Installations that our greater than 1,000 gallons but less than 5,000 gallons.

This page represents "medium" sized systems and a few examples are shown below.  Each installation is different.  The cost can vary widely.  Tanks, PVC pipe and fittings, filters, and pumps have straightforward costs.  You can go to any rainwater harvesting distributor online and get a good sampling of costs.  The biggest cost driver is site preparation.  If the cisterns have a flat stable surface to sit, then typically there may be little or no cost to prepare the site.  However if an area has to be dug out and a retaining wall installed this will incur additional costs.  The key elements of a good system are-
1) Sufficient roof area to collect from.
2) A good pre-filter and first flush prior to the cistern.
3) A UV protected plastic used in the construction of the cistern you choose.
4) An inlet and overflow sized to the amount of water flowing from the roof collection area
5) A means of distributing the water via gravity or pump.

This is a 4,320 gallon system in Carmel Valley. The primary 1,320 gallon Bushman tank collects rainwater from the roof and then pumps up to two 1,500 gallon tanks that can gravity flow water into the yard.

This is a 3,000 gallon system in Carmel. A submersible pump is used to provide water to irrigate the landscape.

This is a 2,200 gallon system in Pebble Beach with a pump. The water is used to irrigate plants around the home. The tanks are low profile and sit below the top of the fence where neighbors won't see them.

This is an 1,100 gallon system installed at Walter Colten School in Monterey. Water will gravity flow down to the Science Class garden.

This is a 1,260 gallon system placed under a stairwell in PG. A pump will be used to irrigate plants via a drip system.
