Before starting construction, where must utility companies submit their engineering plans?

Utility companies are required to submit their engineering plans to the Texas Commission on Environmental Quality (TCEQ) before starting construction to ensure compliance with state regulations and environmental standards. The TCEQ oversees the implementation of water quality standards and enforces the regulations related to the construction and operation of water systems in Texas. By requiring the submission of these plans, the TCEQ can evaluate the designs for safety, environmental impact, and adherence to public health guidelines.

Submitting plans to the city planning office may be necessary for local permits but does not encompass the broader environmental considerations required by the state. The American Water Works Association (AWWA) provides guidelines and standards that may inform project design, but it does not have the regulatory authority to approve engineering plans. Similarly, while the Environmental Protection Agency (EPA) sets federal standards for water quality, the actual enforcement and approval process at the state level is managed by the TCEQ. Therefore, the submission of engineering plans to the TCEQ is essential for ensuring that water systems are constructed following legal and environmental standards.
