Deep Well Injection: T.I.R.E.

The City of Los Angeles and Terralog Technologies in collaboration with the U.S. Environmental Protection Agency and with research support from the U.S. Department of Energy and the National Science Foundation has embarked on an innovative technology to inject biosolids deep below the geological subsurface at its Terminal Island Water Reclamation Plant (TIWRP). The Terminal Island Renewable Energy Project known at TIRE, the first of its kind in the nation has been in operation for over two-years. The TIRE, which is being demonstrated under a U.S. EPA five-year permit places biosolids in depleted deep subsurface oil and gas formations where the earth’s high temperature would biodegrade the organic compounds to generate methane gas that can ultimately be used to produce an environmentally safe renewable energy, while the carbon dioxide is sequestered. Three wells have been drilled to a depth of approximately 5300 feet beneath the TIWRP. So far, TIRE has successfully injected over 50 million gallons of bio-slurry material, which includes, brine, treated effluent, digested sludge and re-slurried biosolids. Currently all 50 tons of biosolids produced at TIWRP is being managed at the TIRE facility and up to 150 tons from the Hyperion Treatment Plant.. The injection well is accepting the material and formation response is good. The operations are continuously monitored daily and data is reported to the U. S. EPA and a Technical Advisory Committee.

To ensure that the interested parties and public are engaged and informed about the TIRE project, the City provides presentations, tours and project updates. The first presentation was held in 2001 where over 43 participants attended. To date over 100 presentations and more than 3000 people updates have been provided.
