Because the Rio Grande runs dry, South Texas cities look to alternate options for water

Subscribe to The Y’all — a weekly dispatch concerning the folks, locations and insurance policies defining Texas, produced by Texas Tribune journalists residing in communities throughout the state.

EDINBURG — The Rio Grande is now not a dependable supply of water for South Texas.

That’s the sobering conclusion Rio Grande Valley officers are going through as water ranges on the worldwide reservoirs that feed into the river stay dangerously low — and a hurricane that might have quenched the world’s thirst turned away from the area because it neared the Texas coast.

Though a excessive variety of storms are forecast this hurricane season, reduction is way from assured and because the drought drags on.

For now, the state’s most southern cities have sufficient ingesting water for residents. Nevertheless, the area’s agricultural roots created a system that might jeopardize that offer. Cities listed here are set as much as rely upon irrigation districts, which provide untreated waters to farmers, to ship water that can ultimately go to residents. This setup has meant that as river water for farmers has been reduce off, the provision of municipal water faces an unsure future.

This threat has prompted a rising curiosity amongst water districts, water companies and public utilities that offer water to residents throughout the Valley to look elsewhere for his or her water wants. However for a number of small, rural communities that make up a big portion of the Valley, investing thousands and thousands into upgrading their water therapy strategies should be out of attain.

A brand new water therapy facility for Edinburg will undoubtedly price thousands and thousands of {dollars} however Tom Reyna, assistant metropolis supervisor, believes the excessive preliminary funding will probably be price it in the long term.

“We see the future and we’ve got to find different water alternatives, sources,” Reyna stated. “You know how they used to say water is gold? Now it’s platinum.”

For Edinburg, one of many quickest rising cities within the Valley, the necessity for water will solely develop as their inhabitants does. Whereas the town hasn’t confronted a water provide subject but, the continuing water scarcity in South Texas mixed with the rising inhabitants has put native officers on alert for the way forward for their water provide.

The Falcon and Amistad Worldwide reservoirs feed water immediately into the Rio Grande. And whereas water ranges have been low, cities and public utilities have instituted water restrictions that restrict when residents can use sprinkler methods and prohibits the washing of paved areas.

Cities have precedence over agriculture on the subject of water within the reservoirs. Presently, the reservoirs have about 750,000 acre toes of which 225,000 acre toes are reserved for cities.

Of these 225,000 acre toes, every metropolis or public utility or water provide company can buy what are often known as “water rights” which grants them permission from the state to make use of that water.

However with out water for farming, increasingly of the water that they personal is being misplaced simply in transporting the water to their amenities and that’s immediately as a result of lack of water for farmers.

This relationship with the agriculture trade arose as a result of irrigation districts had been created right here first. Cities got here after and since they used much less water, they had been set as much as rely upon irrigation districts.

Water meant for residential use rides atop irrigation water to water therapy crops. With out irrigation water, cities begin to use water they already personal to push the remainder of their water from the river to a water therapy facility. It’s known as “push water.” A lot of that water is misplaced for this goal.

When water ranges on the reservoirs obtained dangerously low in within the late Nineties, the typical metropolis would solely get about 68% of the water it owns as a result of the remaining could be used as push water, in keeping with Jim Darling, board member of the Rio Grande Regional Water Authority and chair of the native water planning group, a subset of the Texas Water Improvement Board.

The board is tasked with managing the state’s water provide.

Darling, a former McAllen mayor, has been making an attempt to get cities to think about methods to extend their water provide.

As cities attempt to mood water demand by issuing restrictions on water utilization, Darling stated public utilities want to consider the drought not simply from the standpoint of managing demand but in addition by rising provide.

Darling has been floating the concept of making a water financial institution of push water in order that water districts can get by with out having to undergo the method of acquiring approval from the state for extra water.

These discussions have been ongoing with the watermaster from the Texas Fee on Environmental High quality, who ensures compliance with water rights. The talks are nonetheless preliminary, however a dialog with the watermaster’s workplace in early July revealed that three or 4 of the Valley’s 27 irrigation districts had been out of water.

“Something needs to be done,” Darling stated.

Edinburg’s proposed water plant continues to be within the early planning phases, however the objective is to stave off water woes by turning their consideration to water sources underground.

Their plan is to dig up water from the underground aquifers in addition to reuse wastewater. The 2 sources of water could be blended and handled by way of reverse osmosis.

Reserve osmosis consists of pushing water by way of membranes, massive cylinders that filter the water. That is executed a number of instances till the water is pure and meets ingesting water requirements set by the Texas Fee on Environmental High quality.

This methodology is not new.

By implementing this observe, Edinburg is following within the footsteps of the North Alamo Water Provide Company, a utility that provides water to jap Hidalgo County, Willacy County, and northwestern Cameron County.

After the drought in 1998, North Alamo turned to reverse osmosis within the early 2000s.

Their amenities presently deal with about 10 million gallons of water per day by way of reverse osmosis which represents one-third of all of the water they deal with. The remaining is floor water from the river however they purpose to change that cut up, treating two-thirds by way of reverse osmosis and have a 3rd of floor water.

“We’ve got that mindset that we have to get away from the river,” stated Steven P. Sanchez, basic supervisor of North Alamo. “We have to start going to reverse osmosis.”

Hidalgo County officers are attempting to take a extra “innovative” method to the world’s water issues.

