Septic installation costs?

Digger: $60/hr x 2hrs
Cylinder blocks: $.65 - $.80 aproximate 400-500 depending the size of the septic.
1-2 meters of sand: $35 - $45/meter
1-2 meters of gravel: $35 - 45/meter
45 minis of cement: $5/ea
22 rebarb 3/8": $2-$3/ea

Labor: $500-$800 for a week worth of work.

Usual size is a 5x5x5 solids with a 10x10x10 water. The dual tanks will allow for emptying the solids tank about every 10-15yrs depending of use. Or you can do a 15x15x10 with good soil drainage will last you over 10 years before having to empty it.

Do not poor clorox or grease in it, it will shorten the live of the septic system.

Thank you adlin20!  That is super helpful!

No problem!

We have one built on our property and only the black water goes to it. Use the grey water for the plants.

The one on my father in law is over 20 yrs old and hadn't been empty in over 20 years.

What about the sink water (soap) and the washing machine water which is likely to have chlorine?
How you separate all this stuff?

It never occurred to me I needed to worry about it, but I guess I do.

When we built the house, I had all the grey water diverted to the backyard. We don't use clorox for washing and use biodegradable soaps. We use products that do not contain chlorine in it. You saw my pics, the plants get all the water we use with the exemption of the black water.

That's my plan.  Small septic for "black water" and larger cistern for "grey water" for landscaping.  "Grey water" for those that don't know, comes from sinks, showers and laundry.  Use biodegradable soaps, and the water can be used to irrigate landscaping.  "Black water" comes from toilets and kitchen sink/dishwaher.  That goes into the septic, where bacteria break down the solids.

To keep the septic tank healthy, add some bacteria (Rid-X, e.g.) every now and then.  A little chlorine isn't going to kill all of the bacteria in your septic, but repeated and heavy doses can cause problems.

I grew up in the country.  Lived with septic most of my life.

You may also consider one of these septic tanks.

I only suggest it because not every septic tank in PR is up to code and they may leak or may have other problems.

I lived in the country part of my life but as a kid I never had to deal with a septic tank so I was unaware of its care, this has been very informative and interesting guys.

So I guess I will end up with 2 cisterns, one for clean water for emergencies, one for grey water (sink, shower, laundry) and a septic for dark waters (toilets and dish washer)

Yes, a very enlightening discussion, thanks!

If anyone else is interested, we have found this book to be a really big help in trying to plan the management of our potential PR home.  Some of these practices we already do here in Chicago.

WarnerW, I just have the tubing directly to the ground for the grey water. My land is sloppy so all the water flows down a ditch we have on the side of the house, it feeds all the plants on it's way downhill.

As you mentioned, we only use biodegradable soaps. Also, if you have a septic, it is not recommended to install a dishwasher. Since I retire, my second name is dish boy!

Rey,

You are going too high tech! LOL
Those tanks may be good for places where you need to contain all the use water, but been a close system it will need to be drained more frequently. When we built a septic tank in the island, the fist few rows of cylinder blocks are placed sideways to allow drainage, plus every so ofter, the bricks are space out. At 15-20' deep, there should be good drainage to allow for the water to be filtered naturally. There is a bed of gravel at the bottom to allow filtration as well.

You should not have a septic done close to a water source. And actually, if DRN happens to stop by, they will stop the construction if is done in close proximity to a river, lake or beach area.

Hello, do you have updated prices for 2024 installation of Septic Tanks Services?

@adlin20

Do you have the updated costs for installing a septic tank in 2024?

Hi!  Does anyone know where I can find the code for how many feet from a home the septic needs to be?   Under contract in aguada and seems the septic isn't quite 10 feet from house.   Cry now or cry later.  Trying to decide.

@msotolopez237 did you ever receive a reply

@Noel Cruz Secondary

Thank you Noel. This is very helpful. Bendiciones!!

Hello look septic systems are easily constructed by building a Solis footing with concrete  then build the walls  for a part ion making a solid and a liauid tank. Plaster both both tanks and the interior of both tanthanks the liquid sid you create a 4x4ft opening in the floor for the water to settle  reinforce the ceiling with rear and pour a 5 in roof on the tank with 4 in clean outs to pump for maintance in future years leave 28 x28 inch opening in each compartment to remove the wood and supports to frame the roof remove the wood and cement the openings closed install the 2 pvc 4 in clean outs before cementing the 18x18 temporary access simple cost effective superior quality tank can be guilt in a week with 3 men
