Section 1 Introduction & Project Overview

1.1 Purpose

The Cities of Covington and Oxford (“Owners”) are requesting proposals to select a qualified company (“Proponent”) to provide Micro-Detection to identify Rainfall Derived Infiltration and Inflow (RDII). The purpose of this Request for Proposals is to solicit pricing and qualifications from qualified companies interested in and experienced in providing the services requested herein. The RFP evaluation and selection of a Proponent will be finalized within 60 days from the submittal date. Funding is through local funds.

1.2 Background

The Cities of Covington and Oxford have approximately 154,000 linear feet of various diameter sanitary sewer mains within the Turkey Creek Sanitary Sewer Basin. The Owners’ sanitary sewer is discharged to Newton County Water & Sewerage Authority’s (NCWSA) through the Turkey Creek Interceptor. In 2024, NCWSA completed a flow study for this Interceptor and identified significant increases in the flow resulting from RDII.

In order to accommodate future flows in the system, the Cities’ desire to identify inflow and infiltration to facilitate a future repair and rehabilitation project. Therefore, the Owners are moving forward with a micro-detection program to identify RDII contributors for effective rehabilitation efforts.

A Purchase Order will be issued by the OWNERS for the services provided based on the pricing negotiated for the program. Services related to the work will be authorized through separate contracts with each of the two Owners. Therefore, the OWNERS maintain the option to select the same Proponent or different Proponents for the project.

See the “Turkey Creek Basin Flow Monitoring Evaluation” in Appendix I for a map of sanitary sewer service areas.

TECHNICAL MEMORANDUM

Turkey Creek Basin Flow Monitoring Evaluation

DATE: August 21, 2025

TO: Mr. Kevin Sorrow and Mr. Bill Andrew

FROM: Carter & Sloope, Inc.

RE: City of Covington and City of Oxford

Turkey Creek Basin Micro-Detection

C & S Project No.: C8370.040 & O9800.011

The purpose of this technical memorandum is to present the evaluation of the Sewer Flow Monitoring

Report for Newton County Water & Sewerage Authority (NCWSA) in May 2024, respective to the

City of Covington and the City of Oxford, specifically within the Turkey Creek Basin. The report presents the flow monitoring data of the Turkey Creek Sanitary Sewer Basin which extends into the

City of Covington and City of Oxford sewer service area. C&S reviewed the data collected in the report to identify and rank the likelihood of rain derived inflow and infiltration (RDII) and separated it to their respective Service Provider.

Evaluation

As noted in the Sewer Flow Monitoring Report, a total of seven data loggers were installed in the

Turkey Creek Sanitary Sewer Basin (Figure 1). The data collection was to evaluate both dry-weather and wet-weather periods to quantify what RDII may occur during wet-weather events. Following the initial setup an additional sub-basin was added due to found conditions. Significant rain events occurred during the monitoring period that were acceptable for analysis. Based on the RDII analysis and surcharge information, RDII is attributing to the collected flow and subsequent surcharge events recommends further investigation.

C&S reviewed the data and ranked the likelihood of RDII (Table 1) by service area associated with the flow monitor location. The sewer length provided was calculated from the GIS data within the report and should be considered an estimation. The footage of the NCWSA’s Turkey Creek

Interceptor within these areas was not included.

The areas monitored by FM 1, FM 1A, FM 2, and FM 3 are primarily served by the City of

Covington (Figure 2). The areas monitored by FM 4, FM 5, FM 6, and FM 7 are primarily served by the City of Oxford (Figure 3). There are some overlap of service areas that are being reviewed. Of

City of Covington and City of Oxford note, the data collected at FM 4 includes the neighborhood within the Stone Street and Haygood

Avenue area that is served by the City of Covington.

Recommendation

C&S recommends further investigation of these areas to locate where appropriate remedies should be implemented to reduce RDII in the sewer system that is being collected in the NCWSA’s Turkey

Creek Interceptor. We propose to develop a request for proposal (RFP) to solicit pricing and qualifications from qualified companies interested in and experienced in providing micro-detection of RDII services beyond the interceptor. Based on the proposals and costs, each City can select the program and service area that fits their budget.

