Overview of Rainwater Collection Objectives

Our focus is to insure water quality by utilizing the area’s abundance of rainfall.  This water will not make contact with the ground; therefore, eliminating pesticides, herbicides, iron, calcium, magnesium, heavy metals and other substances. Interested? Fill out this form to receive a free quote for a rainwater system for you home or land.

You will be in control of your water supply at all times.  Instead of adding chlorine, the natural U.V. light will act as a disinfectant. Fluoride is ideal in mouthwash and toothpaste but certainly not intended as a part of drinking water!  

For you to use during municipal down times or the occasional accidental contamination periods, we will install a large storage vessel for your reliance. This leaves municipal water supply as a back-up.

By rainwater not having calcium or magnesium this eliminates the worry of prematurely replacing appliances such as the water heater, dishwasher, ice maker, and plumbing fixtures due to erosion.

The water filled storage tanks serve as fire protection, and could help lower insurance premiums by a great deal. (Check with you agent.)

The amperage load for the pumping system calculates a much lower cost per gallon of water delivered as compared to municipal supplier charges.  The rate of a supplier is likely to increase periodically.  In the event of a power failure, a small generator will run the pump to keep in pressurized water.  You can be off the grid!

F.A.Q. (Frequently Asked Questions)


• About 550 gallons per 1000 sq. ft. of roof space


• About 1600 sq. ft. will do for two people


• From 3500 to 5000 gallons per person


• Storage tanks are sized to allow 75 to 90 day droughts
• Water deliveries are available


    1.You will have no doubt of water availability in the future (approximate annual rainfall of 32 inches per year in the Central Texas region). In the past, land owners have spent thousands of dollars only to find a malfunctioning well due to lack of water.

    2. You will have a known and consistent quality of water.

    3. You will never have to pay for a service truck to pull a pump out of a well and replace it. The cost can be over $2,000.00 and nation wide the life of the pump is only five to seven years.

    4. The needed water treating system is included in the price. (no surprises after installation).

    5. Initial cost of installation is comparable.

    6. Much lower recurring maintenance costs.

    7. Much lower cost of elec. Power to operate.

    8. New legislation passed: YOU PAY NO SALES TAX ON SYSTEM.  In 2001, the 77th Legislature of State of Texas passed Bill 2 exempting rainwater harvesting equipment and supplies from state sales tax.  www.capitol.state.tx.us

    9. Some counties now offer $100.00 rebate on property development fees.  Hays county was among the first to provide a Rainwater Collection Incentive Program including tax exemption of 100% of the cost.

For centuries, people have relied on rainwater harvesting to supply water for household, landscape, livestock, and agricultural uses. Before large centralized water supply systems were developed, rainwater was collected from roofs and stored on site in tanks known as cisterns.

With the development of large, reliable water treatment and distribution systems and more affordable well drilling equipment, rain harvesting systems have been all but forgotten, even though they offer a source of pure, soft, low sodium water.

A renewed interest in this time-honored approach has emerged in Texas and elsewhere due to:

  • * the escalating environmental and economic costs of providing water by centralized water systems or by well drilling;
  • * health benefits of rainwater;
  • * collection systems

Types of Tanks


These fiberglass tanks are the best value because they are custom-built to order with all the fittings needed for one's particular application. (most all are different) Unlike poly tanks,  no special adaptation is necessary. If fiberglass tanks become damaged, they are easily  repaired;  the same cannot be said for poly or concrete. Also are very nonporous and leave no taste residue in your water. They are coated with a U.V. inhibitor and are available in many colors.

Examples of installed Rainwater Collection Systems

Garfield - Top of the Line System

The first example is a very large system using the very best of everything that we offer. Location is near Garfield off hwy 71 and Wolf Lane. It was designed large enough to provide water for both a large shop with live-in apartment and a sizeable home with pool and Jacuzzi tub. It is really two systems in one.

The shop and apartment was 185’ by 45’, over 8,000 square feet of catchments area. The downspouts shown are 3” pipe. Because there were a number of them, we had to bury a 6” trunk line around the front of the building to the rear for delivery to the tanks.

We dedicated about 75% of the roof area to the first tank holding nearly 20,000 gallons of water. This water is to be delivered to the home site just about 100 feet away from the shop area. The remaining roof space goes into the smaller tank holding 5,000 gallons, and is for the apartment and shop use.




The roof washer allows the water to enter low in the box and then rises up through a screen. It then empties into the tank. The screen catches such things as leaves, bugs, and other debris that can accumulate between rain showers. These things are periodically drained away through a 1 ½ “ flow line out the bottom of the box. Once in the tank, the water does not become stagnant over time because no light is allowed to penetrate at any point. Bacteria cannot colonize and grow without light.

Pictured below, we used two demand type computer driven pumps that deliver constant pressure and yet require no pressure tank.

Our filter system is a small rack of very effective equipment. This makes a much cleaner install than a wall or floor full of individual separate components. First is a 5 micron sediment filter, then carbon to remove organics and improve taste, and last if Ultra Violet light for disinfection. The cost of purchasing and maintaining this equipment if fractional in comparison to a submersible water well pump and the massive treating systems usually needed.

Different Systems to Meet Different Needs

snyder tanks This is a 10K gallon system with poly tanks. My Snyder tanks are not like the ones you see at the farm and ranch stores. They have a much higher specific gravity and so you will not see the dome tops cave in like the ones you have seen. They are thicker and stronger and available only through Browns Water well.

Money Saving Tip

A recent Rainwater Collection System installed near Smithville


This is a simple and inexpensive system that will serve two people in the soon to be built home near Smithville.  We used two downspouts, one at each end of the barn, and a 4” trunk line to the roof washer box located at the top of the first tank.

The two tanks are joined at the bottom with three valves that allow us to use the tanks in conjunction with each other or separately. They also are joined at the top with an overflow from the first to the second with a 2” pipe. Each tank has one 1 ¼ vent with screen for mosquitoes and a 2” overflow with screen.

The pump is installed in the barn. We placed it under a sink to save room in the storage area. The pump is a demand type, computer driven booster and does not require the use of a pressure tank. This saves space and money. The system does not include the filter system for drinking water, that equipment will be added later at the home nearer the point of use.

The cost of the entire system was less than $10,000.00. In this particular area this is about $5,000.00 less than a well with treating system. Because the water in the area is deep, well drilling is often costly.

As a result of this satisfied customer, we will be providing a similar system to the neighboring property for a family member in the very near future.

System installed in Cedar Creek

Our customer had a desire to be totally off the grid for delivery of her water to her home. It is a relatively inexpensive installation using two 5,000 gallon poly tanks and a first rinse roof washer just made of a smaller tank that she partially drains after or before an episode. Then she pumps the water to the home using a solar powered pump through the same filter system that we usually use. Pretty Cool!

The first vertical tank catches the very first water off the roof and when it fills to the point where the water enters then water flows to the holding tanks free of leaves and other debris. The customer occasionally drains  a determined amount of water out of the primary tank and it is ready  for the next shower The two large holding tanks are joined with 2” plumbing at the bottom so that they keep the same level of water in both at all times.





The solar pump is tucked away in the previously existing shed along with a small pressure tank. There are also included two batteries kept charged by the p.v. panel so that  water can be used in the evening and early morning for showers and cooking etc. This customer does not depend on the local rural water supplier nor the rural power company for delivery of her water! She is completely in control of her water quality and availability.
