Legal
Background:
All American
conveyance system owners and operators are obliged to bring their sewer
system into compliance with the USA EPA regulations:
- Clean
Water Act (CWA)
- Capacity
Management Operation and Maintenance (CMOM)
- Government
Accounting Standards Board (GASB) Statement 34
Disappointing
Reality :
- Even
those who have spent millions on rehabilitation of municipal sewer
systems to reduce wet
- weather
overflows and sewer backups still have problems with Sanitary Sewer
Overflows (SSO)
- None
of the efforts managed to reduce the total infiltration and inflow
( I/I) more than 25 - 40 %
- Often
new and larger treatment plants have been constructed in order to
cope with the increased load of
- wastewater
instead of eliminating the I/I problem at its source
Legal
and Financial Concequences:
In consequence
of this disappointing result, conveyance owners are still threatened
by federal lawsuit and could
face millions in fines and additional sewer upgrades
The
source of the problem are:
- the
laterals - the private and municipal services lines - have been left
out of the rehabilitation efforts
- Service
laterals are the direct inflow sources for 60 -75 % of infiltration
which has not been addressed yet
The
Solutions for the problem:
SANIPOR®
uniquely placed to help US conveyance owner and operators under legal
threat
to meet the requirements and their deadlines better than any other technologies
available in the market
Why?
The entire conveyance system needs sealing
- The
majority of leaking sewer pipes have no structural deterioration
- Most
of them leak at the joints
In
other words:
- Most
of the structurally sound pipes still leak and suffer from infiltration
or exfiltration!
- They
do not need structural repair but sealing
Using available technology with the aim to reduce I/I
requires at least 3 separate methods :
- CIPP
- relining of mainlines
- manhole
- rehabilitation
- lateral
rehabilitation
All need to be done separately and in much longer time on much higher
costs
SANIPOR®
can do it all with one process.
