Deadline extended to submit Central Florida Water Initiative supply project options

The Central Florida Water Initiative (CFWI) is working collaboratively with the region’s utilities, water users and local stakeholders to identify water supply project options to help meet our water supply needs, now and in the future. One piece of this effort is the creation a new list of potential projects to meet water users’ needs, which will be included in the upcoming 2020 CFWI Regional Water Supply Plan.

In March, the water management districts and the Florida Department of Environmental Protection (DEP) formed a new CFWI work group dedicated to developing regional water supply project options. This group is made up of engineers, planners, and scientists from the water management districts, DEP, local governments and other area stakeholders. As part of this effort, the districts are currently reaching out to stakeholders in the Central Florida region to help develop ideas and concepts for new potential water supply, water resource development and water conservation project options.

Creating a list of potential water supply projects is a collaborative process and is based on voluntary input from area stakeholders. The districts are particularly focusing on identifying potential projects that achieve water conservation, provide reclaimed water to new water users, develop alternative water supplies, or benefit natural systems. Organizations or individuals which would like to submit a project option or concept for consideration in the Central Florida Regional Water Supply Plan are encouraged to contact their respective water management district representative listed below.

Potential project options can be submitted via mail or email. The Districts request that any responses be submitted by April 1, 2019, so that they can be considered for the 2020 Regional Water Supply Plan. A link to a project option form is provided below.

Once-a-week watering restrictions begin Nov. 4th

Mandatory lawn watering restrictions specify the days when you may water. These days depend on whether you have an odd- or even-numbered address, and the time of year. Per County ordinance, the following restrictions apply to landscape irrigation regardless of whether the water comes from groundwater or surface water, from a private well or pump, or from a public or private utility:

  • Outdoor irrigation is limited to one day a week during Eastern Standard Time (from the first Sunday in November until the second Sunday in March) and two days a week during Daylight Saving Time (from the second Sunday in March until the first Sunday in November).

Watershed groups have a positive impact on local water quality, study finds

Economists have found that in the United States, watershed groups have had a positive impact on their local water quality.

A new published in the journal Proceedings of the National Academy of Sciences provides the first empirical evidence that nonprofit organizations can provide public goods, said Christian Langpap, an Oregon State University economist and study co-author with Laura Grant, an assistant professor of economics at Claremont McKenna College.

In economics, a public good is a commodity or service that individuals cannot be effectively excluded from using, and where use by one individual does not reduce availability to others. For these reasons, public goods can't be provided for profit and nonprofits can play an important role.

"Environmental nonprofit groups are assumed to provide public goods," said Langpap, an associate professor in OSU's College of Agricultural Sciences. "But until now that assumption has never been tested empirically. We determined that the presence of water groups in a watershed resulted in improved water quality and higher proportions of swimmable and fishable water bodies."

The presence and activity of watershed groups can impact water quality in various ways, including oversight and monitoring, direct actions such as organizing volunteers for cleanups or restoration, and indirect actions like advocacy and education.

The researchers' analysis combined data on water quality and watershed groups for 2,150 watersheds in the continental United States from 1996 to 2008. The number of watershed groups across the lower 48 tripled during this period, from 500 to 1,500.
