Specifically, the F +1 (732) 577 0551 www.mottmac.com meter and recorder have been instrumental in identifying the nature of storm related influent flow spikes which quickly reach the station during a rain event. During the month of July, there were several high- intensity rain events which have been recorded by the chart recorder and reviewed by Mott MacDonald. It was discovered that during the rain events, the pump station becomes inundated by peak inflow in excess of 5 -times the base flow within less than 30- minutes. This quick spike in flow is far beyond the station's rated conveyance capacity and as a result, the wet well quickly becomes surcharged. Based on the nature of the rapidly increasing flow during the rain events, it is highly likely that there are cross connections of the Borough's storm sewer to the sewer system. Identifying and removing these cross connections would have a significant impact on the flow going through the pump station and as a result, reduce costs paid to the Middlesex County Utilities Authority in user charges. Storm Analysis Mott MacDonald has reviewed the chart recorder data for four high- intensity rain events that occurred on July 1s', July 61h, July 91h, and July 171h and noticed very similar patterns of a rapid spike in the flow immediately seen at the onset of precipitation. Based on the flow chart data, provided in Attachment 1, the summary of the storm inflow and estimated costs are as follows: Rain Event Date Estimated Storm Inflow Volume Estimated Cost To Borough July 1, 2021 249,840 gal $ 499.68" July 6, 2021 6,912,240 gal $ 13,824.48" July 9, 2021 14,449,080 gal $ 28,898.16' July 17, 2021 5,142,540 gal $ 10,285.08' Total Estimated Cost to Borough $ 63,507.40` M 'Estimated storm costs were calculated using an assumed MCUA user rate for the Borough of M$2,000 per million gallons of wastewater received. MOTT Most notably, the July 91h storm was the largest and most intense storm experienced MACDONALD by the pump station during July. This storm had multiple waves of impact to the pump station, with peak flows up to the maximum allowable flow of 13.3 MGD for prolonged periods of 8 hours, followed by decreases in flow between each peak which also lasted for multiple hours. By the end of this storm event, roughly 14,449,080 gallons were pumped by the station resulting in an estimated cost to the Borough of $28,898.16. It must be stressed that this is a summary of only four events over the month of July. Over the course of a year, the 40 -50 events that are commonly experienced likely result in costs to the Borough exceeding $500,000. In addition to the cost impact to the Borough as explained above, intense storm events have had an impact on the pump station operations with flooding of the wet well area, which requires extensive cleaning and removal of rags and debris. If the wet well floods to high elevations, there is also a risk of surcharge in gravity sewer manholes upstream of the pump station. Proposed Investigation Mott MacDonald's approach to this project will include a close working relationship with the Borough in order to complete the work in a timely manner. We propose to perform the following scope of work to assist the Borough with this sewer investigation: Task 1 — Topside Manhole Inspections Mott MacDonald will inspect up to 20 sanitary sewer manholes within Roosevelt Avenue between Charles Street and the Roosevelt Avenue Pump Station. The inspections will be conducted from the topside or at -grade (manhole entry will not be required). We will utilize the manhole number system provided on the Borough's GIS database for each inspected sanitary sewer manhole. All manhole inspections will be assessed by NASSCO MACP© certified Mott MacDonald personnel. The inspections will include preliminary surface inspections to consider the internal condition of the manhole structure, frame and cover, and observed sources of extraneous flow with particular focus on evidence of any cross - connections to storm sewers or adjacent waterbodies. Each manhole inspection will be documented by utilizing Mott MacDonald's "Manhole Inspection Report" cards which include general information such as municipality, manhole number, location, weather conditions, etc. and detailed information such as a sketch of the manhole, pipes entering the manhole, digital photographs taken and their description, and conditions and observations taken of the manhole. We will provide the Borough with an inspection report of each manhole including a listing of all manholes that were inaccessible (i.e. buried, could not be opened) so the inspection can be obtained at a later date. We will provide recommendations for system rehabilitation to correct identified deficiencies based on the completed manhole inspections. Task 2 — Sanitary Sewer Smoke Testing We propose to conduct smoke testing throughout Area 1 of the Borough, as shown in Attachment 2, up to 10,000 linear feet. The purpose of the smoke testing is to detect potential sources of Infiltration and inflow (W) by blowing a non -toxic smoke September f, 20211 Page 2 of 4 Mthrough isolated segments of the sanitary sewer service pipes connected thereto. M The smoke can be blown for the length of several manholes at each setup and will MOTT enable Mott MacDonald personnel to verify penetration throughout the sanitary MACDONALD sewer reaches by observing smoke emanating from the plumbing vent stacks of houses that are connected to the sewers. Mott MacDonald field personnel will note any smoke emanating from points other than plumbing vent stacks, which indicate possible sources of 1/1 including: roof downspouts; driveway /pathway drains; yard drains; building basements and /or foundations; storm sewer cross - connections; manhole frames and risers; and the ground (suggesting pipe defects). Prior to beginning any smoke testing, we will provide proper community awareness by issuing door tags, prepared by Mott MacDonald, within one (1) week of the testing to all affected residents and facilities, as well as police and fire operations describing the purpose and procedures of smoke testing, providing answers to frequently asked questions, and including a cellular phone number of the field crew chief. We will submit the door tag to the Borough for approval prior to issuing them to residents. Under dry weather conditions, we will introduce a non -toxic smoke through isolated segments of the sanitary sewer pipelines using smoke candles and our Briggs /Stratton 120000 smoke blower. Mott MacDonald personnel will document in report format and with digital photos any unusual /improper discharges, which indicate sources of 1/1 as described above. One (1) workday with a 3- person crew has been assumed to complete the smoke test investigation. Task 3 — Project Report Mott MacDonald will prepare a formal project report that summarizes all tasks, findings and recommendations including tabulation and maps of our manhole inspection findings and smoke testing results. Mott MacDonald will develop a comprehensive tabulation of recommended rehabilitation and maintenance to correct wastewater collection system deficiencies identified from our investigations. Our proposal is based on the following assumptions: • Sanitary sewer manholes are readily accessible and can be opened with a manual hook. • Traffic control beyond a few traffic cones and the Contractor vehicles in not included in this Proposal. Fees Mott MacDonald will complete the three (3) tasks as described herein for the following lump sum fees: Task Description Fee 1 Topside Manhole Inspections $3,500 2 Sanitary Sewer Smoke Testing $8,000 3 Project Report $3,000 Total Cost $14,500 September t, 20211 Page 3 of 4 M MOTT ' " M MACDONALD September 1, 20211 Page 4 of 4 Mott MacDonald proposes to complete the tasks described herein for the lump sum fees shown above. The Borough would be billed monthly predicated upon the percentage of work completed during each billing cycle. We trust the foregoing scope of work adequately addresses the needs and requirements of the Borough of Carteret at this time. We are able to initiate this project immediately upon your authorization.
