Water Plant Corruption Case
How It Started


Unraveling Weslaco’s Troubles: The Scheme Leading to the Water Plant Bribery Scheme.

Nestled in the heart of Weslaco, Texas, a compelling finding unfolds—one that peels back the layers of mismanagement and alleged financial misconduct while shedding light on a community's battle to mend its strained water plant and sewer system.

In April 2019, the Texas district court indicted John F. Cuellar, Taffolla and some other prominent figures in Weslaco for a bribery case that transpired during the Weslaco Water and Sewage Treatment Plant construction.

How it all unveiled

In 2004, the city of Weslaco's water shortage issues became more dominant and beyond control, ranging from the below-capacity water treatment plant to the inadequate wastewater treatment facility.

The city commission sought methods to fix this long overdue project, ranging from loan requests to sales of the city bonds, which were sold in 2007


The Star Player Emerges: Enter Adrian Gonzalez

Newly elected commissioner Adrian Gonzalez, having taken his oath on May 18, 2006, emerged as a pivotal figure whose choices would have a crucial impact in shaping the water treatment bribery case.

Gonzalez's early interactions hinted at the plot taking place. Notably seconding the motion that propelled J. Cuellar into the role of mayor pro-tem, suggesting a possible convergence of ideologies or shared goals between the two. This alignment would later become a force to recon

A consistent voting pattern between Gonzalez and Cuellar hinted at a more profound connection or alliance extending beyond formal commission meetings' confines.

Navigating Complexity: Unveiling Accounting Errors and Strategic Pivots

During planning and preparation to solve the various events clouding the city of Weslaco. There was a need for presentations and reports to be provided by the city manager, city secretary, and financial advisor. This revealed conflicting and inflated material prices and doctored accounting and technical errors.

Tensions soared as the mayor critiqued the quality of information presented, highlighting the discrepancies between reports furnished by the city manager and the financial advisor. The mayor's call for tallying accounts laid bare the escalating concerns regarding the accuracy and reliability of the data presented.

But this was swiftly redirected by the dynamic duo of Commissioner Ardian and Mayor Pro-Term Cuellar. Gonzalez and Cuellar's calculated endeavors to turn the commission's focus unveiled a tactical approach to maintain a united front.

Navigating Murky Waters: Unraveling CDM's Influence and Ambiguous Management

As planning commenced for the outlined projects that would be funded using the 2007 bond, there was a suggestion from the city manager to recruit a project manager to oversee the projects, as this was deemed a practical course of action.


The city manager recommended Camp Dresser McKee (CDM), the same firm responsible for the Rio Grande Water plant, and motions were swiftly moved and seconded by Adrian and Cuellar to make CDM the overseeing firm.

The CDM’s first course of action was to award themselves the two most significant projects in the 2007 bond, totaling more than half of the 2007 bonds. The fact raised eyebrows in the city commission but was quickly silenced by a motion from Adrian, which, as you guessed, was seconded by mayor pro-Tem J. Cuellar.

The commission's reliance on CDM orchestrated by Adrian and Cuellar raised eyebrows. What initially seemed like CDM's mandate to manage other engineering firms took a twist, with CDM securing the lion's share of the budget. This revelation came to light when critical documentation regarding procuring engineering services overseen by CDM remained conspicuously absent, casting a cloud of uncertainty over their involvement.

The CDM charges were excessive, and complaints were made by Mayor de la Rosa, who expressed reservations about the fees quoted by these firms. The mayor was highly concerned about the ineffective use of taxpayer money and continuously spoke against it but was quickly brushed off by suggestions from the city manager, followed by motions from Adrian and Cuellar.

Untangling a Web of Choices: Probing CDM's Unsettling Path

As the intricate narrative of Weslaco's water project continued to unfold, March 2008 emerged as a pivotal moment that cast the spotlight squarely on CDM.  Adrian Gonzalez and Mayor Pro-Tem Cuellar took center stage with particularly calculated roles in this crucial juncture. Cuellar spearheaded the motion to bestow the contract upon CDM, while Adrian seconded the motion.

However, doubt hovered over this proposition, considering CDM's proposed charges far exceeded the conventional 6% - 9% range the city had typically abided by. This deviation from the norm marked a departure, presenting amounts nearly double what was historically bid for similar endeavors.

The suspicion that CDM deliberately inflated the engineering services fees for personal gain began to take root, and the selection process was scrutinized. The revelation that CDM had chosen various firms, including themselves, triggered a wave of skepticism. The fact that CDM designated itself for the most substantial projects, constituting a significant sum, seemed to cross ethical boundaries.

