Item 4C Item 4C Approve an annual purchase agreement for providing odor control treatment at City wastewater lift stations with Premier Magnesia, LLC. in an amount not to exceed $140,000 for a 12-month period Good evening Honorable Mayor and members of the City Council. This is Cristina McMurray, Deputy Director for Public Works, and I will be presenting an annual agreement for City wastewater lift stations for your consideration. 1 Requested Action Approve an annual purchase agreement for providing odor control treatment at City wastewater lift stations with Premier Magnesia, LLC. in an amount not to exceed $140,000 for a 12-month period Staff requests that City Council: Approve an annual purchase agreement for providing odor control treatment at City wastewater lift stations with Premier Magnesia, LLC. in an amount not to exceed $140,000 for a 12-month period 2 Thioguard Treatment at Lift Stations Shady Lane Lift Station Lonesome Dove Lift Station The City pre-treats the wastewater flows at the Shady Lane and Lonesome Dove wastewater lift stations before it flows to the Trinity River Authority (TRA) treatment plant. These two lift stations are the largest in the City and handle the largest volume of wastewater flows. 3 Thioguard Treatment at Lift Stations Reasons to pretreat wastewater with Thioguard: Manage hydrogen sulfide gas Odor control Maintain integrity of infrastructure Thioguard Tank at Shady Lane Lift Station It is necessary for the City to pre-treat the wastewater to manage the effects of hydrogen sulfide gas in the sewer system. Hydrogen sulfide gas has a very strong “rotten egg” odor. Treating with Thioguard provides odor control that would otherwise have an impact on residents. Hydrogen sulfide gas is also highly corrosive to concrete manholes and the cast iron manhole ring and lid. Pre-treatment with Thioguard aids in the reduction of hydrogen sulfide gas in order to maintain the integrity of wastewater infrastructure. 4 Thioguard Treatment at Lift Stations Reasons to pretreat with Thioguard (Cont’d): Prevent grease buildup Manage TRA treatment costs Thioguard Tank at Lonesome Dove Lift Station Other benefits of the Thioguard technology include the prevention of grease buildup in the wastewater lift station wet-wells and downstream sewer mains eliminating the need for City crews to remove and dispose of excess grease. Grease causes blockage in the mains that may lead to potential sewer overflows and Texas Commission on Environmental Quality (TCEQ) fines. TRA also charges the City a surcharge for high levels of BOD (Biochemical Oxygen Demand) attributed to grease in the wastewater flows. 5 Thioguard Treatment at Lift Stations FY 2017 Increase in Thioguard dosing due to: Large number of new restaurants Increase in grease and BOD in wastewater flows This year it has been necessary for the City to increase the Thioguard dosing by an additional 5-10 gallons per day at the Shady Lane Lift Station bringing the combined daily total for both lift stations to 125 gallons per day. The necessary increase in the Thioguard dosing is due to the increase in the number of new restaurants in the City, and the subsequent increase in grease and BOD in wastewater flows. This increase will cost the City approximately $10,000 more per year in pre-treatment costs. It should be noted, that the Thioguard dosing may need to be increased as more restaurants open in the City. 6 Financial Considerations: FY 2017 Public Works Budget Price increase from $2.73/gal to $2.77/gal Premier Magnesia is Sole Source provider Thioguard Treatment at Lift Stations Funding for Thioguard treatment at the City’s wastewater lift stations is provided in the annual Public Works Wastewater Operating Budget. Under the proposed agreement, the cost per gallon will increase from $2.73 per gallon to $2.77 per gallon for the upcoming year. Premier Magnesia is a sole source provider for Thioguard. Premier Magnesia has been providing Thioguard for Southlake and the Trinity River Authority since 2006 because previous attempts to control the hydrogen sulfide with other products were not successful. 7 City of Southlake Strategy Map The City of Southlake provides municipal services that support the highest quality of life for our residents, businesses, and visitors.
