EXHIBIT A Greater Accuracy, Less Maintenance Hach Solitax sc sensors provide accurate, color- independent measurement of turbidity and suspended solids in drinking water, wastewater and industrial process applications. A self-cleaning device prevents biological growth and interference of gas bubbles. This system’s reliable performance and full data communication capability help improve process control and reduce treatment costs associated with polymer use, digester volume, and sludge handling. Excellent Correlation to Laboratory Analysis Solitax sc sensors show an exceptional correlation to laboratory analysis. On-line measurement not only saves time on manual analysis, but also provides critical real-time measurements that can be used to operate the plant more efficiently. Fully Serviceable Sensors Conventional turbidity and suspended solids sensors are potted and are discarded when they no longer function. Solitax sc sensors are fully serviceable, which often doubles the useful life of the sensor. Easy One-point Calibration Factory calibrated in conformity with DIN EN ISO 7027 for long-term calibration stability. Calibration is easy with a simple correction factor procedure. Multi-channel, Multi-parameter System Any two Solitax sc sensors can be installed on one Hach SC200 Controller. The same controller can also accommodate any combination of parameters. All of Hach’s model sc sensors are “plug and play” with no complicated wiring or set-up procedure necessary. Accurate, color-independent suspended solids and turbidity measurements.

Subject: Centrysis Recommendation for Field Modifications Spec Sections/Drawing Nos.: Information Request: During Centrysis initial startup checkout there are field modifications they recommending be implemented. The recommended modifications is as follows: Dewatering Centrifuge Feed Line Recommendation Centrysis has two concerns; 1) the feed hose is short and removing it via camlock isn’t feasible, and 2) the sample port is in a “dead zone at the end of a tee. It is Centrisys recommendation to remove the 6” Vic Tee at the end of the DIP feed line and relocate the 3” feed hose through a camlock 90 to increase the length of the feed hose (this will allow easier removal of the feed hose for operator maintenance). The sample port on the end of the tee will be relocated to the tee on the feed line of the Centrifuge. Dewatering Centrifuge Solids Sampling Recommendation Currently there is no location for solids sampling. Centrisys suggests adding a 2” sample port on the solids discharge hopper. This will be field welded in place and utilize a “spoon” made out of 2” sched 10 SST tubing that can be inserted into the hopper to collect discharged cake. Thickening Centrifuge Polymer Supply Piping The thickening centrifuge polymer is currently supplied by the 1 ½” PVC polymer piping. The thickening centrifuges have a ¼” polymer supply port on the inlet side of the centrifuge and they tying into the 1 ½” PVC polymer pipe with ¼” tubing to their polymer supply port on the feed piping. Please review and confirm it is acceptable to provide the field modification recom mended by Centrysis initial checkout & startup inspection. Potential Cost Impact?

Date: 6/10/2025 Attention: The following change in the contract on this project is proposed. Please provide the proposed price for the cost of this change. • A full breakdown of labor, equipment, and material costs shall be provided. • Work shall not commence until authorized by the Owner. Description of the Proposed Change: Item #1: Access to the Polymer skids HMI screens for viewing and interaction is difficult for operations staff due to the proximity of a narrow step. City operations has asked to pour a concrete step along the west side of the curb in front of the polymer skids so that staff can better access the HMI screens. The concrete extension shall be 12” wide, length to match the curb (~9.2’), depth to match the curb elevation (~7.5”). The nosing shall be edged as a step with stair grooves created with a jointer, painted safety yellow (by owner), medium broom finish for traction. #5 rebar along the face, epoxied into each end. Epoxied Rebar dowels at 12” along the perimeter with epoxied corner bar (consistent with other elevated slabs/curbs). Provide 2” clear cover between bars and the forms/top/bottom/sides and embedding the dowels 4”. Avoid drilling through existing bars when installing the dowels. Concrete design same as elevated slabs/curbs, 5000 psi interior w/ fiber. Item #2: The City WWTP Operations Staff are washing out polymer totes at SDCB #3. SDCB #3 is connected to the gravity sewer that flows to Maitland Lift Station. The SDCB is not channeled and has a ~ 24” collection area below pipe invert (per City catch basin detail, C- 002, SD-2). Polymer is collecting in the sump area until it finally moves, releasing a large ‘blob’ of polymer that is eventually found in the primary clarifiers. City Operations Staff would like to fill this space with concrete and channel the flow from all inlets/outlets so that the polymer will not collect. Work includes cleaning the catch basin, filling the sump with concrete, creating a shelf, and creating a channel for inlets and outlet. Concrete should be minimum 3000 psi per spec and may be higher psi to avoid short orders of concrete. Coordinate work with Todd Marden and Mike Soucie to determine extent of work and components of work. By Mark Cummings All work shall be in accordance with the terms, stipulations, and conditions of the original Contract Documents. If the work herein provided for is Approved by Change Order, the time of completion will be: Consor, Inc.

All concrete shrinks to some extent after it’s poured, but the longitudinal #5 in the curb should help to minimize cracking as it shrinks longitudinally. Minor hairline cracking is possible/inherent but maintaining good curing practices per spec to avoid premature/excessive shrinkage will help. Thanks, Troy Troy M.

Hi Troy, I may just be missing it but did they state how they were treating the expansion between the exist curb and the new pour? Do they need to worry about that. I have typically seen that even with rebar dowels the expansion between can be problematic. Should they be putting in something that allows for some expansion between the existing and new concrete? If not, why not?
