Proper management of wastewater is one of the most important factors in ensuring a communities general health and surface water quality. Sanitary sewers are a modern construction. One of the most significant contributions to water quality was the Water Quality Act of 1972 setting requirements and enforcing standards nationally in the U.S.A.

A Sewer is a conduit for conveying wastewater either sanitary, industrial, or storm. Sewage is the liquid conveyed. Laterals, submains, trunk sewers, interceptors, outfalls are conduits to the treatment facility. Testing for groundwater infiltration or exfiltration seepage may indicate broken or cracked sewers.

Domestic sewage is more than 99.9% water and 0.5% dissolved and suspended solids. The strength is determined by the level of organic matter. The sewer system must be designed to transport the suspended solids from domestic fecal material and laundry and kitchen waste.

Sewage flow from commercial, business and industrial establishments is generated during operating hours. Very little flows nights, weekends, and holidays. Sewage from homes peaks between 7-10 A.M. and again, 6-10 P.M. Sewage flow from a home is very close to water use.

The sewers are buried but must be able to carry loads without breaking or cracking. The engineering can lessen the load by keeping the trench as narrow as practical and by requiring good bedding and backfill reinforce the conduit. Sewers should be buried below the freeze depth of a minimum of 3 feet of cover.

How about that $500 000 snapshot of the septic sewer and storm sewers voted on by Northglenn City Council by a subcontractor, when the City owns its own sewer photo truck just without the technical people to operate it, because they laid off 11 personnel when the mis-accounted for the $2 Million of Taxpayer $$$. So rather than hiring 8 team members to surplant the 11 lost, and train for the future, now, we have a truck,and a 1/2 Million Dollar "SNAPSHOT."
