(3) Be designed and constructed to allow for routine maintenance.
(4) Be designed and constructed so as not to require maintenance more frequently than once in any three-year period under normally anticipated use.
(b) The access device required by G.S. 130A-335(f) shall provide access to each compartment of a septic tank for inspection and maintenance either by means of an opening in the top of the septic tank or by a riser assembly and shall include an appropriate cover. The access device shall:
(1) Be of sufficient size to facilitate inspection and service.
(2) Be designed and constructed to equal or exceed the minimum loading specifications applicable to the septic tank.
(3) Prevent water entry.
(4) Come to within six inches of the finished grade.
(5) Be visibly marked so that the access device can be readily located. (1998-126, s. 2; 2006-255, s. 4; 2006-264, s. 63(a).)
