Types of Municipal Water Systems
The general types of municipal water systems are:
1) Surface water
2) Ground water
SURFACE WATER: surface water consists mainly of lakes,ponds,rivers and streams. There are a total of 329 surface water supplies throughout the province with approximately 313 in active use. Characteristics of natural water are based on water quality, including the potential formation of THMs. among the natural factors hydrology, topography, geology, soil, vegetation, and climate are considered as key parameters to influence the water quality.
GROUND WATER: Ground water are those resources of water which lie beneath the earth surface. This water mainly consists of minerals and elements. it is enriched of various kind of elements. Municipal water treatment has been the backbone of our business since 1960’s. About water treatment or before treating water its type should be well known.
Sewage treatment Process: There are generally three stages primary, secondary and tertiary sewage treatment.
1) Primary Treatment consists of temporarily holding the sewage in a quiescent basin where heavy solids can settle to the bottom while oil , grease and lighter solids float to the surface. the settled and floating materials are removed and the remaining liquid may be discharged or subjected to secondary treatment
2) Secondary Treatment removes dissolved and suspended biological matter. secondary treatment is typically performed by indigenous, water-borne micro-organisms in a managed habitat. Sometimes secondary treatment requires a separation process to remove the micro-organisms from the treated water prior to discharge or tertiary treatment.
3) Tertiary Treatment is sometimes defined as anything more than primary and secondary treatment in order to allow rejection into a highly sensitive or fragile ecosystem ( estuaries, low- flow rivers, coral reefs). Treated water is sometimes disinfected chemically or physically ( for example by lagoons and microfilteration).
