Tank Installation: Civil Works Guidelines

General Notes: The design assumes good ground as defined by the New Zealand building code. If the site does not conform to this good ground assumption, please contact Solid Products for further advice. The installer shall ensure that the stability, strength, and long-term bearing capacity of founding soils is adequate for the imposed load. Loading: Design assumes roof soil load of up to 500mm burial depth and a further 1.5kPa light pedestrian surcharge. Not intended for vehicle loading. Ensure vehicles do not travel over the red hatched zone in the above illustration. Anti-floatation: Option 1: All uniformly buried water tanks shall have an adequate 300mm metal drainage blanket and Draincoil outlet where possible. The Draincoil outlet shall discharge into a free draining sealed stormwater connection located as close as possible to the base of the water tank to prevent flotation during high natural groundwater levels. Option 2: If a suitable stormwater connection is not available precast anti-floatation blocks can be installed. Please contact Solid Products for further advice.

DESIGN PRODUCER STATEMENT – PS1

ISSUED BY: David Smart Consulting Ltd

TO: MJ Custom Engineering Ltd

TO BE SUPPLIED TO: Territorial Authority

IN RESPECT OF: Underground Effluent Treatment Tank for up to 400mm burial and light pedestrian surcharge

LOCATION: Various Sites

David Smart Consulting Ltd has been engaged by MJ Custom Engineering Ltd on behalf of Solid Products to undertake structural design for Fibre Reinforced Concrete Effluent Treatment Tanks with roof soil load of up to 400mm burial depth over the lid and a further 1.5 kPa light pesdetrian surcharge loading.

Note: NOT INTENDED FOR USE UNDER RESIDENTIAL DRIVEWAYS.

The design has been undertaken in accordance with verification methods B1/VM1, B1/VM4 & B1/AS1 of the approved documents issued by the Ministry of Business, Innovation & Employment, for part only of the work as described below.

The work covered by this producer statement is as described under Revision A-04 of MJ Custom Engineering drawings A00841 titled Buried 400mm Cover-1 - sheets 1 to 3 with project reference “8000L Treatment Plant”.

Work covered by this Producer Statement includes;

• Design of concrete tank structures as detailed

On behalf of the Design Firm, and subject to;

• all proprietary products meeting performance specifications• the tanks being placed on good ground with 300 kPa ultimate bearing capacity in accordance with B1/AS1

I BELIEVE ON REASONABLE GROUNDS the effluent tanks, if constructed in accordance with the drawings & specifications, will comply with the relevant provisions of the New Zealand Building Code.

Signed: ...........................................……….. Date: 11 April 2019