Amid Concerns: Mayor de la Rosa and Citizen Vaughan Raise Alarms

Mayor de la Rosa expressed deep concerns about the decision-making trajectory in Weslaco's water project developments, focusing on transparency, public awareness, and financial matters. He emphasized his commitment to inclusivity and open governance, addressing questions about the project management fee paid to CDM. His meticulous approach to economic issues, including the allocation of engineering fees, aimed to ensure taxpayer funds were managed judiciously.

Despite de la Rosa's concerns, Mayor Pro-Tem Cuellar and Commissioner Adrian Gonzalez cast shadows over his expressions. Also notable was when addressing concerns raised by citizens like Richard Vaughan. Vaughan's dissatisfaction with the contract execution by Mayor Pro-Tem Cuellar without commission voting highlighted his unease, as he proposed alternative firms could offer lesser charges. Cuellar's intervention effectively silenced Vaughan's concerns, aiming to restrict discussions to the contract signature.

Commissioner Adrian Gonzalez's silence as a representative of the citizens raised questions about his role in the unfolding developments. The convergence of these voices shaped the course of Weslaco's water project, leaving the community grappling with the balance between transparency and power.

Choices in the Spotlight: Navigating Construction Management and the CDM Tie

As the project preparations unfolded, the City Commission started drafting plans for procuring the 2007 bond projects, especially the water and sewer projects, which were the most significant in the bond. Due to available funds, the commission decided that the best step was to focus on a larger wastewater plant and make some short-term renovations to the water treatment plant.

Because of the pricing inconsistencies, the commission adopted the Construction Managers at Risk (CMAR) method that CDM previously used in Rio Grande’s water plant project. The motion to approve the CMAR approach was supported by both Adrian and Cuellar.

CMAR Unveiled: A Dual-Role Dance with Origins of Influence

The Rio Grande region’s choice of the CMAR approach for their water project was a good driving argument in favor of Weslaco's water project using CMAR. According to the mayor of Rio Grande, the CMAR approach aims to deliver within a Guaranteed Maximum Price (GMP) but also presents unique challenges and opportunities.

With the CMAR approach, CDM was made the Construction Manager at Risk, but this decision faced some challenges and reservations.

State Representative Armando Martinez, a relative of mayor pro-Tem Cuellar, was supposed to address potential conflicts of interest in financial arrangements, but he didn’t. Russell Lenz, the director of the Association of General Contractors, emphasized the importance of checks and balances when merging designer and contractor roles within the CMAR framework.

Despite reservations, Commissioner Adrian Gonzalez and Mayor Pro-Tem Cuellar, along with the investment of the Cuellars and Gonzalezes, stifled resistance from both the commission and Weslaco's citizenry.

The CMAR approach and CDM's dual role as project overseer and construction manager at risk remained embedded in the project's evolution, showcasing intricate decision-making and influential maneuvering from Adrian.

The Transition of Power: The Shift from Adrian Gonzalez to Jerry Tafolla

As Adrian Gonzalez's term as a Weslaco commissioner ended, Commissioner Tafolla's win against Adrian seemed more like an orchestrated plan to bring another player in rather than a simple political loss. Tafolla referred to Adrian as a brother and dear friend, emphasizing the enduring nature of their relationship.

The transfer of responsibility from Adrian to Tafolla had broader implications, particularly concerning the city's ongoing water and sewer project. Tafolla was equally committed to this project, mirroring Adrian’s advocacy for CDM's involvement as project manager.

Tafolla's induction into the commission seemed orchestrated as a strategic handover from Adrian. It reflected a unified strategy to ensure the uninterrupted continuation of their shared objectives and vision for Weslaco's water and sewer project. This change in leadership underscored the intricate web of connections and agendas that emphasized the city's political landscape.

In Reflection: Unraveling the Intricate Tapestry of Actions and Outcomes

The water and sewer project in Weslaco, Texas, is a complex and mysterious story that highlights the pivotal role of former commissioner Adrian Gonzalez. His tenure led to a tapestry of intricate alignments, including Camp Dresser McKee's (CDM) engagement, which juggled the dual roles of supervisor and executor. The project's evolution led to a tapestry of collaborations, affiliations, and strategic maneuvers, with Mayor Pro-Tem Cuellar playing a significant role in the decision-making process.


During the project's transition into an FBI investigation, Adrian's absence prompted introspection about his actions and their potential influence on future choices. The narrative suggests that Adrian's priorities might have leaned towards personal gain over the welfare of his constituents. As citizens, it is crucial to scrutinize the choices underpinning Adrian's tenure, as his actions laid the groundwork for a labyrinthine corruption case.


The intricate saga of the water and sewer project serves as a cautionary tale for public office aspirants, reminding them that the implications of their actions can ripple beyond their time in power. As we navigate the future, may we internalize the teachings of the past and formulate choices harmonizing with the welfare of Weslaco's residents.
