"Gallagher Grading did an excellent job removing 60 tons of landslide debris in two days. All excavation to dig out retaining walls, stairway, a garage and scraping and cleaning mud off my driveway was done with utmost care and no damage was incurred. Edward and his men were professional, prompt, quiet, well-mannered, and responsible. High work ethic coupled with very competitive and transparent pricing makes this company not to miss. No hidden charges, no price inflation. Job was run smoothly and efficiently and all precautions were made, taking the size of the 10 ton load trucks, not to disturb my neighbors here in Bel Air. For all excavation and grading services, I would highly recommend Gallagher Grading."

Professional installation of greywater irrigation and rainwater harvesting systems. Most people in Los Angeles water their plants with drinking water while letting perfectly usable water from bathtubs, showers and laundry go down the drain. Our systems recapture this lightly-used water and use it a second time for landscape irrigation. Greywater can be used on fruit trees, shade trees and larger ornamentals, it is not recommended for grass or native plants (which can get too much water). We also offer greywater system design, permitting, consultation, education, system maintenance and community workshops. Greywater Action level III installers; ARCSA Accredited Professionals (rainwater); Permaculture Design Certification; HERO verified contractors. (Graywater, Gray water, Grey water)

"Joe and the Greywater Corps team came out and provided an assessment of which recapture system would be best suited to our property. We went with a laundry to landscape system to irrigate three fruit trees in our backyard, which are now thriving. The system is easy to use (a valve next to our washer can be switched on and off as needed) and the installation was completed expertly and efficiently. I would absolutely recommend this team to anyone looking for a smart way of irrigating their landscape."

Septic Tanks questions, answered by experts

It only takes a few days for a septic tank to fill with water after a pro has pumped it. This is completely normal, and the water is a vital part of your septic system’s wastewater treatment process. The water that fills your tank days after pumping is not the same as the tank being filled with waste. You shouldn’t have to pump your septic system more than once every three to five years unless you have a tank that’s too small for your home’s water output or there’s a problem with your leach field. 

The costs depend on whether you are buying into an existing well or starting from scratch. The average well drilling cost is between $25 and $60 per foot. The average cost to repair a well is between $350 and $1500. If you have a shared agreement and a community association, there will be additional legal and administrative fees. 

Wells should be at least 100 feet deep for drinking water, but they may need to be deeper depending on the local geology, water quality, and your household’s water usage. Work with a qualified well drilling professional who can assess the appropriate depth for your well and test the water before drinking it.

Most shallow residential wells are somewhere between 25 and 50 feet deep. They are among the simplest well systems. Deeper wells usually involve drilling to a much greater depth. Water wells for household use are typically 100 to 500 feet deep, depending on local groundwater conditions. Some may be up to 1,000 feet deep or more. 

Yes, experts handle manual pumping, chemical flushing, and equipment use properly, ensuring thorough cleaning and legal compliance with disposal regulations.
