Water filters

Which is why one usually has a proper "home Inspection" done prior to buying a property.
Many properties have NEVER cleaned the cisterns nor have filtration systems installed.
Keep the roof and gutters clean and you will have a cleaner cistern for a longer time plus add clorox.

This cistern was seal and clean in. 2004 and it has a filter system but it looks old and simple .. I just want to upgrade it. so I know I have good water. However I am going to service the cistern again as soon we move . I just trying to learn about about how they doing the thing in the island. Here in Jersey I do every thing myself , but we don't gave too many concrete buildings, every thing is wood.

Trust me, you won't be cleaning the cistern yourself and if on property during this period you will need alternative water supply to bathe, do dishes, shower, flush toilets etc for at least 5-10 days as there is cleaning, pe-caoting and a curing process.
You really don't want to do this when your cistern is full and waste all the water.

I've cleaned my cistern and resealed it myself. 2 days of hard work.

believe me, I dont want to get in that tank, I just said I going to get it service by a professional .. ha ha

You might ask around on the sealing too...I'm not a plumbing professional, but a friend that is told me that he doesn't like the sealant, that it seeps into the water and makes the water slimy, and that the coating doesn't help that much anyway. I have no idea, and if you use a filter maybe it doesn't matter. We had our cistern cleaned four years ago but haven't sealed it in a while with no ill effects.

I'm sure other people here have opinions to share.

thank you .. i guess if we have a good filtration and use chlorine like other people said should be good... if you here more about please let me know , I really appreciate. Jorge

This is why the cleaning, sealing and curing process before putting H2O back into cistern usually takes longer.

That makes total sense. Most people are probably in a hurry to put water in the cistern again.

There is no safe way to clean and reseal a concrete cistern in 2 days -- it has to dry before applying and be washed after applying.
This is why most cisterns are built with 2 compartments - you can clean and seal one without losing ALL your water and still have functioning plumbing during the process.
Many cistern repair/cleaning companies will bring a plastic tank to save some water and use during the process if the cistern is not compartmented - years ago we just rented a water truck for the week and parked it in the driveway while we cleaned but didn't reseal.
The concrete can spall with rusting iron rebar weakening the entire structure if the resealing is not done properly -- with semi-disastarous long term problems down the road. This can require the installation of a custom plastic full liner to be installed. Not Cheap.
Maintaining your cistern is a vital part of home ownership here and having it done professionally is a worthwhile investment. IMO

Well I haven't been on this Island for over 30 generations, like some, but I have done some thing that have made my cistern water potable and safe to drink.

First I have 2, 15,000 gallon cisterns, both have been cleaned in the past but were exposed to rain water directly from my roof that had lots of stuff in it.

I first installed (myself) a simple filter system bought from Home Depot and a adequate sized UV purifier that I bought online and had shipped here for about 1/2 the price an equivalent one would cost here. BTW according to my tests it's working fine.

Then the best thing I have installed was this:

From these guys(wealth of info):

What has happened is that a lll the organic matter that was in my cisterns has now deteriorated and without the addition of more I can now clearly see the bottoms of both cisterns.

And I add no bleach to my water!

I am interest in installing a whole house uv system.

How can I contact you

What is the name of the plumber who installs whole house uv systems

@peterisgreat Your replying to an 8 year old post.  What island are you on?  Any plumber can do it, seeing I was able to do mine by myself.  If you are on St. Croix, go to gallows bay hardware they have one set up on an endcap.  This is the system I bought, but purchased online and had it shipped in as it was 3-400 cheaper.  

WaterWorx on St John is having a moving sale from their retail location and have things on sale 20-40% off.  They have all kinds of filtration systems and components. You may want to check them out.  Www.waterworxUSVI.com

Greetings fellow Virgin Islanders,

I am a water professional and environmental engineer with 20 years experience in the Caribbean.  My career in the VI began with groundwater remediation in in the Tutu area of St. Thomas.  I then went on to operate and install several Seawater and Brackish Water Reverse Osmosis systems throughout the USVI and BVI. 

Over the decades of living in the VI, I have become intimately familiar with the unique aspects of our residential drinking water supply.  Whether the supply is rainwater stored in cisterns or tanks, or potable water from WAPA, good filtration is essential and UV is a good final step since no filter is perfect.

I am very passionate about water and preservation of our natural resources in the VI.  I have since started my own business: Ironwood Land Care and Water Treatment. My services include installation and rehabilitation of cistern filtration and UV systems.  Installation and rehabilitation of reverse osmosis systems.  I also offer services for troubleshooting and rehabilitating Aquaklear and other advanced wastewater treatment systems. 

If you are interested in any of the above services on St. Croix, please contact me at IronwoodSTX@gmail.com. For other islands I can offer consultant services and work with local contractors for installation. 

Thank you and have a great day!
