Technical, managerial, and financial capacity assessments — SWRCB-ready documentation, compliance improvement plans, and DDW communication support for small and medium public water systems in California and Nevada.
Technical, Managerial, and Financial (TMF) capacity refers to a water system's ability to operate and maintain compliance with drinking water standards over the long term. The State Water Resources Control Board (SWRCB) uses TMF assessments to evaluate whether a water system has the infrastructure, qualified personnel, and financial resources to sustain safe, reliable water service to its customers.
If your water system has received a SWRCB compliance order, is undergoing a change of ownership, is applying for a new permit, or has been flagged for TMF deficiencies — you need a consultant who understands both the regulatory framework and the day-to-day operational reality of running a small water system.
Aqua Solutions Consulting provides SWRCB-ready TMF capacity assessments, capacity improvement plans, and SB 1188 compliance documentation for small and medium public water systems in California and Nevada.
A proactively prepared TMF assessment — developed before a compliance action — gives your board and management the clearest possible picture of where you stand, and the documentation needed to demonstrate good-faith compliance efforts to DDW.
Waiting until DDW initiates action limits your options and compresses your timeline. Systems that engage a consultant early consistently achieve better outcomes.
TMF assessments are triggered by several regulatory circumstances. If any of the following apply to your system, you may need to complete or update a TMF evaluation.
All new community water systems must demonstrate adequate TMF capacity as part of the permitting process before beginning operations.
When a water system changes ownership — including mutual water company board transitions or property transfers — SWRCB may require a fresh TMF evaluation.
Senate Bill 1188 requires that certain water systems receiving state or federal funding, or seeking SWRCB approval for system changes, demonstrate adequate TMF capacity.
Systems that have received a Compliance Schedule Order, Notice of Violation, or other enforcement action from DDW may be required to complete a TMF assessment as part of their corrective action plan.
If a DDW sanitary survey identifies significant deficiencies in your system's infrastructure, management, or finances, a TMF assessment may be required as part of the corrective action.
Water systems considering consolidation with another system, or being evaluated for consolidation by the state, will typically undergo TMF review as part of the process.
Every TMF assessment evaluates your system across three interconnected dimensions. Deficiencies in any one area can trigger regulatory action — and improvement in all three is required for long-term compliance.
Physical infrastructure and operational capability — the condition of your facilities and the qualifications of the operators running them.
Organizational structure, policies, and decision-making processes to operate in compliance over time.
Whether your system generates sufficient revenue to cover operations, fund capital improvements, and maintain financial reserves.
Our TMF assessment process produces SWRCB-ready documentation — not just a general report, but a structured evaluation that meets SWRCB's capacity development framework and supports your system's compliance pathway.
A structured evaluation of your system's technical, managerial, and financial capacity — organized to align with SWRCB's capacity development framework and DDW review standards.
A clear inventory of identified deficiencies by TMF category, with regulatory basis, severity rating, and recommended corrective action for each gap.
A prioritized, time-bound action plan addressing each identified deficiency — formatted to meet SWRCB compliance schedule requirements and defensible under DDW review.
All documentation formatted and organized for direct submission to your DDW District Office or SWRCB program manager — ready to file on delivery.
Assessment of current operator certifications versus system classification requirements, with recommendations for any certification gaps identified.
A plain-language review of rate structure adequacy and reserve fund status — suitable for presentation to your board of directors at your next meeting.
Senate Bill 1188 (Water System Consolidation) established requirements for water systems to demonstrate TMF capacity in connection with specific state actions — including state funding assistance, permit modifications, and consolidation proceedings.
Under SB 1188, water systems must demonstrate adequate TMF capacity in several key circumstances:
Many small water systems — mutual water companies, HOA-operated systems, and small CWS — have never undergone a formal TMF evaluation. This creates significant regulatory exposure, particularly if the system is already struggling with compliance issues.
A proactive Aqua Solutions TMF assessment identifies where your system stands today, documents good-faith corrective efforts, and provides the board with a clear roadmap before DDW or SWRCB initiates action.
Start with a call. Aqua Solutions will conduct a no-cost initial review of your system's compliance history, permit status, and any DDW correspondence — then provide a clear scope and cost estimate for a full TMF assessment. Most small systems can complete the full process in 4–8 weeks from engagement to final report.
Yes. We can communicate directly with your assigned DDW District Office or SWRCB program manager on your behalf — coordinating document submissions, responding to DDW questions or requests for additional information, and representing your system's compliance efforts throughout the process.
Yes. Mutual water companies that serve as community water systems (CWS) are subject to full SWRCB oversight and TMF capacity requirements. The cooperative or nonprofit ownership structure does not exempt the system from state drinking water regulations. Mutual water companies with volunteer boards are exactly the type of system Aqua Solutions is built to serve.
For a small system (fewer than 500 connections), a full TMF assessment and Capacity Improvement Plan typically takes 4–8 weeks from engagement to final report. Timeline depends primarily on the availability of existing records and access to key personnel for interviews. We work efficiently and communicate clearly at every step.
Yes — this is one of the most time-sensitive situations we handle. Contact us immediately. We will review your compliance order, assess your current TMF status, and help you develop a credible, defensible response and corrective action plan within DDW's required timeframes. Do not let DDW deadlines pass without a formal response — the consequences of non-response are severe.
A Technical, Managerial, and Financial (TMF) capacity assessment evaluates whether a public water system has the resources to consistently provide safe, reliable drinking water. California's SB 1188 requires the State Water Resources Control Board (SWRCB) to assess small water systems for TMF capacity — and to require corrective action when deficiencies are found. Aqua Solutions Consulting prepares complete TMF capacity assessments and improvement plans designed for DDW submission.
SB 1188 (California Senate Bill 1188) requires the SWRCB to assess the TMF capacity of water systems that consistently violate drinking water standards or face serious compliance challenges. Systems that fail the TMF assessment may be required to develop improvement plans, consolidate with other systems, or transfer management to a new operator. Proactively preparing a TMF assessment is one of the best ways a small water system can demonstrate regulatory good faith.
A typical TMF capacity assessment for a small community water system takes 3–6 weeks depending on system complexity, data availability, and the responsiveness of system management. Aqua Solutions Consulting works directly with your board or management to gather the necessary technical, operational, and financial data — and formats the final deliverable for direct DDW submission.
Yes. If your system is facing pressure to consolidate with a neighboring system — whether voluntary or regulator-driven — we can assist with feasibility documentation, comparative analysis, and the compliance narrative that accompanies a consolidation proposal to the Division of Drinking Water.
Whether your system has received a compliance order, is planning a change of ownership, is preparing for a DDW sanitary survey, or simply wants to understand where it stands — Aqua Solutions Consulting provides a clear, credible, SWRCB-ready TMF assessment.
