Ice Storm and PFUD Operations

The recent ice storm tested the resiliency of the Prestonwood water and wastewater facilities.

Prestonwood fared better than many utility districts because we did not lose our electrical service since we are in the same electrical supply grid as the local hospitals.

In the event of a power interruption, our water supply and wastewater treatment systems are both equipped with standby generators to ensure continuous service.

Prestonwood’s water supply is provided by both in-district water wells #1 and #2, and treated surface water provided by the North Harris Regional Water Authority (NHRWA) delivered by pipeline to Water Plant #2 (Camborne Lane).

Unlike the City of Houston supplied water (NHCRWA) that required a “boil water notice,” Prestonwood UD did not issue a boil water notice because our system operator switched our water supply to 100% in-district water wells until the COH boil water notice was discontinued.

Prestonwood residents can be assured that PFUD Board is dedicated to provide the most reliable services to our neighbors that we can.

To maintain and approve our system reliability:

  • Standby water wells Nos. 1 and 2 are regularly tested and maintained in a ready condition.
  • Capital budget projects include replacement of  aging standby generators for Water Plant # 2 and the Wastewater Treatment Plant.
  • Other scheduled projects are designed to reduce the impact of flooding caused by storms like Harvey.

PFUD is also fortunate to have the support of consultants that have over thirty years of continuous service with the District.

Water District Management (WDM), the operating company that operates and maintains our facilities, deserves a well earned praise for the proper and timely winterizing prior to the freeze. Many utilities failed to winterize and the result was unnecessary outages and hardship for the customers.

Update From Your Water Board

We have completed the demolition projects that were mentioned in the “GOOD NEWS FROM YOUR WATER BOARD” article published in the Prestonwood Press in the June issue.  We continue to improve our system and facilities.

  1. All of the trees and shrubs at our 3 facilities have been pruned so as to improve the grass area around them and allow us to add some bedding plants at the treatment plant on Cypresswood Dr.
  2. All of the trees along the community side of Cypresswood Dr. have also been pruned to allow sunlight to the grass area under them and also improve the line of sight for drivers exiting our community.
  3. We are also looking for ways to improve the landscaping in front of the Cypresswood plant and along the fence that runs parallel to the new Vintage Park bridge.
  4. There are plans to upgrade both Water Plant 1 at the end of the 8200 block of Camborne and the treatment plant on Cypresswood. The good news is that we have been budgeting for this for some time and will NOT have to issue any bonds or raise our rates to do so.
  5. We have also had multiple streetlights installed on the north side of Cypresswood across from the Prestonwood Forest intersection.

We know all of you are concerned about the rising cost of water and so are we.  We have also heard from many of you and seen confusing articles on the “Next Door” website.  I mentioned that North Harris County Regional Water Authority (NHCRWA) delayed their 2020 rate increase from April 1 until July 1 this year.  Unfortunately you have probably already seen that it has been assessed.  Water is becoming more and more a precious commodity.  Some areas of Texas and the rest of the country have seen their sources dry up.  Some parts of Harris County have seen as much as a 10’ drop in subsidence due to the lowering of area water tables.  The good news is that Harris County saw this as a future problem and developed Lake Conroe, Lake Houston, and Lake Livingston to assure us of a long term source of drinking water back in the 1950’s.  The NHCRWA was developed in 1999 to start delivering water to the growing northwest part of Harris County.  With the increasing development of this NW area that is an ongoing process.  There are two other water authorities, one on the west side and the other in Ft. Bend.  The laying of underground piping, acquisition of land, and a treatment plant are all paid for with bonds and the ever increasing cost of the water that is delivered.  Prestonwood Forest is fortunate that we still have two good wells and do not have to use 100% surface water year round.  The mandate that accompanied this plan was that the NW area would be accepting the delivery of 30% surface water by 2010 which was accomplished.  The next goal is to be taking 60% by 2025 and then 80% by 2035 so you can see that this is not the end of water cost increases.

