Home' NZ Dairy Farmer : February 2014 Contents THERE is legislation and regula-
tions that must be considered when
designing and constructing an FDE
pond. While a number of the statutes and
regulations relate to design, others simply
relate to the presence of a pond or tank.
The Resource Consent requirements
for FDE ponds in New Zealand depend
on which RC, DC, or unitary authority
the FDE pond is located within. These
organisations are also known as Building
Consent Authorities (BCAs).
The Building Consent requirements
required by the BA are intended to be
consistently applied across the country.
Even where consent is not needed there
is still a requirement to adhere to good
design principles and construction tech-
niques. The Building Code performance
requirements and Permitted Activity
standards in regional and district plans
must be met and adverse effects on the
environment must be minimised.
Farm Dairy Effluent containment
facilities (ponds and tanks) can present
two types of significant hazard.
First, an effluent pond may fail causing
the released effluent to harm people and
Second, a person, whether an employee
or not, may involuntarily enter a contain-
ment facility and suffer harm.
Containment failure hazards are best
addressed by farm owners ensuring
design and construction is undertaken
with competent advice. It is noted that
meeting BA requirements may partly
assist with meeting these and the HSE
requirements, but not all HSE require-
ments can be satisfied solely by comply-
ing with the BA.
A feature of the application of the HSE
Act to FDE containment facilities is that
no permit is required to operate, so there
is no confirmation of compliance before
any mishap. However, a mishap can
trigger an investigation, which can result
in punitive action if HSE requirements
are found to have not been met.
Should there be an accident involv-
ing such a system, then MBIE would be
looking at the design of the pond and
related systems ensuring that the HSE
Act, and attendant regulations regard-
ing the duties of designers and suppliers,
were being met using ''all practicable
steps'' available. So this could include
considering that although a structure is
built ''safely'', it still needs to be operated
with safe practices or protocols.
Fencing FDE containment facilities
is required under the farm's health and
safety policy. The appropriate type and
extent of fencing required for each farm
will vary and be dependent on the hazard
risks identified at the site. Where a site
contains hazards, which might attract
the unauthorized or unexpected entry
of the public, children, or wandering
animals (both small and large), then the
hazard needs to be enclosed to restrict
access. At the very least, a five wire fence,
preferably with netting and an electric
fence 'hot wire' should be constructed.
In some locations a higher fence such as
deer fencing will be appropriate. Lock-
able gates and hazard warning signage is

Pond legislation and regulations
A new development to a site built concrete
effluent tank is our Precast concrete panel
tank. Built with modular panels the tank can be
47, 70, 95, 110, 145, 190 and 300 cubic metre
sizes. The walls are assembled on site,
then the base is poured to complete the tank.
With a sloping floor and recess to take the
pump these tanks empty completely, thus
eliminating the common problem of crusting.
The Precast effluent tank can be
built in areas with high water tables and most
positions and situations.
With the increasing trend towards concrete
feed pads the Precast concrete effluent tank is
the complete answer to simple and effective
dairy shed waste management.
The tanks are completed with a safety fence
One-piece precast stone trap
2.6m wide x 2.2m long x 0.7m deep
The three piece stone trap uses precast
walls and back, the floor is then poured
2.8m wide x 5.0m long x 1.1m deep
4.0m wide x 5.0m long x 1.1m deep
With the drive through stone trap
the walls are precast with the floor
poured on site.

4.0m wide x 10.0m long x 1.1m deep
