BACKGROUND
Since 2021, Dopudja & Wells Consulting has provided professional consulting services to the City/RUA, developing a comprehensive understanding of the City's utility systems, regulatory obligations, and the complexities of the Concession Agreement. Given the complexity and historical context of the work performed, maintaining their services ensures seamless continuity, preserves valuable institutional expertise, and supports the City's ongoing efforts to optimize utility performance and compliance.
In March 2025, the City Council/Rialto Utilities Authority approved the Sixth Amendment to the Dopudja & Wells contract, authorizing support for as-needed services and interim utilities director support.
The City continues to utilize Dopudja & Wells to bridge staffing, gaps and support technical projects, including the Rialto Habitat and Nature Center (RHNC) and Cactus Basin recharge coordination. On October 30, 2025, the Water Subcommittee reviewed the Seventh Amendment proposal and provided feedback to move forward with presenting to the City Council/Rialto Utility Authority for approval.
ANALYSIS/DISCUSSION
The Seventh Amendment to the Dopudja & Wells PSA extends consulting support through February 2026 and adjusts scope and budget to reflect the direct contracting of one subconsultant, Scheevel Engineering, with the City.
The Dopudja & Wells Consulting - Seventh Amendment proposal dated October 1, 2025 includes four key tasks:
1. Additional Interim Staffing Support - Continued reduced-level interim management and analytical assistance to the Utilities Department through February 2026, led by Stephen Dopudja and Jason Pivovaroff, with financial support from John Rossi.
Cactus Basin Recharge Coordination - Multi-agency coordination among the San Bernardino Valley Water District, West Valley Water District, Fontana Union Water District, City of Colton, County of San Bernardino, and Emhart Industries to develop a framework for groundwater recharge at Cactus Basin.
RHNC Preliminary O&M Manual Support - Dopudja & Wells will continue limited coordination assistance as Scheevel Engineering assumes direct contract responsibility for the technical modeling and manual preparation.
Project Management and Administration - Budget oversight, coordination, and invoice processing for City-assigned tasks.
The total costs for Seventh Amendment services are $647,365. The proposed Task 1 through 4 fees and anticipated schedules are shown in Table 1 below:

Tasks include:
1. Stakeholder and agency coordination meetings.
