PIT INSTALLATION INSTRUCTIONS:

We strongly recommend that Stormwater collection and drainage systems for any site are designed to accept probable stormwater flow rates by a suitably qualified engineer, and to comply with any specifications for the site decided by the local regulatory authority or other project controller. The following installation instructions should be followed:

1. The prepared excavation should allow the Pit to be seated firmly on a layer of firmly compacted bedding sand with the upper surface of the Steel Grate or Cast Iron Frame, whichever is selected, at the proposed final surface level.

2. Mark and cut the Pit walls to accept the connection pipes or channels etc at the correct levels.

3. All pipes should be fitted through the Pit wall and sealed with a suitable silicone-based adhesive or sealant.

4. The Grate should be fitted to ensure that the Pit walls do not distort during the completion of the paving work. Internal bracing of larger Pits during backfilling is recommended. Braces for Series 450, 600 and 900 are provided.

5. Pour mass concrete at pipe entries outside the Pit walls to provide support to pipes entering the Pit walls.

6. Backfill the excavation with moderately compacted, clean, stabilised soil and sand.

7. Allow sufficient space above the backfill for a concrete collar to be poured around the Pit, finished at the final surface level. Collar depth and width should be the same, about 100mm for the Domestic Rainwater Pit and 100 to 150mm for the Series 300 Pit. Collars should extend to not less than 150mm below the rim for the Series 450, 600 and 900 Pits. This collar provides all-round support under the Pit rim for the Grate and protects the Pit against possible "in-service" mechanical damage to the edge of the rim. The diagram overleaf indicates concrete surrounds in both light and heavy traffic sites.

8. Surrounding bitumen, concrete or brick paving should be planned for completion with graded areas so that collected water flows towards the concrete collar surround and into the Pit.
