What we do
Supply, storage and distribution, designed around the source, growth and budget.
We design the water side of Texas development and of small public systems: wells, treatment, storage tanks, booster and fire flow pump stations, and the mains that connect a site to its provider. Developers bring us in for a subdivision or a commercial site. Utilities and towns bring us in to study an existing system and plan what to fix first.
A main at the property line does not prove the system can serve you. Before the layout is fixed, we find out who holds the right to serve the land, what the provider can commit and what fire flow the fire code official will require. Certificates of convenience and necessity (CCNs) from the Public Utility Commission of Texas set the service areas. Where a groundwater conservation district exists, it sets the rules for a new well. Our findings tell you what is likely. Only the utility’s own commitment binds it.
TCEQ regulates public water systems under 30 TAC Chapter 290. A system with 15 or more connections, or one that serves 25 or more people at least 60 days a year, is a public water system, and a new one needs written TCEQ approval of its plans before construction. The rules call for at least 35 psi at 1.5 gallons per minute per connection, and 20 psi during fire flow where the system provides fire protection. See public water system design in Texas.
To start, send the site location, the planned use, the number of lots or connections, and any letters you already have from the utility.
Bring us in before you close on land or fix the site plan, when a utility says the line is full, or when a system loses more water than it bills. For design detail, see water distribution and pump and lift stations. Outside Texas, see water engineering in Colorado, Oklahoma and Arizona.
An engineer reads your note and tells you the pathway, the agencies involved and what decides cost and schedule.

Projects
Sweetwater, TX
TxDOT’s IH-20 work meant moving four miles of the Bitter Creek Water Supply Corporation’s waterline. MES provided construction-phase engineering: site visits, submittal review, coordination and field reports. Customers kept water service throughout. Field work wrapped up in December 2024, and MES sent TxDOT the final pay application and as-builts in February 2025.

Colorado
Treatment upgrades with construction oversight (pumps, filters, SCADA and turbidity monitoring), plus a capital plan for 40,000 feet of line rehabilitation.

Sasakwa, OK
The condition and grant report, repair plans, bidding and construction support. The recoating and structural repairs are complete.

Not on its own. The provider has to have the capacity and hold the right to serve your land, and the fire flow has to work. We check all three before design. The utility’s own commitment is what binds it.
Yes. We review the records and meters, build a hydraulic model and study water loss, then rank the repairs so the owner can budget and apply for funding.
Often both. TCEQ reviews public water system plans under 30 TAC Chapter 290. The city, district or water supply corporation that will own the lines reviews them against its own standards.

Not a salesperson. Someone who can tell you whether the pathway is real.
Your options, the agencies involved and the questions that decide cost and schedule.
No commitment to have the first call.
