Capital Improvement Program

The Capital Improvement Program (CIP) is a planning and budgeting tool that provides information about SAWS' infrastructure needs.It identifies requirements for sustaining, restoring and modernizing the facilities and infrastructure that support water supply and delivery, wastewater collection and treatment, and chilled water requirements in the SAWS service area. It also prioritizes and schedules the projects for funding and implementation through a multi-year plan.

The CIP supports four core business areas: chilled water, water delivery, wastewater and water resources. The 2016 program totals $247 million.

Core Business Area Approximate Funding
Chilled Water $4,903,375
Water Delivery $83,478,291
Wastewater $129,552,502
Water Supply $29,140,512

The Chilled Water Program is self-funded through revenues it generates from customers. The Water Supply Program, which includes the development of long-term water supplies from surface and alternative groundwater sources, is funded through the water supply fee. The Water Delivery/Wastewater CIP includes projects that expand, improve and replace infrastructure required to generate, deliver, collect and treat water and wastewater and is funded through bonds, revenues and impact fees.

The 2016 Wastewater program continues an expanded Sanitary Sewer Improvements program to reduce sanitary sewer overflows through visual inspection, cleaning, and repairing or replacing aging and defective sewer mains. In addition, SAWS will upsize sewer mains in need of increased capacity and rehabilitate or eliminate lift stations that contribute to sanitary sewer overflow. For the 2016 wastewater program, $92.6 million is budgeted specifically for the Sanitary Sewer Improvements Program. SAWS will construct a new $20 million sewer main in the Western sewershed between Boerne Stage Rd. and Fredericksburg Rd. that will eliminate lift stations and reduce the risk of sanitary sewer overflows, as well as supporting growth in the area. The Wastewater program includes $22.9 million for governmental projects that support City of San Antonio, Bexar County, and TXDOT street, highway, and drainage improvements, and $4.7 million to begin design of improvements to the Dos Rios Water Recycling Center.

The 2016 Water Delivery program includes rehabilitation of a 1950's era pump station, design of a project to replace chlorine tanks with sodium hypochlorite disinfection system to improve safety in populated areas, and projects to improve automated pump station control systems. Other projects will focus on reducing water loss in water mains and connecting Joint Base San Antonio to SAWS system. The District Special Project (former Bexar Met Water District) program includes design of a new pump station, two pump station improvement projects, replacing an aging ground storage tank, and improving water pressure in a neighborhood in South Bexar County. The Water Delivery program includes $29.3 million for governmental projects that support City of San Antonio, Bexar County, and TXDOT street, highway, and drainage improvements. The total SAWS Water Delivery program totals $72.1 million and the DSP program totals $11.5 million, for a total of $83.5 million.

The 2016 Water Supply program includes $28.5 million to begin design and land acquisition for integrating 50,000 acre-feet of new water supplies from the Vista Ridge pipeline into the SAWS distribution system.

The overall funding split for the 2016 water production and delivery and the wastewater collection and treatment program is 93% repairs and replacements and 7% additional capacity to support new growth and development.

The 2016 program was developed using a refined prioritization process started in 2006. Projects generated by the CIP stakeholder groups from SAWS Treatment, Production, Master Planning, Facilities Engineering, Operations, and Distribution and Collection departments were reviewed and scored by a CIP Planning Group consisting of submitting vice presidents, directors and managers. The scoring process addressed the business risk exposure, independent of available funds, through a derivative of the Failure Modes and Effects Analysis (FMEA) methodology. FMEA provides a structured approach to the analysis of risk through a composite index that considers potential impact of failure, probability of occurrence, and ability to mitigate the impact. Projects were totaled by dollar amount and compared to the long term funding strategy. The CIP projects were developed using 2015 cost estimates, and SAWS overhead and an inflation factor of 2.8% per year were added to develop the programmed costs for 2016 and future years. The 2016 and 5-year CIP project lists were reviewed in detail by an executive CIP review committee. Projects were totaled by dollar amount and compared to the long term funding strategy and final selection was made by SAWS Executive Management Team and approved by SAWS Board of Trustees.

Please note that the Capital Improvement Program project list is subject to change due to funding, project needs, and emergencies.
