Explanation
1. BACKGROUND: The Southerly Wastewater Treatment Plant (SWWTP) operates four (4) chlorination and post aeration basins as part of the disinfection treatment process. The current PVC air pipe and ceramic diffuser system was installed in 2006 as part of S69. Due to age and UV exposure, the PVC legs are failing at an accelerated rate. This issue is compounded due to the discontinuation of the air distribution leg by the original equipment manufacturer. This project will replace the post aeration diffusers, replace two centrifugal blowers with hybrid type blowers, rehabilitate three centrifugal bowers, replace the post aeration supply piping, replace and/or repair tank train valves and actuators, sensors and controls for to provide a more automated and energy efficient post aeration system, and other appurtenances to provide a fully post aeration system.
1.1 Project Renewal #1: $1,163,648.47
ORIGINAL CONTRACT (PO 133258) $ 246,124.09
RENEWAL #1 (Step 2, Detailed Design) $ 1,163,648.47 (current)
CONTRACT TOTAL $ 1,409,772.56
A second renewal is planned for the future, costing approximately $670,000.00.
1.2 Reasons additional goods/services could not be foreseen:
Contract renewal was planned.
1.3 Reason other procurement processes are not used:
The funding provided by this contract renewal is for continuation of the existing work of the contract. In so much as work was planned for and anticipated within the original procurement, it is not reasonable or cost effective to undertake a new procurement to acquire these services.
1.4 How cost of renewal was determined:
A cost proposal was provided by Andover Associates, Ltd., and was reviewed by the Division of Sewerage and Drainage and was deemed acceptable.
2. PROJECT TIMELINE: The renewal will allow for 2 years from Notice to Proceed through the completion of the Conform to Contract (CTC) Documents
3. CONTRACT COMPLIANCE No.: 51-0556580 | F1 | Exp. 7/31/2020 | Vendor # 008980
4. ECONOMIC IMPACT: The SWWTP post aeration process provides dissolved oxygen to the treated wastewater in order to meet the daily minimum dissolved oxygen requirement of 7.0 mg/L set forth in the Plant’s NPDES permit. As the aeration diffuser legs fail, it becomes more likely that the plant will have a permit violation due to the lack of oxygen delivered to the treated wastewater. This project will replace all of the post aeration diffusers and piping to ensure that the Plant’s permit is not violated. In addition to the diffuser legs, we will replace two of the centrifugal blowers with more energy efficient hybrid blowers. These blowers will be paired with dissolved oxygen controls and automated valves to reduce energy usage in the post aeration system.
5. FISCAL IMPACT: This legislation authorizes the transfer of $634,048.47 and expenditure of $1,163,648.47 from the Sanitary Sewer General Obligation Bond Fund 6109, and amends the 2019 Capital Improvement Budget to provide sufficient authority.
