Irvine Ranch Water District (IRWD) is located in Southern California and operates
sewer collection, domestic and non-potable water distribution systems. The sewer
collection system consists of four main tributary areas feeding the Michelson
Water Reclamation Plan (MWRP). Although there are other sewer collection systems
within IRWD's service area, those flows are diverted to other agencies. MWRP is
IRWD's sole source of recycled water and delivers approximately 12,500 acre-feet
of recycled water per year (approximately 13 million gallons per day) to the
non-potable water distribution system. Although IRWD meets the Regional Water
Quality Control Board's limits for the MWRP total dissolved solids (TDS) the
majority of the time, residential self-regenerative (SR) water softeners could
potentially increase TDS levels enough that IRWD would violate the permitted
levels a majority of the time. This paper discusses IRWD's efforts to better
understand the sources of increased TDS in the sewer collection systems. Includes 3 references, table.
