Shashi has 40 years of experience in water and wastewater engineering. His experience as a core designer includes a wide range of projects including lift stations, oxidation ditches, sequencing batch reactors, clarifiers, screening facilities, headworks, odor control, chemical feed equipment and chemical storage equipment among other projects.

​

He has spent his career working across the country on projects both large and small. His primary locations include Texas, Arizona, California, Kansas and currently Sioux Falls. While in Texas, he has worked as a chief engineer for water and wastewater infrastructure at the Lower Valley Water District in El Paso, TX. The scope of projects included the construction of 8 lift stations, 20 miles of water and sewer lines, storage towers and a booster station. He also designed a 40 million gallon per day return activated sludge system for the Haskell Street Wastewater Facility.

​

While working in Arizona, Mr. Prasad designed headworks for the 91st Avenue plant in Phoenix. The system involved flow distribution bays, flow meters and sluice gates for the 150 million gallon per day facility. He also designed drinking water storage and pumping systems for the Union Hills Water Treatment Plant. The plant utilized a 180 million gallon storage basin and 60-inch diameter screw pumps to transfer up to 60 million gallons per day.

​

His experience in California includes a return activated sludge pumping system for the Hyperion Wastewater Plant in Los Angeles which had a capacity of 450 million gallons per day. The design utilized 94-inch screw pumps. He also designed the headworks, bar screens and odor control for the San Clemente wastewater facility.

 

Mr. Prasad has experience working with multiple subcontractors from many

disciplines including electrical, mechanical, HVAC and SCADA controls. He has

worked for nationally renowned companies including Black and Veatch Inc., Metcalf and Eddy Inc., RBF Consulting Inc. and Carollo Engineers, Inc. Shashi Focuses on designing facilities that are easy to maintain and that will last for many years to come.

RELEVANT EXPERIENCE

• Brandon, SD - This project included the design of Brandon lift station to pump all sewage generate at Brandon to the City of Sioux Falls wastewater treatment plant using dry pit large 150 HP VFD pumps. The pump station has wet-well/dry-well set up. The lift station is rated to pump 4.4 mgd.

• Brandon, SD – The lift station has been designed with odor scrubber. The odor scrubber may be required in summer months. The scrubber is a dry carbon media.

• Burbank, CA – The Valley Pumping Plant is the 10 mgd forebay (finished water storage) with disinfection and booster pumps. The project included the lining of the forebay, design of chlorine and anhydrous ammonia injection and refurbishing of the pumps.

• Burbank, CA - This project included the design of chlorine scrubber for the ton cylinders at the Valley Pumping plant at Burbank, CA.

• City of Missouri, TX - This project included the design of Sludge thickening clarifiers and dewatering using a 2 meter belt filter press, and polymer feed system and conveyor for truck loadings.

• El Paso, TX - This project included the design of 30 mgd advanced (oxygen/tertiary) treatment with clarifiers, automatic back wash filters, aerobic sludge digesters with coarse bubble diffusers.
