San Marcos Bulk Water Delivery — Serving the Heart of the I-35 Corridor

San Marcos is one of the fastest-growing cities in Texas. Texas State University drives a constant cycle of new construction, renovation, and development. The I-35 corridor through Hays County is one of the most active building markets in the state. And beyond the city limits, rural properties along the San Marcos River and throughout the surrounding area depend on wells, storage tanks, and hauled water to stay operational. Weeping Willow Water Supply has been serving San Marcos and the surrounding region since 2018 — and we know what reliable bulk water delivery looks like in a market that moves this fast.

We haul bulk water to homes, ranches, job sites, student housing developments, and commercial properties throughout San Marcos and Hays County. One-time deliveries, recurring construction schedules, emergency fills — we handle all of it. Call or text, tell us what you need, and we’ll get it on the schedule.

What We Deliver in San Marcos

Construction water is one of our highest-demand services in San Marcos. With new residential developments, student housing projects, and commercial construction active across the city and surrounding county, job sites need water for soil compaction, dust control, concrete mixing, and site preparation on a consistent schedule. We work directly with builders, general contractors, and site supervisors to make sure water shows up when the crew needs it.

Pool fills are a steady request in San Marcos — from new construction pools in growing subdivisions to older pools being refilled after repairs or seasonal drains. We fill most residential pools in one or two loads depending on size. Fast, clean, and done without waiting days for a garden hose to do the job.

Storage tank fills serve rural properties south and east of San Marcos that rely on wells or rainwater collection as their primary water source. When wells run low during dry summers or tanks need topping off between rains, we deliver directly to your tank — 2,500 gallons, 5,000 gallons, or larger systems — using 2″ or 3″ hoses for a fast, efficient fill.

Emergency water delivery is available most days with same-day or next-day service. Well failures, unexpected outages, and supply interruptions don’t wait for a convenient window. Call or text us and we’ll get you on the schedule and keep things running.
