Rain Collection Systems

A professionally installed rain collection system is one of the simplest and most effective ways to conserve water while keeping your yard green and healthy. By capturing rainfall from your roof and storing it for future use, rainwater harvesting turns a natural resource into a reliable, eco-friendly irrigation supply.

With rising water costs and hotter, drier summers in Spokane, more homeowners are turning to rainwater harvesting systems as a smart, sustainable solution. These systems not only help reduce your water bill but they also support healthier soil, plants, and lawns without relying solely on municipal water.

At Greenscape Landscaping, we design and install complete rain collection systems, customized for your home and landscape. From rooftop catchment to storage tanks and integrated irrigation, we handle every step to ensure long-term performance and efficiency.

What Is a Rainwater Collection System?

A rainwater collection system is designed to capture, store, and reuse rainwater, typically from your home’s roof, for irrigation, landscaping, and other non-potable uses. These systems are an increasingly popular solution for Spokane homeowners looking to conserve water and lower utility bills while keeping their yards healthy and green.

Here’s how it works: as rain hits your roof, it’s directed through gutters and downspouts into a connected system of diverters, filters, and either a barrel for rainwater or a larger storage tank. The water is then stored safely for later use during dry periods, reducing your reliance on municipal water systems.

The most basic setups use a single rainwater collection barrel, ideal for smaller areas like flower beds, container gardens, or manual watering. These are easy to install and perfect for beginners or eco-conscious homeowners taking the first step toward rain collection.

More advanced rainwater capture systems include features like underground cisterns, UV filtration, automated irrigation, and booster pumps, allowing you to efficiently water large lawns or entire landscapes—all with naturally collected rainwater. These systems can be customized to fit your roof size, water needs, and property layout.

Whether you’re looking for a simple DIY solution with a rainwater collection barrel or a fully integrated rain collection system connected to your irrigation lines, these systems offer a sustainable, low-maintenance way to make better use of every drop while protecting both your landscape and the environment.

Benefits of Rain Collection

Installing a rainwater harvesting system offers more than just water savings, it’s an investment in your landscape and the environment. Here’s how Spokane homeowners benefit:

  • Cut down on water bills and city water use: Reduce your dependency on municipal water, especially during irrigation season
  • Supply eco-friendly irrigation during Spokane’s dry months: Keep your garden and lawn thriving, even during watering restrictions
  • Reduce runoff and soil erosion: Capture roof runoff before it floods your yard or foundation
  • Help meet sustainability goals or qualify for water conservation programs: In some areas, rebates may be available for approved water catchment systems

Our systems include high-quality rainwater harvesting tanks and rainwater storage barrels designed to maximize capacity while fitting seamlessly into your property. Whether you’re focused on conservation or cost, rain collection is a smart upgrade with long-term returns.

System Design & Installation Services

At Greenscape Landscaping, we specialize in designing and installing complete rainwater collection systems that are tailored to your home, yard, and irrigation goals. 

Our approach goes beyond just setting up a barrel; we deliver smart, efficient systems built for long-term performance and water savings.

We begin with a site consultation to assess your roof area, landscape layout, and typical water usage. This helps us design a system that captures the right volume of rain and stores it in the most effective way for your needs, whether that’s a discreet barrel for rainwater near a garden bed or a large, underground rainwater harvesting tank integrated into your sprinkler system.

Every system we install includes the core components necessary for clean, functional storage and easy access:

  • Rainwater storage solutions: From compact decorative barrels to high-capacity above- or below-ground tanks
  • System plumbing & controls: Including downspout diverters, sealed piping, and overflow protection
  • Optional upgrades: First-flush filters for cleaner water, pumps for pressure, and irrigation system tie-ins

We take care of everything from system planning and product sourcing to excavation, plumbing, and testing. Our team ensures that your system functions properly, looks great, and complies with local guidelines.

With Greenscape, you get more than just a water-saving solution, you get a professionally designed and installed rainwater collection system that fits your landscape and your lifestyle.
