CASE STUDY: Headworks
For many years, the unified City-Parish Department of Public Works in Baton Rouge, La., has undertaken monumental capital improvements to expand its wastewater collection and treatment infrastructure. Following decommission of one WWTP and diversion of flows to an expanded and upgraded South Plant (SWWTP), the City-Parish estimated that more than $36 million per year will be saved in future long-term capital and operational costs.
In order to handle the increased capacities, several segments of the SWWTP required significant overhaul and expansion, accomplished in three major improvement projects. The second of these projects includes a new 205 MGD preliminary treatment system. Grit removal is a necessary investment for the plant in order to protect the downstream equipment from abrasion. With a history of sanitary sewer overflows and build-up in its primary settling tanks from poor performing headworks, reliable performance over a range of daily flows and surge events was essential. Specifications called for removal efficiencies of 95 percent.
