B. DESIGN PHASE
1. Establish the scope, and advise the Owner, of any soil and foundation
investigations or any special surveys or special testing which, in the opinion
of the Engineer, may be required for the proper execution of the Project;
and arrange with the Owner for the conduct of such investigations and
tests. (The performance of these investigations and tests is not a part of
the Engineer's basic services, and compensation therefore is not included
in the Basic Charge; it may be performed by the Engineer, by agreement
with the Owner, in which case compensation shall be determined by the
applicable portions of Section VI A).
2. Fumish to the Owner, where required by the circumstances of the
assignment, the engineering data necessary for applications for routine
permits by local, state, and federal authorities (as distinguished from
detailed applications and supporting documents for govemment grants -in-
aid, state loan programs, planning advances or to meet the requirements of
the special programs of the federal govemment).
3. Perform field surveys to collect information which in the opinion of the
Engineer, is required in the design of the Project. Design surveying and
construction staking for the Construction Improvement is not included in the
Basic Charge.
4. Prepare detailed specifications and contract drawings, in pencil on paper,
for construction authorized by the Owner. These designs shall in all
respects combine the application of sound engineering principles with a
high degree of economy, and shall be submitted to the applicable state and
federal agencies for approval.

shall be included in the construction contract.
8. Provide a letter for the Owner's signature to each utility operating within the
City of Round Rock advising them of the project and describing any known
relocations to be performed by that utility and setting forth a proposed
construction schedule. This letter and a complete set of plans shall be
delivered to each utility by the Engineer. The Engineer shall provide timely
assistance and location stakes as necessary for utility relocations to assure
that utility relocations do not delay the project.
9. Provide easement and right -of -way descriptions to the Owner in conjunction
with submission of final plans. These will be provided in the form of field
notes and drawing of the affected properties. These services will be paid
for in accordance with Attachment No.3 - Hourly Rate Schedule.
10. Provide field note descriptions to the Owner for any site(s) that is required
for Owner to acquire that is associated with this Project. These descriptions

1. Assist the Owner in the advertisement of the Project for bids.
3
2. Assist the Owner in the opening and tabulating of bids for construction of
the Project, and recommend to the Owner as to the proper action on all
proposals received.
3. Assist in the preparation of formal Contract Documents for the contracts.
4. Make periodic visits to the site (as distinguished from the continuous
services of a resident Project Representative described in Subparagraph 6
below) to observe the progress and quality of the executed work and to
determine in general if the work is proceeding in accordance with the
Contract Documents. In performing this service, the Engineer will not be
required to make exhaustive or continuous on -site inspections to check the
quality or quantity of the work or material; he will not be responsible for the
techniques and sequences of construction or the safety precautions
incident thereto, and he will not be responsible or liable in any degree for
the contractors' failure to perform the construction work in accordance with
the Contract Documents. During visits to the construction site, and on the
basis of the Engineer's on -site observations as an experienced and
qualified design professional, he will keep the Owner informed of the extent
of the progress of the work, and advise the Owner of material and
substantial defects and deficiencies in the work of contractors which are
discovered by the Engineer or otherwise brought to the Engineer's attention
in the course of construction, and may, on behalf of the Owner, exercise
whatever rights the Owner may have to disapprove work and materials as
failing to conform to the Contract Documents.
5. Consult and advise with the Owner, issue all instructions to the contractor
requested by the Owner, and prepare routine change orders as required.
6. If specifically authorized by the Owner in writing, fumish the services of
resident Project Representatives, and other field personnel for continuous
on- the -site observation of construction and for the performance of required
construction layout surveys. (This service is not a part of the Engineer's
basic services, and compensation therefore is not included in the Basic
Charge; if provided, compensation shall be determined under Section VI A.)
The authority and duties of such Resident Project Representatives are
limited to examining the material fumished and observing the work done,
and to reporting their findings to the Engineer. The Engineer will use the
usual degree of care and prudent judgment in the selection of competent
Project Representatives, and the Engineer will use diligence to see that the
Project Representatives are on the job to perform their required duties. It is
agreed, however, that the Engineer does not underwrite, guarantee, or
insure the work done by the contractors, and since it is the contractors'
4
responsibility to perform the work in accordance with the Contract
Documents, the Engineer is not responsible or liable for the contractors'
failure to do so, and, so long as Engineer has exercised the usual degree of
care and prudent judgment in selecting Project Representatives and has
used diligence to see that they are on the job to perform the work, failure by
any Project Representatives or other personnel engaged in on- the -site
observation to discover defects or deficiencies in the work of the contractors
shall never relieve the contractors of liability therefore or subject the
Engineer to any liability for any such defect or deficiencies.
7. Review samples, catalog data, schedules, shop drawings, laboratory, shop
and mill tests of materials and equipment and other data which the
contractor is required to submit, only for conformance with the design
concept of the Project and compliance with the information given by the
Contract Documents; and assemble written guarantees which are required
by the Contract Documents.
8. Review monthly and final estimates for payments to contractors, and fumish
to the Owner any necessary certifications as to payments to contractors
and suppliers in a form acceptable to the City.
9. Conduct, in company with the Owner, a final inspection of the Project for
conformance with the design concept of the Project and compliance with
the Contract Documents, and approve in writing final payment to the
contractors.
10. Revise contract drawings, with the assistance of the resident Project
Representatives, or the Owners representative, to provide record drawings
of the completed Project. Fumish one set of reproducible drawings and one
set of prints of there revised drawings to the Owner.

