WHAT'S AT STAKE
From scale-forming tap to ultrapure feed.
Hardness minerals, dissolved solids, and particulates can contribute to scale, fouling, and corrosion risk in sensitive equipment. Drag to see what high-purity processing removes. The numbers fall as the water clears.

MATCH THE SPEC
The right grade for the system it feeds.
We tailor output to your equipment. Typical targets by application below. Final spec is set to your manufacturer and compliance requirements.
| Application | Grade | Resistivity | TDS | Standard |
|---|---|---|---|---|
| Data center cooling / makeup | High-purity R.O. | 1 – 10 MΩ·cm | < 10 ppm | OEM spec |
| Sterilizers / CSSD | D.I. + R.O. | > 1 MΩ·cm | < 5 ppm | AAMI ST108 |
| Dialysis support | R.O. + polish | — | < 2 ppm | ISO 23500 |
| Lab reagent / analyzer feed | D.I. polish · Type I | 18.2 MΩ·cm | < 0.1 ppm | ASTM Type I |
| General lab | R.O. + D.I. | > 1 MΩ·cm | < 1 ppm | ASTM Type II |
| Pharma purified water | R.O. / D.I. | > 1 MΩ·cm | < 1 ppm | USP <1231> |

CAPABILITIES
A complete high-purity water system.
One owner-led team across treatment, service, delivery, and regeneration. Systems configured to support laboratory, healthcare, and industrial water-quality targets, including ASTM D1193 and AAMI ST108 where applicable.
Ultra & Microfiltration
Membrane filtration that reduces fine particulates and colloids before final polish.
Reverse Osmosis
R.O. systems with ongoing service, monitoring, and membrane care.
UV Sterilizers
Chemical-free UV disinfection to inactivate many microorganisms when properly sized and maintained.
Water Softeners
Hardness reduction that helps protect equipment and improve downstream treatment stages.
Wastewater Recycling
Reclaim and reuse process water to cut cost and discharge.
Salt Delivery
Scheduled salt delivery so your softeners never run short.
Membrane Cleaning
Recover flow and rejection with professional membrane cleaning where fouling is reversible.
Drinking-Water Coolers
Point-of-use coolers that reduce jug deliveries and can improve taste depending on source water.

FACILITY AMENITY · SECONDARY LINE
The Alkaline R.O. Water Cooler.
Beyond the high-purity lines, the same R.O. expertise serves your breakrooms and offices. Point-of-use R.O. water with optional remineralization that reduces jug deliveries. No refills to manage, one predictable monthly cost.
- No more jugs. Continuous supply straight from your line.
- Crisp and clean. Multi-stage R.O. with optional mineral remineralization.
- Low monthly cost. Predictable pricing that beats jug delivery.
- Owner-installed. Set up and serviced by the people who built HPWE.
No medical or therapeutic benefit is claimed. Cooler performance depends on source water, installation, filter maintenance, and testing.

WHY HPWE
When water is infrastructure, the supplier can't miss.
Protects critical equipment
Scale, dissolved solids, and microbial risk can damage cooling loops, autoclaves, and analyzers. Documented water-quality control helps keep critical systems running clean.
Engineered for uptime
Same-day delivery and a dual-line regeneration facility help keep you supplied. Downtime is the risk we plan around.
Documented specifications
Resistivity, conductivity/TDS, and other agreed indicators tested and documented to support your compliance records and audits.
Owner-led, end to end
D.I., R.O., filtration, softening, UV, salt, recycling, and coolers from one accountable team. You reach the people who run the plant.
IN THE FIELD
Trusted where purity is not optional.
Real reviews from our Google Business Profile — from labs and industrial accounts to Arizona homeowners.
★★★★★
The customer service has been superior to other suppliers we've tried in the past 30+ years. Quick service and a willingness to help us in times of need has helped us serve our customers well. I highly recommend them.
★★★★★
The water and customer service this company gives is out of this world. They know everything about water and can modify their systems to suit your needs.
★★★★★
We have been very pleased with the service by Rick and his guys. Their service is very prompt — and he's saved us money compared to our last provider.
★★★★★
Dealing with Rick was fantastic — he spent over an hour answering all my questions about water softener systems. I had a system installed at both of our houses, and it was money well spent.
★★★★★
Absolutely terrific home installation experience, start to finish — and the best water ever!
★★★★★
Fast service. High-quality resin tanks. I have referred them to my competition!

QUESTIONS
What buyers ask before they call.
Straight answers on purity, standards, coverage, and turnaround.
Do you really offer same-day delivery and installation?
Same-day delivery and installation of high-purity D.I. exchange tanks may be available across the Phoenix metro for qualified needs. Call before noon so we can confirm availability, tank requirements, service location, and volume.
What level of water purity can you deliver?
Depending on configuration and application, our D.I. polish can target high-resistivity water up to 18.2 MΩ·cm at 25°C, with low TDS. Final targets — resistivity, conductivity/TDS, TOC, microbial limits, silica — should be set by your equipment manufacturer, validated process, and applicable standard.
Which industries and applications do you serve?
We serve commercial, industrial, laboratory, healthcare, dental, and facility applications — including cooling-loop makeup water, sterilizer support, analyzer feed water, R.O./D.I. systems, and point-of-use coolers. Regulated applications require customer-specific specifications and documentation.
What water-quality standards do you build to?
We configure and service systems to support agreed water-quality targets. Depending on the application, relevant references may include ASTM D1193 reagent-water types, ANSI/AAMI ST108 for medical-device processing water, ISO 23500-series dialysis-water requirements, and USP <1231> guidance for pharmaceutical water. Final specifications should be set by your validated process and compliance requirements, and documented on delivery.
What areas do you serve?
Phoenix and the greater Maricopa County metro, including Scottsdale, Tempe, Mesa, Chandler, and Glendale.
How does the D.I. exchange tank service work?
We deliver and exchange D.I. tanks on-site according to the agreed service schedule. Spent resin returns to our facility for regeneration and reuse. Swap intervals are based on water use, source-water quality, system configuration, and monitored water-quality indicators.
