Completing the Underground Connections for Our Water Catchment System

Although relatively inexpensive today, we believe that water is a very important resource and we would like to be exemplary in our use of water.  Our strategy is to reduce our demand for water and then to supplement the demand for irrigation by utilizing water from our underground cistern.  We will capture 100% of the rainwater from our roof in our underground cistern.  All water pumped from below our foundation will go into our underground cistern.

Oh, we had a nasty thorn removed from our side today when, after considerable prompting, the SAM storage unit was finally removed at 5:30 pm this evening.

Completing the Underground Connections for Our Water Catchment System

The key piece of infrastructure that we need for the water catchment system from our roof and hardscape is the connection pipes to our underground cistern.  Bryan has been focusing on the various elements that will go into our trenches for the past month and it is now coming together nicely.

Essentially, the perimeter of the entire house has a network of drains, all of which are connected and empty into our 3,677 gallon underground cistern.  Our lower flat roof, to which all of the roofs drain to, has seven (7) drains that must, ultimately, connect to our underground cistern.  In addition to these 7 roof drains, there are 12 other drains around the property that take water via the water catchment system to the underground cistern.

As of today, we have all of the drains in place around the entire property, with ‘stubs’ to to each of the surface drains (on hardscape and otherwise).  This water catchment system needs to be connected to the underground cistern next week.

Testing Our Geothermal Ground Loop

The two-person team from 88HVAC, Justin and Mike, continued to work diligently today as they tested our geothermal ground loop.  Well, to be accurate, our four geothermal ground loops.

We have 13 concrete piers on the East side of the house and 12 piers on the West side of the house.  These 20-inch in diameter concrete piers go 30 ft into the earth and are on 5 ft centers.  There are two U-tubes of 3/4-inch HDPE in each concrete pier, going the full length of each pier.

Of the 25 concrete piers, there were problems with one of the two U-tubes in two of the piers.  The problems were isolated to two specific U-tubes and, fortunately, Bryan was able to resolve one of the problems today.  The problem with the remaining U-tube may not be resolved, which leaves us with a ground loop of 2,940 ft (without the problem would be 3,000 ft).

Removing the Nasty Thorn in Our Side (i.e., the SAM Storage Unit)

At 5:30 pm, a truck arrived and picked up the offending SAM storage unit from Winchester Boulevard.

Bryan had called the company earlier today to request that the SAM storage unit be removed.  Actually, he called twice today.  On the second call, Bryan was able to refer to our blog entry from yesterday so the call center person could actually see the problem first hand.  He advised the call center agent that immovable objects require a permit to be on the public right of way (i.e., street) and the Town of Los Gatos had not issued a permit for the SAM storage unit.

It was good to see the SAM storage unit leave our neighborhood.
