Describes the Larkin Groups work with produced water and other forms of water reclamation.

 Water Reclamation

Creative approaches to water management offer communities a secure source of water.

Produced Water Production

The Larkin Group is working in conjunction with engineering groups and water specialists to design systems to use produced water – water brought up as part of the oil drilling process – as a source of operations, irrigation and potentially, drinking water.

Produced water comes from enormous bodies of water deep in the earth, located under the aquifers we now use. Instead of just re-injecting the produced water back into the Monterey Formation, we are investigating the most effective cleaning methods that will provide a much-needed addition to our stressed water supply.

This technology is currently being used in the Central Valley of California for agriculture, viticulture, and support of aquifers and species. Arroyo Grande is using it to enhance the Pismo Creek steelhead trout fishery.

Vandenberg Plan - Produced Water

Supplying sufficient water to the planned Vandenberg Dunes resort project on Vandenberg Space Force Base was always the greatest challenge. Through the course of the project Larkin Group Sustainable Solutions had to repeatedly adjust to changing conditions and rapidly strategize effective new water sources.

Our most recent proposal would have used cleaned produced water (oil water) from Sentinel Peak Resources rigs located just off Vandenberg and routed it to the golf course project for irrigation.

We are currently testing the latest technologies to clean produced water to high quality standards so that it meets environmental regulations for beneficial reuse. Our testing has included:

  • Running 7 pilots over the last 3 years

  • Last 5 successful pilots run in conjunction with Global Water Innovations

  • Batch testing of impaired waters at multiple sites

  • Working with multiple research groups

  • Working with Santa Barbara County Supervisors, SBC Water Resources Division, SBC Public Works Dept., and Municipal Community Service Districts

Wastewater Conversion

The Larkin Group has been working with MNS Engineers to develop plans to treat human wastewater more efficiently. The Cloacina stainless steel package wastewater treatment plants convert human wastewater through a reverse osmosis treatment plant with proven and licensed technology.

The Larkin Group tested using hydrodynamic cavitation (developed at the Codiga Resource Recovery Center at Stanford University) to increase the efficiency of their MBR system to reduce operating & management expenses. Unfortunately this method proved unsuccessful.

The focus of The Larkin Group’s work is to lower the overall cost, energy use, footprint, and chemical additives necessary to treat municipal wastewater and we continue to research the latest technologies.
