Wastewater Treatment Plant Expansion

Current Status:

The City of Kyle is currently designing the next expansion phase for the wastewater treatment plant that will expand the plant's capacity from a permitted average daily flow (ADF) of 4.5 million gallons per day (MGD) to an ADF of 9 MGD. During this next expansion, we will be incorporating equipment and processes that will better address odors. Construction for this expansion is expected to begin within the first quarter of 2025. 

The City of Kyle owns and operates the Kyle Wastewater Treatment Plant (WWTP) which was purchased from Aqua Texas in 2015. The facility is located at 941 New Bridge Drive. Prior to the expansion, the existing plants had a combined rated capacity of 3.0 million gallons per day (MGD). The plant discharges its treated effluent to Plum Creek. The two existing WWTPs were put into operation in 2000 and 2006.  The WWTP saw an average daily flow above 7% of its current rated capacity for over three consecutive months. In response, the City initiated engineering and financial planning for expansion of the plant per Texas Administrative Code (TAC), 30 TAC§305.126(a) and hired Contractor Archer Western Construction, LLC to expand the plant's capacity from a permitted average daily flow (ADF) of 3.0 MGD to an ADF of 4.5 MGD. The total budget for the project was $28, 893,400. The budget was increased to $34,148,594.93 to add a dewatering facility.

The WWTP expansion from 3MGD to 4.5 MGD project included:

• Headworks and Influent Lift Station
• Secondary Treatment Facilities – Aeration Splitter Box, Aeration Basins, Secondary Clarifiers
• Tertiary Treatment Facilities – Aerobic Digesters, UV Disinfection
• New Operations Building
• Modification to existing Lift Station and existing treatment Plant #1 and Plant #2
• Berm Installation – Earthen and Concrete
• New dewatering facility

Timeline:

• March 26, 2020 - Construction Start Date
• June 2023 - New expansion was operational
• July 13, 2023 - The City of Kyle officially cut the ribbon for the expanded Wastewater Treatment Plant
