD of potable water from four different sources: treated water from the Brackish Groundwater Desalination Facility (Wilcox Aquifer), Local and Expanded Carrizo Wells (Carrizo Aquifer), and recovered ASR water (Edwards Aquifer). Similar to the ASR pipeline, the WRIP pipeline will also be used to recharge the ASR well field using reverse gravity flow. The WRIP pipeline will work in tandem with the ASR pipeline to offer operational flexibility and provide water where San Antonio needs it most. This paper will describe the WRIP and specifically discuss design concepts that allow the WRIP to give SAWS additional flexibility in managing their water supply. © 2015 ASCE.

Water scarcity, climate change, population growth and rising infrastructure costs have opened the door for unconventional or ‘new’ water sources. Reclaimed water reuse has historically been practised for potable use in the United States as de facto water reuse or unplanned indirect water reuse. The increasing number of planned indirect water reuse projects in the country and the approval of the first direct potable reuse projects have exposed the limitations of the regulatory system at the national and state levels. These limitations pose barriers and/or add uncertainty to the viability of potable water reuse. © 2016 Taylor & Francis

A strategy of long-term planning, conservation, and diversification of supply sources, including recycled water delivered programmatically is helping the San Antonio Water System (SAWS) to satisfy the area's thirst for safe drinking water in a state blessed by sunshine and natural gas but plagued by drought. Construction of the Twin Oaks Brackish Groundwater Desalination (BGD) Program will help SAWS further diversify the utility's water portfolio. Facilities will also be built to support operations, laboratory, public interaction, and research functions. The conceptual design for the BGD program includes the implementation of a new, 30-mgd brackish groundwater supply to be constructed in three phases, with the initial 12-mgd capacity commissioned by October 2016.
