This WWTP project is a good example of Owners, Engineers and Contractors collaborating to manage equipment delays and maintain plant operations while upgrading critical plant infrastructure. The David Hawes WWTP Upgrade project is the result of a larger long term master planning effort initiated by RWRA in 2019 based on a need for more loadings capacity, improve industrial loading management and addition of a Nutrient removal processes. The project need was driven by several factors including aging assets, operational problems stemming from large industrial loadings as well as a need to add capacity for future regional growth, comply with future regulations and fulfill an Agreed Order. RWRA’s David Hawes WWTP Upgrades project consisted of upgrading the Plant’s existing Oxidation ditches to incorporate a new fine bubble aeration system and mixers to convert into a biological nutrient removal system. The oxidation ditch upgrades do not increase the rated flow capacity of the facility. However, it does significantly increase the loadings capacity of the plant, which is critical considering some of the unique industrial flows that this plant receives. The plant upgrades also included upgrading Two (2) existing clarifiers, Construction of a new 45’ Gravity Thickener, Upgrade of an existing Gravity Thickener, New Sludge Holding tanks, Upgrades to existing SH Tanks and construction of a new sludge pump station. The project also included a complete renovation and upgrade of the plants solids dewatering system. Lastly, the plant power feed was upsized and completely replaced with a new service from the local utility supplier along with a revamp of the main switchboard downstream gear. This Project experienced several similar challenges to most existing plant upgrades as well as some unique to the current market that we are all living and working in. Prior to the bidding period on this project, RWRA and Strand identified the new electrical switchboard as a major item with a critical lead time, as such, a decision was made for RWRA to pre-purchase the electrical switchboard package with the goal of avoiding delays. Ultimately this electrical equipment was still the driving factor of completing the project as the equipment continued to be delayed throughout the project. To manage this, significant temporary operations were identified as an option to keep the project on track. RWRA, Strand and D&M worked well together to develop possible management strategies, vet out costs and implement temporary operations which kept the plant in service and reduced the impacts of the Electrical delays from nearly a 1-year impact to only 50 days in contract time extensions.
