As related to the Kanawha PSD flood project, New River Engineers, Inc. (NREI) has prepared the following:
Between August 26, 2023, to August 29, 2023 the eastern part of Kanawha County experienced periods of heavy rainfall intensity, as much as 4 inches per hour in some areas. The rain event caused many of the streams within the PSD’s service area to overflow their banks causing damage to the existing infrastructure. The Winifrede and Coopers Hollow areas sustained heavy damage because of the severe weather event. Kanawha Public Service District (KPSD) is the local sanitary sewer provider. KPSD started evaluating the damage sustained to the sanitary sewer system as soon as personnel were able to return to work. KPSD was closed the day after the flooding event due to a power outage. KPSD personnel quickly realized that the damage assessment was going to require more man hours than its limited staff could provide. The PSD then contacted their current engineer, New River Engineers, Inc. (formerly S & S Engineers, Inc.) for assistance in assessing the damage.
The damage assessment was conducted in the following phases.
1. The first phase involved talking to KPSD personnel regarding issues they discovered either by being notified by a resident or by discovering the issue themselves. The primary purpose of this phase was to focus attention on the areas most likely to have sustained damage and identify issues as quickly as possible. Completed August 2023.
2. The second phase involved NREI personnel walking the existing collection system lines in the areas of concern to determine apparent damage, determine access availability, take pictures, take measurements, and generally assess the current condition of the collection system. Completed September 8, 2023.
3. The third phase involved closed circuit camera inspection of the sewer collection system in the areas of concern. Completed September 30, 2023.
4. The fourth phase involved analyzing the collected data, developing a recommended repair strategy with associated cost, and finalizing the report. Completed October 2023.
The Federal Emergency Management Agency (FEMA) was contacted regarding financial assistance for the necessary repairs. Several months elapsed between the initial request for aid and the site inspection. The site inspection with FEMA representatives was conducted on April 8 through 10 of 2024. In May 2024, the decision was made to attempt to clean the sections of the sanitary sewer system that were too obstructed by flood debris to video inspect. If the cleaning is successful, the line will be video inspected to determine if further flood-related deficiencies exist. FEMA and the State of West Virginia required KPSD to comply with the SG engineering procurement process prior to receiving funding. If cleaning is unsuccessful, video inspection will be used to demonstrate why the line could not be cleaned. If the lines could be cleaned and no other flood related issue was identified, then the line would be removed from the sections slated for replacement. KPSD was notified in July 2024 that FEMA had allocated the funds for the cleaning project. However, the FEMA funds only cover 75% of the associated cost. Therefore, KPSD started applying to the State of West Virginia for the matching 25%. The matching funds were allocated later in July 2024 . The sanitary sewer cleaning work started on July 29, 2024, and is ongoing as of the date of this letter.
The cleaning work is expected to be completed by the end of August 2024. The data will be analyzed, and a design report will be developed for the finalized scope. Plans and Specifications will be developed, and the necessary permits obtained. The project will then have to be let out to bid . The anticipated schedule for the project is as follows:
Completion of line cleaning | Complete | ||
Approval from FEMA of revised scope | January 1, 2025 | ||
Plans and Specifications complete | March 1, 2025 | ||
Permit applications submitted | March 15, 2025 | ||
Additional funding committed | April 30, 2025 | ||
Advertise for bid | June 15, 2025 | ||
Bids received | July 30, 2025 | ||
Begin Construction | October 30, 2025 | ||
Substantial Completion | October 30, 2026 | ||
The schedule above is based on typical project timelines. However, KPSD is committed to completing the repairs as quickly as possible to prevent additional issues. Unfortunately a project of this magnitude is tedious process. Your patience is greatly appreciated.
