Welcome to our virtual tour of the Donald C. Tillman Water Reclamation Plant. This is the next best thing to taking a live tour at the plant. We hope that you will come out and see us in person. Please call 818-778-4138 to make arrangements.

Sewage contains mostly water and solids. As you go through the tour, notice that many of the treatment processes at the plant are designed to separate solids from water. This must take place so that when the wastewater is completely treated it is clean enough to be pumped into the Los Angeles River or reclaimed for other uses. The solids have value too - they are sent back into the sewer system and flow to the Hyperion Treatment Plant where they are processed into energy resources, soil amendments, and fertilizer.
