In order to maintain reliable wastewater treatment to City of Austin customers, Austin Public Works and Austin Water are undertaking a major improvement project within the South Austin Regional Wastewater Treatment Plant. The existing outdoor electrical main 15KV switchgear for the South Austin Regional Wastewater Treatment Plant (SAR WWTP) has underwent deterioration and is in need of replacement.

The existing 15KV switchgear serves predominately the Trains A and B facilities of the plant, as well as areas common to all trains of the plant, such as Lift Station No. 1, Filter Building, Water Reuse, Dechlorination Building, and Administration Building. The gear also presents maintenance concerns. The gear is outdated and its replacement electrical components are difficult to procure or unavailable. Due to the corrosion and deterioration of the gear, the gear also presents a safety concern for electrical maintenance personnel working on the gear.
