PRESSURE REGULATION SAVES WATER & MONEY

Historically, most irrigation systems have non-pressure regulated sprinklers that often times operate over-pressurized. Over-pressurization can lead to water losses and contribute to uneven watering.

Pressure-regulating spray heads are a developing technology designed to regulate pressure for optimal performance. Pressure-regulating spray heads include built-in regulators that maintain a more constant pressure for optimal nozzle performance.

WHY IS PRESSURE REGULATION IMPORTANT?

Two reasons: They will save water and it is likely soon to be the law. 

WATER SAVINGS:  Compared with non-regulated, pressure regulated sprinklers will use about 20-25 percent less water. If the nozzle breaks, pressure regulators are estimated to save 70% of the water that might have been spilled compared to older sprinkler systems.

Many states including Washington and Oregon require pressure regulation. Since March 1, 2022, Oregon requires PRS. While government regulations are frustrating, these actually make real sense.

SAM-PRS Spray Heads

We are converting our spray head inventory to those with Pressure Regulation (PRS) and Check Valves (SAM). As mentioned above, PRS is becoming the law, but both PRS and SAM save water.

• Built-in PRS pressure regulator maintains constant outlet pressure at 30 psi, ensuring maximum nozzle performance even with varying inlet pressures. Saves 20-30% of water compared to standard heads.
• Restricts water loss by up to 70% if nozzle is removed or damaged.
• Built-in Seal-A-Matic™ (SAM) check valve eliminates low head drainage from spray heads located at the base of slopes or hillsides.

As part of our water conservation initiatives, we will be recommending replacing spray heads with SAM-PRS heads to save 20-30% in water use and cost.

MP Rotator

MP Rotator is a revolutionary alternative to traditional sprinkler heads and pop-up sprinkler heads that spray the landscape. MP Rotator nozzles feature unique, multi-trajectory rotating streams that deliver water at a steady rate. This slower application rate allows water to gently soak in at rates that soils can absorb.

As part of our water conservation programs, we will be recommending replacing some spray heads with MP Rotators for even more water savings of up to 40%.

WATER CONSERVATION MAKES FINANCIAL SENSE

The average price for water in the Portland Metro area has increased from 64% to 373% over the past 5 years. WATER RATES ARE THE FASTEST GROWING UTILITY COST IN THE PORTLAND METRO AREA!  Water Conservation has great ROI.
