maximum influent capacity of 6 MGD. Wastewater is treated to a secondary to Title 22
standards depending upon the ultimate use of the effluent. In 2010, 4,220 acre-feet of
secondary treated effluent is disposed via the SOCWA Effluent Transmission Main to the
Aliso Creek Ocean Outfall and 430 acre-feet of effluent is treated to a tertiary level
meeting Title 22 standards and is sent to the recycled water distribution system.
SMWD Chiquita Water Reclamation Plant - Chiquita Water Reclamation Plant (CWRP)
is operated by Santa Margarita Water District and is located in Chiquita Canyon.
Wastewater is treated to a tertiary level with recycled water treated to Title 22 standards.
CWRP has a maximum design capacity of 8 MGD with plans to increase its size to 10
MGD by 2025. In 2010, approximately 2,511 acre-feet was recycled, with the majority of
the effluent, 7,569 acre-feet, disposed via the Chiquita Land Outfall with a connection to

SMWD Oso Creek Water Reclamation Plant - Oso Creek Water Reclamation Plant
(OCWRP) is located along Oso Creek and is operated by Santa Margarita Water District.
At this facility, wastewater is treated to a secondary level with recycled water treated to
Title 22 standards. A bypass facility allows for excess wastewater to be sent to the
previously discussed J.B. Latham Treatment Plant as OCWRP has no outfalls. Without
the ability to discharge treated effluent, excess flows beyond recycled water demands are
required to be sent to J.B. Latham Treatment Plant. OCWRP has a maximum design
capacity of 3 MGD. In 2010, approximately 1,496 acre-feet, is treated and recycled.
OCWRP is a clipping plant that removes wastewater from the main sewer trunk line.
SMWD Nichols Institute Water Reclamation Plant - The Nichols Institute Water
Reclamation Plant is operated by Santa Margarita Water District and owned by a private
company that owns property within SMWD’s boundaries. This small facility treats
approximately 34 AFY. No outfall is available for this facility. Therefore, all wastewater
is treated to Title 22 standards for recycling purposes. Since this facility is remote from
the existing water and wastewater facilities, SMWD is not obligated to provide an
alternate source of water in the even the Nichols facility becomes inoperable or unusable.
San Clemente Water Reclamation Plant - The City of San Clemente owns and operates
the San Clemente Water Reclamation Plant located within the city. The San Clemente
Water Reclamation Plant has a design capacity of 7 MGD and treats wastewater to
secondary or tertiary levels dependent upon if the water will be recycled or disposed. In
2010, approximately 900 acre-feet were recycled. Any water in excess of the plant’s
recycling limit is conveyed to the San Juan Creek Ocean Outfall via the San Clemente
Land Outfall. Recycling capacity is currently 2.2 MGD with plans to expand to 4.4
MGD.
