Padre Dam Projects
Capital Improvement Program
Padre Dam’s Capital Improvement Program (CIP) ensures we have a plan to maintain, upgrade, and replace the District’s infrastructure. The CIP helps enhance the overall quality of life by improving the infrastructure and facilities that provide reliable services to our rate payers. Below you will find information on projects we are currently working on and the projects we have planned for the future.
Recently Completed Projects
- Advanced Water Purification Demonstration Project

- Comprehensive Facilities Master Plan
- East County Advanced Water Purification Program - Planning Study
- Influent Pump Station Grinder Replacement
- Pump Station No. 1 Surge Tanks Replacement
- Eastern Service Area Secondary Connection Project – Initial Site Grading
- 2015 Urban Water Management Plan
Mast Boulevard Bridge and Prospect Avenue Bridge Pipeline Repair Project
This project consists of pipeline repair and replacement at the Mast Boulevard and Prospect Avenue bridge locations (Santee) to improve operations. This work is important to ensuring the reliability of our water service.
Eastern Service Are Secondary Connection ProjectThis Project consists of a potable water pump station capable of supplying 9 million gallons of potable water to the District’s Eastern Service Area, a 1.75 million gallon forebay reservoir, a San Diego County Water Authority (SDCWA) flow control facility, and approximately 6,800 linear feet of 20-inch diameter welded steel pipe, and associated appurtenances. This project will assist the District in achieving its strategic goals by increasing water supply and ensuring greater water reliability.
This project consists of various upgrades to the District’s existing sewer collection system including trunk sewer repair and replacement, diversion structure replacement, lift station piping repairs, and manhole installation.
Interstate 8 Crossing at Viewside LaneThe District maintains and operates an existing 8-inch water main under Interstate 8 at Viewside Lane to provide potable water and fire service to a residential area consisting of six homes off of Viewside Lane near Alpine, California. The project includes the replacement of the existing 8-inch HDPE pipeline that crosses under I-8. The existing pipeline is installed within a 16-inch steel casing. The existing pipeline will be removed and a new 8-inch steel pipe will be installed.
El Capitan Pipeline Valve & Vault Removal
This project consists of removing an existing 30-inch valve along the District’s 36-inch diameter El Capitan pipeline.
Advanced Water Purification Project
In its entirety, the proposed project will provide planning, design, and construction of a 0.1
(100,000 gallons per day) purifying plant using Microfiltration/Reverse Osmosis (MF/RO) technology at the WRF. The MF/RO technology is the process currently proposed to produce Advanced Water Treatment water for the Phase 1 expansion of the WRF from 2.0 mgd to 4.4 mgd and would use water produced from tertiary filters or effluent from the chlorine contact chamber.
East County Advanced Water Purification Program – Feasibility Study
This Feasibility Study is the next step in the implementation of the East County Advanced Water Purification Program. The primary objective of this study is to advance the preferred alternative identified in the Planning Study in three areas to ensure feasibility: 1) financial feasibility and ratepayer affordability, 2) environmental and regulatory compliance, and 3) public outreach. Scope of work for the first year of the Feasibility Study includes engineering studies, pre-design documents, environmental assistance, geotechnical & surveying, permitting and regulatory coordination, financial management assistance, and community and stakeholder outreach support.
Brine Minimization StudyPadre Dam has been evaluating brine minimization technologies to reduce the brine disposal cost and increase water supply production in the reverse osmosis (RO) process for our Advanced Water Purification Project. A $200,000 grant was obtained from the Bureau of Reclamation’s (BOR) Desalination and Water Purification Research and Development Program to pilot test two brine reduction technologies, namely a conventional brine reduction process via third stage recovery RO (RRO) and a closed-circuit desalination (CCD) process developed by Desalitech Corporation (Desalitech).
Free Chlorine and UV/AOP Challenge TestingThis study is intended to build off the Advanced Water Purification Demonstration testing findings and further the understanding of the free chlorine disinfection and UV/AOP processes necessary for design. Testing will provide clarity on the design specifications for the expansion of the Ray Stoyer Water Recycling Facility (WRF) and the full-scale design of the Advanced Water Purification Project.
2015 Comprehensive Facilities Master Plan - Program Environmental Impact Report (PEIR)
In addition to compliance with the California Environmental Quality Act (CEQA), development of the PEIR for the District's Master Plan will (1) provide a more comprehensive consideration of potential environmental effects, including cumulative impacts, mitigation measures, and alternatives, than would be provided for individual projects; (2) provide legal defensibility by ensuring that consideration of cumulative impacts avoids "piece-mealing"; and (3) allow the District to consider broad policy alternatives and programmatic mitigation measures at an early stage when it has greater flexibility to deal with potential issues.
Pipeline at Bridge Crossings – Technical AssessmentThe District operates and maintains a network of pipelines supporting the potable water system. Due to geographical challenges, some of these pipelines have been constructed within or hung on various bridges. There are 19 such bridge crossings throughout the system with pipeline diameters range from 8-inches to 24-inches. The purpose of the assessment is to perform an overall structural and seismic condition assessment of the existing pipelines located at these bridge crossings and provide a report assessing the installation, identifying potential improvement projects, estimating the construction costs, and prioritizing the projects.
Projects on the Horizon
Pipeline Risk PrioritizationThis technical study will develop a prioritization of the District’s potable water pipelines for condition assessment. It is anticipated that a GIS based risk model will be developed to evaluate the likelihood and consequence of failure of the water infrastructure and ultimately assist in prioritizing where condition assessment activities should begin.
Pump Station Surge Tanks ReplacementThis project will involve the replacement of up to 4 existing pump station surge tanks that have been found to have corrosion on the internal surfaces.
