Orange County’s Groundwater Basin lies in a coastal alluvial plain in the northwestern portion of the county.
Since most of our water is collected in basins and stored for usage we need to be careful how the “plumbing” of our water system operates. It is important to keep the water free of trash, chemicals, and animals.
Our water in Laguna Niguel is collected with a complex system of dams, reservoirs, power plants, pumping plants, canals, and aqueducts. Some of these systems appear to be failing in my photographs. Erosion of older dams, sewer lines next to water sources at risk from the heavy temporary rains we receive in the late winter, garbage thrown into water storage etc makes our drinking water and oceans at risk.
Aliso Creek newer dams and aeration which were constructed to help reduce the odors from the Aliso Creek at Crown Valley and Niguel Roads. It was suspected that the car wash was the source of the odor and gas smell but car washes actually recycle water and are more efficient use of water than washing your car with the running hose in your driveway. I interviewed the owner of the New Car wash which was held up a long delay in meeting City, State and County regulations.
Photos of man made lake in north west county which holds water to be distributed.
This particular “lake” is used for recreational paddle boats and fishing. I saw a problem with all the vehicles that drive right to the surface of the water ( which we later drink) because dumping of oil from the cars and trash occurs
These slides show the concrete and aggregate rock surface and open drain holes north of the intersection. Safety grates were put over the large storm drains which allow rain to flow in during heavy rainfall and also air in during dry season.
The next slides show the Coastal Water Treatment Plant in Wood Canyon Park. Water flows into the man made lake and is treated with air, churned by turbines and allowed sunlight and released. The plant is also known as the “poop plant” as sewage is cleaned up here.
Water in Laguna Niguel is mostly ground water from the Colorado River transported via aqueduct but also rain water runoff moved from retaining basins that catch the rain. We have infrequent rain in South Orange County and much rainwater is lost when it rains heavily. Better storage and routing needs to be created.
The next slide illustrates an old fashioned water tank which is in use in Santa Ana. The Santa Ana river supplies water to underground tanks in north west Orange County. Water tanks look like they are inefficient but they have been used in Agricultural Communities for centuries.
The following slides show Aliso Creek water from March 1 2009 – May 1 2009. Note the changes in algae levels on days the temperature rose in late April. You can see the water turned muddy and green. Aliso Creek runoff the the ocean is considered one of the highest risks for bacterium and levels of chloroform after heavy rain. Many reasons are speculated why this exists
Signs are posted for the purple recycled water, for keep out during rain storm dangers and to keep persons aware that anything you dump in reservoirs, drains and pipes eventually either gets into the drinking cup at the tap or out to the ocean
