Avondale Water & Sanitation District: How Energy Efficiency Leadership Supports Smarter, More Sustainable Water Infrastructure

In the heart of Pueblo County, Colorado, a quiet but significant transformation has taken place at the Avondale Water & Sanitation District. This rural utility, serving residents and businesses in a community where reliable water service is essential to daily life and local economic activity, has been recognized by the Colorado Rural Water Association (CRWA) as the Energy Efficient System of the Year. The award celebrates a decade-long commitment to improving infrastructure performance, reducing energy consumption, and maintaining the high level of service that rural communities depend upon.

This achievement stands out because it was accomplished not through a single massive capital project but through steady, strategic, and well-engineered improvements implemented over time. At the center of this success is a long-term partnership between the District and Jesik Consulting & Engineering. For more than ten years, our team has provided planning, design, and implementation support that has helped Avondale navigate the complex challenges of aging infrastructure, rising energy costs, and regulatory expectations. The result is a stronger, more efficient system and a model that other rural utilities can learn from.

Energy efficiency in water infrastructure is a practical necessity for small systems balancing service reliability with financial sustainability. Avondale’s experience shows how focused engineering guidance and phased investment deliver lasting benefits. This case study explores the challenges faced, solutions implemented, outcomes achieved, and lessons for other rural water systems in Colorado and beyond. The story highlights what becomes possible when a rural utility commits to incremental, engineering-supported improvements rather than waiting for crisis-driven repairs.

Understanding the Challenges in Rural Water Systems

Rural water utilities like Avondale face conditions different from large metropolitan systems. Limited rate bases mean fewer customers share upgrade costs. Staffing is lean, with operators handling multiple roles and relying on external expertise for complex decisions. Aging infrastructure reaches end-of-life as replacement costs rise sharply, and energy prices constantly pressure budgets since pumping and treatment processes are inherently energy-intensive. Regulatory requirements add another layer of complexity, demanding consistent performance and documentation that older systems struggle to support efficiently.

For Avondale, these pressures created concrete difficulties. Pumping systems lacked modern speed control, so pumps often ran at full capacity even during lower demand periods, wasting significant energy and driving up electricity bills. Aging treatment equipment used more energy than contemporary alternatives and needed more frequent maintenance, increasing both direct costs and the risk of unexpected failures that could affect water service.

Limited automation restricted optimization. Without advanced controls, operators had fewer options to adjust schedules or respond to changing conditions, making it harder to minimize energy use or coordinate components efficiently. Over time, this led to higher lifecycle costs as isolated or deferred improvements missed integration opportunities and caused repeated interventions.

These issues affect utility finances and the communities served. Higher operating costs create pressure on water rates that residents and businesses must bear. Reliability problems can disrupt households, agricultural operations, and local businesses throughout Pueblo County. Recognizing these interconnected challenges, Avondale’s leadership chose a different path—one centered on long-term planning and energy efficiency as a practical route to cost control, improved performance, and greater long-term resilience for the entire community.

The Value of a Decade-Long Engineering Partnership

Jesik Consulting & Engineering has served as the Avondale Water & Sanitation District’s engineer for over a decade. This extended relationship has been foundational to success. Rather than project-by-project engagements, we have worked continuously with District staff to understand system evolution, anticipate needs, and develop a cohesive improvement strategy.

Long-term partnerships offer distinct advantages in rural contexts. Our engineers have accumulated detailed knowledge of Avondale’s infrastructure, history, and priorities. This reduces the learning curve for new initiatives and helps avoid impractical solutions. It facilitates better coordination across phases, ensuring improvements complement rather than conflict with each other.

A sustained partnership supports the phased capital improvement planning that proved effective for Avondale. We helped align upgrades with funding opportunities and the system’s capacity to absorb change without disrupting service. This measured pace allowed careful evaluation at each stage and refinements that improved later outcomes. The trust built over years enabled confident handling of complex challenges and maintained momentum through construction hurdles.

Pre-Improvement Conditions: Identifying Opportunities for Efficiency

Before improvements began, several issues limited performance and drove unnecessary costs:

• Pumping systems lacked variable speed control. Pumps ran at constant speeds regardless of demand, wasting energy and increasing mechanical wear.
• Aging treatment equipment used more energy and required more maintenance than modern systems, raising costs and failure risks.
• Limited automation restricted optimization. Operators relied on manual processes and fixed schedules that didn’t align well with actual needs, making dynamic response difficult.
• Higher lifecycle costs stemmed from deferred or fragmented improvements. Without an integrated plan, upgrades often addressed symptoms rather than root causes, leading to repeated interventions and missed savings opportunities.

These conditions created a cycle of elevated energy expenses, high maintenance demands, and limited capacity for growth or unexpected events. For a rural district in Pueblo County, the inefficiencies burdened both the utility budget and the community. Addressing them required technical solutions plus a strategic framework prioritizing high-impact changes and effective sequencing.

Strategic Improvements: Engineering Solutions for Energy Efficiency

Jesik Consulting & Engineering worked with Avondale to design and implement targeted improvements selected for their potential to reduce energy use, enhance reliability, and lower long-term costs. Improvements were phased to manage resources, learn from results, and maintain service. These represent industry-standard strategies adapted to this rural system’s needs.

Variable Frequency Drive Integration and Evaluation

Variable Frequency Drives (VFDs) on key pumps were among the most impactful upgrades. VFDs let pumps operate at variable speeds that match real-time system demand instead of running at full speed constantly. In water distribution, demand naturally fluctuates throughout the day and across seasons—lower at night, higher during morning and evening peaks. Matching pump output to actual need reduces the substantial energy wasted when pumps run faster than necessary. VFDs also enable softer acceleration and deceleration, which decreases mechanical stress on motors and pumps, extending equipment life and reducing future maintenance needs.

