I want to Wethersfield to the department of health to pick up a drawing of my septic fields we measured out where are the fields were in a distribution boxes it turns out the first distribution box was damaged and not letting water through it so he replaced it and the system is working fine now."

"I do not hand out 5 star reviews just because. Steve and his team exceeded expectations. He replaced a septic tank and installed a dry well system just before the sale of my home to satisfy conditions to buy and he completed the work impeccably with minimal impact to the yard. He was exceptionally strategic, clean and neat while doing the work where others were making no promises or guarantees. I canâ t say enough good things about Fenn Construction."

"Professionalism at its finest. Received a call within minutes and having an emergency, they sent someone out same day. Having a hard time finding the part needed (the plumber went to 5 local places unbeknownst to us) he promised to be back first thing in AM with proper part that he would find in CT. I cannot recommend them enough for the speedy, and excellent work."

"I had a boiler installed with Go green express and I couldn't be happier with the results. The crew came in the morning and was out by the afternoon. They were very professional and left the work area spotless. The boiler they installed not only works great but looks great too. Everyone I showed it to was highly impressed. I received calls from GO GREEN after work was done to make sure i was completely satisfied , I can't ask for more then that. Good job GO GREEN EXPRESS …. Thank's David Melendez."

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

FAQs for septic system installation and replacement projects in Danbury, CT

The smallest standard septic system uses a 500-gallon tank, which costs between $875 and $1,150 installed. This size works well for single-occupant dwellings with minimal wastewater production. However, many local regulations specify minimum tank sizes, so check with your building department before committing to this compact option. Some jurisdictions require at least 750 gallons regardless of home size to ensure adequate waste processing capacity.

The installation timeline varies based on site conditions, permit processing, and contractor schedules. The process includes obtaining permits, conducting soil tests, excavation, tank placement, leach field construction, and final connections. Weather conditions, soil challenges, and inspection scheduling can all affect the overall timeline. It's wise to begin planning well in advance of when you need the system operational.

The most economical approach is to install a conventional anaerobic system with a plastic tank. To minimize costs while maintaining legality, obtain multiple quotes from licensed installers, consider scheduling during their slower seasons, and handle basic site preparation yourself. Never skip permits or required testing to save money—illegal installations can result in significant fines and mandatory removal, ultimately costing far more than doing it right initially.

Regular pumping helps prevent system failures and extends operational life. Most small systems require pumping every three to five years, though frequency depends on household size and usage patterns. Pumping services cost between $290 and $530, making this maintenance expense relatively minor compared to potential repair costs ranging from $500 to $2,600 for neglected systems. Establishing a regular maintenance schedule based on your installer's recommendations helps avoid costly emergency services.
