Present Land Use
The area north of the site is generally reserved for recreational uses; farther north is a southern CA Edison easement, north of the site is a land sublet by LACSD to a nursery, Rosemead blvd is directly east of the site, south of the site is an area of OS, the Rio Hondo Channel extends Northwest and runs immediately west of the site, and the San Gabriel River is southeast of the site.

Document Description
The district is proposing to supply approx 72 acre feet per year (0.06 M gallons per day) of treated wastewater to San Gabriel Valley Water Company for non-potable uses, primarily including landscape irrigation. The district currently discharge approx 6.12 mgd (10 year average from 2007 to 2016) to either the Rio Hondo or the San Gabriel River from Whittier Narrows Water Reclamation Plan from three different points of discharge (no. 011, 002, 004). The discharged recycled water flow to all three discharge points is used for groundwater recharge through percolation within either the Rio Hondo or San Gabriel River or connected spreading basins. The proposed project would reduce WNWRP treated wastewater discharges by approx 1.1 % (0.06 mgd of the 6.12 mgd), equivalent to 72 afy from the over 7,000 afy produced. Approx 27% of the 72 AFY would be reduced from the San Gabriel River discharges; 73 % from the Rio Hondo watershed.