Jesik evaluated system hydraulics and demand patterns to identify the best locations and settings for VFDs, ensuring maximum benefit without compromising the ability to meet peak demands or fire flow requirements. For rural utilities with limited budgets, VFDs often deliver some of the highest returns on investment because pumping typically accounts for a large share of total energy costs, and even moderate efficiency gains translate into meaningful annual savings while improving operational flexibility.

Pump Replacement and Reconditioning

The District pursued pump replacement and reconditioning alongside VFDs. Older pumps were assessed for hydraulic efficiency. Higher-efficiency models were installed where replacement made sense; others were reconditioned to restore strong performance cost-effectively.

Improved hydraulics convert more electrical energy into useful water movement rather than losses from friction or inefficiency. Reconditioning allowed quicker efficiency gains in parts of the system while planning full replacements elsewhere. Upgrades were prioritized by energy impact and system importance.

Operational Controls Optimization

Operational controls and automation were enhanced to sustain equipment gains. Jesik helped optimize pump scheduling and system responsiveness. Modern controls enable precise multi-pump coordination, better demand anticipation, and automated adjustments that cut unnecessary runtime.

Operators can now shift pumping to efficient periods and stage pumps in their best ranges. Greater visibility supports proactive maintenance by catching issues early. For lean rural teams, these tools reduce manual effort while delivering more consistent, efficient results.

Water Treatment Plant Upgrades

Treatment plant upgrades modernized inefficient components with energy-efficient alternatives that maintain treatment quality. These lowered energy per unit of water treated and cut maintenance needs from older equipment.

Since pumping and treatment are linked, treatment efficiency gains reduced the load on pumping systems, amplifying overall benefits. Jesik ensured upgrades met regulations while advancing energy goals.

Phased Capital Improvement Planning

A phased capital improvement plan guided the work, aligning projects with funding, operational capacity, and long-term goals. Sequencing built momentum, demonstrated value, and managed risk rather than attempting everything at once.

Phased work created learning opportunities—early results informed later phases. The District could adjust based on real performance data. This engineering-led approach suits rural systems that must stretch limited resources and avoid service disruptions.

After Implementation: Tangible Improvements in Operations and Finances

Following implementation, Avondale experienced meaningful operational and financial gains. Energy consumption declined noticeably as pumps ran more efficiently and treatment processes used less power, directly lowering one of the utility’s largest and most variable operating costs.

System reliability improved with fewer unplanned maintenance events and better overall equipment performance. Operators gained enhanced control and flexibility, enabling them to manage the system more proactively and respond effectively to changing demand or conditions. Day-to-day operations became smoother, with fewer emergencies that can strain lean rural teams and disrupt service to the community.

Lifecycle costs decreased as equipment operated in more efficient ranges and experienced less wear over time. Coordinated improvements eliminated much of the previous backlog of deferred or fragmented fixes, putting the system on a stronger, more predictable trajectory. Lower operating expenses improved financial stability, giving the District greater flexibility for future planning and helping to moderate the impact of any necessary rate adjustments on Pueblo County residents and businesses.

These results emerged from steady, incremental progress over a decade rather than a single large capital project. Each phase built on the previous one, creating compounding benefits while allowing careful management of cash flow and minimizing service disruptions—essential considerations for rural utilities with limited reserves and lean operations. The Colorado Rural Water Association’s recognition of Avondale as the Energy Efficient System of the Year validates both the technical achievements and the value of the proactive, partnership-driven model, providing a replicable example for peer systems across the state.

Lessons Learned: What Other Rural Utilities Can Apply

Avondale’s experience offers practical, proven lessons for rural water systems seeking better energy efficiency and overall performance. Most rural utilities operate with lean teams and tight budgets, so every capital dollar must deliver strong, lasting value. The following principles, demonstrated in practice by the Avondale Water & Sanitation District, can help peer systems achieve meaningful returns without requiring massive upfront investment or disruptive overhauls.

Integrate Energy Efficiency into Long-Term Infrastructure Planning

Energy efficiency delivers maximum value when treated as a core planning consideration rather than an add-on. When efficiency goals shape master plans and project priorities, every investment contributes to lower operating costs. Jesik works with clients to embed these considerations early, ensuring short-term decisions support long-term efficiency and protect ratepayers over time.

Prioritize Pumping System Optimization for High Returns

Pumping systems offer some of the largest energy-saving opportunities in water utilities. VFDs, pump efficiency upgrades, and smarter controls can deliver substantial reductions with focused investment. For rural systems, this is often one of the fastest paths to measurable savings because pumps run continuously and even modest gains compound into meaningful annual dollar savings.

Embrace Incremental, Phased Improvements

Large all-at-once programs are rarely feasible for small systems. Avondale shows that steady, incremental improvements planned with engineering guidance can accumulate into major long-term gains. Phased approaches manage financial and operational risk, support learning at each stage, maintain service continuity, and align work with funding cycles. This model avoids overwhelming staff or budgets while steadily advancing the system.

Invest in Long-Term Engineering Partnerships

Sustained relationships with engineering partners are foundational. A firm that knows a system’s history, constraints, and goals provides better assessments, integrated solutions, and continuity through staff changes. Accumulated knowledge reduces missteps and incompatible projects, often yielding better outcomes at lower overall cost. For resource-limited rural districts, this partnership multiplies the effectiveness of the utility team.

These principles are demonstrated in Avondale’s real results. Other Colorado utilities can adapt them to their circumstances, using engineering expertise to pursue efficiency and reliability at a scale that fits their resources.
