About The Quad’s drain & sewer lines
The Quad opened in 1953 as one of the region’s early shopping centers and added a three-story May Company store in 1965. The 1987 Whittier Narrows earthquake collapsed its parking structure, and the center was largely rebuilt in the years that followed; a medical plaza now occupies part of the former department-store site. Today it’s a large open-air retail center with roughly 430,000 square feet of space and a mix of national retailers and sit-down restaurants.
The blocks around The Quad combine that commercial activity with established residential streets. Restaurant kitchens produce grease, medical and retail restrooms see heavy paper use (and the occasional wipe that shouldn’t be there), and nearby homes have the aging laterals typical of mid-century Whittier.

For businesses near Whittier Boulevard & Painter
- Restaurants: pair interceptor pumping with periodic line jetting; grease that never reaches the interceptor still hardens in the pipe.
- Medical offices: post clear signage in restrooms about what can be flushed — wipes, gloves and paper towels are frequent causes of restroom main backups.
- Property managers: keep a map of cleanouts and a log of which tenants’ lines have been cleaned; it speeds up emergencies dramatically.
For homeowners nearby
The residential streets near The Quad are inside Whittier city limits, so the City maintains the public main and owners maintain their laterals. If your main backs up, check your exterior cleanout: if it’s full of water and neighbors are affected too, call City Public Works; otherwise, the problem is most likely in your lateral.
Medical and office restrooms
Medical offices, clinics and professional suites around The Quad share a particular drain problem: high restroom traffic and products that should never be flushed — gloves, paper towels, wipes and hygiene products. These snag at joints and build into blockages in restroom branch lines and building mains. Clear signage, covered waste bins in every stall, and periodic jetting of the restroom mains keep these lines from becoming a recurring disruption for patients and staff.
