Georgetown staff, water board and council favor membrane bioreactor for Northlands plant to meet tighter phosphorus limits
Summary
Staff presented two treatment alternatives for the new Northlands wastewater facility (CAS with later conversion vs. membrane bioreactor). After a pairwise evaluation and a unanimous Water Board recommendation, council members signaled concurrence with selecting an MBR to future-proof performance despite higher upfront costs.
City staff and the project consultant presented two treatment alternatives for the proposed Northlands wastewater treatment plant and reported a staff and Water Board recommendation to construct a membrane bioreactor (MBR) facility.
Coby Gee, project manager for Northlands with consultant Freese and Nichols, described the project as a 1.5–3.0 million gallons-per-day (MGD) wastewater treatment facility located adjacent to Sun City. He said the city is currently permitted to discharge up to 3.0 MGD to Jennings Branch (downstream into Cowan Creek and the San Gabriel River) and that the critical design constraint for the plant is the total-phosphorus permit limit, currently 0.5 milligrams per liter.
Staff explained the two shortlisted options: a conventional activated-sludge (CAS) plant with biological nutrient removal and a membrane bioreactor (MBR) with biological nutrient removal. Both…
