First, I have a drip system installed. But the water is full of sand and it gradually clogs the drippers. Also, the easy to find tubing only lasts about 5-6 years. Just got 500 ft of blue line hose, which has greater UV resistance, but it takes a ton of work to put it in. Also bought 50 new drippers. The best way to do drip is run buried PVC with risers with half inch hose running out from there, preferably buried. Back yard is 256 feet by 125 feet, and there are about 1500 feet of pathways, so you can see that a lot of digging is involved. The drip tubing lasts far longer if buried.
The water rights here are owned by a much hated Canadian investment group who have basically bribed the Democrap PUC to guarantee it a profit--we pay about $50 a month to guarantee that profit. So it is the most expensive water in California. The city is trying to re-take the rights, but the Canadians are running up the bill with challenges and delays. A leak can up the bill from $100 a month to near $450. Have had to let a lot of plants die off. Hate seeing my landscaping die, but I'm no longer able to afford that kind of bill.
There are a few varieties of trees that hold up pretty well despite drought, but they're pretty sparse and don't cast much shade. So the toddies get consumed on the patio or office shed porch. By mid summer, all consumption occurs under Air Conditioning.
The more I do, the less I accomplish.
