More than 2,000 gas stations operate across Israel, serving millions of vehicles every year. Their services are essential, but their operation also creates environmental challenges. Each station generates waste that can release pollutants and hazardous substances if it is not handled correctly. Waste removal and hazardous-material handling at gas stations are subject to regulatory requirements.
Soil Contamination
Fuel-related soil contamination is widespread in Israel, and some of the substances involved are classified as hazardous. Around 300 gas stations are situated in hydrologically sensitive areas, close to groundwater reservoirs or coastlines.
Routine activity generates waste that must be removed promptly and correctly to prevent contamination and exposure to toxic or hazardous substances. Pollutants released from a station can spread hundreds of metres.
Groundwater Contamination: Why Does It Happen?
Pollutants released from gas stations can penetrate groundwater. Such contamination can affect the public through drinking water, produce grown in contaminated soil and inhalation of pollutant vapours.
Inadequate infrastructure for preventing leaks is one cause of groundwater contamination. Poor operation, defective drainage channels and faulty underground infrastructure can also contribute.
Safety: Preventing Harm
Late or improper waste removal can harm both the public and the gas station itself. Gas stations are subject to inspection and enforcement, and failures in the handling of fuels and wastewater may lead to claims or administrative consequences.
Careful wastewater treatment and timely waste removal help reduce environmental, health and operational risks.
Key Maintenance Measures
An important task is maintaining the oil-fuel separator. This unit separates and filters liquids before the treated stream enters the local sewerage system. Oils retained in the tank must be pumped out and transported to appropriate recycling or treatment facilities.
Separators require regular cleaning and thorough maintenance to remain effective. Other maintenance measures include cleaning drainage channels and collectors, repairing separators, washing and unblocking sewer lines, emptying collection pits and pumping chambers and tanks.
Some problems require engineering solutions and entry into sewer chambers by trained professionals using suitable protective equipment and the required safety procedures.
