RAINWATER 

Just an inch of rainfall captured on 1,000 square feet of roof area can provide over 600 gallons of water. Don't let that rainwater go to waste and offset your need for municipal water!
Capture rainwater in above or underground  tanks for use in irrigating the landscape, replenish your groundwater with a rain garden, and/or pump the rainwater to indoor plumbing for flushing  toilets and washing laundry .
Solve seasonal flooding issues by controlling the water before it causes problems.  
We can mix and match options to build a fully customized rainwater harvesting system for your property. 
Save rainwater on-site for emergency use in case of fire or earthquake.
​
With proper filtration and sterilization, rainwater can supply a home with potable-quality water throughout the year.
Rainwater is suitable for all plants, including vegetables. 
Most systems under 5,000 gallons do not require a permit.
​
No permit required up to 5,000 gal; 
CH.1603.1 A permit is not required for exterior rainwater catchment systems used for outdoor non-spray irrigation with a maximum storage capacity of 5000 gallons where the tank is supported directly on grade, the ratio of height to diameter does not exceed 2:1 and does not require electrical power or a make-up water supply connection. No permit required for systems up to 360 gallon capacity for spray irrigation.
