(CONSTRUCTION DEVELOPMENT CENTER)
The construction norms and technical documentation system had
been founded in 1960 by directly applying Soviet (former) construction
norms and rules.
In view of the Deputy Prime Minister of Mongolia’s resolution No.
42 dated 26 November 2012 about “Conducting state inspection on the
scientific and technical levels of national standards”, 600 professionals of
52 subcommittees had inspected and developed an assessment.
About 6200 standards, applicable all over Mongolia, had been
covered by the inspection and out of the total, including all standard types,
44.5 percent or 2,762 standards kept up with modern level or the same
level of standard as in international, regional and foreign countries.
1,135 standards or 18.3 percent out of the total had reached
international standard level, 97 standards or 1.6 percent regional level, and
910 or 14.7 percent the standard of a foreign country.
CONSTRUCTION NORMS, RULES , AND STANDARDS
IN NUMBERS
Out of the total number of 575 standards, applicable in construction and
public utilities sectors, 331 are maintained, 224 are re-examined, 112
are re-developed, and 20 are annulled. /findings of the state

A total number of 103
WWTPs are operating all
over the country, according
to findings of the inspection
carried out for operations
and equipment status of
the treatment facilities.
Out of the total, 41 (39.8%)
had a regular operation
with treatment level that
met standards, 27 (26.2%)
had an irregular operation
and 35 (34.0%) were out of
operation.
Total regular
Out of the 36 households’ wastewater treatment facilities that had been examined by the General Agency for Specialized Inspection in 2013, the following operational timelines had been observed: some 39 percent in 1981-1990, 19 percent since 2001, 17percent in 1971-1980, 11 percent 1991-2000, and 11percent in 1961-1970.
Out of the aimags covered by the test, 66.7% had the suspended solids 4.9%-23.5 times more, 73.3% had the BOD 12.8%-9.3% times more, 33.5% the oxidation of permanganate 7.5%-25.8% times more, and 71.4% had the ammonia 22%-12.3 times more than the provided levels in the standards for treated effluent from WWTPs.

The Legal environment on wastewater has relatively been improved in
recent years and many norms, rules and standards are being updated.
In view of above circumstances, utilization rate has not been improved.
Untreated industrial sewage does not meet standards requirements for
discharging into the centralized network
Wrong technological selection
Insufficient controlling of applicable laws, CN&Rs, standards
implementation
This is causing increased pollution and generating conditions to affect
adversely on human health and nature environment
Conclusion
Improve legal environment
Improve design solution
Construction of good quality facilities
Introducing of new tools and technologies
Improve human resources capacity
Implement laws, rules, regulations and standards
