King George service authority seeks short-term financing to fund Dahlgren plant fixes; engineers outline $4M in near-term work

Dahlgren wastewater officials and outside consultants told county leaders on June 3 that immediate repairs and upgrades at the Dahlgren wastewater treatment plant are needed to meet state discharge limits and avoid future enforcement. Davenport & Company, the service authority's financial adviser, recommended interim financing of roughly the amount of the near-term needs to preserve the utility's cash balance and maintain flexibility for possible grants, while Bowman and TRC engineers presented technical fixes and cost estimates.

The service authority and county heard three linked presentations: Davenport outlined a funding strategy for about $4 million of immediate capital work; Bowman Engineering described priority upgrades at the Dahlgren plant (aeration system replacement, improved internal recycling pumps, blower replacement and influent-pump-station rehabilitation); and TRC presented a preliminary engineering report to evaluate decommissioning Oakland Park and rerouting flows to Hopyard/Dahlgren if that proves practical.

Davenport recommended short-term interim borrowing with a 2-to-5-year maturity. David Rose, Davenport's financial adviser, told the service authority board that borrowing short-term preserves the utility's roughly $8.5 million cash balance so it continues to earn interest; the interest earned on that balance roughly offsets the likely interim financing cost. That approach, Rose said, keeps the authority's options open: if grants or other cash become available later the short-term debt can be paid down; if not, the authority can convert any remaining interim loan to long-term financing. Rose said the interim step also protects credit standing and flexibility for larger future projects.

Engineers described near-term technical work they say is necessary for permit compliance. Bowman's presentation identified four high-priority improvements: replacing the plant's aging surface aerators with above-the-surface mechanical mixers that are easier to maintain and control (budget: $2.9 million including contingency and engineering); installing a mechanical high-rate internal recycle pump and flow metering to improve biological nutrient removal (budget: about $830,000); replacing unsupported blower equipment (estimated $825,000); and rehabilitating the influent pumping station's corroded piping, valves and interior concrete so staff can access and maintain valves and pumps (about $254,000). Engineer representatives said estimates include contingencies and preliminary design and will be refined during full design.

Separately, TRC and the service authority are finalizing a preliminary engineering report (PER) on decommissioning Oakland Park Wastewater Treatment Plant and sending flows to Hopyard/Dahlgren. TRC said the PER draft needs additional financial inputs from the authority before it can be finalized; the consultant and county staff agreed to produce requested financial detail and additional edits so the PER can be completed by the end of June for board review in July.

Board and service-authority members pressed for additional details on exact costs, electrical service capacity, and whether interim borrowing would lead to higher rates. Service-authority staff said they will examine the utility's cash flow and interest allocations (treasury interest currently going to the pooled county account) and said some corrective accounting steps have already been initiated so the Water & Sewer Fund receives interest revenue it should have been paid in prior years.

Actions and next steps

- The King George Service Authority directed its advisers to solicit proposals for interim financing. Davenport was authorized to work with bond counsel to distribute an RFP to potential lenders and return results to the boards for decision (motion passed; one board member abstained). The authority will seek financing terms designed to allow quick payoff if grants arrive. - Consultants and staff agreed to finalize the Dahlgren immediate-needs design and to return refined cost estimates. TRC agreed to finish the Oakland Park PER after receiving additional financial data by the end of June. - The county's finance and service-authority staff will run updated cash-flow scenarios and compute the likely impact on rates under different financing choices. Staff said they will present results to the boards before any permanent borrowing decision.

Why this matters

The Dahlgren plant currently faces increasingly stringent nutrient permit requirements. Engineers said existing equipment and single points of failure make meeting the permit unreliable; state enforcement and fines are an explicit risk if performance does not improve. The proposed interim financing balances near-term compliance and long-term rate pressures by preserving interest-earning cash while allowing immediate repairs.

"If you take that $4 million out of your fund balance, you'll lose the interest earnings that help minimize pressure on user rates. We recommend interim financing so you keep your powder dry," David Rose, financial adviser, Davenport & Company.

"These basins are difficult to dewater and the current units have reached the end of their useful life. Above-surface mechanical mixers will be easier to maintain and control," Jeff Crowellinger, Bowman Engineering (engineer presentation).

Ending

Consultants recommended a cautious three-step path: finalize technical designs and refined estimates, solicit short-term interim financing to preserve flexibility and interest earnings, then convert or pay down the interim debt if grants or other cash becomes available. Authority and county staff will present firm financing bids and refined designs at upcoming meetings for formal decisions.
