Regional Water Authority

Cornerstones MUD participates in a regional water authority (RWA) whose mission is to reduce the use of well/ground water and increase the use of surface water. Reducing dependence on well water leads to a reduction in ground subsidence as required by Texas state law. Districts are required to reduce ground water usage by 30% by December 2013, the current plan is for Cornerstones MUD to convert to surface water no later than 2025. The North Fort Bend Water Authority (NFBWA) was created in 2005 to allow well owners like Cornerstones MUD to band together to mutually accomplish this mission. The NFBWA borrowed $300 million to finance water pipeline construction that extended from the City of Houston to northern Ft. Bend county. This water pipeline currently provides surface water to approximately 30 MUD’s inside the NFBWA footprint. By over-conversion to surface water in those Districts, the remaining Districts in the NFBWA footprint can continue to use ground water until the next required reduction no later than 2024.

The RWA fee included on your monthly invoice provides for re-payment of the borrowed funds and ongoing operations of the Authority. The NFBWA increased that fee from $2.70 per 1,000 gallons used to $3.05 per 1,000 gallons used effective January 1, 2017. Cornerstones MUD’s rate order required that this fee be passed through to you the consumer at cost. This fee is expected in increase annually as NFBWA is planning to borrow more funds to build additional water infrastructure.

SI Environmental handles all billing and payments for Cornerstones MUD.

Summary of Water Conservation, Drought & Emergency Contingency Plan

The District’s Fourth Amended Drought Contingency Plan was adopted on November 19, 2012, for times of severe shortage of rainfall and decreased water supply, and to ensure that adequate supplies of water are maintained in the District.  During such times, the District will distribute information to its residents and other users of water regarding water conservation.

In general, drought conditions are reached when the water supply reaches 80% of the District’s production capacity for three consecutive days.  During such times, the following measures are taken:

  1. The District will inform water users of the drought conditions, and any restrictions on water use by notices and press releases.
  2. During mild drought conditions (75% capacity), the District will recommend that users voluntarily reduce water use.  Outdoor water use (lawn watering, car washing, etc.) will be limited as follows: even-numbered addresses may use water outdoors only on Wednesdays and Sundays and odd-numbered addresses may use water outdoors only on Tuesdays and Saturdays.  Outdoor water use shall be prohibited between the hours of 7:00 a.m. and 10:00 a.m., and between the hours of 6:00 p.m. and 10:00 p.m.
  3. During moderate drought conditions (85% capacity), in addition to the above requirements, outdoor water use may be conducted with a hand-held hose only.  The District will also recommend that non-essential water usage such as the filling of swimming pools and street washing be curtailed.
  4. During severe drought conditions (90% capacity), outdoor water use will be prohibited, a surcharge will be applied on water use in excess of 10,000 gallons per month, and in emergency situations the District may prohibit water use not essential to health and safety related uses, and impose penalties for violation of emergency response measures.  These penalties may include written notification for the first violation, and monetary penalties and discontinuation of service for subsequent violations.  Variances may also be granted for emergency conditions affecting health, sanitation and fire protection.
