Beginning in the 1920s up to the late 1950s, the Redlands “Sewer Farm” (a common term during that time) was located north and west of the City, on the north side of the Santa Ana River, near Alabama Street. Up until this time, an acceptable form of wastewater treatment was the Imhoff Technology. Raw sewage was placed in an Imhoff Tank where solids are separated from the liquid. The solids were then transferred to large drying lagoons, and the liquid portion, without further treatment, was discharged to the Santa Ana River. Due to the Federal Water Pollution Control Act of 1948, it was unlawful for any person to discharge any pollutant to navigable waters.

As a result of these new regulations, the City of Redlands facility was relocated in the early 1960s to the south side of the river at the north end of Nevada Street and a secondary wastewater treatment was constructed. With this method of treatment the wastewater solids are settled in large tanks and then removed, dried and disposed of off-site. The liquid portion is transferred to an activated sludge process where different chambers within this process help remove conventional pollutants. The discharge of the treated wastewater was to be treated in such a degree that disposal to navigable waters or direct disposal to the groundwater table will not endanger public health or degrade groundwater quality. Development of population and water use (i.e., water conservation) have drastically changed the incoming wastewater matrix to treatment plants. Consequently, over the years the City of Redlands has undergone many upgrades to the original wastewater treatment plant.

The Redlands Wastewater Treatment Facility is located on approximately 50 acres. The facility currently employs a staff of 25 on a continuous basis. The City’s wastewater treatment facility has a rated treatment capacity of 9.5 million gallons per day annual dry weather flow. Approximately 6 million gallons of that capacity is in a membrane bioreactor system, the remaining 3.5 million gallons is in a conventional activated sludge process.

The City of Redlands operates a certified environmental laboratory for monitoring its drinking water supply and wastewater effluent. The laboratory is certified by the State Water Resources Control Board under Environmental Laboratory Accreditation Program (ELAP). The laboratory has two objectives: First, the laboratory provides information to the operational staff of the City’s water and wastewater treatment facilities, and sanitary landfill. Second, the laboratory provides monitoring information to the State of California’s environmental regulatory agencies. The laboratory staff is trained in highly technical testing procedures, and uses sophisticated instrumentation, such as ion chromatography and total organic carbon, to perform required laboratory analysis.
