The LBRID Sewer collection system consists of the pipe system and lift stations responsible for conveying raw sewage and wastewater from homes to the District’s Treatment and Disposal System. The pipe network contains ~ 35,000 ft of mostly vitrified clay pipe of varying diameter, 149 manholes, and five lift stations.
There are five lift stations used to pump sewage and wastewater to the treatment, storage and disposal facility. Four of the five were last rehabilitated/upgraded in 2017 using approximately $1.2M in funds from a $6M grant from the Clean Water State Revolving Fund. The fifth lift station was last serviced in 2020.
Sewer Treatment, Storage, and Disposal
Eight (8) earthen ponds with a capacity nearing 27 MG make up the treatment and storage facilities and 15+ acres of native grassland make up the land application area used for disposal of treated sewage and wastewater for the District.
Treatment occurs when raw sewage from the main sewage collection tank located at the water treatment facility is pumped to pond 1 where through facultative processes, treatment begins. Treatment continues as the water flows sequentially through ponds 2 and 3. After Pond 3, the water flows into pond 4, where final treatment occurs.
From pond 4, water is pumped to pond 7 and pond 8, where it can then be disinfected and held in a chlorine contact chamber before it is then pumped to the sprayfields.
Pond 5 and Pond 6 are considered overflow ponds when storage capacity has been reached in the other ponds.
