General Aspects
Project Location
 The City of San Juan is located in Hidalgo County, approximately 5 miles
east of the the City of McAllen. The City is approximately 5 miles north
of the U.S./ Mexico Border.

Originally constructed in the 1960s, Water Treatment Plant I (WTP-I) has a treatment capacity
of 1.5 MGD, but with a much needed upgrade. Currently operating when Water Treatment Plant
II goes off-line for maintenance. An onsite clear-well has a storage capacity of 1.0 MGD.
Water Treatment Plant II (WTP-II) is the largest and primary water treatment plant with a
treatment capacity of 3.5 MGD and a clear-well storage capacity of 439,000 gallons.
Raw water is obtained from the Hidalgo County Irrigation District No. 2. Total storage of treated
water is approximately 2.0 MGD which meets TCEQ requirements.
On-site visit to WTP-II showed four filters, which are backwashed daily, consuming
approximately 200,000 gallons of treated water per day. Asbestos Concrete & Steel water lines
are still present in the distribution system. Testing of these lines showed no contamination, but
these line materials have been banned for use by the TCEQ.
Undersize pipes and recent waterline breaks show that some water lines are located within
private properties.
Existing water rights are typically supplemented with spot purchases from Hidalgo County
Irrigation District #2.
Concern: Capacity impacts due to WTP-II filters backwash requirements.
Capacity impacts of summer. Asbestos Concrete (AC) & Steel lines. Inaccurate
system inventory.

General Aspects
Proposed Water Systems Improvements
• WTP-I upgrade or replacement to meet system demands.
• WTP-II upgrade and expansion through the addition of claricones, filters, clear-wells
and other necessary equipment to overcome shortages.
• The water distribution system will be upgraded by replacing over 115,600 linear feet of
AC and steel water lines throughout the City. Waterlines will be relocated out of private
property and within easements which will need to be purchased.
• Fire hydrants and additional necessary equipment will be replaced and/or added to the
existing distribution system to meet demand and safety requirements, as well as the
replacement of undersized lines.
•Secure adequate water rights.
Total Estimated Cost – $11,700,897 (Based on DWSRF IUP
Application); 2003 DWSRF has approved $1,125,000 for the
water storage component of the project.

General Aspects
State of Existing Wastewater Collection & Treatment
 Recent upgrade construction work at the wastewater treatment plant
(WWTP) rated the plant at 4.0 MGD, from which 30% is currently used.
 The City provides wastewater collection inside and outside the city limits.
 Approximately, 65% of the service area has sewer service coverage. The City
also supplies sewer service to areas where North Alamo WSC provides water
service.The remaining 35% does not have sewer service at the present time.
 Areas of concern with the existing collection system includes clay collection
lines and brick-lined manholes which cover most of the Original Townsite of
the City, creating infiltration and leak problems in the area.
 Concern: Environmental and human health risks due to existing clay
collection lines and brick-lined manholes in the Original Townsite of the
City, leading to infiltration and leak problems. Existing not served areas.

General Aspects
Proposed Wastewater Systems Improvements
• Wastewater Collection System Upgrade and Expansion throughout the
Original Townsite of the City:
 Replacement of approximately 86,700 linear feet of clay sewer lines.
 Replacement of approximately 300 brick-lined manholes.
• Extend wastewater service to 3 Colonias covered in the 2003 CWSRF.
Total Estimated Cost – $5,869,296 (Based on City
Engineer’s Estimates); 2003 CWSRF has been approved in
the amount of $1,300,000 to support wastewater service to 3
Colonias.

Environmental and Human Health Indicators
Compliance with Environmental Norms & Regulations
 The City is concerned that the lack of adequate storage water capacity
would lead to violations of the requirements of the water treatment permit and
of the Texas Administrative Code (290.44D).
 The City of San Juan received a Certificate For Outstanding Performance
from TCEQ for having no violations related to the “Total Coliform Rule” in
their public water system from 1997 to 2001.

Environmental, Human Health and
Sustainable Development Strategies
•Environmental and Human Health:
 Document potential environmental impacts caused by outdated infrastructure
technology, such as clay sewer pipes, brick-lined manholes, AC and steel lines.
 Describe the risk of inadequate clear-well storage capacity, which may lead to low
pressures in distribution system or insufficient water supply.
 Referenced the enforceable standard requiring fire flow protection.
 Eliminate the risk associated with current water system needs for fire protection,
pressure, delivery, storage and treatment.
 Invite Texas Historical Commission to participate in project planning.

Environmental, Human Health and
Sustainable Development Strategies
•Sustainable Development:
 Conducting Sustainable Development Workshops; Baseline Conditions report complete.
 Water Conservation and Drought Contingency Plan needs to be updated.
 Operator review at 30% design.
 Rate Study – Determine affordability with sufficient funds to support O&M and
reserves. Request submitted to the NADB.
