The following major system maintenance and replacement projects and Capital Improvement Projects (CIPs) have been completed since 2005.

  • Well No. 17

Well 17 was drilled and completed in 2007. Due to delays obtaining a permit to operate the well from the Office of the State Engineer, EAWSD began producing from the well on a permanent basis in 2010.

  • Well No. 18

Well 18 was drilled and completed in 2010. Due to delays obtaining a permit to operate the well from the Office of the State Engineer, EAWSD began producing from the well on a permanent basis in 2012.

  • Old Road Ranch Booster Pump Station and Waterlines

This project replaced approximately 8,000 feet of undersized existing pipes with larger pipes and added approximately 600 feet of new pipe to improve fire protection on North Chamisa Drive and on Sierra Del Sol.  It also replaced the Old Road Booster Pump Station to improve fire protection and pressures to areas east of Hwy 285 near Old Road and Ranch Road.

  • SCADA System Improvements

A Supervisory Control and Data Acquisition (SCADA) system allows a water system operator, at a single central location, to monitor and control equipment at locations throughout the water system.  A central control room computer workstation is used to communicate, often via radio, with intelligent process controllers located at many widely distributed sites.  The process controllers each monitor local instrumentation and provide alarms and measurement information to the control room operator.  System operating data can be sent from remote sites to the control room where an operator can quickly and easily assess the safety and efficiency of system operations.  Set-point changes and control requests (e.g., open/close valves or start/stop pumps) can be sent from the control room to the process controllers, making it unnecessary for an operator to attend or routinely visit remote locations.


The District’s SCADA system was seriously outdated, consisting of costly proprietary components, and lacking redundancy.  The District conducted a SCADA system condition and needs assessment report in 2008 and a SCADA upgrades implementation plan in March 2011.  Both of these reports identified serious deficiencies that required upgrade in order to improve operations efficiency, reduce operating costs, provide redundancy, and mitigate risk.  This project upgraded the District’s SCADA system based on the recommendations from its SCADA assessment studies on the basis of priorities identified in those studies.  The benefits of the project were to significantly improve the utility’s operating efficiency, to improve the safety and security of utility operations, to improve system-wide monitoring and reporting capabilities, to reduce labor-intensive field visit requirements, and to improve planned maintenance capabilities and be more reactive to unplanned events.

  • Torreon Booster Pump Station

The Torreon Booster Station has been a critical part of the District’s infrastructure since the commissioning of Well 17 in 2010.  This project replaced the existing pumping station to accomplish the following: (1) add a second pump (one operating, one standby) for redundancy, (2) install the pump station in an above-ground enclosure to protect it from flooding and to enable maintenance of the station without confined space entry, and (3) replace the electrical components which were prone to single contingency failure.  A connection port for the District’s standby generator was also added to enable operation in the event of a significant power outage.  The Torreon Booster Station is a critical asset to the District’s water system, serving over 75% of customers.  The facility was upgraded to help meet peak demand and to provide redundancy for the District’s ability to move water from its most productive wells to the most heavily used higher pressure zones.

  • Well No. 2 Redrill and Replacement

This project replaced EAWSD Well No. 2 with a new well adjacent to the existing well, allowing for construction of a slightly deeper well completed with a screen set lower into the formation.  The lower screen prevents cascading of water down the inside of the well casing,  a situation that increases maintenance and reduces production from a well. Cascading in the old well caused sand to enter the casing, leading to pump wear and erosion of the formation outside the well casing, reducing water quality and production from the aquifer. While it was hoped that the replacement well would have greater production capacity than the old well, the new well production is 70 gpm, the same as the well it replaced.

  • Chemical Storage Building

This project purchased and installed a 96 SF pre-fabricated, purpose-built storage building for storage of water chlorination chemicals (Sodium Hypochlorite drums).  The building meets all OSHA and other federal and state codes for storage of hazardous materials.   It was fabricated using non-corrosive building materials and includes spill containment features to prevent environmental damage should a spill occur, exhaust and ventilation equipment, specific electrical needs, and site placement on a stable concrete foundation to ensure the safety of the employees that handle and transport the hazardous chemicals in and out of the storage building.

  • Pressure Zone Optimization -  Phase 1

 The EAWSD Pressure Zone Optimization Project will design and construct improvements to the EAWSD water system to reduce system pressures, water loss and use and to help evenly distribute storage requirements among existing tanks.  Many of the existing main lines currently experience pressures above 100 psi, which increases waterline breaks, reduces the service life of waterlines and other system components, and increases the frequency of pipe and valve failure.  High pressures also lead to increased water loss and customer use, since higher system pressures result in higher velocities and flows within pipes.  Higher pressures can cause water pipes to expand slightly, increasing the size of cracks in the pipes and gaskets, allowing for additional water loss.  Reducing pressures will increase the service life of existing system assets and reduce demand on water production wells due to reduced system water loss and customer use. Another major objective of this project is to redistribute and reduce water demand from pressure zones with limited storage capacity to pressure zones with adequate storage capacity to maintain fire and emergency storage as system demands increase.  Additional growth or increase in water demand in two EAWSD pressure zones could currently compromise the District's ability to maintain adequate water storage for fire protection. The project will ensure that all areas affected will meet fire codes for fire flow and pressure with adequate storage for emergencies equal to 2 days of average daily use plus fire flow for 4 hours. This project is being phased on the basis of priorities described in the EAWSD Pressure Zone Optimization Study, June 2014. Phase 1 consisted of implementing 7 of the 20 recommendations (Nos. 1, 2, 3, 4, 11, 14 and 15).
