SERVICES / RAIN HARVESTING
RAIN HARVESTING
Rainwater collection, storage, and pumping systems designed around your site and approved end uses.
RAINWATER REUSE DESIGNED FOR YOUR SITE
Water recycling is important — not just for the environment, but for cutting down water bills. California's ongoing water challenges make rain harvesting a practical and increasingly required solution for residential, commercial, and municipal projects.
We design complete rain harvesting systems using top component brands. From small residential cisterns to large commercial storage and distribution systems, we handle the hydraulics, pumping, filtration, and controls.
Our systems are designed to maximize collection volume, minimize maintenance, and integrate seamlessly with your existing plumbing and irrigation infrastructure.
WHY HARVEST RAINWATER
WATER CONSERVATION
Capture and reuse rainwater to reduce dependence on municipal water supplies and mitigate stormwater runoff.
LOWER WATER BILLS
Using harvested rainwater for irrigation and non-potable uses can significantly reduce monthly water costs.
ENVIRONMENTAL IMPACT
Reduce your project's environmental footprint by minimizing runoff, erosion, and pollution into local waterways.
REGULATORY COMPLIANCE
Support applicable sustainability goals and potential green-building credits, subject to project criteria and review.
APPLICATIONS
LANDSCAPE IRRIGATION
Harvested rainwater stored in above or below-grade cisterns, then pumped on-demand to irrigation systems. Ideal for HOAs, parks, and commercial properties.
TOILET FLUSHING (NON-POTABLE)
Filtered rainwater used for toilet and urinal flushing in commercial buildings — a major water savings application.
FILTERED DRINKING WATER
Potable use requires project-specific treatment, water-quality testing, and approval by the relevant health and building authorities. Filtration and UV treatment alone do not establish suitability.
COOLING TOWER MAKEUP
Large commercial or industrial facilities can supplement cooling tower makeup water with harvested rainwater, reducing costs significantly.
CAR WASH & INDUSTRIAL PROCESS
Non-potable water uses like vehicle washing, dust control, and industrial processes are well-suited for harvested rainwater.
AGRICULTURAL & LIVESTOCK
Rural properties can benefit from large-scale cistern systems to water crops, livestock, and reduce well dependency.
WHAT WE DESIGN FOR YOU
Every rain harvesting system is custom-designed to your catchment area, storage volume, and end-use demands. We provide a complete engineering package ready for permit and installation.
- Cistern sizing (above or below grade)
- Collection and first-flush diverter design
- Pump selection and booster system design
- Filtration and treatment system specification
- Distribution piping and controls
- Permit-ready drawings and documentation
TOP BRANDS WE USE
We source components from industry-leading manufacturers to ensure reliability and longevity in every system we design.
- Grundfos (pumps & controls)
- Rainbird & Hunter (irrigation)
- Wisy (first-flush & filters)
- Hydroflex (cisterns)
- AquaStore (modular storage)
- UV Pure (disinfection systems)
PROJECT EXAMPLES
Commercial Office Park — Rancho Cucamonga
Designed a 50,000-gallon underground cistern system capturing roof runoff for full landscape irrigation, reducing potable water use by 60%.
Custom Residential Estate — Corona
Installed a gravity-fed rain harvesting system with multi-stage filtration providing supplemental drinking water and full garden irrigation.
HOA Common Area — Chino Hills
Replaced a failing irrigation well with a 20,000-gallon above-grade cistern and booster pump system, serving 8 acres of common area landscaping.