RE: Irrigation of Forest Creek Golf Course with East Wastewater Treatment Plant Effluent
This letter presents information associated with use of effluent from the East Wastewater
Treatment Plant (East WWTP) to irrigate the Forest Creek Golf Course. Specific items that are
addressed in the letter are listed below:
• Background information regarding irrigation at the Forest Creek Golf Course.
• Texas Natural Resource Conservation Commission (TNRCC) requirements applicable to use
of effluent for golf course irrigation.
• Physical facilities required to allow conveyance of effluent to and use at the Forest Creek
Golf Course.
• Estimated costs of facilities required to allow use of effluent for golf course irrigation.
irrigation at the Forest Creek Golf (Curse
The Forest Creek Golf Course currently is irrigated from an irrigation pump station adjacent to
the fifteenth fairway. The pump station obtains water from a pond which is fed from a well at
the golf course, from surface drainage to the pond, and from the City of Round Rock water
distribution system. The drainage area to the pond appears to be on the order of four to five acres
based on a USGS map. Golf course personnel indicate that they are currently applying
approximately 300,000 gallons of water per day to the golf course, and that they would like to-
apply about 660,000 gallons per day during the summer, the desired summer application rate
appears to be reasonable.
Information regarding the irrigation system is listed below:
• Pond capacity is estimated to be about 500,000 to 600,000 gallons. The estimated capacity is
based on paced estimates of pond dimensions and visual estimates of available pond depth.
• City of Round Rock staff indicate that the pond was constructed with one foot of clay liner.
• Golf course personnel indicate -that the irrigation pump station has three pumps and has a
total capacity of 1,800 gallons per minute (gpm).

TNRCC Requirements
Effluent use for golf course irrigation is covered by Chapter 310, Use of Reclaimed Water of the
TNRCC rules. Chapter 310 is currently in the process of being updated and revised, and the
TNRCC is also in the process of evaluating their posture.on reuse. Based on the. current Chapter
310 requirements and discussion with TNRCC staff, TNRCC requirements that appear to apply
to your project are listed below:
1. Letter application to the Texas Natural Resource Conservation Commission ( TNRCC)
describing proposed use and requesting permission for use must be submitted.
2. An engineering report regarding the proposed use should be submitted along with the
application. The engineering report should address the requirements of Chapter 310, which
includes:
a) Effluent compliance with applicable quality parameters.
b) - Conveyance piping conforms to appropriate criteria for such use.
c) Storage ponds constructed such that they prevent groundwater contamination
(permeability of 1 x 10 cm/sec or less).
d) Water balance indicating that proposed application notes are consistent with consumptive
use of crops and leading requirements of soil.
e) Compliance with buffer zone criteria.
f) Compliance with other Chapter 310 requirements.
3. An operation and maintenance plan for the irrigation operation must be submitted along with
the application.
The East Wastewater Treatment Plant produces an effluent that complies with Chapter 310
requirements for irrigation restricted access areas. Golf courses are considered restricted access
areas as access is controlled by management practices.
Water balance and application rate issues should not be a problem as this is an irrigation project
in which effluent is used as needed by plants. Water balance calculations and application rates
are more important on land disposal projects that are aimed at wastewater disposal rather than
plant maintenance.
Lining of the existing golf course pond that supplies the golf course irrigation system must be
certified by an engineer as complying with TNRCC permeability reuirements. Field tests would
be required to verify permeability unless construction records adequately document the design
permeability of the pond liner. It is possible that field tests would require that additional liner be
placed in the pond in order to comply with TNRCC requirements.

