  1. Prioritization of Drinking Water and Wastewater Projects Project Application – Region 6

  2. Sample Project – Border City Brief Community Profile Location: 12 miles north of US/Mexico Border Current City Population: 50,000 Utility Services: Centralized Water and Wastewater Systems Service 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 homes City wells – Elevated nitrate levels exist in 2 wells. Wastewater System: WWTP and core collection system constructed in 1952 Current connections – 12,000 homes Collapsed lines and the WWTP operates at 98% of capacity WWTP 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.

  3. Sample Project – Border City POTENTIAL PROJECTS DRINKING WATER • Replacement of two primary wells due to nitrate levels above MCL 2. Expansion of the water system to unserved residential areas WASTEWATER • 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) • Replacement of collapsed wastewater lines throughout Border City. A SEPARATE APPLICATION IS REQUIRED FOR EACH PROJECT

  4. SAMPLE PROJECT: BORDER CITY Application 4. Replacement of collapsed wastewater lines. Application 2. New wells to replace contaminated wells. Application 3. Expansion of the water system inter-related with Application 2 (new wells). WWTP Application 1. Expansion of the wastewater collection system and expansion of the WWTP, include main collector.