Your new water rates effective July 1 are as follow:

  • Groundwater – $4.50 / 1000 gallons (PFUD)
  • Surface water – $4.70 / 1000 gallons (NHCRWA)

If you would like to know more about the NHCRWA please go to their web site at or the website.

We ask that you continue to conserve water.  For suggestions as to how you can do this please consult the PFUD web site and read the inserts that we provide on a regular basis in your water bill envelopes.

Good News From Your Water Board

We are happy to say that your water board has been busy trying to maintain our facilities to their optimum level.

First let me pass on the information from North Harris County Regional Water Authority. They were going to raise the rate they charge us for surface water on April 1, and we then direct pass on to you. They have agreed due to the virus to delay the start of the increase to July 1 of this year.

Many of you have seen trucks in the community over the last few months. They have been slip lining our waste lines to improve water flow and prolong the life of our system.

You may know that we have two water wells in the community, one off Schroeder road near the Prestonwood town homes and the other at the end of the 8200 block of Camborne. A few years ago we built a new concrete 500,000 gallon tank and a wall around it at the Camborne location, but left the galvanized tank in place. It has been out of service for a while since it has reached its useful service life. Because of this and the fact that it was built when we opened the subdivision, we have decided to take it down which happened the first week of May. (See attached pictures)

The other major project being done the same week is taking down the elevated belt press at our water treatment plant on Cypresswood at the Prestonwood Forest intersection. For those of us that live closest to Cypresswood it has been an eyesore for a long time. When it was built Cypresswood did not exist so it was a non-issue. It was used to process sludge from the water treatment process, but the board based on a financial analysis has decided to remove sludge by an alternate method. To remove the building it was planned to just lift off the canopy housing and then the press itself. Best plans sometimes have an OOP’S. The computer on the crane miscalculated and locked up causing the crane to be lifted up. (See attached pictures) The contractor then had to bring in two MUCH BIGGER cranes to save the original one and then lift off the press. There were no damages or injuries. Concrete columns will come down the second week of May.

The good news for all of us is that the board has been planning on all this work for a long time and we have the funds to do it without raising rates, taxes, or issue bonds!

The Rising Costs of Water – Rates Increase

The current rate charged Prestonwood water users by the North Harris County Regional Water Authority (NHCRWA) is $4.10 per thousand gallons usage, this is a $.25 per 1,000-gallon increase over last year. NHCRWA has indicated they plan to implement annual increases in $.50 increments beginning July 1st. This cost is billed to Prestonwood Forest Utility District (PFUD) and will be passed on to the user unchanged. It shows up on your bill as a line item, “NHCRWA”.

Coincidental to these actions, PFUD is facing increased costs for the maintenance of the water and sewer infrastructure. Hurricane Harvey losses were partially recovered through our insurance. However, the need to implement mitigation measures to attempt to reduce any future flood damages from “Harvey”-like or even lesser storm events, plus the strain of maintaining a nearly 50-year-old infrastructure has caused the Board to rethink the water rates currently in place.

The Board has developed a 5-year plan to accomplish repairs, replacements and “Harvey” mitigation improvements with the intent of pay as you go, with no additional tax burden on Prestonwood users. This plan will require adjustments to the water and sewer rates for users.

Prestonwood will still maintain one of the lowest water and sewer rates in the region if not in the United States. The rates reflect the effort to promote conservation as required by State Law. Costs for usage above 5,000 gallons per month will increase incrementally as usage increases. Also, the board reluctantly determined that the “rebate”, which has been given for the last seven years, should also be eliminated to assist in funding improvements to our utility systems. The complete Rate Order is available on the Prestonwood Forest UD website at click on “Rate Order.”

The bottom line – water remains one of the best values we enjoy today. In view of the rising costs, the most effective way for everyone to keep their water costs low is to conserve this precious resource. The cost of water in the future is going to grow. The Board asks that you please read and consider the water conservation materials that we include as inserts in our mail-out bills, on-line at our web-site and as articles in the Prestonwood Press.

