What is the minimum thickness for reclaimed water storage lake liner?
The minimum thickness for a reclaimed water storage lake liner is 60 mils for a High Density Polyethylene (HDPE) liner. Other liner thicknesses and material of construction may be considered if it can be demonstrated that the proposed liner will meet the best available demonstrated control technology (BADCT) requirements for Aquifer Protection Permits.

Liners are only required for lakes storing Class A, B and C reclaimed water. However, liners are usually installed on all storage lakes to minimize loss of reclaimed water from the lake due to percolation. For more information, please email treatmentplantprogram@maricopa.gov.
