1. Approved means of wastewater collection and treatment required. All lots, tracts or parcels on which development is proposed shall be served by an approved means of wastewater collection and treatment.
2. Possible phasing of development required.

(i) The City Engineer may require the phasing of development or improvements in order to maintain adequate wastewater capacity.
(ii) Subdivisions either in the ETJ or that have recently been annexed and are not served must meet the same requirements subject to approval by the City Engineer in coordination with the PUA or WCID-17 (See § 1.4.1: Letters of certification).

(i) Any development occurring within five hundred (500) feet of an existing or proposed wastewater line shall extend and connect to the existing facilities.

(i) A proposed Subdivision must provide an approved wastewater disposal system conforming to the current criteria, plans, regulations and requirements of Travis County, Texas Administrative Code Title 30, Part 1, Chapter 285 On-Site Sewage Facilities and Texas Commission on Environmental Quality On-Site Sewage Facilities licensing requirements.
(ii) The City will make the final determination of the adequacy of the proposed system.
(iii) Lots on the Edwards Aquifer Contributing Zone as depicted on the official map of the TCEQ that will not be connected to the public wastewater system must have an area of at least one-half (0.5) acre. When it is difficult to determine from the maps of the TCEQ whether particular lots lie within the Contributing Zone, the City may make the determination, based upon a geological inspection of the site by a professional geologist competent to perform this task. The geologist must be approved by the City Engineer prior to conducting the inspection and the inspections shall be conducted at no cost to the City. Any rules or regulations required by Travis County must be met in addition to this section.

(i) All laterals and sewer mains installed within a Subdivision must extend to the borders of the Subdivision as required for future extensions of the collection system, regardless of whether such extensions are required for service within the Subdivision.
(ii) If due to physical constraints, a new Subdivision will never be constructed beyond a proposed Subdivision, the City Council may approve a Subdivision Waiver (see Section 2.6: Subdivision Relief Procedures) for this requirement prior to action on a Plat or Subdivision Construction Plans.
