As Ben Franklin said, “When the well is dry we know the worth of water.”

Supplying water for our communities for the long term takes securing reliable water reserves and creating a strategic plan to manage our most valued resource… water. With planning and strategy that looks 50-100 years down the road, we want to ensure a plentiful and cost-effective water supply now and long into the future.

Planning for The Best Water in Texas has been happening in our community for over 75 years. The San Jacinto River Authority serves the entire San Jacinto River watershed. We conserve and protect the water resources of the San Jacinto River Basin throughout all or part of seven Texas counties including Montgomery, Fort Bend, Waller, Grimes, Walker, San Jacinto, and Liberty.

SUBSIDENCE solutions

Land subsidence occurs when large amounts of groundwater have been excessively withdrawn from an aquifer. SJRA works to find and develop solutions to help our communities avoid subsidence.

What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
