There are safer alternatives to waste water pipelines and "tank farms"

Currently there are safer and greener alternatives for recycling and treating produced water than piping it under our town to a tank farm.
Other gas companies are using the systems below with great success.

The advantages
Less trucks bringing fresh water to site for fracking because the units can reclaim 70% or more of the waste water and reuse it.
Less trucks to haul away what little waste water is left over.
No need for underground pipelines and tank farms.
They are on site systems and are mobile so it can be relocated to another site.

If Williams cares about being a good neighbor, than why did they not propose this type of system?

See info below
a few paragraphs from article

STW's semi-permanent installations can process up to 17,142 barrels or 720,000 gallons per day. STW's mobile units give it the ability to move the processing of fracture water from well site to well site. At this time, Devon Energy is evaluating STW's water processing technology for use in some of its drilling and production operations.

The first project will utilize technology developed by GE Water & Process Technologies to reclaim approximately 70% of the fresh water from highly contaminated oil and natural gas hydraulic fracture flow-back water and salt water that is produced in conjunction with the production of oil and natural gas.

Here is another company with mobile on site recycling and treatment
a few paragraphs with links to their brochure

Historically, produced water generated at an oil or gas site is stored on-site in large tanks. Oil and gas companies must pay for disposal trucking companies to visit the site multiple times per week, pump the produced water out of the storage tanks and transport the waste to commercial underground reinjection sites. These disposal trucks must often travel great distances to the reinjection sites. When these trucks are unavailable or during periods of poor weather, many well sites must be shut down due to the inability to store and/or dispose of the produced water onsite.

some info on cost for this type of system

In addition, many oil and gas wells are simply “pinching back” production due to inability of onsite infrastructure to handle produced water volumes. Trucking costs alone can be in excess of $3 per barrel (bbl) and a disposal reinjection well can cost upwards of $4 million to drill. In many locations, total produced water disposal costs are greater than $5/bbl. Stated differently, the oil & gas industry spends as much as 80 times as much, per gallon, to get rid of dirty produced water as individuals pay for clean municipal water. Despite considerable efforts and investment, there were no cost-effective technological solutions available to reduce the huge disposal costs of this highly-brackish produced water, until now.

AltelaRainSM lowers the cost of oil and gas production while dramatically decreasing the volume of waste that needs to be trucked away and disposed. It purifies the most highly-challenged water using energy produced at the wellhead, in a simple, mobile and modular system located on-site. More on the AltelaRainSM System
