Prioritization of Drinking Water and Wastewater Projects
Project Application – Region 6
Sample Project – Border CityBrief Community Profile
Location: 12 miles north of US/Mexico BorderCurrent City Population: 50,000Utility Services: Centralized Water and Wastewater SystemsService Area: Border City (12,000 homes; 50,000 people) and
unincorporated area (1,200 homes; 5,000 people)
Condition of Existing Drinking Water and Wastewater Infrastructure
Drinking Water System: Wells and core distribution system constructed in 1920
Current connections – 12,000 homesCity wells – Elevated nitrate levels exist in 2
wells.Wastewater System: WWTP and core collection system
constructed in 1952 Current connections – 12,000 homesCollapsed lines and the WWTP operates at
98% of capacityWWTP design capacity: 6 MGD; current
flows: 5.9 MGD
Conditions of Unincorporated Community (East of Border City)Drinking Water Source: 80 % of the homes receive water only by water
hauling services.WW Treatment Source: Inadequate on-site systems – 100% latrines and
cesspools.
Sample Project – Border CityPOTENTIAL PROJECTS
DRINKING WATER1. Replacement of two primary wells due to nitrate levels
above MCL
2. Expansion of the water system to unserved residential areas
WASTEWATER3. Expansion of the wastewater collection system to unserved
areas AND expansion of the wastewater treatment plant to accommodate additional capacity, including limited rehabilitation/replacement of the core collection system necessary to support expanded service (i.e. Main Collector)
4. Replacement of collapsed wastewater lines throughout Border City.
A SEPARATE APPLICATION IS REQUIRED FOR EACH PROJECT
WWTP
Application 1. Expansion of the wastewater collection system andexpansion of the WWTP, include main collector.
Application 4. Replacement of collapsed wastewater lines.
Application 3. Expansion of the water system inter-related with Application 2 (new wells).
Application 2. New wells toreplace contaminated wells.
