    Guidelines for Proper Discharge of Chlorinated Water   

Pools, hot tubs, and spas are traditionally disinfected with chlorine or bromine, chemicals which can harm the environment when discharged in high concentrations. In order to protect the environment, please do one or more of the following steps before discharging disinfected water:

1. Test chemical levels to ensure that they are low.
2. Let the water stand untreated until the disinfectant concentration dissipates.
3. Put a dechlorination tablet in the water to reduce residual chlorine concentrations.
4. Release the water over a well-vegetated area on the pool-owner’s property. The vegetation and soil will consume the disinfectant and aerate the water. The longer the vegetated path on the pool-owner’s property, the lower the disinfectant concentration will be when the water leaves the property.


What can I do to prevent storm water pollution?

Everyone can help keep the City of Olmos Park clean. Here are a few tips that can help protect our environment:

  • Don't put anything in storm drains but rainwater.  Storm drains and flood control channels carry surface runoff directly to streams and rivers without treatment. Make sure that runoff carries only rainwater.
  • Avoid throwing litter into the street. Trash-laden gutters increase neighbor-hood pollution and clog storm drains causing street flooding and traffic congestion.
  • Pick up after your pet. Animal waste, when left on the ground, washes down storm drains and contaminates beaches. Picking up dog waste is a City ordinance (Section 3.25) and dog owners disregarding this law may be fined.
  • Recycle your motor oil. There are many gas stations, auto parts stores and repair shops that will collect and recycle used motor oil.
  • Bag, compost or recycle grass, tree limbs, leaves and other yard waste. Soggy yard waste is a major contributor to clogged storm drains and street and neighborhood flooding.
  • Don't use harsh, abrasive or toxic chemicals around the house. Select water-based products over solvent-based products when available (e.g. paint, glue, shoe polish). Also, avoid aerosol sprays; choose a pump spray or other alternatives.
  • Report illegal dumping. To report illegal dumping anytime, day or night, call the City Engineer’s Storm Water Compliance Specialist (210) 342-3991 x203 or the Olmos Park Police Dispatcher (210) 822-2000.
  • Keep sanitation workers safe. When thrown in with the regular trash, household hazardous waste can injure sanitation workers. In addition, landfills are not intended or permitted for those types of wastes, which could impact groundwater.  Call the City Engineer’s Compliance Specialist to find out how to properly dispose of these materials.
  • Be smart when you apply pesticides or fertilizers. Do not apply pesticides or fertilizers before it rains. Not only will you lose most of the chemicals through runoff, but you will also be harming the environment. Do not over-water after application. Read the label and do not apply more than recommended.
Don' get fined! The illegal dumping of hazardous waste carries a minimum fine of $500 per day per violation up to $5,000 per day per violation up to $5,000 per day per violation.
