Lago Vista advisory committee discusses irrigation redesign, TCEQ limits and long-term water planning

Members of the Lago Vista Golf Advisory Committee spent a large portion of their meeting discussing a proposed irrigation-system redesign for the municipal golf course, focusing on regulatory limits, system capacity and timing relative to the golfing season.

The discussion centered on the city—s current reclaimed-water permit and practical limits identified during staff analysis. Committee members noted that the Texas Commission on Environmental Quality (TCEQ) gives the city an average allowable application rate that, when averaged over a year, equates to about 413,000 gallons per day. Committee members said the prior irrigation design had capacity close to four times that rate, and that choosing a smaller-capacity system could yield significant cost savings while still meeting regulatory limits and actual annual application patterns.

Committee members and staff emphasized that irrigation need varies widely by season and climate and that peak-night or peak-summer usage is not representative of annual averages. They discussed scenarios in which summer irrigation could be many times higher than the annual average, but that frequent rainy periods mean much lower application the rest of the year. Committee members weighed whether designing for larger future capacity would be prudent or wasteful, given the TCEQ limits and likely alternate uses for added capacity.

Participants described two classifications of reclaimed water in play: "type 2" (the city—s current classification) and "type 1," a higher classification the city could seek via conversion. The committee was told conversion to type 1 would expand irrigation time windows and the places the city could use reclaimed water, but any conversion was likely three to six years away and would depend on when the city elected to invest in upgrades. Speakers also noted differences in water quality between the classes, including higher salts in type 1 water, which could affect turf management decisions.

Committee members identified other potential uses for any additional reclaimed-water capacity beyond the golf course: community ball fields and a Park Owners Association interested in buying water were mentioned. Those future demands figured into the committee—s conclusion that overdesigning the golf course irrigation solely to accommodate a hypothetical type-1 future might not be the best use of funds.

Committee members and golf staff also discussed operational impacts: under the current (type 2) classification, irrigated areas needed to be dry for 24 hours after irrigation before some public events could safely occur; that constraint affects scheduling of fundraisers or movie-on-the-greens events. Staff said bids had not yet been returned; a pre-construction meeting had taken place and the project timeline had been discussed with a possible six-month construction window under typical conditions.

No formal motion or vote on the irrigation design occurred at the meeting. Committee members directed staff and consultants to continue technical work and stressed the importance of coordinating engineering, budgeting and golf-professional input so the city intentionally balances cost savings with playability and event use.

Questions raised at the meeting that will require follow-up included final bid amounts, a precise timeline for any type-2 to type-1 conversion, and whether the city will pursue alternative allocations of reclaimed water if conversion proceeds.

Ending: Committee members said they were encouraged by preliminary numbers suggesting the city could reduce costs while meeting course needs and regulatory limits; they asked staff to keep them informed as bids and regulatory steps progress.