5.4.2 Deny liability in whole or in part and notify the Owner, citing the reasons for denial.

6. If the Surety does not proceed as provided in Paragraph 5 with reasonable promptness, the Surety shall be deemed to be in default on this Bond seven days after receipt of an additional written notice from the Owner to the Surety demanding that the Surety perform its obligations under this Bond, and the Owner shall be entitled to enforce any remedy available to the Owner. If the Surety proceeds as provided in Paragraph 5.4, and the Owner refuses the payment, or the Surety has denied liability, in whole or in part, without further notice, the Owner shall be entitled to enforce any remedy available to the Owner.

If the Surety elects to act under Paragraph 5.1, 5.2, or 5.3, then the responsibilities of the Surety to the Owner will not be greater than those of the Contractor under the Construction Contract, and the responsibilities of the Owner to the Surety will not be greater than those of the Owner under the Construction Contract. Subject to the commitment by the Owner to pay the Balance of the Contract Price, the Surety is obligated, without duplication for:

7.1. the responsibilities of the Contractor for correction of defective work and completion of the Construction Contract;

7.3. liquidated damages, or if no liquidated damages are specified in the Construction Contract, actual damages caused by delayed performance or non-performance of the Contractor.

8. If the Surety elects to act under Paragraph 5.1, 5.3, or 5.4, the Surety’s liability is limited to the amount of this Bond.

9. The Surety shall not be liable to the Owner or others for obligations of the Contractor that are unrelated to the Construction Contract, and the Balance of the Contract Price will not be reduced or set off on account of any such unrelated obligations. No right of action will accrue on this Bond to any person or entity other than the Owner or its heirs, executors, administrators, successors, and assigns.

10. The Surety hereby waives notice of any change, including changes of time, to the Construction Contract or to related subcontracts, purchase orders, and other obligations.

11. Any proceeding, legal or equitable, under this Bond must be instituted in any court of competent jurisdiction in the location in which the work or part of the work is located and must be instituted within two years after a declaration of Contractor Default or within two years after the Contractor ceased working or within two years after the Surety refuses or fails to perform its obligations under this Bond, whichever occurs first. If the provisions of this paragraph are void or prohibited by law, the minimum periods of limitations available to sureties as a defense in the jurisdiction of the suit will be applicable.

12. Notice to the Surety, the Owner, or the Contractor must be mailed or delivered to the address shown on the page on which their signature appears.

13. When this Bond has been furnished to comply with a statutory or other legal requirement in the location where the construction was to be performed, any provision in this Bond conflicting with said statutory or legal requirement will be deemed deleted therefrom and provisions conforming to such

1. The Contractor and Surety, jointly and severally, bind themselves, their heirs, executors, administrators, successors, and assigns to the Owner to pay for labor, materials, and equipment furnished for use in the performance of the Construction Contract, which is incorporated herein by reference, subject to the following terms.

2. If the Contractor promptly makes payment of all sums due to Claimants, and defends, indemnifies, and holds harmless the Owner from claims, demands, liens, or suits by any person or entity seeking payment for labor, materials, or equipment furnished for use in the performance of the Construction Contract, then the Surety and the Contractor shall have no obligation under this Bond.

3. If there is no Owner Default under the Construction Contract, the Surety’s obligation to the Owner under this Bond will arise after the Owner has promptly notified the Contractor and the Surety (at the address described in Paragraph 13) of claims, demands, liens, or suits against the Owner or the Owner’s property by any person or entity seeking payment for labor, materials, or equipment furnished for use in the performance of the Construction Contract, and tendered defense of such claims, demands, liens, or suits to the Contractor and the Surety.

4. When the Owner has satisfied the conditions in Paragraph 3, the Surety shall promptly and at the Surety’s expense defend, indemnify, and hold harmless the Owner against a duly tendered claim, demand, lien, or suit.

