Why Biodigesters

Key Merits of Biodigesters over traditional septic tanks

Biodigesters are by far more advantageous as compared to traditional septic tanks in all aspects. Here are just the top three advantages

Never Fill Up

A biodigester NEVER fills up. All the solid matter is naturally decomposed into water and odorless gases. Amount of water flashed in and produced by decomposing process is outlet through french drain(soakage)

Minimal Costs

Biodigesters are by far much less voluminous as compared to traditional septic tanks. Also, biodigestersnever fill up, this completely eliminates the exhauster costs

Environmentally Friendly

The biodigester is a far more environmentaly friendly way of storing and treating effluent waste compared to traditional septic tanks. Hallmark Builders' biodigesters are approved by NEMA and the Ministry of Environment, Water & Natural Resources
