Raw sewage has been bubbling up through manholes on streets all over Collier County — even covering a section of Mahogany Bend Drive in Fiddler’s Creek with thick waste.
A combination of flooding from Irma and no power at almost all of the county’s 800 pump stations has caused sewage to back up into streets, homes and businesses instead of being pumped to sewage treatment plants.
“It’s happening everywhere,” county spokeswoman

This resource presents the key components of a wastewater collection system, reasons why flow monitoring in the system is important.
Infiltration/Inflow (I/I) causes dilution in sanitary sewers. Dilution of sewage decreases the efficiency of treatment, and may cause sewage volumes to exceed design capacity. Although inflow is technically different from infiltration, it may be difficult to determine which is causing dilution problems in inaccessible sewers. The United States Environmental Protection Agency defines the term infiltration/inflow as combined contributions from both.
This video shows how the Decentralised Wastewater Treatment System (DEWATS) works. It is a simple and proven technology to treat organic wastewater.
Since it requires no electricity and only little maintenance it can be used to provide marginalized communities with wastewater treatment.
The decentralised wastewater treatment system (DEWATS) is a simple design, non-dependent on energy, reliable, long-lasting, tolerant towards inflow fluctuation, and low in costs. It can treat organic wastewater from domestic and industrial sources. DEWATS is based on different natural water treatment techniques which are combined according to requirements such as the characteristics of wastewater, desired effluent quality and technical specifications.
The CDD Society is an Indian NGO committed to providing marginalised people with access to water, sanitation and energy. From its headquarters in Bangalore, it works through a network of likeminded organisations across South Asia to provide cost effective, environmentally sound, and community specific basic needs services.
