Riverchase Point of Entry
Dear Mr. Ginn:
In response to the point of entry request dated April 21, 1987, the Authority
has reviewed the construction standards to be utilized on the point of entry at
station 130+98. The Authority approves your request based upon the information
submitted which includes the construction plans for Riverchase Development by
Nathan D. Maier dated November 1985, but is subject to the following
requirements.
1. Central Regional Wastewater System Engineering Division must be
contacted (214 263-2251 or 214 262-5186) at least 72 hours prior to
construction. If the Authority is not notified the Authority
reserves the right to request the contractor to excavate his work.
All inspections will be performed only by Authority inspectors.
City inspectors are not responsible for Trinity River Authority
property.
2. All points of entry must be constructed within one year after their
acceptance by the Authority. Any alterations to the plans
concerning the Authority's interceptors, meter stations, point of
entries or easements must also be approved by the Authority.
3. A preconstruction meeting with the contractor and the Authority
is required prior to construction.

4. All P.V.C. connections shall use A.C. pipe adaptors.
* 5. Connections to the interceptor shall be by sawcut or core drill
method only. Jack hammering will not be allowed.
6. The Authority's interceptor is encased from Station 129+00 to
Station 131+00. A standard manhole does not apply here therefore a
shop drawing of the proposed manhole must be submitted prior to
construction of the manhole.
7. The Authority recommends all incoming point of entry flow lines
should be at least above the spring line of the Authority's
interceptor, preferably above the crown. The Authority is not
responsible for overflow resulting from connections below the
recommended distance from the flow line of the Authority's
interceptor.
This point of entry shall serve the City of Coppell and will be metered at
Meter station 17.0E.
In addition to this, personnel from the Engineering Division must be onsite
during construction, as well as prior to any backfilling of the Authority's
facility in this area.
If you have any questions or comments please contact me.
