General Aspects

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.

Project Location

City of San JuanRapid Assessment Process Project Strategic Plan

State of Existing Water Treatment, Storage, & Distribution System

General Aspects

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.

City of San JuanRapid Assessment Process Project Strategic Plan

• 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.

Proposed Water Systems ImprovementsGeneral Aspects

City of San JuanRapid Assessment Process Project Strategic Plan

Existing Water System

City of San JuanRapid Assessment Process Project Strategic Plan

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.

State of Existing Wastewater Collection & Treatment

General Aspects

City of San JuanRapid Assessment Process Project Strategic Plan

• 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.

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 and Human Health IndicatorsCompliance with Environmental Norms & Regulations

City of San JuanRapid Assessment Process Project Strategic Plan

•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.
