There are four water supply sources in place to meet the irrigation and drinking water demands of residents of the City of Marco Island.
Source Water Facility
You can find the first water supply located North of US-41 on Collier Blvd. This 205-acre site contains two lakes and is known as Source Water Facility (SWF). The lakes connect to Henderson Creek which runs on the east side of the property. Around 90 percent of the water enters the lakes through sidewall infiltration between the creeks and lakes. This water supply serves about three-quarters of the City of Marco Island’s potable water.
Aquifer Storage Recovery
There are seven Aquifer Storage and Recovery wells near the SWF. These wells let the city store fresh water underground at around 750 feet below grade. The wellfield storage zone is in between two clay layers. Extra flow needed to meet resident’s demands comes from recovering water in the ASR wells.
Brackish Raw Water Supply
This water might seem gross, but it’s treated through reverse osmosis, so it’s incredibly pure. This facility uses water from a Mid-Hawthorn aquifer brackish wellfield that has 15 operational wells.
Reclaimed Water
The City of Marco Island also has a Reclaimed Water Production Facility. Our reclaimed water exceeds the minimum regulations for public access water. This water is continuously monitored, sampled and analyzed by licensed professionals to make sure that the water exceeds the standards required by law.