Why Does the Cost of Water Keep Going Up? (PDF)

Prestonwood Forest Utility District Water Sources

Since the development of Prestonwood Forest subdivision our drinking water has come from two wells drilled into a major aquifer system underlying most of the Houston area. Typically these wells have provided up to one million gallons of water a day during peak demand. However, with the realization of significant subsidence in the Houston area it has been mandatory that all water entities in the area convert to surface water. Subsidence is a significant problem even in our area. The Fm-249 and Fm-1960 area has subsidence of about four feet.

Regional Map of Area Subsidence (PDF)

To minimize subsidence the area needs to stop pumping water from underground aquifers and begin using surface water. The city of Houston has already begun to do this.

Currently the city of Houston obtains about 80% of its water from surface sources. Beginning in early 2011, Prestonwood transitioned from 100% ground water to about 30% surface water and 70% ground water. By 2020 we will need to be on 70% surface water and by 2030 we will jump to 80% surface water. All of this transition takes time and money and is financed by the fees water customers pay to the Northwest Harris County Regional Water Authority (NHCRWA). For Prestonwood Forest Utility District Customers the fee is currently $2.00 per thousand gallons of water. This fee is subject to change and may increase in the future.

This surface water that NWHCRWA uses comes from Lake Houston via Lake Conroe. Water is drawn from Lake Houston by the city of Houston’s northeast water plant, treated, and 31 million gallons a day are delivered to the North Harris County Regional Water Authority’s Spears Road plant. From here it is delivered through a pipe line system to various water districts in north Houston. Prestonwood Forest Utility District receives about 300,000 gallons each day. This volume is supplemented by water from our two wells, treated, and distributed to customers in the district. As we began to use more and more surface water the city of Houston will expand their NE water plant to accommodate the increased volumes to NHCRWA.

The city of Houston has planned for future water supplies beginning back in the early 1950s. The city currently has water rights to 100% of Lake Houston, and 70% of Lake Conroe and 70% of Lake Livingston. They currently take water from the Trinity River for the Southeast Water Plant as part of their Lake Livingston water rights. In addition, a future project called Luce Bayou (named for its proximity to Luce Bayou) will divert some 300 million gallons of water a day from the Trinity River to the city of Houston’s Northeast Water Plant. From this total, up to 159 million gallons of water a day will be sold to NHCRWA and support surface water conversion and growth in north Harris County. The Luce Bayou is projected to begin deliveries to NHCRWA on July 1, 2019.

While normal rainfall in Houston is about 47 inches per year, from 1951 through 1957 the average rainfall in the Houston area was only 36 inches and other parts of Texas were even more severely limited. From 2002 to 2010 the Houston area averaged about 53 inches of rain a year, well above normal. But over the last three years we have been below normal by one inch, 5 inches, and 25 inches (2011 so far).

For 2011, the total rainfall so far is significantly lower than any previous year. With this lower rainfall level, lakes and aquifers are not being recharged as in the past. While we hope that “normal” conditions might return next year, the forecast is for a warmer and drier winter and probably another very dry summer. We may have to get use to dead trees and brown lawns, something that will surely challenge us all.

When you read about Lake Conroe or Lake Houston being lower than normal it is because of the drought and because of the conversion to surface water in the Houston area. And it’s also a warning that water usage and costs are going to be different in the future. Today, Lake Conroe is down about 10 feet from normal levels. This doesn’t sound like much for a lake 200 feet deep, but 10 feet off the top of Lake Conroe reduces the total volume of the lake by 40%. Furthermore, with lower rainfall levels our lakes are being used up and water tables in the aquifers are also dropping.

We need to think seriously about water usage during the coming months. Part of this will certainly be some type of water restrictions. Even though the water district has adequate water resources it doesn’t mean we can use water indiscriminately for any and all purposes. We want to encourage water conservation and through a combination of education, restrictions, and costs we hope to reduce both ground water usage and overall total water demand.
