With First-Ever Colorado River Shortage Almost Certain, States Stare Down Mandatory Cutbacks

The Colorado River’s biggest reservoirs are likely to drop to historically low levels later this year, prompting mandatory conservation by some of the river’s heaviest users.

The latest Bureau of Reclamation reservoir projections, which take into account river flows in a given year, show a likelihood that Lake Mead on the Arizona-Nevada stateline will dip below the critical threshold of 1,075 feet in elevation in May and remain below that level for the foreseeable future.

A first-ever official shortage declaration from the Department of the Interior is almost certain later this year. According to the terms of a 2007 agreement, a shortage is declared by the Interior Secretary after consulting with water users in the Lower Basin states of California, Arizona and Nevada. An August report is used to forecast when Lake Mead will be below 1,075 feet at the start of a calendar year.

Water Reuse Projects Highlight Sustainable Building Week

Three potable water reuse or recycling projects under development in the San Diego region were highlighted this week during the San Diego Green Building Council’s inaugural “Sustainable Building Week San Diego.”

The Sustainable Building Week programs focused on sustainable practices and creating collaboration and networks among San Diego professionals involved with environmental stewardship and green building.

12 Grand Groundcovers to Use as Lawn Substitutes

You’ve decided to eliminate the thirsty turf areas in your current landscaping when planning your new sustainable landscape. It’s tempting to install hardscape. It needs no water at all. It might seem like a smart idea, but it creates a new problem: stormwater runoff. It can also increase temperatures and add in its own small way to global warming.

Finding alternatives to cover the area with plants instead of hardscaping will help prevent too much stormwater runoff and capture rainfall.

Consider replacing your lawn with groundcovers. There are many good choices of groundcover plants that make good lawn substitutes. Many species grow well in San Diego County’s six climate zones and the Mediterranean climate natives fall into the very low or low Plant Factor categories. They won’t use as much water than the same amount of grass.

Very Low Plant Factor groundcover choices include:

Extreme Conditions Now Sparking Drought Contingency Plan for First Time

Extreme drought conditions throughout the West are lowering levels in the crucial water reservoir, Lake Mead. Scars of long years of low precipitation are hard to go unnoticed at Lake Mead, and the hot, dry summers have been felt for the last several years in Arizona. 2020 was especially dry, with little monsoon. Now, the West is in uncharted territory. Lake Mead is projected to drop by several feet this year, from elevation 1,083 to about 1,068, according to officials with the Central Arizona Project. The lake is hovering around 39 percent of its full capacity.

Western U.S. May Be Entering its Most Severe Drought in Modern History

Extreme drought across the Western U.S. has become as reliable as a summer afternoon thunderstorm in Florida. And news headlines about drought in the West can seem a bit like a broken record, with some scientists saying the region is on the precipice of permanent drought.

Las Vegas Pushes to Become First to Ban Ornamental Grass

A desert city built on a reputation for excess and indulgence wants to become a model for restraint and conservation with a first-in-the-nation policy banning grass that nobody walks on.

Las Vegas-area water officials have spent two decades trying to get people to replace thirsty greenery with desert plants, and now they’re asking the Nevada Legislature to outlaw roughly 40% of the turf that’s left.

The Southern Nevada Water Authority estimates there are almost 8 square miles (21 square kilometers) of “nonfunctional turf” in the metro area — grass that no one ever walks on or otherwise uses in street medians, housing developments and office parks.

SD Sustainable Building Week Features Water Reuse Projects

Representatives from three potable reuse projects currently under development in San Diego County will participate in the inaugural “Sustainable Building Week San Diego” at 11 a.m. on Tuesday, April 13.

Hosted by the San Diego Green Building Council, Sustainable Building Week offers free virtual events from April 12 – 16 addressing sustainable practices and creating collaboration and networks among San Diego professionals involved with environmental stewardship and green building. All events are free and open to the public.

Successful Sustainable Landscaping a Click Away for Helix, Padre Dam Customers

No matter whether their landscaping is just a few square feet alongside a front porch or estate acreage, thousands of San Diego County residents have learned to embrace sustainability as a central principle for creating and renovating their landscapes.

Thanks to financial incentives and educational resources offered by the San Diego County Water Authority to customers in La Mesa, Lemon Grove and El Cajon, a sustainable and beautiful yard is more attainable than ever before.

SNWA Wants Nevada Legislature to Consider Legislation to Remove All Unused Turf Throughout the Las Vegas Valley

Some big moves are coming from the Southern Nevada Water Authority. The water company wants all “unused turf” (grass) in the Las Vegas valley remove

The agency sent the following tweet expressing the legislation it would like to see proposed on Monday night.

This is Water Infrastructure

The water industry has a visibility problem. Often the only time that water professionals are contacted is when things have gone wrong.

Calls come in when a pipe bursts. Angry emails from a local homeowners’ association detail how sewers are backing up in basements. Lawsuits are filed when contamination is found in drinking water.

If you followed the news, you would think there are only problems and few successes with water infrastructure in the U.S. But that’s not the case. Part of the visibility problem with water infrastructure is that the industry does such a good job of making things work. In most situations things are not falling apart. Contamination is not an issue. Sewage backups are solved or eliminated, and people spend their game day blissfully unaware of the infrastructure keeping their finished basement dry.

These are successes we tell ourselves within our bubble, but they aren’t told to a wider audience. It is time to change that.

There is beauty and art in the engineering of these systems. Whether it is an array of aerators for a new mixing tank, the reflection of the sunrise in an open-air clarifier, or the organized jumble of purple pipe at a water reclamation facility, water infrastructure is not invisible. It’s right there.

Below is a growing and updated list of examples of water infrastructure throughout the U.S. Tag @WWDmag or @BCrossen on Twitter with your pictures of your infrastructure to be included in this ever-evolving and growing list. Or send an email to  with the subject line “This is water infrastructure” with your location, facility name and what you admire about your local infrastructure.

A Water & Wastes Digest story said the water industry has a visibility problem with infrastructure. The magazine article featured this San Diego County Water Authority tweet, among others, on April 2, 2021.
