Drip Irrigation – Home Irrigation Part 3

Before we get started, here are the latest watering restrictions from the City of Rockport’s website. Drip irrigation is allowed any day at all stages below until Stage 3 is reached.

Current Status – Voluntary
“In accordance with the City’s Drought Contingency and Emergency Water Plan, customers of the city’s water system are asked to cut back on water usage from May 1 – September 30 by voluntarily watering once a week. The revised water conservation plan also prohibits watering between the hours of 10 am and 6 pm anytime throughout the year. Residents with water wells are not required to comply with the prohibition of watering between 10 am and 6 pm but are encouraged to do so.”
Current (7/31/2019) water combined water levels for the area are at 64.5% full (from sanpatwater.com/home.php).
• Stage 1 restrictions start at 40% with once a week lawn watering on the designated day (ending house number even is Tuesday, odd is Wednesday, multifamily/commercial is Thursday).
• Stage 2 begins at 30% with watering once every other week.
• Stage 3 begins at 20% and all lawn/landscape watering is prohibited.

Drip irrigation originated in 1965 in the Negev desert in Israel by the Netafim Company which is still a leader in this type of irrigation. The bulges in the tubing are caused by a sophisticated flow control device which allows constant and even dripping in the first foot of tubing to the last, unlike soaker hose. Some characteristics of drip irrigation are:
⦁ Water-conserving – Water goes to the plant and not into the air.
⦁ Easy to work – Tubing can be cut with scissors and connected by simple barbed fittings. Kits are available.
⦁ Uses reduced pressure – Drip uses water pressure reduced from tap levels of about 60 psi to about 25 or 30.
⦁ Great for vegetables and landscape plants. Not great for lawns.

Let’s build a drip system.

Here’s a drip system for plants in pots or hangers. Sourcing is from Amazon but similar items can be found at Lowe’s, Home Depot and sprinklerwarehouse.com.

I’m giving a talk at the AgriLife center (801 Airport Blvd) Tuesday Aug. 20 12 noon to 1:00 which is based on this article and we’ll be building the drip system.
