Dear Corporation Member:

Dear Corporation Member:

On September 16, 2019, the East Rio Hondo Water Supply Corporation (ERHWSC) Board of Directors approved the following water and wastewater rate structures. The new rates, fees, and a change to the water gallonage rate, as outlined below, will take effect after October 30, 2019 and will apply to all billings mailed on or after November 30, 2019. Please note that this is a conservation rate structure. Members that use larger amounts of water will pay more per thousand gallons as they use more of the system’s capacity.

Effective 04/30/2018
Effective 10/30/2019
5/8"X3/4" 1.0 $40.00 $42.00 1,500
1.0" 2.5 $100.00 $105.00 3,750
1.5" 5.0 $200.00 $210.00 7,500
2" TURBINE 8.0  $320.00 $336.00   12,000 
 3" TURBINE 17.5 $700.00 $735.00 24,000 
4" COMPOUND 25.0 $1,000.00 $1,050.00 37,500
4" TURBINE 50.0 $2,000 $2,100 75,000

In addition to the minimum monthly rate noted in the table above, a gallonage charge shall be added at the following rates for usage above the base usage during any one (1) billing period. The current and new gallonage rates per 1,000 gallons in each tier are noted below:

Current New
1) $3.00 $3.50 per 1,000 gallons for any gallonage between 1 and 8,000 gallons above base usage;
2) $3.50 $4.00 per 1,000 gallons for any gallonage between 8,001 and 18,000 gallons above base usage;
3) $3.75 $4.25 per 1,000 gallons for any gallonage between 18,001 and 48,000 gallons above base usage;
4) $4.25 $4.75 per 1,000 gallons for any gallonage 48,001 gallons or more above base usage.

The average consumption of water for ERHWSC members is approximately 6,700 gallons per month. Based on this gallonage, the bill prior to this change in rate would have been $55.60 and with the new rates, the bill will be $60.20, which equals to a change of 8.27%.

Wastewater Service: The current monthly wastewater rate (minimum) is $37.00 with a base usage of 2,000 gallons. The new rate is $39.00 and will include a base usage of 1,500 gallons in order to mirror the base usage of water. The gallonage charge remains unchanged at $3.00 per thousand gallons for usage above 1,500, with a gallonage cap on residential customers at $30.00.

The following changes to the Corporation fee schedule are as follows:

Fee Description                                              Current Fee                                New Fee
Meter Installation Standard Service with Tap        $225.00                                   $420.00
Meter Install Standard Service without Tap           $425.00                                   $912.50
Late Payment Fee (whichever is larger)               $5.00 or 7.5%                          $7.50 or 7.5%
Reconnect Fee                                                 $35.00                                     $40.00
After Hours Reconnect Fee                                $60.00                                     $65.00
Service Trip Fee                                                $35.00                                     $40.00

Fire Suppression Service Fee                             $25.00                                     $35.00
Backflow Tester Application Fee (New)                                                               $100/year
Backflow Test Fee (New)                                                                                   $25/device/year

After serious consideration, the Board of Directors implemented these rate and fee changes for the following key reasons:

1. Additional capital is required to meet financial requirements of continued increases in operational expenses, debt service, and capital expenditures. [Capital expenses include water line upgrades, vehicle purchases, backhoes, trailers, water rights, plant upgrades, manhole repairs, and TXDOT adjustments. Debt service is specifically related to wastewater system expansion, Texas Commission on Environmental Quality (TCEQ) compliance, and access to alternative drought and emergency water supplies.]
2. The gallonage rates have not been increased since 2009.
3. Annual budgets are increasingly influenced by principal, interest, depreciation, and debt reserve requirements associated with loans for critical water and wastewater treatment plant and pipeline projects.
4. The Board of Directors has approved the consistent purchases of additional Rio Grande River water rights as they become available through development for ERHWSC’s future water supply.
5. ERHWSC works vigorously to maintain compliance with TCEQ rules to avoid wasting ERHWSC funds on noncompliance fines.
6. Inflation continues to increase the cost of all products and services.
7. Protecting ERHWSC’s members’ health is our main priority and associated good water quality and pressure are critical to better service for our members.
8. ERHWSC’s primary funding agency, United States Department of Agriculture Rural Development (USDA-RD), now requires ERHWSC to set aside funds for the duration of the loan for four of our construction projects. These set-aside significant funds are to be used only for maintenance of the new construction.

ERHWSC values your membership and wants you to be aware that you and your fellow members’ participation make our rural water system possible. Many of our members still remember the days of reliance on canal water for domestic uses. We have come a long way.
