What should a civil engineering firm verify before handing a wastewater lift station design to a specialist?

Which TCEQ rules and submittal path apply?

30 TAC Chapter 217 sets the design criteria, and the default submittal is a summary transmittal letter. TCEQ's wastewater design rules page says the standards are established in Title 30, Texas Administrative Code, Chapter 217, adopted in 2008 and revised in 2015.

Under TCEQ's wastewater design requirements, you send a summary transmittal letter to TCEQ, with a copy to the regional office, for each collection system and wastewater treatment facility project. Two cases change that:

• No letter is needed if the Texas Water Development Board or an approved municipality has granted approval.
• A collection system project over the Edwards Aquifer recharge zone needs no letter, but submits full plans and specifications to the regional office in Austin or San Antonio.

Confirm with the reviewing parties which path your project follows before anyone assumes a letter is or is not needed. If the site could be near the recharge zone, settle it at the handoff, not at submittal.

Who prepares and seals each part of the package?

Name the engineer of record for the lift station sheets before design starts. TCEQ's requirements say the letter includes a Texas registered professional engineer's statement that the plans and specifications meet all design criteria requirements.

The letter also carries the design firm's name, address and Texas Board of Professional Engineers firm registration number, and the design engineer's signature and seal.

Those items lead to contract questions. These are suggestions, not TCEQ requirements:

• Who is the engineer of record for the lift station and force main sheets?
• Which firm's registration number goes on the letter?
• Who reseals the sheets if your site plan moves after the design is done?

Our page on support for engineering firms explains the two ways MES works for another engineering firm, and who seals what in each.

What does the letter need from your site plan?

A station name, an exact location, the emergency power plan and any variances. For a lift station, the letter's project scope gives the station's name and its longitude and latitude in decimal degrees with six decimals. Put a working name and a confirmed location in the handoff package.

The project scope also describes the provisions for emergency power to the collection system. Tell the specialist what power service or utility coordination you already know, and mark what is still open.

Variances need an owner. The letter carries a justification for each variance and a statement certifying that any variances will not threaten public health or the environment. If your site plan forces a departure from a design criterion, flag it so the specialist can address it deliberately.

How do the lift station, force main and power fit together?

Through Chapter 217 rules that reach back into your site plan. The lift station and force main sections set requirements that depend on decisions you make about the site.

Under 30 TAC §217.63, a lift station must:

• raise alarms for power outages, pump failures and high water levels, sent to a continuously monitored location;
• prevent a discharge during a power failure, for the longest outage in the past 60 months of the electric utility's records or 20 minutes, whichever is longer;
• stay fully accessible during a 25-year, 24-hour rainfall event.

Those outage records come from the electric utility, on its letterhead and signed by a utility employee, so agree early on who requests them. Access during that storm depends in part on your grading and drive layout.

Under 30 TAC §217.67, a force main design must include effective surge control for water hammer, and the force main must end at a collection system manhole, or at a manhole or preliminary treatment unit at a treatment facility. The receiving collection system must be designed to accept the maximum pump discharge without surcharging.

So the route, the receiving manhole and its downstream capacity belong in the handoff. Our walkthrough of force main and pump sizing calculations shows how those inputs drive the design.

What review could follow the letter?

The letter may be the end of it, but TCEQ can ask for a full technical review. TCEQ lists alternative collection systems, treatment facilities with an unsatisfactory compliance history, and innovative or nonconforming treatment technologies as typical full-review projects.

A conventional lift station may not fall in those groups, so do not assume a full review will or will not happen.

If TCEQ decides a full technical review is needed, the design engineer receives notice within 30 working days of TCEQ's receipt of the summary. You then have 30 days to submit:

• a complete set of plans and specifications;
• a complete engineering report;
• justification for all requested variances;
• enough information to show the project complies with the rules.

Ask the specialist whether they can support that window and who on your team coordinates it. No handoff can promise a review outcome or a date.

Is your handoff package ready?

Only if you can answer yes to all six items below. Any no means hold the handoff, close the gap, then send the package.

1. The written scope says what the specialist designs (lift station, force main, power, controls) and what stays with you (grading, access, easements).
2. The engineer of record and the sealing firm are named, with a plan for resealing after changes.
3. You have confirmed whether the TCEQ letter, a Texas Water Development Board or approved municipality approval, or the Edwards Aquifer path applies.
4. The station's name and location are set.
5. Known variances and emergency power constraints are listed, with a named person requesting the utility's outage records.
6. The force main route and receiving manhole are shown, or marked as undecided.

Bring these questions to the handoff meeting:

• What do you need from us that is not in this package?
• Which assumptions in our site plan would you change?
• Who answers agency comments, and how fast?
• What would make you decline part of this scope?

Send the specialist your draft scope and open-items list before the meeting, so the conversation starts from the gaps.

This guide is general education from TCEQ's public pages and 30 TAC Chapter 217 as of October 2026. It does not size a station, and the responsible engineer's judgment governs your project.

Frequently asked questions

Should the handoff wait until the site plan is final?

Not necessarily, but the station location, force main route and receiving manhole should be firm enough that the specialist is not redesigning around moving targets. Mark anything still open as an open item, not a fixed input.

Does every lift station need a TCEQ summary transmittal letter?

No. TCEQ says no letter is needed when the Texas Water Development Board or an approved municipality has granted approval. A collection system project over the Edwards Aquifer recharge zone sends full plans and specifications to the regional office instead.

I run a small civil firm in Texas and I'm handing a lift station design to a wastewater specialist. What should the scope say so nothing falls between our site plan and their design?

Name each interface and its owner: the station pad and all-weather access, the force main route to the receiving manhole, the power service and backup, the alarms and their monitored location, and who answers TCEQ comments. Put that list in the contract.

We are a civil engineering firm with a Texas site that may sit over the Edwards Aquifer recharge zone. Does that change how the lift station gets reviewed?

It can. TCEQ says collection system projects over the recharge zone do not need a submittal letter but must submit full plans and specifications to the Austin or San Antonio regional office. Confirm where the site sits before the handoff.

Does this checklist guarantee a smooth review?

No. It reduces avoidable gaps. Agency review outcomes and timing depend on the project and the agency.
