CIP Status Update

 April 2025

North of River Sanitary District sewer pipelines convey raw sewage from your residence or business to the wastewater treatment plant.

·         “Rags” are an accumulation of “baby wipes”, flushable wipes, clothing, towels, etc.  They tend to bind up into “rag monsters” and settle out in the sewer pipelines.

·         District Staff expend great effort to remove these accumulations, allowing free flow of sewage to the wastewater treatment plant.

Please keep all “rags” out of the sewer.  They are not meant to be flushed down the toilet.

North of River Sanitary District has been repairing deteriorated sewer pipeline manholes along Seventh Standard Road.

  • The pipeline was constructed in the early 1990s, and the wastewater has caused deterioration of the concrete manhole structures.
  • Rehabilitation includes a combination of fiberglass manhole inserts, cured in place polyurethane liners, epoxy coatings, and corrosion resistant manhole covers.

North of River Sanitary District is currently designing an upgrade and expansion to the Wastewater Treatment Plant.  Growth within the NORSD’s sphere of influence and within the City of Shafter necessitate the need for additional treatment capacity.  Currently projections are that construction will commence in 2026.

 

  • Treatment capacity would increase from 7.5 million gallons average daily flow to 10.
  •  Secondary process will be converted from a trickling filter to a membrane bioreactor.  Allowing for denitrification of the wastewater.