5. The Surety’s obligations to a Claimant under this Bond will arise after the following:

5.1. Claimants who do not have a direct contract with the Contractor

5.1.1. have furnished a written notice of non-payment to the Contractor, stating with substantial accuracy the amount claimed and the name of the party to whom the materials were, or equipment was, furnished or supplied or for whom the labor was done or performed, within ninety (90) days after having last performed labor or last furnished materials or equipment included in the Claim; and

5.1.2. have sent a Claim to the Surety (at the address described in Paragraph 13).

5.2. Claimants who are employed by or have a direct contract with the Contractor have sent a Claim to the Surety (at the address described in Paragraph 13).

6. If a notice of non-payment required by Paragraph 5.1.1 is given by the Owner to the Contractor, that is sufficient to satisfy a Claimant’s obligation to furnish a written notice of non-payment under Paragraph 5.1.1.

7. When a Claimant has satisfied the conditions of Paragraph 5.1 or 5.2, whichever is applicable, the Surety shall promptly and at the Surety’s expense take the following actions:

7.1. Send an answer to the Claimant, with a copy to the Owner, within sixty (60) days after receipt of the Claim, stating the amounts that are undisputed and the basis for challenging any amounts that are disputed; and

7.2. Pay or arrange for payment of any undisputed amounts.

7.3. The Surety’s failure to discharge its obligations under Paragraph 7.1 or 7.2 will not be deemed to constitute a waiver of defenses the Surety or Contractor may have or acquire as to a Claim, except as to undisputed amounts for which the Surety and Claimant have reached agreement.

If, however, the Surety fails to discharge its obligations under Paragraph 7.1 or 7.2, the Surety shall indemnify the Claimant for the reasonable attorney’s fees the Claimant incurs thereafter to recover any sums found to be due and owing to the Claimant.

8. The Surety’s total obligation will not exceed the amount of this Bond, plus the amount of reasonable attorney’s fees provided under Paragraph 7.3, and the amount of this Bond will be credited for any payments made in good faith by the Surety.

9. Amounts owed by the Owner to the Contractor under the Construction Contract will be used for the performance of the Construction Contract and to satisfy claims, if any, under any construction performance bond. By the Contractor furnishing and the Owner accepting this Bond, they agree that all funds earned by the Contractor in the performance of the Construction Contract are dedicated to satisfying obligations of the Contractor and Surety under this Bond, subject to the Owner’s priority to use the funds for the completion of the work.

10. The Surety shall not be liable to the Owner, Claimants, or others for obligations of the Contractor that are unrelated to the Construction Contract. The Owner shall not be liable for the payment of any costs or expenses of any Claimant under this Bond, and shall have under this Bond no obligation to make payments to or give notice on behalf of Claimants, or otherwise have any obligations to Claimants under this Bond.

11. The Surety hereby waives notice of any change, including changes of time, to the Construction Contract or to related subcontracts, purchase orders, and other obligations.

12. No suit or action will be commenced by a Claimant under this Bond other than in a court of competent jurisdiction in the state in which the project that is the subject of the Construction Contract is located or after the expiration of one year from the date (1) on which the Claimant sent a Claim to the Surety pursuant to Paragraph 5.1.2 or 5.2, or (2) on which the last labor or service was performed by anyone or the last materials or equipment were furnished by anyone under the Construction Contract, whichever of (1) or (2) first occurs. If the provisions of this paragraph are void or prohibited by law, the minimum period of limitation available to sureties as a defense in the jurisdiction of the suit will be applicable.

13. Notice and Claims to the Surety, the Owner, or the Contractor must be mailed or delivered to the address shown on the page on which their signature appears. Actual receipt of notice or Claims, however accomplished, will be sufficient compliance as of the date received.

14. When this Bond has been furnished to comply with a statutory or other legal requirement in the location where the construction was to be performed, any provision in this Bond conflicting with said statutory or legal requirement will be deemed deleted here from and provisions conforming to such statutory or other legal requirement will be deemed incorporated herein.
