Illegal Dumping

Illegal dumping found in the City of Redlands sewer lines

Construction waste found in the sewer system Construction waste removed from the sewer system

Recently the City of Redlands Collection System workers found construction waste in the sanitary sewer.

The first discovered incident occurred on May 19, 2018. Material, similar to that in the photo above, was blocking the sewer line at Ford Street and South Avenue. This material blocked the sewer system’s flow and caused a sanitary sewer overflow. The crew worked for six hours to clear the blockage and remove all of the material from the sewer to prevent another blockage.

The second discovered incident occurred on August 15 2018, at Maple Avenue and Dearborn Street. The material shown above was found in the sewer line during a routine cleaning. The collection system crew was able to divert potential sanitary sewer overflow by cleaning and collecting all of the material from the line.   

The third discovered incident occurred on August 28 2018, at La Mirada Drive and Wabash Avenue. The material shown above was found in the sewer line during a routine cleaning. The collection system crew was able to divert potential sanitary sewer overflow by cleaning and collecting all of the material from the line.

Construction Waste

What’s the Problem?

Construction sites have the potential to contribute to pollution in the storm drain system and to cause problems for the sewer system.

Material such as concrete, plaster, sand, gravel, wood remnants, sawdust, chemicals, solvents, and other construction debris can make its way into the sewer and storm drain system in various ways.

  • Failure to protect storm drains and gutters
  • Failure to protect sewer drains and cleanouts
  • Failure to protect construction material and debris from wind and rain
  • Washing concrete waste and other solids down the sewer and storm drain system
  • Washing down construction areas
  • Draining chemicals, paints and solvents down the sewer and the storm drain system

 The owner and contractor can be held liable whether the discharge to the sewer or storm drain system is unintentional or intentional.


Discharges of construction waste into the sanitary sewer or the storm drain system are a violation of federal & state laws and county & city ordinances. Homeowners, businesses and property owners may be held responsible and required to pay for clean-up cost and could be subject to fines and legal action.

These types of illegal discharges also harm the environment by polluting our waterways, destroying plants, harming aquatic life, and affecting the water quality of our groundwater and surface waters.

Illegal discharges also contribute to sewer back-ups that lead to expensive plumbing bills, costly clean-up and damage to homes, businesses and private property. Also, taxpayer money is used to pay for city resources when responding to illegal dumping calls.

In some cases, illegal discharges lead to structural damage and explosive situations in the sewer and storm drain system. This type of situation can also cause physical harm to the public and to city workers.