City of Round Rock
August 7, 1996

ATTACHMENT 1
TNRCC requirements allow use of ponds that store treated effluent to receive runoff, but the
requirements indicate that any overflow must provide a ten to one dilution of treated effluent. In
the case of the pond at the golf course, it appears that diversion of runoff around the pond could
be accomplished relatively economically, and diversion of runoff around the pond would be the
recommended approach. The pond does receive runoff from a school across Forest Creek Drive
from the golf course, and it may be necessary to construct a stormwater settling or holding basin
to receive runoff from the school.
The TNRCC typically requires buffer zones around effluent storage ponds, though the wording
of the regulations does not specifically indicate that buffer zones are required for storage
facilities for advanced secondary effluent such as is produced at the East WWTP. Buffer area is
not available for the existing golf course pond, but given the quality of effluent required by the
.TNRCC wastewater discharge permit for the East WWTP, it is likely that the TNRCC will not
require a buffer zone. It is possible that the TNRCC will require that the pond be fenced. Buffer
zones are generally not required by the TNRCC around areas on golf courses that are irrigated by
secondary or better effluent.
In summary, there do not appear to be any major TNRCC related problems associated with use
_ of East WWTP effluent to irrigate the Forest Creek Golf Course.
Physical Facilities
The location of the East WWTP and the irrigation pump station that serves the Forest Creek Golf
Course are shown in Figure 1 along with facilities that would be required to convey and use
effluent at the golf course. Existing facilities together with required facilities that are described
in this letter are shown schematically on Figure 2. The existing facility that is pertinent to this •
project is an eight inch diameter force main that extends from the plant east to County Road 122
and then south along County Road 122 to about Red Bud Trail. The eight inch diameter force
main is parallel to and connected with (through valves) a twelve inch diameter force main. The
design intent of the parallel eight inch and twelve inch lines was that the eight inch would
initially be used to handle flows from the lift station to the East WWTP, but that the eight inch
would ultimately be used to convey East WWTP effluent from the plant to the Forest Creek Golf
Course and the twelve inch, which was not initially in service, would convey wastewater to the
plant; this project is thus consistent with the original design intent of the piping facilities.
Major improvements that will be needed to allow use of the East WWTP effluent at the Forest
Creek Golf Course are listed below:
1. Connection of the eight inch force main to the nonpotable water system at the plant. The
nonpotable water system pumps were sized in anticipation of about 600 gallons per minute
(GPM) being provided to the Forest Creek Golf Course, so adequate capacity is available.
Mr. Jim Nuse, P.E.
City of Round Rock
August 7, 1996
Page 4
ATTACHMENT 1
The connection to the nonpotable water should include a tee on the line from the nonpotable
water system that will allow nonpotable water to be conveyed to both the Forest Creek Golf
Course and to Old Settler's Park if use of effluent at Old Settler's Park is desired.
Additionally, a pressure control valve should be installed near the connection of the eight
inch effluent conveyance line to the nonpotable water system to ensure that flow to the golf
course will not result in lower than desired pressures in the nonpotable water system. The
proposed connection is shown schematically on Figure 3.
2. Extension of eight inch force main from its current end (start) point in County Road 122 to
the golf course irrigation system pumping station. Approximately one mile of pipeline will
need to be constructed. Approximately six- tenths of a mile would be in County Road 122
right -of -way (ROW) and about four - tenths of a mile would be in Forest Creek Drive ROW
from County Road 122 to just south of the existing pond on the golf course that supplies the
irrigation pump station. We have not coordinated with Williamson County, but the extension
would be similar to the existing line in County Road 122 ROW and approval problems are
not anticipated. A potable water line is installed in the existing easement from County Road
122 to the golf course pond location; adequate separation (nine feet) will need to be
maintained between the potable water line and the effluent force main, and it is possible that
the easement will have to be widened to•accommodate the force main.
3. Effluent storage at the irrigation pumping station. The existing golf course pond that supplies
the irrigation pump station has adequate capacity to serve as a storage pond for effluent from
the East WWTP. The liner needs to be evaluated to determine if it complies with TNRCC
requirements; if the liner does not comply with TNRCC requirements, the liner will have to
be iomproved.
4. Surface drainage should be routed around the pond. Based on a very preliminary estimate of
drainage area to the pond, it appears that swales around the pond and a green adjacent to the
pond could be used to route runoff around the pond. More detailed information would be
developed during design to establish the size of the swales.
5. Chlorination of irrigation system pump suction lines. TNRCC rules require that coliform
levels be below certain limits when used for golf course irrigation. Chlorination facilities
should be provided to ensure compliance.
Control valve on the discharge line to the storage facility. A control valve should be provided on
the pipe to the storage facility. The control valve logically would be automatically operated to
maintain a level in the storage facility and should have an operating speed that minimizes surges
in the effluent force main.
Runoff from the irrigation operations must not be allowed to enter streams. Typically, the
TNRCC allows irrigation management as a means of controlling runoff on golf course and does
not require tailwater control measures.

A preliminary evaluation of use of the existing golf course pond to store plant effluent was
performed to estimate the level variation in the pond that might occur on a daily basis.
Information used or developed in the evalaution is listed below:
• Inflow of effluent to the pond = 600 gpm (continuously unless pond is full or inflow is
reduced by operators),
• Irrigation rate = 1,800 gpm,
• Peak daily volume used for irrigation = 660,000 gallons,
• Irrigation period required = (660,000 /1,800 times 60) = about 6.1 hours,
• Storage volume used during irrigation = (1,800 - 600)(6.1)(60) = about 440,000 gallons,
• Pond provides about 200,000 gallons per foot of depth, so pond level would decrease about 2
feet 2 inches during irrigation.
• It would take about 12 hours for the 440,000 gallons used from storage to be replaced at 600
gpm following the completion of irrigation.
The facilities described in this section are intended to provide effluent only to the Forest Creek
Golf Course. Based on the peak day amount of water desired by the golf course, the conveyance
facilities would not have spare capacity to convey effluent to other users during peak periods. If
there is a possiblity of or desire to serve additional users of effluent in the future, consideration
might be given to increasing the size of the line from the existing eight inch force main to the
golf course.
Estimated costs of facilities associated with the use of effluent at the Forest Creek Golf Course
are listed below. The estimated costs do not include the cost of any improvements that might
need to be made to the existing pond at the golf course.
