Rainwater Harvesting & Irrigation Service

Tank Renovations and Upgrades

Liner Replacement

Georgia Water Tanks is fully capable and certified to replace your aging liner.

When replacing the liner, ask what else needs to be done to bring your system up to the latest technology. The "state of the art" of rainwater harvesting changes fast.

Seeing how our systems and others' age, helps us make the best recommendations for new projects.

Spray-in Tank Liners

Georgia Water Tanks now offers polyurea spray-in tank liners, for both new and existing water storage tanks. What is polyurea? It's a plural component polymer that can be sprayed on just about anything you want to protect.

Pure polyureas simply have better physical properties than alternatives: higher tensile and tear strengths, corrosion and impact resistance, superior adhesion, maximum wear-resistance, and higher elongation. It's tougher, stronger, and more dependable.

Highlights of Polyurea:

• Dries in seconds

• Cures in 24 hours

• Expands and Contracts

• 100% inert

• No VOC's (environmentally safe)

• Lasts forever (almost)

MarvelShield M395

M395, by Marvel Industrial Coatings, is a fast setting, rapid curing, 100% solids, flexible, aromatic, two-component spray polyurea that can be applied to suitably prepared concrete and metal surfaces. Its extremely fast gel time makes it suitable for applications down to -20f. M395 PW offers a tack-free time of fewer than 60 seconds and exhibits 450% elongation upon curing with 50 Shore D hardness.

Ideal for:

• Concrete tanks and water tunnels

• Static secondary containment walls

• Mobile secondary containment berms

• Structural steel

• Exterior Pipe protection

• Roofing/flooring in extremely abrasive environments

• Water tanks

It is available in formulas suitable for both potable and nonpotable water.

Pump Service and Upgrades

After 30 years in the booster system business, we know pumps. This one was woefully undersized. We replaced it with a pump that made more pressure. Even though the horsepower was higher, we knew that the electrical circuitry was more than adequate.

​This home uses the cistern for both rainwater harvesting and stormwater management. When the tank is full, rainwater must be pumped to the storm drain. If the tank overflows, the parking area and even the basement could flood. So we designed a commercial-grade controller to give the homeowner a more adjustable system, with a manual override. Everybody is happy!

Rainwater Prefilter Cleaning

This Graf filter had a layer of sediment and algae that was preventing any water from entering the cistern. It has the self-cleaning nozzle, but unfortunately it wasn't working.

This Graf filter wasn't set back in place correctly, which left a ridge that could catch leaves. Which it did!

Freeze Repair. . . and Prevention

As a former Raychem heat tracing rep, we know freeze protection!

Rainwater System Improvements

This pump was 6' above the cistern, and they trusted a foot valve to keep prime. When the tank went dry, air would get through the foot valve and the pump would quit. And then the toilets wouldn't flush. We made several improvements to increase uptime.

​We replaced the suspended pump with a submersible pump in the cistern. And repiped the standby water connection so that they could flush the toilets when the power went out. The larger pressure tank also improved pumping efficiency.

Piping Improvements for Higher Performance

Plastic tanks move when water fills them. Solid piping eventually breaks.

We replaced a section of solid pipe with flexible PVC on this DIY project.