In April, county officers touted a proposed regional water provide mission, dubbed the Delta Water Reclamation Challenge, that might seize and deal with stormwater for use as ingesting water.

The mission, anticipated to price $60-70 million, began off as a mission to mitigate flooding by drawing water away from a regional drainage system. However now, plans embrace a water plant that might take every day runoff and deal with it by way of reverse osmosis.

“We are the first drainage district to do something like this and of course that’s an exciting thing for us, to be able to do something that’s so innovative and green,” stated Hidalgo County Commissioner David Fuentes who sits on the drainage district board. “But it comes with a lot of obstacles and a lot of unknowns.”

One problem will probably be financing the water plant. Drainage districts are restricted on the bonds they will subject in change for a mortgage. Acquiring funds from the Texas Water Improvement Board would even be an uphill battle since a drainage district doesn’t match the standard metrics {that a} water provide company does.

County leaders made the case for his or her mission earlier than a Texas Senate committee listening to in Might on water and agriculture, requesting that legislative leaders direct the water improvement board to offer the next consideration to tasks like theirs or to offer a grant program their mission would qualify for.

The county drainage district already accomplished a pilot check of the mission and people outcomes are actually underneath TCEQ for overview. They count on TCEQ will give them the inexperienced mild in addition to directions on how one can design the plant and steps they should take to make sure water high quality.

Fuentes stated they count on that overview to be accomplished early within the legislative session, which might give them a greater concept of what they should ask legislators for.

If the mission turns into a actuality, the county would promote to water companies like North Alamo.

In Cameron County, positioned on the east finish of the Valley, the Brownsville Public Utilities Board was additionally motivated by drought circumstances to cut back their dependence on the river. With assist from their companions within the Southmost Regional Water Authority, the general public utilities board spearheaded the development of a desalination facility that additionally employs reverse osmosis.

Regardless of its rising reputation within the Valley, desalination has its drawbacks. The method has confronted pushback from environmentalists over the disposal of the concentrated salts and since the method requires a number of power.

Southmost and North Alamo maintain permits from TCEQ to discharge the focus, or reject water, into the Brownsville Ship Channel and a drainage ditch that flows to the Laguna Madre, respectively.

Representatives for each entities stated the salinity of the focus is lower than the salinity of the our bodies of water which might be receiving that discharge.

“All the aquatic life that’s there, the plant life and everything that feeds off that water is not being harmed at all,” Sanchez stated. “We monitor that.”

Sanchez stated different options could be drying beds, a technique of evaporating the water into sludge, and injecting the water about 20,000 toes again into the bottom.

North Alamo has additionally made enhancements to their power consumption. In Might, the water company upgraded their 16-year-old water filtering tools, lowering the quantity of power used to create the strain to push the water by way of their filtration system.

Sanchez stated reverse osmosis has additionally been extra environment friendly for North Alamo.

Their floor water therapy plant treats about 2.7 million gallons of water every day whereas the reverse osmosis plant treats 3 million gallons. It is also turn into cheaper in the previous few years. Remedy of floor water prices them $1.21 per thousand gallons whereas reverse osmosis prices $0.65 per thousand gallons, in keeping with Sanchez who stated RO would nonetheless be cheaper even with depreciation.

This wasn’t at all times the case, he stated, however the excessive price of chemical compounds is pushed up the associated fee in treating floor water. However the place floor water therapy is cheaper is within the preliminary price to ascertain it.

Sanchez estimated that the preliminary capital funding for reverse osmosis therapy able to treating one million gallons per day would conservatively price about $6-7 million whereas a floor therapy facility of the identical capability would price $3-4 million.

Southmost’s plans to double their plant’s capability would price an estimated $213 million.

Reyna, the Edinburg assistant metropolis supervisor, agreed that the preliminary funding could be the largest price for the town however believes it should find yourself paying for itself.

Not all cities have that as a viable choice, although. That preliminary price could be an insurmountable hurdle for smaller, rural communities that leaves them unable to put money into options. The state might presumably alleviate a few of that price.

Over the last legislative session, lawmakers established the Texas Water Fund with a billion greenback funding that can go to plenty of monetary help packages on the Texas Water Improvement together with one which has by no means had funding earlier than known as the Rural Water Help Fund.

This will probably be extra state funding to assist rural communities with technical help on how one can determine what sort of design and how much help is finest for his or her neighborhood. This may assist them navigate the method of making use of for funding.

Plans for the way the water improvement board will allocate funds to those new monetary help packages will probably be launched in late July.

Sarah Kirkle, the director of coverage and legislative affairs on the Texas Water Conservation Affiliation expects the state will present rate of interest reductions for loans that will probably be used on costly tasks.

Nevertheless, the $1 billion allotted to the Texas Water Fund won’t get very far.

“The needs for implementing this state water plan are something like $80 billion and those are outdated numbers that we’re looking to update in the new water planning cycle,” Kirkle stated, including that the plan would not embrace the price of wastewater or flood infrastructure.

She famous that the price of water infrastructure is about two or thrice what it was earlier than the COVID-19 pandemic due to disruptions within the provide chain and extra federal necessities for federally-funded tasks.

Many small communities additionally do not have the sources to plan for his or her wants, Kirkle stated, so lots of them do not take part within the water planning course of, leaving nobody to talk up for them.

“We really need to make sure that as we see additional water scarcity around the state, that our communities are engaged in planning for their needs and understand where they might have risks and where their water might not be reliable,” Kirkle stated.
