Laguna Madre Water District FY 2010 WaterSMART Grant to Reuse Wastewater.

Mr. David H. Flinn, PE is the engineer responsible for development of this successful grant project. Mr. Flinn worked with the District to develop a project to treat the wastewater effluent from the District's three plants to tertiary levels for unrestricted use. The plan included cost for the additional treatment, storage and distribution to potential customers. All of the available wastewater effluent would be reused as possible. The project scope has been reduced from $6,000,000 to $1,500,000 limited to the Laguna Vista Wastewater Treatment Plant due to budget constraints. The project is currently about to begin the design stage.

2004 Madeira Development Water Alternatives Study for a 1,400 Acre Tract in Cameron County.

Mr. David H. Flinn was the Engineer primarily responsible for this study that compared alternatives for water supply to this tract to be developed. The tract lies within the East Rio Hondo Water Supply Corporation (ERHWSC) CCN, but is close to VMUD No. 2 and the Brownsville Public Utilities Board facilities. A projection of ultimate water demand needed to supply the tract from each entity was evaluated. The evaluation included development on an on-site groundwater reverse osmosis plant.  The economy placed the project on hold.
