Subjeci: M-189 Sew�r Mainlmpravements
Dear Mr. Harder:

As part of the ongoing Sewer System rinpxovement Project in the M�189 Drainage Area, RTN has
identified several areas that can be addxe�sed to alleviate several of the chronic manhole
overflows a.�d backups in ihe study area. These areas are as fol�ows:
1. Chronic ov�rflow at 5500 Westcreek — RJN has reviewed the CCTV insp�ction �ogs o£the
L-6655 and M-240 sewer downstream of this o�rerflow. The L-6655 sewer waS found to be a
6-inch cEiameter sewer with a CIPP liner, not an 8-inch diameter PVC sewex as shown on the
existing map. The L-6655 sewer contaa�us zx�ulfiiple sags and in one area has a severe offset
joint that has shearad the CIPP liner.
RJN also smoke tested the L-5751 and L-5624 sernrers upstream of the overflow. No major
sources af inflow were identified. The CCTV tapes show these sewers to have several
sectians of broken and cracked pipe that can be addressed through pipe burstinga
To eliuminate the manhole overflow at 5500 Westcreek, it i� reeommend�d that the L-6655
sew�r b� replaced with an 8-inch diameter sewer from sta. 13+6$E to sta. 51+73 on M-240.
Also, the M-240 sewer would be replaced from sta. SI+'73 to sta. 48+78. It is recommended
�hat tiie L-5731 sewer be�ween sta. 6+09 and the L-6655 se�ver be relocated to Winfred
Drive. The LWGGSS sewer vvould be extended to #he intersection of Wosley Drive and Wilkie
Way. The existing L-5731 �ewer downstreanl of sta. 6+09 would be abandoned and the
services re-routed to the proposed sewers in Wosley and Winfred Drive.
2. The M-256 sewer main between sta. 27+52 and sta. 22+95 was found to be in a sever� state
of deterioratio�. This segment has missing pip� with large voids and passes direcily under a
dentist office. It is recamnr�ended that the sewer be re-routed to the north and into th�;
existing L-5545 sewer.

3. The r�view of �th� CCTV inspectxan data by Field Operations has determined that se�eral
sewer sections downstream of known overflows have not been pxeviously televised. In order
to prepare a comprehensive overflow eliminatian plar� it is recommended that these sewers be
included in the current M-i89 cleaning prograrn. This would increase the total cleaning and
CCTV iraspect�on fram 103,000 linear feet to I50,000 linear feet.
Ac�ditional Ite�ns
The Water Department staff has also requested that RJN Group, Inc. provide GTS mapping for
the wastewater collection system in the study area. The mapping will be in accordance with the
pilot project cornpleted by RJN and appxoved by the Gity's GIS Departm�nt. The Data Pick List
is limited to the following items:
Nodes

GPS - Y, N

During ihe field investiga�ian of the M-189 Dra.ina�e Are we identified 130 potential main line

includes 30 dye t�sts. An additional 104 will be required tQ complete this task.

As requesfed by the Water Dapartment staff, RJN has prepared a proposed amendment to include
ihe abave task �to the e�isting contracto The proposed Amendm�nt also includes the design af
the M-176 an.d LC-8279 reloeations. A summary o£ fhe proposed amendment is included in the
attached Table 1. The estimatec� eonstruction cost of th� sewer replacementslrelacations fs also
enclosed.
We are alsa inciuding an estimaied cost to review a1135 CCTV tapes provided by Field
Operations from the M-189 Drainage Area.
RJN Group, Inc. int�nds to utilize Spelunker Pipeline for the cleaning and CCTV inspectxon
poz�tion of the amendment. Their partici�ation is an��cipated to be approximately $b8,000 or
30 percent of the tota[ amendment aanount.
We appreciate t�e opp�rtun�ty fio provide these additional services to the Fort Worth Wate�r
